Highest Good Energy: Conservation & Infrastructure

Energy infrastructure and conservation methods are foundational to the creation of self-sufficient and self-propagating teacher/demonstration communities, villages, and cities to be built around the world. This page is an open source and free-shared guide to the setup and expansion of net-zero (100% sustainable) energy infrastructure during the construction of teacher/demonstration hub food infrastructurevillage models, the Duplicable City Centerand beyond. Once on the property, we will further evolve the Highest Good energy® foundations and open source resources with additional implementation and research results of an even broader diversity of energy saving strategies and alternative energy infrastructure methodologies.

This page contains the following sections related to Highest Good Energy:


Highest Good Hub



One Community defines Highest Good energy as renewable and conscientious of the air, water, and land that we all share. It is also an active approach to energy saving strategies that we are implementing including semi-subterranean buildingshared social spaces, passive heating, cooling, and lighting, maximally efficient hot water heatingwater saving shower headsenergy saving lighting plans, and more. One Community’s Highest Good energy rollout is detailed below assuming zero initial energy infrastructure and starting with traditional generators, grid tying, and then building a comprehensive solar micro-grid capable of producing sufficient energy surplus in the summer to equal or surpass our supplemental energy purchased in the winter. This will make our energy production sustainably net-zero or net-positive. From there we will continue to expand the energy infrastructure with more solar, wind, or any newer technologies that become available and can be determined to be superior to other alternatives.



Highest Good energy, green energy, off the grid living, eco-living, going green, sustainable energyThe current global approach to energy is not sustainable. One Community sees open source sharing 100% sustainable/net-zero energy setup and expansion as part of the solution. We are doing this as energy infrastructure for newly-beginning teacher/demonstration hubs through well-established hubs of 400+ people. Our goal is to promote conservation, all sustainable energy providers and technologies, and the viability of complete energy sustainability. We see making small-to-large group energy self-sufficiency easier, more affordable, and more attractive as part of our comprehensive approach to evolving sustainability that will positively and permanently transform the world for everyone

Before One Community (or any off-grid teacher/demonstration community, village, or city) can begin construction of its primary structures, an initial team will need to move to the property to survey the land and begin food infrastructure preparation, finalize development plans, and create the “pre-infrastructure” that needs to exist to support the construction of the official One Community infrastructure. This group will need access to electrical power before much else can be done and we’ve determined that temporary mobile diesel generators are the best choice for this initial power. From that point forward, more extensive and permanent infrastructure will be built including a connection to the grid, battery storage, and solar and wind as the primary power sources. The generators will then serve as standby emergency backup supply.

What follows is the specific plan for this energy rollout starting with the initial survey team of 10-20 people through our first 400. As part of our open source goals, this rollout is designed and described in detail to help those interested in duplication. Additional details will be added as we complete them. We discuss the complete energy infrastructure implementation plan with the following sections:



Highest Good society, fulfilled living, enriched life, enriching life, living to live, how to live an enriched life, keeping it all running, sustainable living, social architecture, fulfilled living, thriving, thrivability, emotional sustainability, the good life, a new way to liveThe primary focus of the solution for the initial people to move onto the property must be providing electricity as quickly as possible. There is also a need for flexibility of the generated power in order to provide the group with access wherever we need it. This will be accomplished initially with two 100 kW diesel generators and a battery energy storage system. Installation of the solar array will begin in the second month, as part of the next phase.

Here is the cost analysis for this phase:

10-20 Person Energy Rollout Equipment Costs – Click for most current spreadsheet that includes links

* Cost as of 10/17.

Note: Eventually the generators will either be mounted permanently on slabs or just serve as mobile sources of construction power when required. As and when more permanent sources of electricity (grid connection, solar, wind) and storage are set-up, these generators will be disconnected to serve as backup for critical systems in case of a grid-tie emergency like a cut power line. Ideally we will also be able to phase them out completely at some point.


In the beginning, the objective is to satisfy the energy needs of the initial construction camp, transition kitchen and food self-sufficiency plan while beginning construction of the Earthbag Village, Duplicable City Center, food infrastructure, and Ultimate Classroom. The generators are sized for these requirements.

Landing Party Power Setup Overview


Mobile Diesel Generator

The reasoning behind having two 100 kW generators first is that they will provide intermittent and mobile power for use on miscellaneous work sites throughout the property. As part of generator add-ons, a sound enclosure, and a 250-gallon sub-base fuel tank is attached to both generators to provide enough fuel for about 3 days, since the per day fuel use for the landing party is estimated to be about 69 gallons, as explained in the following sections. Generator 1, to enable mobility, must be attached with a double-axle trailer which can be towed as a mobile generator unit to miscellaneous work sites. Generator 2 acts as a stationary backup supply and the battery pack acts as the stationary active supply. Extra fuel would be stored in a fuel bladder with a 2000 gallon capacity, enough for up to 28 days, after which it would need to be refilled from the closest gas station.

To appropriately size these generators, the complete power needs for the “Landing Party” have been analyzed. The total power and energy use at this stage is covered in detail in this spreadsheet. It includes the following key areas:

  • Large Construction Equipment: The process of composting, based on the soil amendment plan, involves the use of a shredder to crush larger materials into smaller individual particles. Also, construction during this stage will require cement, produced by using cement mixers.
  • Washers and Dryers: These will be the same ones used as part of the eco-laundry rollout. ENERGY STAR washers and dryers with lower water and energy needs are selected there, which when simultaneously operated, also add to the peak power requirement.
  • Transition Kitchen equipment: The energy needs of the kitchen equipment (refrigerator, electric countertop griddle, etc.), as mentioned in the transition kitchen cost analysis, are calculated here.
  • Heat: The most efficient option to heat a party of 20 people in temporary structures would be to use a “heat the person and not the room” approach with individual electric dish heaters and electric blankets.
  • Computers, mobile phones, and other appliances: For this stage, there will be a lot of designing, planning, and open source sharing carried out on computers. We estimate the energy needs as: 10 desktops = 1.75 kW, 10 Laptops = 0.75 kW. Total = 2.25 kW. Mobile phone energy requirements are negligible.
  • Heating and Pumping Water: The diesel generator system must have the capacity to power heating groundwater pumped from the wells to the the instantaneous water heaters and pumps of the hydronics system. Pumps will also be required to transport this water to the desired locations. The property already has a pump which we calculated to be sufficient for 10-20 people. The energy requirement would then simply be powering the instantaneous water heaters for bathing in temporary shower structures and cooking needs. One of the water heaters can simultaneously heat water for up to four showers and a sink. At this stage, a total of two of these would meet all needs involving cooking and bathing. These water heaters will later be repurposed into use in the eco-shower structures of the Earthbag Village.
  • Tools and Chargers for Construction: This stage will involve a lot of construction work at multiple sites, which would involve the use of various power tools. The following will meet our needs: Seven rechargeable combo kits including a Drill, Reciprocating Saw, Impact Driver, Circular Saw, and Grinder plus 5 additional Jig Saws and 3 additional Table Saws. These would include 30 × 2 Ah Lithium Ion batteries, which could be interchangeably used with different tools. At a time, the maximum charging load is assumed to be 15 batteries.
  • Lighting: Lighting needs for this stage would involve illuminating the transition kitchen, temporary sleep shelter, community night time workspace and the first Ultimate Classroom structure.

The peak power load is identified to be during the evening at 171.8 kW. Accounting for additional needs, and considering that this generator system will later serve as an emergency backup for the Earthbag Village (Pod 1) and Duplicable City Center, we multiply by a safety factor of 1.15 to arrive at a final estimate of required capacity at 200 kW.


For easy fuel storage, a trailer would provide mobility for frequent refueling at a biodiesel fueling station or delivery service. For more permanent storage a bladder might be the best and most low-cost solution.

Note: Fuel consumption per generated kW varies with electrical load when using a generator. The chart below shows average fuel consumption in relation to % output (load). Since this chart is for a 100 kW unit, the % load is equal to the kilowatt output (50% = 50 kW).

100 kW Generator Power Efficiency and Consumption Projections

100 kW Generator Power Efficiency and Consumption Projections



A look at the bi-hourly energy breakdown shows that the second generator’s capacity is not used optimally, since it sits idle over most the day. Also, since the generator does not operate at full load most of the time, a loss of efficiency takes place, which increases the fuel costs significantly. This also supports the rationale for 2 generators versus 1, because just using 1 generator would mean even more frequent use of that one generator at less than 100% efficiency. More specifically, looking at the bottom of the energy use breakdown spreadsheet, you can see that the efficiency of 2 generators working as needed to supply power provides a 35 cents per kWh yield, compared to regular household electricity costs of ~0.12 cents per kWh.

An alternative, efficient, and environmentally conscious way to satisfy the energy needs would be to use a battery energy storage system along with an energy management system. Such a system would ideally run the generator at 100% capacity for a particular number of hours, which would be divided between powering the daily needs and charging the battery. During times of the day when the battery storage is enough to power all needs, the generator could be turned off and the battery could be discharged. Another important note is that the power needs of the camp, at this stage, would be fluctuating as the various tools and appliances are plugged into and out of the system. Batteries, as a flexible power source, are better suited to serve these demand intermittencies compared to direct generator supply.

A forecast, such as the one demonstrated in the energy use breakdown, can be generated by the energy management system every day to anticipate the energy needs of the camp and plan the optimum sources for providing power at all times.

Looking again at the bottom of the energy use breakdown, you can see that this addition of batteries and the added ability to run a single generator for all power needs (with the second generator now only needed for backup) provides a 22.6 cents per kWh yield, compared to 35 cents per kWh yield with generators running to supply power as needed, and regular household electricity costs of ~0.12 cents per kWh. These savings guided our decision to add in batteries.

Also, once the solar microgrid and wind infrastructure are set up, a battery energy storage system will become a necessity. Since the storage system is modular, it can be repurposed as per the requirements of the rest of this energy infrastructure rollout. This approach is further supported by the reality that the cost of battery energy storage systems continues to drop with increasing research and development in the field.

All this said, the ideal energy infrastructure at this stage would therefore include:

  • Generator 1: 100 kW – Active
  • Generator 2: 100 kW – Standby for emergencies
  • Battery Storage System: 200 kWh – Active (estimated based on the maximum energy use during all times of the day)

As previously stated, all of this infrastructure will also transfer over for backup use (generators) and integrated use (batteries) as we’re completing construction of the Duplicable City Center and Earthbag Village.



Highest Good society, fulfilled living, enriched life, enriching life, living to live, how to live an enriched life, keeping it all running, sustainable living, social architecture, fulfilled living, thriving, thrivability, emotional sustainability, the good life, a new way to liveAfter the “landing party” has completed their site survey, identified the locations of all planned construction (specifically for buildings to be built in the first 5 years, plus long-term general plan), begun working on the infrastructure, and completed and gained approval for all the initial building plans, the rest of the Pioneer Team will move onto the property. At this point, grid connection will have been established for power supply to support construction as well as operation of a large-scale sustainable water heating system and other systems which will be coming online. Also, enough planning will have been done to begin working on the long-term energy infrastructure while still allowing for flexible power generation for construction needs. This means beginning to build the solar microgrid that will service the Duplicable City Center and Earthbag Village (Pod 1).

The action items for this stage of the energy infrastructure rollout are as follows:

  • Establish grid connection
  • Construct and bring the solar micro-grid online
  • Construct and bring the two net-zero bathrooms and first two communal eco-showers online
  • Use the generators as backup systems and to provide mobile power to remote construction sites
  • Expand the battery storage system to react to demand-response programs and also take advantage of time-of-use electricity pricing
  • Bring the first stage of the hydronic systems online using hot water tank, heat pump and additional instantaneous water heaters. Also order equipment for the large-scale phase of hydronic systems implementation that will happen with the Second Wave for 50-100 People

Note: Check THIS PAGE for a tutorial on 100% off-grid energy infrastructure.


Power production at this phase of construction will include implementation of the complete energy infrastructure needed for powering the Duplicable City Center and Earthbag Village (Pod 1). The portable generator/battery will be used for tool and other remote power needs (and main-site needs) until grid connection is established and operating as the primary power supply. During this time, the solar micro-grid will also be installed and brought online.

Net-zero Energy Foundations

First we will connect the grid supply and additional battery banks to the Energy Management System. We will then begin our transition to solar power by connecting the solar micro-grid to the system as quickly as possible to decrease use of the grid power and phase out the diesel generators.

Note: The battery bank does not need to be full-size yet, but must have the capability of increasing to that size in the future.

In order to size our solar array, and estimate the additional battery bank sizing and daily cost of electricity to operate, we estimated the power and energy needs for this first wave. The foundational data and estimates used for sizing are the same as that of the 10-20 initial survey team, but scaled up appropriately. Here’s what this looks like:

Highest Good Energy, power needs for 10-20 people living off-grid, energy assessment

Power Needs Calculations and Comparisons for 10-20 and 20-50 People – Click for the open source spreadsheet with the most current data



There will be additional power needs once the second group of 20-50 people arrive. They are included in the spreadsheet above and consist of the following areas:

  • Water: As the number of people increases to 50 with this first wave, as many as 4 additional instantaneous water heaters will be needed to heat water for bathing in the communal eco-showers. The second stage of the hydronics implementation now involves bringing a hot water tank and heat pump online too, and preparing for the next wave by laying down piping and ordering components required for construction of the large-scale hydronics components.
  • Lighting, Heating, Washers and Dryers, and Computers: For the purpose of an estimation, all these energy requirements will increase almost linearly with the additional number of people joining the team on the property. To account for these changes we took the initial survey team’s requirements as a base and scaled it to satisfy the living requirements of 50 people. Lighting will increase as the temporary sleeping camp increases in size, as will the number of computers, dish heaters, and electric blankets. The number of washers and dryers will remain the same but with more frequent loads for more people, also increasing our energy needs almost linearly to account for the additional 30 people.
  • Large Equipment and Tools: To support the heavy construction at this stage, the number of cement mixers and tools should triple compared to the previous stage. Construction for the Duplicable City Center and Earthbag Village (with the central Tropical Atrium) will start during this stage. These additional power requirements are factored in while estimating the daily operating costs.
  • Transition Kitchen Equipment: The transition kitchen equipment is designed to support cooking for up to 50 people. The energy needs for this section would thus remain the same as the previous stage. Construction of the Duplicable City Center kitchen will begin during this stage though, and be complete before beginning the 50-100 person wave.
  • Net-zero Bathrooms and Communal Shower Structures: During this stage, the two net-zero bathrooms and first two communal eco-showers will come online. Water heating will be provided by a combination of a heat pump, hot water tank, heat exchanger, and instantaneous water heaters. Also, some power will be required to enable flushing in the net-zero bathrooms, which is calculated and accounted for.

Looking at these increased power requirements for the 20-50 people wave, you will notice that the energy infrastructure must be more than doubled to supply enough electricity and continue construction. This is why it makes economic sense at this stage to plan for the longer term and onwards by connecting to the grid. This will assure reliable connectivity all day long during this transition to a permanent, large-scale, and sustainable solar micro-grid energy infrastructure foundation.




Highest Good society, fulfilled living, enriched life, enriching life, living to live, how to live an enriched life, keeping it all running, sustainable living, social architecture, fulfilled living, thriving, thrivability, emotional sustainability, the good life, a new way to liveBy now, construction of the initial components of One Community are in full swing and we’re ready to bring on additional team members to accelerate the pace of progress. Along with population increases we will see the demand for electrical power and hot water increase. For instance, the Duplicable City Center kitchen and large-scale laundry facility will both be fully operational during this time and draw considerable electric power. As the demand grows, we will increase taking advantage of the energy efficiencies that are associated with larger systems like these and implement additional energy reduction and conservation measures too.

Equipment Needed for this Phase Cost Details
175 kW generator + add-on options $24,949 175 – 350 kW (4200 – 8400 kWh/day possible with both 175 kW generators now up and running and the 100 kW generator as a more mobile backup)
1000 gallon Fuel Bladder $2,406.69 1000 gallon fuel bladder
Fuel for 6 months 175 kW Gen or (100 kW generator) $25,284.10*($29,248.13) @50% for 4.8 hours per day* (@50% for 8.4 hours / day)
Wind Turbine(s)? ?? We will have the necessary experience with our location to effectively evaluate this option by this point
Flow Battery | Forbes Article About This ?? This technology (or other large-scale options) should be ready for market by this time
Total 52,639.79 This number will meet our needs and the addition of wind turbines, flow batteries, or other options will only be considered if proven financially and sustainably superior to other options

* This is smaller for the same amount of energy production due to the increased efficiency of these generators when running at a higher percentage of its maximum.


As development continues, the hydronic systems become operational and the total load on the Energy Manager will increase. As energy saving measures are added, the load will decrease. Overall, our total demand for power, both hydronic and electrical, will increase. This construction period will be very energy-intensive and will require large amounts of fuel. The Duplicable City Center radiant heating will be the largest consumer of power (both hydronic and electric). Therefore, it will be beneficial to have the core energy system (all solar arrays) and some of the energy-reducing measures in place before the hydronic system is enabled. Further evaluation on the property will dictate whether wind power solutions are viable.

The following are the action steps for this phase of energy infrastructure development:

  • Start expanding the solar capabilities of the property.
    • Every kWh created by solar arrays reduces the amount of fuel that needs to be purchased and transported to the property
    • Experiment to identify best practices for our solar/electrical conversion
    • If possible, we may want to research creating biodiesel on the property to reduce our reliance on external fuel sources
  • Find a permanent position for the last of the 3 generators. We’ll be foregoing mobility, but we’ll need all the generators connected during this time of significant energy usage
  • Make a decision about the wind turbines and large-scale and longer-term energy storage options

Related to the last bullet-point above, here are the viability projections for energy storage starting with small amounts of energy being stored for less than a day and progressing to megawatts being stored for a year or more. The red line is our power demand and what you see is that with storage capacity there is an amount of stored energy that can offset cost in the different mediums: batteries, compressed storage, etc. If we need to store power for 1 month, batteries are not a viable solution, but hydrogen storage would be once energy storage needs are sufficient to warrant the added expense of creating infrastructure like this.

Energy Details, One Community

Different Energy Storage Solutions



Highest Good society, fulfilled living, enriched life, enriching life, living to live, how to live an enriched life, keeping it all running, sustainable living, social architecture, fulfilled living, thriving, thrivability, emotional sustainability, the good life, a new way to liveThroughout the first five years on the property, One Community will construct several key structures. These will include the Duplicable City Center, the Earthbag Village (Pod 1)Straw Bale Village (Pod 2)food greenhouses, and additional village models if possible. The expectation from residents working in these areas and visitors touring our community will be that the solutions we are testing and displaying are genuine and practical solutions. During this time the Phase I energy system (described above) will be completely developed and the new focus will be testing and monitoring this system, fine tuning and conservation strategies, and planning and implementation of next steps.

Equipment Needed for this Phase Cost Details
To be determined TBD We will choose this development phase of energy infrastructure based on our open source duplicability goals and global transformation values and strategy. It will be paid for by our revenue streams.

This phase of development will be about monitoring all electrical energy being consumed and making expansion decisions based on needs and what we learn. The monitoring will be accomplished through meters for all individual living spaces and ammeters on any main power lines that would output the amps being used at that instant. Since the voltage will be known, the power will then be a simple calculation done by either a designed system or one bought off the shelf. That power (in Watts or kW) will then be logged over time to get the amount of energy in kWh used during the course of the day.

The following picture illustrates this with each “A” representing a monitoring point that communicates with a power display feeding data to central data analysis point:

Power monitoring example

Monitoring Electrical Energy Used by 100-400 People

Electrical Power Monitoring will have displays at the source and connections to a Main Power Display that will monitor and control electrical energy management sub-system.

Similarly, hot water used in showers, domestic use, and hydronic systems can be monitored by knowing the flow rate, temperature, and amount of time used. With instantaneous water heaters at points of service, the electrical energy draw from those units could also be used with the addition of the known hot-tank water temp and the flow rate of the use.

hot water monitoring, energy use

Hot Water Monitoring and Data Analysis

In short, hot water monitoring needs two pieces of data for each point: temperature and flow. For showers and the boiler, temperature can be replaced by an electrical power reading which will already be monitored by the electrical energy monitoring software and relayed to the Main Power Display. For everything else, temperature and flow monitors will do the job.

Specifically monitoring all of these things will allow us to fine tune our consumption patterns and open source share our results. Tracking these metrics for guests will also be a major benefit to the mission of One Community by showing the constant flow of temporary residents/visitors an accurate report of their energy usage while staying. In so doing, we help to educate people and give them the opportunity to become more conscientious about their use.

This will also create ultra-accurate energy needs assessments to help us with our planning and construction of each additional open source village needed for expansion to host people beyond the initial 400.



Sustainable energy, and renewable energy abundance, is all about careful planning and system redundancy. We won’t be able to effectively plan our power needs beyond the Earthbag Village (Pod 1) and Duplicable City Center until both of these components of our infrastructure are complete and we’ve gained the experience of using the systems designed above. While it is predictable that we will actually increase our energy efficiency over time due to increased conservation methods and “fine tuning” of our usage patterns, it is also predictable that we will have energy needs we haven’t accounted for.

Learning from experience, learning more about our specific property and how effective options like wind power may be, possible implementation of new energy technologies, and a better understanding of our specific needs will all be crucial to planning our power infrastructure for the Straw Bale Village (Pod 2) and beyond. Here are a few options we’ve explored to demonstrate cost differences and energy production potential.


Wind power is provided by turbines, which convert mechanical energy into electrical energy. Depending on how windy a property is, wind power can be a good complement to solar because it can provide energy 24 hours a day. Typically on an off-grid system wind power is used to charge the battery bank of the solar system at night. Below is a table listing some typical wind turbine capacities and costs:


Another lesser-known solar technology is the solar salt pond. The solar salt pond uses a salinity gradient to trap solar radiation in a large pond. The water heats up to 200 degrees Fahrenheit (93 degrees Celsius) and remains on the bottom of the pond due to the salinity of the water. This hot water can be used to heat liquids through a series of pipes on the bottom of the pond. The liquid in the pipes can in turn heat directly or produce electricity through an Organic Rankine Cycle Engine.

Several solar salt ponds have been demonstrated in Israel, Texas, and Australia. A half-acre solar salt pond with a depth of eight feet (2.4m) could provide 20 kWh of electricity day, night, summer, and winter.

The costs in constructing such a solar salt pond are listed below.

The advantages of using a solar salt pond for generating electricity include: no fuel costs, low maintenance, and 365 day/24-hour power generation. Disadvantages include: danger of spillage of saline water to environment, high initial investment, and large land usage.


We’ve already designed an extensive hydronic system that includes solar hot water. Expanding this system in the most intelligent manner possible will be based on our experience with the first system, technology advances, and clarification of expansion needs. As with solar PV systems, solar hot water systems are modular and this will provide us increased opportunities for expansion as our requirements and initial hydronic systems function and effectiveness becomes clear. For comparison, here are a couple typical solar hot water systems and their capacities.


We are contacted almost monthly with a new energy option. Once we are on the property we will have all our team in place and people can bring these ideas to demonstrate them. If we can verify a working model from someone willing to open source and free-share it with the world, we see no place better than an organization like ours to do so. We’ll also be able to consider funding addition research of such systems at that time.



One Community’s off-grid energy infrastructure to supply the Duplicable City Centerthe earthbag village (Pod 1), and aquaponics sustainable food infrastructure was initially assessed to require 283 kWh of power and we sized our photovoltaic solar power system to meet these needs. As per the energy self-sufficiency phase-in for 20-400+ people section above, these original assessments have proven far insufficient for our needs. Until we have completed our new needs analysis, we include here the details for the original system purposed to produce 283 kWh/day under average December sun conditions at the One Community property.

We have chosen a photovoltaic system as our initial energy infrastructure because these systems are dependable and capable of being shipped and duplicated anywhere in the world. We will use generators (as described aboveas back-ups to this PV system and intend to explore, demonstrate, and open source share whenever possible a diversity of additional energy options (see below) for expansion of our energy infrastructure for the straw bale village (Pod 2) and beyond.

As part of our self-sufficient and self-propagating teacher/demonstration communities, villages, and cities strategy our goal is to make duplication of a solar array like this as easy as possible through:

      1. Establishing relationships with companies willing to A) offer discounts to consumers for new-business direct referrals through us and B) affordably drop-ship these orders anywhere in the world
      2. Open source sharing videos and tutorials for the building and setup process
      3. Streamlining the process as much as possible for people by expanding existing sustainability networks to create complete package ordering options wherever they don’t already exist



Electric power requirements (see below) have been estimated by JP Novak of Build Native.com. The above system was then designed by Doug Pratt applying his 27 years of solar design and installation experience to confirm these estimates (below) seem reasonable. Estimating how people will use power in advance is always a guessing game and our initial guess missed the mark when we A) realized rocket mass heaters would not be a viable option for the earthbag village and B) that heating the Duplicable City Center and operating the large-scale kitchen was going to be far more energy intensive than we originally expected.

So now we are redesigning the above system with precision and all the new details of our ongoing development progress. Also, it is important to state that humans are nothing if not variable and we anticipate that this system will almost certainly require some fine-tuning even though we are doing our best to account for even the most minute details. We also anticipate that our group will learn from experience and probably become more energy aware and conservative with time. To help us gather data and fine-tune our process as part of our open source sharing, we will be using simple metering on all homes, the Duplicable City Center, and the aquaponics systems. By doing this we will be able to identify “energy hogs” and share this data, our solutions, and the objective energy saving results of our solutions.

The total electrical use for the earthbag villageaquaponics, and the Duplicable City Center, on a yearly average, was initially estimated to be 282.5 kWh per day. This is the figure used to size the solar electric system. In addition, all the AC appliances that were likely to be on simultaneously were totaled up. These included a percentage of lights, laptops, microwaves in the homes, along with all the aquaponics hardware, and most of the kitchen and community center lighting and hardware (including the hot tub). This max AC surge was about 76 kW and was the figure used to size the inverter pack.

Okay, so how do we go from kWh per day to PV arrays on the ground, and battery sizing, and inverter sizing, etc.? Here’s how Doug described it for us:

Highest Good society, fulfilled living, enriched life, enriching life, living to live, how to live an enriched life, keeping it all running, sustainable living, social architecture, fulfilled living, thriving, thrivability, emotional sustainability, the good life, a new way to liveLooking at available sunlight for the property: The National Renewable Energy Labs (NREL) went out and measured sunlight availability for several hundred sites across the U.S., and they did it for 30 years. 1960 thru 1990. So we’ve got a nice average. This is the “NREL Redbook”, and is the standard source for estimating sunlight availability at any point in the U.S., for any time of year. For our location we have a yearly average of 5.9 hrs of peak sun per day. Peak sun? What’s that? That’s the scientific definition of full sunlight on the Earth’s surface. A “full sun” is defined as 1,000 watts per square meter. Now it’s immediately apparent that’s an impossibly round figure. And you’re right. Reality on the ground varies widely depending on humidity, altitude, sun angle, and a host of other variables called “the weather.” What NREL has done for us is to take all the hours of sunlight on a particular site and condense it down, as if all the hours were at perfect solar noon – 5.9 peak hours in this case. Which is pretty handy, because PV modules are rated to produce a certain amount of power at “full sun.” If we know a site averages a certain number of peak hours of sunlight, we can closely estimate how much power a given PV array will deliver. Now, a warning here, we’re talking about the weather. And it varies from year to year. In fact the NREL data clearly demonstrates that it varies by plus or minus 9% yearly. So it’s not worth getting too hyper-sensitive to accuracy with our system sizing, as there’s bound to be yearly variations.

5.9 hours is the yearly average sun for our location. In December, at the lowest, it drops to 4.4 hours, which is still pretty good as solar sites go. For a December site, it’s excellent, and we’re going to use the 4.4 hour figure for PV system sizing. Now we know how many kWh per day your complex needs, we know what the average sun is going to be in December, what’s left is system efficiency. How much is lost to wiring, dusty modules, batteries, inverters, etc? Real world measured efficiency for battery-based systems ranges from 50% to 70%. Since much of the energy in this system will be used during daylight hours and will not need to be stored in batteries, I’m giving this system a fairly high 65% efficiency rating. This is completely seat of the pants estimation based on experience with large battery- based systems.

So we’ve got a 282.5 kWh nut to crack with 4.4 hours of peak sun and a 65% efficient collection and delivery system.

282.5 kWh / 4.4hrs / 65% = 98.77 kW of PV required. How many of what PV module is left until later, probably until right before purchase as prices and module brands have been shifting rapidly.


Highest Good society, fulfilled living, enriched life, enriching life, living to live, how to live an enriched life, keeping it all running, sustainable living, social architecture, fulfilled living, thriving, thrivability, emotional sustainability, the good life, a new way to liveBatteries are the largest expense for the system. Lead prices just keep rising as the world becomes more industrialized. Lead-acid batteries still represent the best buy for remote systems. (And before you ask, lithium-ion batteries are still at least 4-5 times more expensive, and haven’t proved they’ll last longer than lead-acid. Who hasn’t had problems with phone or laptop batteries?)

When sizing off-grid battery packs we usually aim for about 2 to 3 days worth of storage capacity. Less capacity means the batteries get cycled deeply on a day to day basis, which isn’t good for life expectancy. More capacity raises the cost to where it’s cheaper to start the backup generator to meet the occasional shortfall.

Batteries are sized by amp-hours rather than watt-hours, so we have to divide our watt-hour figure by the battery voltage – 48-volt in this case. (If you remember your high school physics, watts divided by volts equals amps. Or volts times amps equals watts.) We also have to factor in how deeply we’re willing to cycle our batteries. The true deep-cycle batteries we’ll be using will tolerate cycles down to 80% depth of discharge (DOD), but again, deep cycles aren’t good for life expectancy, so we’re going to draw the line at 70% DOD. Considering the high quality of the Unigy II batteries we’ll be using, along with reasonable cycle depth, this battery pack should enjoy a 15 to 20 year life expectancy. By which point lithium-ion batteries may be a better choice. That’s a bridge to cross when we get there.

282,500 watt-hours x 2.5 days / 48 volt / 70% = 21,019 amp-hours @ 48v. This is one honkin’ BIG battery! To help make it more manageable, we’re going to use an SMA Sunny Island Multi-Cluster inverter package which divides the inverters up into four separate nodes, with each node having its own battery pack. And that brings us to Inverter Sizing next.


Highest Good society, fulfilled living, enriched life, enriching life, living to live, how to live an enriched life, keeping it all running, sustainable living, social architecture, fulfilled living, thriving, thrivability, emotional sustainability, the good life, a new way to liveDoug chose the Sunny Island Multi-Cluster inverter package for several reasons. It’s highly reliable and adaptable German engineering at its best. It consists of 12 individual Sunny Island 6kW inverters wired as four groups of 3 inverters each. So 12 x 6kW = 72kW, very close to the max AC surge requirement we estimated earlier. (Each 6kW Sunny Island can deliver 8.4kW for 1 minute, or 11.0kW for 3 seconds for true surges.) Each node of 3 inverters will cover the A, B, and C phases of your 208vac 3-phase system. As power demand increases, the Multi-Cluster will activate more nodes as needed. So we won’t have a lot of inverter capacity turned on, using power, and just waiting for something to happen. Capacity will only get turned on as needed. Each node has its own battery pack, which will make the individual packs more manageable. And if any one inverter or battery pack needs service, that node can be shut down, while the rest of the system will still operate normally. Also, the Sunny Island system uses conventional high-voltage grid-tie inverters to process the incoming PV power. So transmission from PV arrays hundreds of feet away are much less of a problem.


While this system is designed to be largely automatic and self-sustaining, there will be one or more designated maintenance and service personnel for the community. This person will be in charge of system operations, and trained to be familiar and very comfortable with the Sunny Island system. In addition, a great deal of system automation is possible with the Sunny Islands. As battery state of charge drops to critical levels, the Island can initiate start-up of backup generators, and/or shut down selected loads (the hot tub for instance). Routine maintenance includes cleaning PV arrays, snugging up battery cables, and monitoring the Multi-Cluster for any warnings or problems. For this reason, someone dependable and knowledgeable will be “in charge” of the system at all times.




Highest Good energy, green energy, off the grid living, eco-living, going green, sustainable energyCompletely off-grid energy production in remote locations requires planning and a detailed phase-in process if the goal is to build as effectively and efficiently as possible. One Community is open source sharing our design process and rational as a foundation of establishing self-sufficient and self-propagating teacher/demonstration communities, villages, and cities. We will evolve this page with more details as they develop. These details will eventually include complete installation tutorials, maintenance details, purchase order specifics, and more.



Q: How are the generators sized?

Generators are sized using the maximum continuous wattage (power) that they can reliably create. If, when every device is turned on and running at maximum, the power draw is 95 kW then we select a 100 kW generator. Most of the time the power draw on the generator will be much less than the maximum load.

Q: How is the system sized?

The energy system will always be designed for the worst-case, maximum load. This would include sizing wires, fuses, and busses to handle every possible device and appliance turned on at once. Even though this is a very unlikely scenario, it ensures that the system will always work within its safe limits.

Q: In what case would the generators activate?

In the beginning we will use the generators for many different activities, but as the project adds sustainable energy sources to the property the generators will be phased-out in favor of the more sustainable options. However, we will keep the generators on site, in running order and fueled in case of a fault in any part of the energy management system. Or to as make-up energy for the system.

Q: What happens in the case of a massive battery fault?

In this scenario the battery banks are damaged or in some way inhibited from providing the stored power back to the energy manager. As the energy manager senses the drop (or stop) of battery power it will send a “Start” command to the backup generators causing them to start, reach working RPM, and sync into the energy manager’s grid. During this time the total load of the project less the total amount being created by sustainable means at that instant would be placed on the generators. They would run until battery storage was back online or the sustainable systems were creating enough power to cover the current load.

Q: What happens when there is not enough power to charge the batteries? (Cloudy Week Scenario)

Sometimes there will be a deficit of energy created in the day (solar, wind…etc.) and the remaining energy needed will have to be “made up.” The energy manager will run one or more generators at the most fuel efficient load for as long as it takes to charge the system. Once charged, the energy manager will automatically shut down the generators. In times of low light due to atmospheric disturbances this could become a daily occurrence to meet the forecasted demands on the system.

An example would be the energy manager calculating the amount of energy in storage and if the stored power does not meet the energy needs of the system for the next 24 hours the generators would run after the solar cycle (evening) to “top off” the batteries for the following day.

Q: What happens in the case of an energy manager malfunction?

In the case that the energy manager fails to operate or detects a fault, the system would go under total generator control. Because improper battery management can cause catastrophic damage, it is safer to allow the generators to take on the entire load of the system and remain in that state until the energy manager fault is discovered and fixed.

Q: How does the system change in an emergency scenario?

As a fault is detected in the system the energy manager, programed in advance, will compensate by utilizing the different power storage and production equipment options that are connected to the system.

Normal management would be the phasing in and out of sustainable power sources as they come online. However, in the event that a subsystem fails in such a way that could be damaging the entire system, like a short circuit or an unexpected voltage spike, the manager will remove the offending device from the system and rely on other sources. Mechanical systems (fuses, breakers) will also be in place in the case of a very sudden change in voltages that could be too quick for the manager to compensate, such as a lightning strike or short.

Q: What are the fail-safe measures?

Whenever possible all parts of the system will be designed to fail in a way that provides the safest possible scenario for the rest of the system. Whenever possible the system will also continue to provide power. This said, there could still be times where a catastrophic failure fail-safe would be to cut power completely. The details of this system of fail-safes would depend on the environment in which the system is placed and it’s particular construction and components, so at this time there are no definitive plans.

Q: What systems would be active in a power emergency?

In a power emergency only essential systems should be left on. The following factors would determine which systems are essential:

  1. The severity of the power emergency: The more severe the emergency, the more systems that would need to be turned off.
  2. The season: Heaters, for example, would be non-priority in the middle of summer and crucial in the winter.
  3. Consideration of how often a specific unit is drawing power: If the system is off most of the time it might not hurt to leave that unit in an off state.
  4. The power draw: If the the hot tub circuit draws 200 times the power that the lights in the Duplicable City Center does, it would be useful to turn that device off, before the lights go out.
  5. Importance of systems: As in the hot tub example in #4, systems that closely relate to human basic needs (food, shelter, water, etc.) should be prioritized. To make power conservation easy in an emergency, priority circuits should be marked both physically and in the energy controller.

To help put the energy needs of different systems in different situations into perspective, here is a chart showing how much specific components of One Community will contribute to peak wattage needs:

Emergency Power Peak Wattage Pairto

Emergency Power PEAK Wattage Needs Assessment

Now compare this to this chart that shows how much specific components of One Community will contribute to total energy needs:

Emergency Power Total Wattage Needs Assessment

Emergency Power TOTAL Wattage Needs Assessment

The point of these two charts is to show that components like the heat pump, dryer, and water heaters draw the most power from the perspective of total daily needs because they will be running consistently. Individual heaters, the boiler/water heaters, dryer, and parabolic heaters are the top contributors to peak wattage (energy spikes) because they draw a lot of power at one time. The general trend is still that those items high on one chart are also high on the other chart, but the details will vary and this can be extremely helpful to understand and consider in emergency power situations. Also, to conserve power, the hot tub (a huge energy consumer) has been designated as an item to be used only when surplus energy is available (like in the summer months).

Q: How much bio-diesel will you need?

The fuel source should be sized to provide enough for the running of the generator to meet team power needs for at least the amount of time the team is planning on this phase multiplied by a safety factor of 1.2. For the Landing Party of 20 people we assume that we will be using roughly 4.2 kWh/day per person (from Pod 1 per capita energy consumption). Over the course of the day we can assume that we run the generator for 5 hours continuously per day meaning that during that 5 hours the generator is running at 16.8 kW or 16.8%. Using the graph in the related section above, we find that the 100 kW generator will consume 3.34 gallons per hour at that load. Multiplying the number of hours by the fuel consumption rate gives us 16.7 gallons/day times our safety factor of 1.2 gives us a final value of 20 gallons per day for the average day.

Fuel storage on site would then be divided by 20 gallons per day to give us the number of days the fuel source can sustain the party. The 100 kW generator with the 250 gallon base tank would last the party roughly 12.5 days without filling. Fuel for an entire month would be 620 gallons total. At today’s prices that would come to roughly $2,480 per month for normal or $2,000 for farm diesel.

Q: What are the benefits of bladder storage for fuel?

Storing fuel in a large bladder is by far the most economical way to store the biodiesel used by the generators. However, bladders are flimsy and easily punctured. They cannot be buried either, so they would have to sit on the ground somewhere protected from heat-sources, and sharp objects.

Q: What are the benefits of tank storage for fuel?

While Tanks are more expensive than bladders, they can be buried to keep them away from heat sources and punctures. Larger tanks would take a large piece of land-moving equipment to place underground.

Q: How long will the batteries take to drain?

Very simply, batteries are rated with their voltage (average) and Amp-Hours. A 50 A-hr 12-volt car battery will provide 1 amp at 12 volts for 50 hours, or 50 amps for 1 hour, or 25 amps for 2 hours, etc. This is the principle used to size the batteries needed on the property. Knowing that we need to provide a certain amount of power (lets say 5 kW) over a certain amount of time (2.5 days = 60 hours) we can start to calculate the batteries needed.

Typical high-voltage batteries can be around 48 volts. Knowing that Volts X Amps = Watts, we can determine the number of amp hours needed:

  • 48 volts X (?) amps = 5000 W (5 kW)
  • (?) amps = 5000 W / 48 volts = 105 amps (rounded)

Since we need that over the course of 60 hours:

  • 105 amps * 60 hours = 6300 amp-hours

If the largest size of battery we can find is 1000 A-H, then we would have to buy 7 of them to cover this draw for 2.5 days.

  • 6300 A-H / 1000 A-H = 6.3 → 7

As with all engineering calculations, the largest (predicted) average power drain will be taken into account to build in a buffer to our system.

Q: What sets One Community apart from similar projects?

One Community's open source project-launch blueprinting strategy and the fact that we are open sourcing and addressing ALL elements of society simultaneously are a combination unique to our organization. Together, these will help others duplicate what we do and create self-propagating teacher/demonstration communities, villages, and cities capable of positively impacting every single person on this planet within one generation.

Q: What sets One Community's open source goals apart from similar projects?

To our knowledge, no other project exists that is providing the comprehensive nature and detail of everything we are open source project-launch blueprinting.

Q: What is the specific One Community short-term goal?

  1. To become a world leader in global-solution information content within 6 months of moving onto the property as detailed in our open source project-launch blueprinting page.
  2. To expand within 5 years to a community of 200 full-time residents producing ongoing tools, resources, and tutorials while hosting thousands of annual visitors as outlined in our long-term vision page.
  3. To define the global-solution industry itself as an open source industry, expanding mainstream awareness, appeal, and desire for comprehensive sustainability by demonstrating and sharing a more attractive and fulfilling way of living that people can have if they desire to create it also.
  4. To teach as many people as possible to duplicate and/or evolve our global transformation model.

Q: What is the ultimate One Community long-term goal?

To transform our world into a sustainable and happier one through teacher/demonstration communities, villages, and cities to be built all over the world. We will work with these hubs as our open source partners and fellow leaders of the open source, Highest Good of All, and sustainable planet movement leading to a New Golden Age of cooperation, collaboration, innovation, creativity, sustainable living, and increased happiness for the entire human organism.

Q: How is One Community funded?

Q: Why not just build a small-scale prototype home or community that includes a minimum-scale revenue-generating demonstration/operation? Wouldn't this get things going faster?

This already exists as Airbnb and people are doing amazing with it, so small-scale operations are not what we see as missing. What we see as missing is a complete model for self-sufficiency that is open source and reasonably replicable. Even complete models for self-sufficiency already exist in the form of the many eco-villages out there, what none of those offer though is any sort of understanding and/or path for how average people with average means can replicate them. We also think there isn’t enough of a compelling reason for most people to bother with changing how they live now to engage such a path/project, so our project is purposed to provide and demonstrate that too.

From a total global-change perspective though, we think it is even more important to create a permanent place dedicated to open source and capable of providing for the complete needs of hundreds of people working on open source creations full-time, with enough revenue generation and space for expansion to grow to over a 1000+ full-time volunteers while also being able to support the establishment of other open source teacher/demonstration/R&D hubs around the world. This is why the intended propertyvillage models, and social architecture and economic focuses are all big.

To support faster and broader implementation while working on these big goals, we are also taking the extra time necessary to develop everything so it is modular and also implementable as individual components. This will allow for anyone who doesn’t desire the full teacher/demonstration hub approach to have options too, but our primary goal is to demonstrate the complete teacher/demonstration hub as easy enough, affordable enough, and attractive enough for average people with average means to want to replicate it and/or use what we provide to build their own version.

Q: If you are giving everything away through open source, how do you intend to make money?

Our model is designed to prosper specifically because we are giving everything away through open source project-launch blueprinting. We accomplish this through eco-tourism marketed with the open source infrastructure we have already created and other supported revenue streams outlined on our revenue streams page. All of this further promotes our model of spreading sustainability and actively promoting and distributing even more open source blueprints for duplication by as many people as possible.

Q: How will this help people in Third World countries and other areas where resources are needed most?

Using the four-phase strategy above, we wish to demonstrate building a teacher/demonstration community, village, and/or city as profitable for large investors and/or a way for small groups of people to pool what resources they have and get out of debt. We see this spreading and bringing resources to the areas that need them most because building these villages in these areas will be more affordable and easier to do with less building restrictions.

Q: How do you stop the model from being totally capitalized without the positive intent of the original model? 

We are not focused on putting limitations on the use of everything we are creating because of our open source commitment. We will, however, directly support any organization contributing specifically to open source project-launch blueprinting and operating for The Highest Good of All.
