The Energy Transition is about People Power

February 16, 2022

By now, you might have a pretty good sense of what the clean energy future looks like, at least from a technological standpoint. Maybe your neighbors are installing solar panels on their roof, or you’ve started driving a hybrid or electric car for your daily commute. But there’s a lot going on behind the scenes in the energy transition that might be less apparent. A key trend is the shift from top-down ownership and control of our energy system toward greater “people power.” So what does this mean?  

From centralized to decentralized energy

Most Americans still get their electricity from a relatively small number of big power players— utilities that, together with governments, set the rules for how energy is produced, distributed, and valued. But the growth in distributed energy resources—a fancy phrase for technologies like rooftop solar, electric vehicles, and energy storage—allows us to keep energy local, offering a chance to flip the current model on its head. Distributed resources, like solar and energy storage, can save us money on electricity costs, reduce pollution, and boost local economies, while being scalable and ready to deploy now.

By 2025, the combined capacity of these energy resources in the United States is projected to reach 387 gigawatts, driven by a whopping $110 billion in investment over a five-year period. Communities are embracing distributed energy as a way to tackle climate change and boost local resilience in the face of extreme weather events like wildfires and hurricanes. Falling costs for solar panels and batteries have made distributed resources increasingly affordable, especially when coupled with tax credits and rebates that soften the bite for everyday Americans. 

Power to the people

Distributed energy resources empower us in other, critical ways. Under the current energy structure, power monopolies have an outsized voice, not only influencing how the rules are made (and who they benefit), but also holding sway over our elected officials through lobbying dollars. Power companies typically extract wealth from our communities, with our utility bill payments leaving the local economy. The existing energy system isn’t just unfair and undemocratic—it reinforces centuries of structural racism, with the highest energy burdens falling on low-income communities and communities of color. 

The shift to distributed (decentralized) power can change all this. It creates opportunities for more dispersed patterns of ownership and control of energy production. It allows for a more democratic energy system where “we the people”—local communities, businesses, and households—take back our power by producing our own electricity. We gain more leverage in the energy system by being involved in the planning, funding, management, governance, and execution of clean energy projects. 

Greater people power can also lead to more equitable energy outcomes, helping to address race, class, and gender inequalities and enabling a just transition to a decarbonized energy system.

Examples of people power

The possibilities for energy democracy are diverse and growing. Here are just a few examples:

  • “Prosumer” households and businesses: At its simplest, we can take back control over our energy supply by installing a few solar panels at our home or business. In our new role as prosumers (both consumers and producers of energy), we can generate all or part of our own energy and even make money selling our excess generation back to the grid (if state policies allow it).
  • Community energy: At a collective level, we can join forces with our neighbors, a community group, or a local utility to create a community energy project, such as a solar array on a local church or a locally owned wind farm. As of 2019, there were around 834 community solar projects in the U.S., dominated by projects in Massachusetts, New York, Minnesota, and Colorado. 
  • Energy storage: By adding a battery bank, we can store the excess electricity we produce on-site for later use. The PowerBank Community Storage System in Mandurah, Australia, enables residents in one neighborhood to store their excess solar production in a shared Tesla Powerpack and then withdraw energy when they want, up to 8 kilowatts a day for a small daily fee. Similarly, vehicle-to-grid technology allows owners of electric vehicles (including school districts that own electric school buses) to store power in their vehicle batteries for later use or to feed back to the grid.
  • Aggregation: Some locales are making it possible to bundle, or aggregate, the power generated by multiple individual or community energy producers in order to make the electricity supply more reliable and consistent, and to make it easier for others to access and trade this power. Some places have combined several smaller distributed wind or solar resources into virtual power plants.
  • Peer-to-peer energy trading: Through this model, distributed energy producers use a digital trading platform to directly sell any excess power they produce to other local residents, essentially sidestepping the traditional utility relationship. For example, members of the Brooklyn Microgrid in New York City use a digital app to buy and sell energy on a local marketplace, helping prosumers profit from their extra production and giving their non-power-producing neighbors access to cheaper, clean energy.

Accelerating energy democracy

Despite the vast opportunity, many distributed energy technologies remain inaccessible or unaffordable to folks who lack the financing or who live in rental properties. To overcome some of these barriers, the 30 Million Solar Homes partnership aims to power 30 million U.S. households (about 1 in 4) with rooftop or community solar over a five-year period, including in historically marginalized communities. 

Power companies can support distributed clean energy by embracing new business models, like solar leasing, that share more of the benefits locally. The role of utilities will change with the shift in energy ownership. They may soon be paying us to access the distributed resources in our buildings, rooftops, and cars. As they strive to meet our preferences and demands, their political influence may weaken. 

Governments can facilitate energy democracy by supporting communities in the design, ownership, and management of energy systems. This includes embracing policies like net metering that compensate local producers, and supporting community energy projects through low-interest loans, preferential procurement, and by providing access to public spaces. Governments can also enact regulations that mandate the integration of local, community energy into neighborhood developments.

With the growth in distributed energy resources, it’s time to take control of our energy system. Ideally, we’ll get to the point where we can fully design our own energy mix, selecting the specific projects that generate the energy we want—whether from our own rooftops, from a neighbor’s solar installation, or from a local wind farm. With this shift in power, we could usher in an era of true energy democracy.

What’s the deal with these “100% clean energy days”?

October 20, 2021

Contrary to what your doomscroll-prone social media algorithms may be feeding you, there was a heartening glimmer of good climate news earlier this year. California’s electric grid reached almost 95% renewable energy: a record. The April 24 achievement came with a few asterisks—it lasted only a few seconds, and it didn’t cover the whole state. Still, it was a glimpse of this 100% clean energy future that we keep hearing about, one that sometimes feels more like shaky pledges than an imminent reality.

Happily, California’s renewable energy milestone is not that unique. Germany set a similar record a few years ago, maintaining a clean energy peak for several hours. China’s Qinghai province powered itself entirely on renewables for a week in 2017. South Australia has proven it can generate more than enough solar power to meet residents’ demands on a regular basis. Costa Rica has been running on nearly all clean electricity for years now, and so has the city of Burlington, Vermont. It’s gotten to be kind of a thing.

But why can’t California and other places do this all day, every day?

When you read about a place running on 100% clean energy, typically this refers to electricity. Which makes sense— If you want to make a big dent in planet-warming emissions, after all, the power sector is a good place to start. Forty percent of the world’s greenhouse gases come from burning coal, gas, and oil to keep the lights on, essentially.

So when California approached 95% percent renewable power last spring, it’s not as if its grid suddenly transformed from a pumpkin (with all due respect to lovers of pumpkin spice everything) to a green stagecoach, vanquishing fossil fuels along the way. California “was also burning a bunch of natural gas and exporting electricity to its Western neighbors,” noted a column in the Los Angeles Times. “It’s impossible to say exactly how much of the Golden State’s own supply was coming from renewables.”

Then what does it mean to be running entirely, or almost entirely, on clean energy? In California’s case, it simply meant the amount of renewable electricity (mostly from wind and solar) being generated was nearly enough to meet the amount of electricity needed to serve customers on that April 24 afternoon. On a recent October day, the figure was more like 56%.

It’s easy to imagine why this number fluctuates so much. If you have a sunny, breezy day with relatively mild temperatures, you’re going to have abundant wind and solar output—more than enough to meet the modest demand from customers who don’t need to crank the AC that day. On a cloudy, freezing day, not so much. Maybe there’s less output from renewables and more demand for heating.

You’ll remember from our newsletter a few weeks ago that wonderfully simple supply and demand graph? We want rising supplies of clean energy to meet demand as often and as soon as possible. The many states and cities pledging to achieve 100% clean energy need to achieve this balance, ensuring that zero-emissions sources can meet demand 24-7. How any given location achieves this depends on a variety of factors, including geographical location and the right policies. Iceland, for example, is able to rely on a wealth of underground heat to produce lots of geothermal energy. Costa Rica has a bunch of hydropower built into its clean energy win. California has geothermal and hydropower plants, too, but it also has a much bigger population. 

The Ready for 100 campaign shows the cities in the U.S. that have committed too 100% clean energy. See what city near you has committed: https://www.sierraclub.org/ready-for-100/map

For U.S. states, getting to 100% clean electricity is going to take a combination of actions. We will need to build out renewable energy projects and the transmission network to carry power from, say, outlying wind farms to cities. Energy storage will be needed for times when the sun isn’t shining and the wind isn’t blowing. Utility programs will help manage highs and lows of demand by rewarding customers for shifting their energy use to off-peak times—something increasingly possible, thanks to smart and programmable appliances. Power markets must be redesigned to reward zero-emissions sources.

It sounds complicated—and it is. But what we do know is that it’s achievable. After all, more than 100 cities around the world already get at least 70% of their electricity from renewable sources. And climate scientists have produced multiple studies showing how country after country could be running on clean energy. This research, along with the many real-world examples, shows us that with investment and political will, the U.S. and other countries can make good on their 100% clean energy pledges, at least as far as the grid goes.
