How Much Energy is Enough for Each of Us? New Report Calls for a Minimum Standard

The idea that everyone should have access to sufficient energy lies at the heart of the microgrid proposition. 

Modern Energy Minimum

People may experience energy deficiencies because of poverty, geography or calamity. It may be a daily condition, as we see in parts of Africa, or a temporary condition brought on by storms or wildfires, as is more common in North America. In all of these circumstances, microgrids are being built to ensure reliable energy.

Not having enough energy causes both personal and economic hardship. But how much is enough? And enough for what?

A report released today by the nonprofit Energy for Growth Hub and The Rockefeller Foundation attempts to answer that question and calls for the creation of a new modern energy minimum.

In its mission, the report cited the United Nations (UN) Sustainable Development Goals, a 115-country agreement reached in 2015 that, among other things, calls for “affordable, reliable, sustainable and modern energy for all.”

Increasing income with energy

Reaching the UN’s goal will be nearly impossible under the International Energy Agency’s (IEA) current minimum standard, which is about 50 kWh per capita per year in rural areas and 100 kWh in urban areas.

What does that much energy give you? A few lightbulbs a few hours a day, a phone charge and the occasional running of a fan, according to the report, “The Modern Energy Minimum: The Case for a New Global Electricity Consumption Threshold.”

“For this reason, the current annual consumption threshold of 100 kWh is better thought of as an extreme energy poverty line, rather than as the international energy target for promoting development and greater incomes,” the report said. “Just as income is tracked above a poverty line and at other higher levels, the same framework could be applied to electricity consumption.”

The current standard fails to capture energy use outside the home. This shortcoming is meaningful, according to the report, because nonhouse use accounts for 70% of global electricity consumption. More importantly, power use outside the home drives economic activity.

“Just as income is tracked above a poverty line and at other higher levels, the same framework could be applied to electricity consumption.”

“If higher electricity consumption is supposed to help drive incomes higher, we should be paying at least as much attention to nonresidential uses,” said the report.

And the problem isn’t just lack of power but lack of reliable power.

California’s Critical Facility Challenge: The Case for Energy-as-a-Service Municipal Microgrids
If California does not modernize its grid and power delivery infrastructure via sustainable premium power provided by microgrids, the state will be thwarted in its efforts to meet not only its economic and public safety needs, but aggressive carbon reduction and renewable energy goals.

The negative impact of power outages, which include both unavailability of supply and low quality of power, are profound on firms, especially in Africa. Firms in low-energy consumption environments widely self-report that the cost and reliability of power is a first-order obstacle to productivity, employment and expansion,” the report said.

Modern energy minimum 1,000 kWh

Energy for Growth Hub and The Rockefeller Foundation are calling for a minimum standard of at least 1,000 kWh per person, of which 300 kWh would be assigned to the home and 700 kWh to other sectors, such as industry, commerce, transportation, agriculture and public services. 

“At a practical level, the Modern Energy Minimum provides a target that could be used to influence planning and investment decisions by governments and the allocation of resources by the international community. And it should provide some guidance for prioritization and sequencing of policies and investments in the power sector,” said the report.

As a next step, the authors suggest that an international body, such as the IEA, the UN or World Bank, begin collecting data based on the standard so that it could become an international indicator of progress.

The standard is likely to have more meaning in places where incomes are low — the 1,000 kWh metric correlates with an income of about $2,500 per year, roughly the midpoint for lower-middle income status globally, according to the report.

But even North America has felt the hardship of energy scarcity, albeit temporarily, with Puerto Rico experiencing the longest outage for the continent following Hurricane Maria.

The microgrid proposition

Microgrids are a targeted approach to quickly overcome energy scarcity, especially in remote areas of the world without access to the grid. That’s one of the reasons Microgrid Knowledge has made this type of microgrid a feature of its annual Greater Good Award.

Here are a few examples of how microgrids get it done:

    Consider the RV4 Hybrid:

    You got to have car so get a hybrid
    Besides its pure car utility, you get free a 18 kw power plant and battery

    so do the math!

    When one mentions India or Africa you are looking at a large populations distributed in small villages and towns with NO electricity at all. These homes are burning kerosene or candles for light and this fouls the indoor air quality and health. Going with solar PV and energy storage and a few LED lights allows lighting, by not having to buy and use kerosene or candles the cost of such items can go towards the cost of the nano or micro-grid on each home.

    “Not having enough energy causes both personal and economic hardship. But how much is enough? And enough for what?”

    In the U.S. we are looking at an “average” daily use of 36kWh to 46kWh. This is around 1.5kWh to 1.9kWh throughout a 24 hour day. In the desert southwest that’s about 10kWp solar PV array at 46kWh, for the north east the array would probably need to be up to 16kWp to do the same job. If one has the roof or better yet ground space, put in something like 15 kWp to 25kWp solar PV array to allow one to charge a BEV or two.

    Places like Africa and India have no real utility rate programs per se. In the U.S. utilities use TOU rates and demand charges to spike electricity rates that just so happen to “capture” on average more money per kWh used by ratepayers in their work-a-day routines. In the desert south west in the summertime and the north east in the wintertime are high load times of use. There are those with “relatively” energy efficient home construction that are using 3,500kWh/month in air conditioning loads that comes out to 167kWh a day or on average 7kWh for 24 hours a day. This kind of air conditioning load would require a south west home’s roof array to be in the 33.5kWp neighborhood or about 102 solar PV panels, (IF) you have the roof space or enough property to install such a ground mount system. In the north eastern U.S. to get this type of generation, you’d pretty much need a ground mount system with tracking in the east to west range for those (same) 102 solar PV panels or fixed ground mount with 170 solar PV modules.

    In other words, industrialized nations with their appliances screws up the “bell curve” for the rest of the World.
