Energy-insecure households in the U.S. pay 27% more for electricity than others

Community Solar for Low-Income Homes expands energy equity by delivering renewable energy access, predictable bill savings, and tax credit benefits to renters and energy-insecure households, accelerating distributed generation and storage adoption nationwide.

 

Key Points

A program model enabling renters and LMI households to subscribe to off-site solar and save on utility bills.

✅ Earn bill credits from shared solar generation.

✅ Expands access for renters and LMI subscribers.

✅ Often paired with storage and IRA tax credit adders.

 

On a square-foot basis, the issue of inequality is made worse by higher costs for energy usage in the nation. Efforts like community solar programs such as Maryland community solar are underway to boost low-income participation in the cost benefits of renewable energy.

The Energy Information Administration (EIA) shows that households that are considered energy insecure, or those that have the inability to adequately meet basic household energy costs, are paying more for electricity than their wealthier counterparts. 

On average in the United States in 2020, households were billed about $1.04 per square foot for all energy sources. For homes that did not report energy insecurity, that average was $0.98 per square foot, while homes with energy insecurity issues paid an average of $1.24 per square foot for energy. This means that U.S. residents that need the most support on their energy bills are stuck with costs 27% higher than their neighbors on square-foot-basis.

EIA said energy-insecure households have reduced or forgone basic necessities to pay energy bills, kept their houses at unsafe temperatures because of energy cost concerns, or been unable to repair heating or cooling equipment because of cost.

In 2020, households with income less than $10,000 a year were billed an average of $1.31 per square foot for energy, while households making $100,000 or more were billed an average of $0.96 per square foot, said EIA. Renters paid considerably more ($1.28 per square foot) than owners ($0.98 per square foot). There were also considerable differences between regions, with New England solar growth sparking grid upgrade debates, ethnic groups and races, and insulation levels, as seen below.

The energy transition toward renewables like solar has offered price stability, amid record solar and storage growth nationwide, but thus far energy-insecure communities have relatively been left behind. A recent Berkeley Lab report, Residential Solar-Adopter Income and Demographic Trends, indicates that even though the rate of solar adoption among low-income residents is increasing (from 5% in 2010 to 11% in 2021), that segment of energy consumers remains under-represented among solar adopters, relative to its share of the population.


Community solar efforts

As such, the United States is targeting communities most impacted by energy costs that have not benefitted from the transition, highlighting “Energy Communities” that are eligible for an additional 10% tax credit through funds made possible by the Inflation Reduction Act.

Additionally, a push for community solar development is taking place nationwide to extend access to affordable solar energy to renters and other residents that aren’t able to leverage finances to invest in predictable, low-cost residential solar systems. The Biden Administration set a goal this year to sign up 5 million community solar households, achieving $1 billion in bill savings by 2025. The community solar model only represents about 8% of the total distributed solar capacity in the nation. This target would entail a jump from 3 GW installed capacity to 20 GW by the target year. The Department of Energy estimates community solar subscribers save an average of 20% on their bills.

California this year passed AB 2316, the Community Renewable Energy Act takes aim at four acute problems in the state’s power market: reliability amid rising outage risks, rates, climate and equity. The law creates a community renewable energy program, including community solar-plus-storage, supported by cheaper batteries, to overcome access barriers for nearly half of Californians who rent or have low incomes. Community solar typically involves customers subscribing to an off-site solar facility, receiving a utility bill credit for the power it generates.

“Community renewable energy is a proven powerful tool to help close California’s clean energy gap, bringing much needed relief to millions struggling with high housing costs and utility debt,” said Alexis Sutterman, energy equity program manager at the California Environmental Justice Alliance.

The program has energy equity baked into its structure, working to make sure Californians of all income levels participate in the benefits of the energy transition. Not only does it open solar access to renters, the law ensures that at least 51% of subscribers are low-income customers, which is expected to make projects eligible for a 10% tax credit adder under the IRA.

“The money’s on the table now,” said Jeff Cramer, president and chief executive of the Coalition for Community Solar Access. “While there are groups pushing for solar access for all, and states with strong legislation, there are other pockets of interest in surprising places in the United States. For example, Louisiana has no policy for community solar or support for low-income residents going solar but the city of New Orleans has its own utility commission with a community solar program. In Nebraska, forward-looking co-operatives have created community solar projects.

Community solar markets are active in 22 states, with more expected to come online in the future as states pursue 100% clean energy targets across the country. However, the market is expected to require strong community outreach efforts to foster trust and gain subscribers.

“There is a distrust of community solar initially in LMI communities as many have been burned before by retail energy false promises,” said Eric LaMora, executive director, community solar, Nautilus Solar on a panel at the Solar Energy Industries Association Finance, Tax, and Buyers seminar. “People are suspicious but there really are no hooks with community solar.”

LMI residents are leery to provide tax records or much documents at all in order to sign up for community solar, LaMora said. “We were surprised to see less of a default rate with LMI residents. We attribute this to the fact that they see significant savings on their electric bill, making it easier to pay each month,” he said.

Data Show Clean Power Increasing, Fossil Fuel Decreasing in California

California clean electricity accelerates with renewables as solar and wind surge, battery storage strengthens grid resilience, natural gas declines, and coal fades, advancing SB 100 targets, carbon neutrality goals, and affordable, reliable power statewide.

 

Key Points

California clean electricity is the state's transition to renewable, zero-carbon power, scaling solar, wind and storage.

✅ Solar generation up nearly 20x since 2012

✅ Natural gas power down 20%; coal nearly phased out

✅ Battery storage shifts daytime surplus to evening demand

 

Data from the California Energy Commission (CEC) highlight California’s continued progress toward building a more resilient grid, achieving 100 percent clean electricity and meeting the state’s carbon neutrality goals.

Analysis of the state’s Total System Electric Generation report shows how California’s power mix has changed over the last decade. Since 2012:

Solar generation increased nearly twentyfold from 2,609 gigawatt-hours (GWh) to 48,950 GWh.

  • Wind generation grew by 63 percent.
  • Natural gas generation decreased 20 percent.
  • Coal has been nearly phased-out of the power mix, and renewable electricity surpassed coal nationally in 2022 as well.

In addition to total utility generation, rooftop solar increased by 10 times generating 24,309 GWh of clean power in 2022. The state’s expanding fleet of battery storage resources also help support the grid by charging during the day using excess renewable power for use in the evening.

“This latest report card showing how solar energy boomed as natural gas powered electricity experienced a steady 20 percent decline over the last decade is encouraging,” said CEC Vice Chair Siva Gunda. “Even as climate impacts become increasingly severe, California remains committed to transitioning away from polluting fossil fuels and delivering on the promise to build a future power grid that is clean, reliable and affordable.”

Senate Bill 100 (2018) requires 100 percent of California’s electric retail sales be supplied by renewable and zero-carbon energy sources by 2045. To keep the state on track, last year Governor Gavin Newsom signed SB 1020, establishing interim targets of 90 percent clean electricity by 2035 and 95 percent by 2040.

The state monitors progress through the Renewables Portfolio Standard (RPS), which tracks the power mix of retail sales, and regional peers such as Nevada's RPS progress offer useful comparison. The latest data show that in 2021 more than 37 percent of the state’s electricity came from RPS-eligible sources such as solar and wind, an increase of 2.7 percent compared to 2020. When combined with other sources of zero-carbon energy such as large hydroelectric generation and nuclear, nearly 59 percent of the state’s retail electricity sales came from nonfossil fuel sources.

The total system electric generation report is based on electric generation from all in-state power plants rated 1 megawatt (MW) or larger and imported utility-scale power generation. It reflects the percentage of a specific resource compared to all power generation, not just retail sales. The total system electric generation report accounts for energy used for water conveyance and pumping, transmission and distribution losses and other uses not captured under RPS.

Wind and Solar Energy Surpass Coal in U.S. Electricity Generation

Wind and Solar Surpass Coal in U.S. power generation, as EIA data cites falling LCOE, clean energy incentives, grid upgrades, and battery storage driving renewables growth, lower emissions, jobs, and less fossil fuel reliance.

 

Key Points

An EIA-noted milestone where U.S. renewables outproduce coal, driven by lower LCOE, policy credits, and grid upgrades.

✅ EIA data shows wind and solar exceed coal generation

✅ Falling LCOE boosts project viability across the grid

✅ Policies and storage advances strengthen reliability

 

In a landmark shift for the energy sector, wind and solar power have recently surpassed coal in electricity generation in the United States. This milestone, reported by Warp News, marks a significant turning point in the country’s energy landscape and underscores the growing dominance of renewable energy sources.

A Landmark Achievement

The achievement of wind and solar energy generating more electricity than coal is a landmark moment in the U.S. energy sector. Historically, coal has been a cornerstone of electricity production, providing a substantial portion of the nation's power needs. However, recent data reveals a transformative shift, with renewables surpassing coal for the first time in 130 years, as renewable energy sources, particularly wind and solar, have begun to outpace coal in terms of electricity generation.

The U.S. Energy Information Administration (EIA) reported that in recent months, wind and solar combined produced more electricity than coal, including a record 28% share in April, reflecting a broader trend towards cleaner energy sources. This development is driven by several factors, including advancements in renewable technology, decreasing costs, and a growing commitment to reducing greenhouse gas emissions.

Technological Advancements and Cost Reductions

One of the key drivers behind this shift is the rapid advancement in wind and solar technologies, as wind power surges in the U.S. electricity mix across regions. Improvements in turbine and panel efficiency have significantly increased the amount of electricity that can be generated from these sources. Additionally, technological innovations have led to lower production costs, making wind and solar energy more competitive with traditional fossil fuels.

The cost of solar panels and wind turbines has decreased dramatically over the past decade, making renewable energy projects more economically viable. According to Warp News, the levelized cost of electricity (LCOE) from solar and wind has fallen to levels that are now comparable to or lower than coal-fired power. This trend has been pivotal in accelerating the transition to renewable energy sources.

Policy Support and Investment

Government policies and incentives have also played a crucial role in supporting the growth of wind and solar energy, with wind now the most-used renewable electricity source in the U.S. helping drive deployment. Federal and state-level initiatives, such as tax credits, subsidies, and renewable energy mandates, have encouraged investment in clean energy technologies. These policies have provided the financial and regulatory support necessary for the expansion of renewable energy infrastructure.

The Biden administration’s focus on addressing climate change and promoting clean energy has further bolstered the transition. The Infrastructure Investment and Jobs Act and the Inflation Reduction Act, among other legislative efforts, have allocated significant funding for renewable energy projects, grid modernization, and research into advanced technologies.

Environmental and Economic Implications

The surpassing of coal by wind and solar energy has significant environmental and economic implications, building on the milestone when renewables became the second-most prevalent U.S. electricity source in 2020 and set the stage for further gains. Environmentally, it represents a major step forward in reducing carbon emissions and mitigating climate change. Coal-fired power plants are among the largest sources of greenhouse gases, and transitioning to cleaner energy sources is essential for meeting climate targets and improving air quality.

Economically, the shift towards wind and solar energy is creating new opportunities and industries. The growth of the renewable energy sector is generating jobs in manufacturing, installation, and maintenance. Additionally, the decreased reliance on imported fossil fuels enhances energy security and stabilizes energy prices.

Challenges and Future Outlook

Despite the progress, there are still challenges to address. The intermittency of wind and solar power requires advancements in energy storage and grid management to ensure a reliable electricity supply. Investments in battery storage technologies and smart grid infrastructure are crucial for overcoming these challenges and integrating higher shares of renewable energy into the grid.

Looking ahead, the trend towards renewable energy is expected to continue, with renewables projected to soon provide about one-fourth of U.S. electricity as deployment accelerates, driven by ongoing technological advancements, supportive policies, and a growing commitment to sustainability. As wind and solar power become increasingly cost-competitive and efficient, their role in the U.S. energy mix will likely expand, further displacing coal and other fossil fuels.

Conclusion

The surpassing of coal by wind and solar energy in U.S. electricity generation is a significant milestone in the transition to a cleaner, more sustainable energy future. This achievement highlights the growing importance of renewable energy sources and the success of technological advancements and supportive policies in driving this transition. As the U.S. continues to invest in and develop renewable energy infrastructure, the move away from coal represents a crucial step towards achieving environmental goals and fostering economic growth in the clean energy sector.

Europe Is Losing Nuclear Power Just When It Really Needs Energy

Europe's Nuclear Energy Policy shapes responses to the energy crisis, soaring gas prices, EU taxonomy rules, net-zero goals, renewables integration, baseload security, SMRs, and Russia-Ukraine geopolitics, exposing cultural, financial, and environmental divides.

 

Key Points

A policy guiding nuclear exits or expansion to balance energy security, net-zero goals, costs, and EU taxonomy.

✅ Divergent national stances: phase-outs vs. new builds

✅ Costs, delays, and waste challenge large reactors

✅ SMRs, renewables, and gas shape net-zero pathways

 

As the Fukushima disaster unfolded in Japan in 2011, then-German Chancellor Angela Merkel made a dramatic decision that delighted her country’s anti-nuclear movement: all reactors would be ditched.

What couldn’t have been predicted was that Europe would find itself mired in one of the worst energy crises in its history. A decade later, the continent’s biggest economy has shut down almost all its capacity already. The rest will be switched off at the end of 2022 — at the worst possible time.

Wholesale power prices are more than four times what they were at the start of the coronavirus pandemic. Governments are having to take emergency action to support domestic and industrial consumers faced with crippling bills, which could rise higher if the tension over Ukraine escalates. The crunch has not only exposed Europe’s supply vulnerabilities, but also the entrenched cultural and political divisions over the nuclear industry and a failure to forge a collective vision. 

Other regions meanwhile are cracking on, challenging the idea that nuclear power is in decline worldwide. China is moving fast on nuclear to try to clean up its air quality. Its suite of reactors is on track to surpass that of the U.S., the world’s largest, by as soon as the middle of this decade. Russia is moving forward with new stations at home and has more than 20 reactors confirmed or planned for export construction, according to the World Nuclear Association.

“I don’t think we’re ever going to see consensus across Europe with regards to the continued running of existing assets, let alone the construction of new ones,” said Peter Osbaldstone, research director for power and renewables at Wood Mackenzie Group Ltd. in the U.K. “It’s such a massive polarizer of opinions that national energy policy is required in strength over a sustained period to support new nuclear investment.” 

France, Europe’s most prolific nuclear energy producer, is promising an atomic renaissance as its output becomes less reliable. Britain plans to replace aging plants in the quest for cleaner, more reliable energy sources. The Netherlands wants to add more capacity, Poland also is seeking to join the nuclear club, and Finland is starting to produce electricity later this month from its first new plant in four decades. 

Belgium and Spain, meanwhile, are following Germany’s lead in abandoning nuclear, albeit on different timeframes. Austria rejected it in a referendum in 1978.

Nuclear power is seen by its proponents as vital to reaching net-zero targets worldwide. Once built, reactors supply low-carbon electricity all the time, unlike intermittent wind or solar.

Plants, though, take a decade or more to construct at best and the risk is high of running over time and over budget. Finland’s new Olkiluoto-3 unit is coming on line after a 12-year delay and billions of euros in financial overruns. 

Then there’s the waste, which stays hazardous for 100,000 years. For those reasons European Union members are still quarreling over whether nuclear even counts as sustainable.

Electorates are also split. Polling by YouGov Plc published in December found that Danes, Germans and Italians were far more nuclear-skeptic than the French, British or Spanish. 

“It comes down to politics,” said Vince Zabielski, partner at New York-based law firm Pillsbury Winthrop Shaw Pittman LLP, who was a nuclear engineer for 15 years. “Everything political ebbs and flows, but when the lights start going off people have a completely different perspective.”

 

What’s Behind Europe’s Skyrocketing Energy Prices

Indeed, there’s a risk of rolling blackouts this winter. Supply concerns plaguing Europe have sent gas and electricity prices to record levels and inflation has ballooned. There’s also mounting tension with Russia over a possible invasion of Ukraine, which could lead to disrupted supplies of gas. All this is strengthening the argument that Europe needs to reduce its dependence on international sources of gas.

Europe will need to invest 500 billion euros ($568 billion) in nuclear over the next 30 years to meet growing demand for electricity and achieve its carbon reduction targets, according to Thierry Breton, the EU’s internal market commissioner. His comments come after the bloc unveiled plans last month to allow certain natural gas and nuclear energy projects to be classified as sustainable investments. 

“Nuclear power is a very long-term investment and investors need some kind of guarantee that it will generate a payoff,” said Elina Brutschin at the International Institute for Applied Systems Analysis. In order to survive in liberalized economies like the EU, the technology needs policy support to help protect investors, she said.

That already looks like a tall order. The European Commission has been told by a key expert group that the labeling risks raising greenhouse gas emissions and undermining the bloc’s reputation as a bastion for environmentally friendly finance.

Austria has threatened to sue the European Commission over attempts to label atomic energy as green. The nation previously attempted a legal challenge, when the U.K. was still an EU member, to stop the construction of Electricite de France SA’s Hinkley Point C plant, in the west of England. It has also commenced litigation against new Russia-backed projects in neighboring Hungary.

Germany, which has missed its carbon emissions targets for the past two years, has been criticized by some environmentalists and climate scientists for shutting down a supply of clean power at the worst time, despite arguments for a nuclear option for climate policy. Its final three reactors will be halted this year. Yet that was never going to be reversed with the Greens part of the new coalition government. 

The contribution of renewables in Germany has almost tripled since the year before Fukushima, and was 42% of supply last year. That’s a drop from 46% from the year before and means the country’s new government will have to install some 3 gigawatts of renewables — equivalent to the generating capacity of three nuclear reactors — every year this decade to hit the country's 80% goal.

“Other countries don’t have this strong political background that goes back to three decades of anti-nuclear protests,” said Manuel Koehler, managing director of Aurora Energy Research Ltd., a company analyzing power markets and founded by Oxford University academics. 

At the heart of the issue is that countries with a history of nuclear weapons will be more likely to use the fuel for power generation. They will also have built an industry and jobs in civil engineering around that.

Germany’s Greens grew out of anti-nuclear protest movements against the stationing of U.S. nuclear missiles in West Germany. The 1986 Chernobyl meltdown, which sent plumes of radioactive fallout wafting over parts of western Europe, helped galvanize the broader population. Nuclear phase-out plans were originally laid out in 2002, but were put on hold by the country's conservative governments. The 2011 Fukushima meltdowns reinvigorated public debate, ultimately prompting Merkel to implement them.

It’s not easy to undo that commitment, said Mark Hibbs, a Bonn, Germany-based nuclear analyst at Carnegie Endowment for International Peace, or to envision any resurgence of nuclear in Germany soon: “These are strategic decisions, that have been taken long in advance.”

In France, President Emmanuel Macron is about to embark on a renewed embrace of nuclear power, even as a Franco-German nuclear dispute complicates the debate. The nation produces about two-thirds of its power from reactors and is the biggest exporter of electricity in Europe. Notably, that includes anti-nuclear Germany and Austria.

EDF, the world’s biggest nuclear plant operator, is urging the French government to support construction of six new large-scale reactors at an estimated cost of about 50 billion euros. The first of them would start generating in 2035.

But even France has faced setbacks. Development of new projects has been put on hold after years of technical issues at the Flamanville-3 project in Normandy. The plant is now scheduled to be completed next year. 

In the U.K., Business Secretary Kwasi Kwarteng said that the global gas price crisis underscores the need for more home-generated clean power. By 2024, five of Britain’s eight plants will be shuttered because they are too old. Hinkley Point C is due to be finished in 2026 and the government will make a final decision on another station before an election due in 2024. 

One solution is to build small modular reactors, or SMRs, which are quicker to construct and cheaper. The U.S. is at the forefront of efforts to design smaller nuclear systems with plans also underway in the U.K. and France. Yet they too have faced delays. SMR designs have existed for decades though face the same challenging economic metrics and safety and security regulations of big plants.

The trouble, as ever, is time. “Any investment decisions you make now aren’t going to come to fruition until the 2030s,” said Osbaldstone, the research director at Wood Mackenzie. “Nuclear isn’t an answer to the current energy crisis.”

Competition in Electricity Has Been Good for Consumers and Good for the Environment

Electricity Market Competition drives lower wholesale prices, stable retail rates, better grid reliability, and faster emissions cuts as deregulation and renewables adoption pressure utilities, improve efficiency, and enhance consumer choice in power markets.

 

Key Points

Electricity market competition opens supply to rivals, lowering prices, improving reliability, and reducing emissions.

✅ Wholesale prices fell faster in competitive markets

✅ Retail rates rose less than in monopoly states

✅ Fewer outages, shorter durations, improved reliability

 

By Bernard L. Weinstein

Electricity used to be boring.  Public utilities that provided power to homes and businesses were regulated monopolies and, by law, guaranteed a fixed rate-of-return on their generation, transmission, and distribution assets. Prices per kilowatt-hour were set by utility commissions after lengthy testimony from power companies, wanting higher rates, and consumer groups, wanting lower rates.

About 25 years ago, the electricity landscape started to change as economists and others argued that competition could lead to lower prices and stronger grid reliability. Opponents of competition argued that consumers weren’t knowledgeable enough about power markets to make intelligent choices in a competitive pricing environment. Nonetheless, today 20 states have total or partial competition for electricity, allowing independent power generators to compete in wholesale markets and retail electric providers (REPs) to compete for end-use customers, a dynamic echoed by the Alberta electricity market across North America. (Transmission, in all states, remains a regulated natural monopoly).

A recent study by the non-partisan Pacific Research Institute (PRI) provides compelling evidence that competition in power markets has been a boon for consumers. Using data from the U.S. Energy Information Administration (EIA), PRI’s researchers found that wholesale electricity prices in competitive markets have been generally declining or flat, prompting discussions of free electricity business models, over the last five years. For example, compared to 2015, wholesale power prices in New England have dropped more than 44 percent, those in most Mid-Atlantic States have fallen nearly 42 percent, and in New York City they’ve declined by nearly 45 percent. Wholesale power costs have also declined in monopoly states, but at a considerably slower rate.

As for end-users, states that have competitive retail electricity markets have seen smaller price increases, as consumers can shop for electricity in Texas more cheaply than in monopoly states. Again, using EIA data, PRI found that in 14 competitive jurisdictions, retail prices essentially remained flat between 2008 and 2020. By contrast, retail prices jumped an average of 21 percent in monopoly states.  The ten states with the largest retail price increases were all monopoly-based frameworks. A 2017 report from the Retail Energy Supply Association found customers in states that still have monopoly utilities saw their average energy prices increase nearly 19 percent from 2008 to 2017 while prices fell 7 percent in competitive markets over the same period.

The PRI study also observed that competition has improved grid reliability, the recent power disruptions in California and Texas, alongside disruptions in coal and nuclear sectors across the U.S., notwithstanding. Looking at two common measures of grid resiliency, PRI’s analysis found that power interruptions were 10.4 percent lower in competitive states while the duration of outages was 6.5 percent lower.

Citing data from the EIA between 2008 and 2018, PRI reports that greenhouse gas emissions in competitive states declined on average 12.1 percent compared to 7.3 percent in monopoly states. This result is not surprising, and debates over whether Israeli power supply competition can bring cheaper electricity mirror these dynamics.  In a competitive wholesale market, independent power producers have an incentive to seek out lower-cost options, including subsidized renewables like wind and solar. By contrast, generators in monopoly markets have no such incentive as they can pass on higher costs to end-users. Perhaps the most telling case is in the monopoly state of Georgia where the cost to build nuclear Plant Vogtle has doubled from its original estimate of $14 billion 12 years ago. Overruns are estimated to cost Georgia ratepayers an average of $854, and there is no definite date for this facility to come on line. This type of mismanagement doesn’t occur in competitive markets.

Unfortunately, some critics are attempting to halt the momentum for electricity competition and have pointed to last winter’s “deep freeze” in Texas that left several million customers without power for up to a week. But this example is misplaced. Power outages in February were the result of unprecedented and severe weather conditions affecting electricity generation and fuel supply, and numerous proposals to improve Texas grid reliability have focused on weatherization and fuel resilience; the state simply did not have enough access to natural gas and wind generation to meet demand. Competitive power markets were not a factor.

The benefits of wholesale and retail competition in power markets are incontrovertible. Evidence shows that households and businesses in competitive states are paying less for electricity while grid reliability has improved. The facts also suggest that wholesale and retail competition can lead to faster reductions in greenhouse gas emissions. In short, competition in power markets is good for consumers and good for the environment.
