2020 U.S. Renewable Electricity Generation set a record as wind, solar, hydro, biomass, and geothermal produced 834 billion kWh, surpassing coal and nuclear, second only to natural gas in nationwide power output.

 

Key Points

The record year when renewables made 834 billion kWh, topping coal and nuclear in U.S. electricity.

✅ Renewables supplied 21% of U.S. electricity in 2020

✅ Coal output fell 20% y/y; nuclear slipped 2% on retirements

✅ EIA forecasts renewables rise in 2021-2022; coal rebounds

 

In 2020, renewable energy sources (including wind, hydroelectric, solar, biomass, and geothermal energy) generated a record 834 billion kilowatthours (kWh) of electricity, or about 21% of all the electricity generated in the United States. Only natural gas (1,617 billion kWh) produced more electricity than renewables in the United States in 2020. Renewables surpassed both nuclear (790 billion kWh) and coal (774 billion kWh) for the first time on record. This outcome in 2020 was due mostly to significantly less coal use in U.S. electricity generation and steadily increased use of wind and solar generation over time, amid declining consumption trends nationwide.

In 2020, U.S. electricity generation from coal in all sectors declined 20% from 2019, while renewables, including small-scale solar, increased 9%. Wind, currently the most prevalent source of renewable electricity in the United States, grew 14% in 2020 from 2019, and the EIA expects solar and wind to be larger sources in summer 2022, reflecting continued growth. Utility-scale solar generation (from projects greater than 1 megawatt) increased 26%, and small-scale solar, such as grid-connected rooftop solar panels, increased 19%, while early 2021 January power generation jumped year over year.

Coal-fired electricity generation in the United States peaked at 2,016 billion kWh in 2007 and much of that capacity has been replaced by or converted to natural gas-fired generation since then. Coal was the largest source of electricity in the United States until 2016, and 2020 was the first year that more electricity was generated by renewables and by nuclear power than by coal (according to our data series that dates back to 1949). Nuclear electric power declined 2% from 2019 to 2020 because several nuclear power plants retired and other nuclear plants experienced slightly more maintenance-related outages.

We expect coal-fired generation to increase in the United States during 2021 as natural gas prices continue to rise and as coal becomes more economically competitive. Based on forecasts in our Short-Term Energy Outlook (STEO), we expect coal-fired electricity generation in all sectors in 2021 to increase 18% from 2020 levels before falling 2% in 2022. We expect U.S. renewable generation across all sectors to increase 7% in 2021 and 10% in 2022, and in 2021, non-fossil fuel sources accounted for about 40% of U.S. electricity. As a result, we forecast coal will be the second-most prevalent electricity source in 2021, and renewables will be the second-most prevalent source in 2022. We expect nuclear electric power to decline 2% in 2021 and 3% in 2022 as operators retire several generators.

Fact check: Claim on electric car charging efficiency gets some math wrong

EV Charging Coal and Oil Claim: Fact-check of kWh, CO2 emissions, and electricity grid mix shows 70 lb coal or ~8 gallons oil per 66 kWh, with renewables and natural gas reducing lifecycle emissions.

 

Key Points

A viral claim on EV charging overstates oil use; accurate figures depend on grid mix: ~70 lb coal or ~8 gallons oil.

✅ About 70 lb coal or ~8 gal oil per 66 kWh, incl. conversion losses

✅ EVs average ~100 g CO2 per mile vs ~280 g for 30 mpg cars

✅ Grid mix includes renewables, nuclear, natural gas; oil use is low

 

The claim: Average electric car requires equivalent of 85 pounds of coal or six barrels of oil for a single charge

The Biden administration has pledged to work towards decarbonizing the U.S. electricity grid by 2035. And the recently passed $1.2 trillion infrastructure bill provides funding for more electric vehicle (EV) charging infrastructure, including EV charging networks across the country under current plans.

However, a claim that electric cars require an inordinate amount of oil or coal energy to charge has appeared on social media, even as U.S. plug-ins traveled 19 billion miles on electricity in 2021.

“An average electric car takes 66 KWH To charge. It takes 85 pounds of coal or six barrels of oil to make 66 KWH,” read a Dec 1 Facebook post that was shared nearly 500 times in a week. “Makes absolutely no sense.” 

The post included a stock image of an electric car charging, though actual charging costs depend on local rates and vehicle efficiency.

This claim is in the ballpark for the coal comparison, but the math on the oil usage is wildly inaccurate.

It would take roughly 70 pounds of coal to produce the energy required to charge a 66 kWh electric car battery, said Ian Miller, a research associate at the MIT Energy Initiative. That's about 15 pounds less than is claimed in the post.

The oil number is much farther off.

While the post claims that it takes six barrels of oil to charge a 66 kWh battery, Miller said the amount is closer to 8 gallons  — the equivalent of 20% of one barrel of oil.

He said both of his estimates account for energy lost when fossil fuels are converted into electricity. 

"I think the most important question is, 'How do EVs and gas cars compare on emissions per distance?'," said Miller. "In the US, using average electricity, EVs produce roughly 100 grams of CO2 per mile."

He said this is more than 60% less than a typical gasoline-powered car that gets 30 mpg, aligning with analyses that EVs are greener in all 50 states today according to recent studies. Such a vehicle produces roughly 280 grams of CO2 per mile.

Lifecycle analyses also show that the CO2 from making an EV battery is not equivalent to driving a gasoline car for years, which often counters common misconceptions.

"If you switch to an electric vehicle, even if you're using fossil fuels (to charge), it's just simply not true that you'll be using more fossil fuel," said Jessika Trancik, a professor at the Massachusetts Institute of Technology who studies the environmental impact of energy systems.  

However, she emphasized electric cars in the U.S. are not typically charged using only energy from coal or oil, and that electricity grids can handle EVs with proper management.

The U.S. electricity grid relies on a diversity of energy sources, of which oil and coal together make up about 20 percent, according to a DOE spokesperson. This amount is likely to continue to drop as renewable energy proliferates in the U.S., even as some warn that state power grids will be challenged by rapid EV adoption. 

"Switching to an electric vehicle means that you can use other sources, including less carbon-intensive natural gas, and even less carbon-intensive electricity sources like nuclear, solar and wind energy, which also carry with them health benefits in the form of reduced air pollutant emissions," said Trancik. 

Our rating: Partly false
Based on our research, we rate PARTLY FALSE the claim that the average electric car requires the equivalent of 85 pounds of coal or six barrels of oil for a single charge. The claim is in the ballpark on coal consumption, as an MIT researcher estimates that around 70 pounds. But the oil usage is only about 8 gallons, which is 20% of one barrel. And the actual sources of energy for an electric car vary depending on the energy mix in the local electric grid.

Spread of Electric Cars Sparks Fights for Control Over Charging

Utility-Controlled EV Charging shapes who builds charging stations as utilities, regulators, and private networks compete over infrastructure, grid upgrades, and pricing, impacting ratepayers, competition, and EV adoption across states seeking cleaner transport.

 

Key Points

Utility-controlled EV charging is utilities building charging networks affecting rates, competition and grid costs.

✅ Regulated investment may raise rates before broader savings.

✅ Private firms warn monopolies stifle competition and innovation.

✅ Regulators balance access, equity, and grid upgrade needs.

 

Electric vehicles are widely seen as the automobile industry’s future, but a battle is unfolding in states across America over who should control the charging stations that could gradually replace fuel pumps.

From Exelon Corp. to Southern California Edison, utilities have sought regulatory approval to invest millions of dollars in upgrading their infrastructure as state power grids adapt to increased charging demand, and, in some cases, to own and operate chargers.

The proposals are sparking concerns from consumer advocates about higher electric rates and oil companies about subsidizing rivals. They are also drawing opposition from startups that say the successors to gas stations should be open to private-sector competition, not controlled by monopoly utilities.

That debate is playing out in regulatory commissions throughout the U.S. as states and utilities promote wider adoption of electric vehicles. At stake are charging infrastructure investments expected to total more than $13 billion over the next five years, as an American EV boom accelerates, according to energy consulting firm Wood Mackenzie. That would cover roughly 3.2 million charging outlets.

Calvin Butler Jr., who leads Exelon’s utilities business, said many states have grown more open to the idea of utilities becoming bigger players in charging as electric vehicles have struggled to take off in the U.S., where they make up only around 2% of new car sales.

“When the utilities are engaged, there’s quicker adoption because the infrastructure is there,” he said.

Major auto makers including General Motors Co. and Ford Motor Co. are accelerating production of electric vehicles, and models like Tesla’s Model 3 are shaping utility planning, and a number of states have set ambitious EV goals—most recently California, which aims to ban the sale of new gasoline-powered cars by 2035. But a patchy charging-station network remains a huge impediment to mass EV adoption.

Democratic presidential candidate Joe Biden has called for building more than 500,000 new public charging outlets in a decade as part of his plan to combat climate change, amid Biden’s push to electrify the transportation sector. But exactly how that would happen is unclear. The U.S. currently has fewer than 100,000 public outlets, according to the Energy Department. President Trump, who has weakened federal tailpipe emissions targets, hasn’t put forward an electric-vehicle charging plan, though he backed a 2019 transportation bill that would have provided $1 billion in grants to build alternative fueling infrastructure, including for electric vehicles.

Charging access currently varies widely by state, as does utility involvement, with many utilities bullish course on EV charging to support growth, which can range from providing rebates on home chargers to preparing sites for public charging—and even owning and operating the equipment needed to juice up electric vehicles.

As of September, regulators in 24 states had signed off on roughly $2.6 billion of utility investment in transportation electrification, according to Atlas Public Policy, a Washington, D.C., policy firm. More than half of that spending was authorized in California, where electric vehicle adoption is highest.

Nearly a decade ago, California blocked utilities from owning most charging equipment, citing concerns about potentially stifling competition. But the nation’s most populous state reversed course in 2014, seeking to spur electrification.

Regulators across the country have since been wrestling with similar questions, generating a patchwork of rules.

Maryland regulators signed off last year on a pilot program allowing subsidiaries of Exelon and FirstEnergy Corp. to own and operate public charging stations on government property, provided that the drivers who use them cover at least some of the costs.

Months later, the District of Columbia rejected an Exelon subsidiary’s request to own public chargers, saying independent charging companies had it covered.

Some charging firms argue utilities shouldn’t be given monopolies on car charging, though they might need to play a role in connecting rural customers and building stations where they would otherwise be uneconomical.

“Maybe the utility should be the supplier of last resort,” said Cathy Zoi, chief executive of charging network EVgo Services LLC, which operates more than 800 charging stations in 34 states.

Utility charging investments generally are expected to raise customers’ electricity bills, at least initially. California recently approved the largest charging program by a single utility to date: a $436 million initiative by Southern California Edison, an arm of Edison International, as the state also explores grid stability opportunities from EVs. The company said it expects the program to increase the average residential customer’s bill by around 50 cents a month.

But utilities and other advocates of electrification point to studies indicating greater EV adoption could help reduce electricity rates over time, by giving utilities more revenue to help cover system upgrades.

Proponents of having utilities build charging networks also argue that they have the scale to do so more quickly, which would lead to faster EV adoption and environmental improvements such as lower greenhouse gas emissions and cleaner air. While the investments most directly help EV owners, “they accrue immediate benefits for everyone,” said Jill Anderson, a Southern California Edison senior vice president.

Some consumer advocates are wary of approving extensive utility investment in charging, citing the cost to ratepayers.

“It’s like, ‘Pay me now, and maybe someday your rates will be less,’” said Stefanie Brand, who advocates on behalf of ratepayers for the state of New Jersey, where regulators have yet to sign off on any utility proposals to invest in electric vehicle charging. “I don’t think it makes sense to build it hoping that they will come.”

Groups representing oil-and-gas companies, which stand to lose market share as people embrace electric vehicles, also have criticized utility charging proposals.

“These utilities should not be able to use their monopoly power to use all of their customers’ resources to build investments that definitely won’t benefit everybody, and may or may not be economical at this point,” said Derrick Morgan, who leads federal and regulatory affairs at the American Fuel & Petrochemical Manufacturers, a trade organization.

Utility executives said their companies have long been used to further government policy objectives deemed to be in the public interest, drawing on lessons from 2021 to guide next steps, such as improving energy efficiency.

“This isn’t just about letting market forces work,” said Mike Calviou, senior vice president for strategy and regulation at National Grid PLC’s U.S. division.

Nevada to Power Clean Vehicles with Clean Electricity

Nevada EV Charging Plan will invest $100 million in highway, urban, and public charging, bus depots, and Lake Tahoe sites, advancing NV Energy's SB 448 goals for clean energy, air quality, equity, and tourism recovery.

 

Key Points

Program invests $100M in EV infrastructure under SB 448, led by NV Energy, expanding clean charging across Nevada.

✅ $100M for statewide charging over 3 years

✅ 50% invested in overburdened communities

✅ Supports SB 448, climate and air quality goals

 

The Public Utilities Commission of Nevada approved a $100 million program that will deploy charging stations for electric vehicles (EVs) along highways, in urban areas, at public buildings, in school and transit bus depots, and at Red Rocks and Lake Tahoe, as charging networks compete to expand access. Combined with the state's clean vehicle standards and its aggressive renewable energy requirements, this means cars, trucks, buses, and boats in Nevada will be powered by increasingly clean electricity, reflecting how electricity is changing across the country.

The “Economic Recovery Transportation Electrification Plan” proposed by NV Energy, aligning with utilities' bullish plans for EV charging, was required by Senate Bill (SB) 448 (Brooks). Nevada’s tourism-centric economy was hit hard by the pandemic, and, as an American EV boom accelerates nationwide, the $100 million investment in charging infrastructure for light, medium, and heavy-duty EVs over the next three years was designed to provide much needed economic stimulus without straining the state’s budget.

Half of those investments will be made in communities that have borne a disproportionate share of transportation pollution and have suffered most from COVID-19—a disease that is made more deadly by exposure to local air pollution—and, amid evolving state grid challenges that planners are addressing, ensuring equitable deployment will help protect reliability and health.

SB 448 also requires NV Energy to propose subsequent “Transportation Electrification Plans” to keep the state on track to meet its climate, air quality, and equity goals, recognizing that a much bigger grid may be needed as adoption grows. A  report from MJ Bradley & Associates commissioned by NRDC, Southwest Energy Efficiency Project, and Western Resource Advocates demonstrates Nevada could realize $21 billion in avoided expenditures on gasoline and maintenance, reduced utility bills, and environmental benefits, with parallels to New Mexico's projected benefits highlighted in recent analyses, by 2050 if more drivers make the switch to EVs.

New legislation will make it easier for strata owners to install EV charging stations

BC Strata EV Charging Reforms streamline approvals under the Strata Property Act, lowering the voting threshold and requiring an electrical planning report to expand EV charging stations in multi-unit strata buildings across British Columbia.

 

Key Points

BC reforms ease EV charger installs in stratas by lowering votes, requiring plans, and fast-tracking compliant requests.

✅ Vote threshold drops to 50% for EV infrastructure

✅ Electrical planning report required for stratas

✅ Stratas must approve compliant owner charging requests

 

Owning an electric vehicle (EV) will be a little easier for strata property owners, the province says, after announcing changes to legislation to facilitate the installation of charging stations in strata buildings.

On Thursday, the province said it would be making amendments to the Strata Property Act, the legal framework all strata corporations are required to follow, and align with practical steps for retrofitting condos with chargers in older buildings.

Three areas will improve access to EV charging stations in strata complexes, the province says, including lowering the voting threshold from 75 per cent to 50 per cent for approval of the costs, supported by EV charger rebates that can offset expenses, and changes to the property that are needed to install them, as well as requiring strata corporations to have an electrical planning report to make installation of these stations easier.

The amendments would mean stratas would have to approve owners' requests for such charging stations, even amid high-rise EV charging challenges reported across Canada, as long as "reasonable criteria are met."

Minister of Energy, Mines and Low Carbon Innovation Josie Osborne said people are more likely to buy an electric vehicle if they have the ability to charge it — something that's lacking for many British Columbians living in multi-unit residences, where Vancouver's EV-ready policy is setting a local example for multi-family buildings. 

"B.C. has one of the largest public electric vehicle charging networks in Canada, and leads the country in going electric, but we need to make it easier for more people to charge their EVs at home," Osborne said in a statement.

Tony Gioventu, the executive director of the Condominium Home Owners Association of B.C., said the new legislation strikes a balance between allowing people access to EV charging stations, as examples from Calgary apartments and condos demonstrate, while also ensuring stratas still have control over their properties. 

This is just the latest step in the B.C. government's move to get more EVs on the road: alongside rebates for home and workplace charging, the province passed the Zero-Emission Vehicles Act, which aims for 10 per cent of all new light-duty cars and trucks sold in B.C. to be zero emission by 2025. By 2040, they'll all need to be emission-free.

NREL’s Electric Vehicle Infrastructure Projection Tool Helps Utilities, Agencies, and Researchers Predict Hour-by-Hour Impact of Charging on the Grid

EVI-Pro Lite EV Load Forecasting helps utilities model EV charging infrastructure, grid load shapes, and resilient energy systems, factoring home, workplace, and public charging behavior to inform planning, capacity upgrades, and flexible demand strategies.

 

Key Points

A NREL tool projecting EV charging demand and load shapes to help utilities plan the grid and right-size infrastructure.

✅ Visualizes weekday/weekend EV load by charger type.

✅ Tests home, workplace, and public charging access scenarios.

✅ Supports utility planning, demand flexibility, and capacity upgrades.

 

As electric vehicles (EVs) continue to grow in popularity, utilities and community planners are increasingly focused on building resilient energy systems that can support the added electric load from EV charging, including a possible EV-driven demand increase across the grid.

But forecasting the best ways to adapt to increased EV charging can be a difficult task as EV adoption will challenge state power grids in diverse ways. Planners need to consider when consumers charge, how fast they charge, and where they charge, among other factors.

To support that effort, researchers at the National Renewable Energy Laboratory (NREL) have expanded the Electric Vehicle Infrastructure Projection (EVI-Pro) Lite tool with more analytic capabilities. EVI-Pro Lite is a simplified version of EVI-Pro, the more complex, original version of the tool developed by NREL and the California Energy Commission to inform detailed infrastructure requirements to support a growing EV fleet in California, where EVs bolster grid stability through coordinated planning.

EVI-Pro Lite’s estimated weekday electric load by charger type for El Paso, Texas, assuming a fleet of 10,000 plug-in electric vehicles, an average of 35 daily miles traveled, and 50% access to home charging, among other variables, as well as potential roles for vehicle-to-grid power in future scenarios. The order of the legend items matches the order of the series stacked in the chart.

Previously, the tool was limited to letting users estimate how many chargers and what kind of chargers a city, region, or state may need to support an influx of EVs. In the added online application, those same users can take it a step further to predict how that added EV charging will impact electricity demand, or load shapes, in their area at any given time and inform grid coordination for EV flexibility strategies.

“EV charging is going to look different across the country, depending on the prevalence of EVs, access to home charging, and the kind of chargers most used,” said Eric Wood, an NREL researcher who led model development. “Our expansion gives stakeholders—especially small- to medium-size electric utilities and co-ops—an easy way to analyze key factors for developing a flexible energy strategy that can respond to what’s happening on the ground.”

Tools to forecast EV loads have existed for some time, but Wood said that EVI-Pro Lite appeals to a wider audience, including planners tracking EVs' impact on utilities in many markets. The tool is a user-friendly, free online application that displays a clear graphic of daily projected electric loads from EV charging for regions across the country.

After selecting a U.S. metropolitan area and entering the number of EVs in the light-duty fleet, users can change a range of variables to see how they affect electricity demand on a typical weekday or weekend. Reducing access to home charging by half, for example, results in higher electric loads earlier in the day, although energy storage and mobile charging can help moderate peaks in some cases. That is because under such a scenario, EV owners might rely more on public or workplace charging instead of plugging in at home later in the evening or at night.

“Our goal with the lite version of EVI-Pro is to make estimating loads across thousands of scenarios fast and intuitive,” Wood said. “And if utilities or stakeholders want to take that analysis even deeper, our team at NREL can fill that gap through partnership agreements, too. The full version of EVI-Pro can be tailored to develop detailed studies for individual planners, agencies, or utilities.”

U.S. Electric Vehicle Sales Soar Into 2024

U.S. EV Sales Growth reflects rising consumer demand, expanding market share, new tax credits, and robust charging infrastructure, as automakers boost output and quarterly sales under the Inflation Reduction Act drive adoption across states.

 

Key Points

It is the rise in U.S. EV sales and market share, driven by incentives, charging growth, and automaker investment.

✅ Quarterly EV sales and share have risen since Q3 2021.

✅ Share topped 10% in Q3 2023, with states far above.

✅ IRA credits and chargers lower costs and boost adoption.

 

Contrary to any skepticism, the demand for electric vehicles (EVs) in the United States is not dwindling. Data from the Alliance for Automotive Innovation highlights a significant and ongoing increase in EV sales from 2021 through the third quarter of 2023. An upward trend in quarterly sales (depicted as bars on the left axis) and EV sales shares (illustrated by the red line on the right axis) is evident. Sales surged from about 125,000 in Q1 2021 to 185,000 in Q4 2021, and from around 300,000 in Q1 2023 to 375,000 by Q3 2023. Notably, by Q3 2023, annual U.S. EV sales exceeded 1 million for the first time, a milestone often cited as the tipping point for mass adoption in the U.S., marking a 58% increase over the same period in 2022.

EV sales have shown consistent quarterly growth since Q3 2021, and the proportion of EVs in total light-duty vehicle sales is also on the rise. EVs’ share of new sales increased from roughly 3% in Q1 2021 to about 7% in 2022, and further to over 10% in Q3 2023, though they are still behind gas cars in overall market share, for now. For context, according to the U.S. Environmental Protection Agency’s Automotive Trends Report, EVs have reached a 10% market share more quickly than conventional hybrids without a plug, which took about 25 years.

State-level data also indicates that several states exceed national averages in EV sales. California, for example, saw EVs comprising nearly 27% of sales through September 2023, even as a brief Q1 2024 market share dip has been noted nationally. Additionally, 12 states plus the District of Columbia had EV sales shares between 10% and 20% through Q3 2023.

EV sales data by automaker reveal that most companies sold more EVs in Q2 or Q3 2023 than in any previous quarter, mirroring global growth that went from zero to 2 million in five years. Except for Ford, each automaker sold more EVs in the first three quarters of 2023 than in all of 2022. EV sales in Q3 2023 notably increased compared to Q3 2022 for companies like BMW, Tesla, and Volkswagen.

Despite some production scalebacks by Ford and General Motors, these companies, along with others, remain dedicated to an electric future and expect to sell more EVs than ever. The growing consumer interest in EVs is also reflected in recent surveys by McKinsey, J.D. Power, and Consumer Reports, and echoed in Europe where the share of electric cars grew during lockdown months, showing an increasing intent to purchase EVs and a declining interest in gasoline vehicles.

Furthermore, the Inflation Reduction Act of 2022 introduces new tax credits, potentially making EVs more affordable than gasoline counterparts. Investments in charging infrastructure are also expected to increase, especially as EV adoption could drive a 38% rise in U.S. electricity demand, with over $21 billion allocated to boost public chargers from around 160,000 in 2023 to nearly 1 million by 2030.

The shift to EVs is crucial for reducing climate pollution, enhancing public health, and generating economic benefits and jobs, and by 2021 plug-in vehicles had already traveled 19 billion miles on electricity, underscoring real-world progress toward these goals. The current data and trends indicate a robust and positive future for EVs in the U.S., reinforcing the need for strong standards to further encourage investment and consumer confidence in electric vehicles.
