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electricity generation in the United States peaked at 2,016 billion kWh in 2007 and much of that capacity has been replaced by or converted to natural gas-fired generation since then.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.

Wind and solar power generated more electricity in the EU last year than gas. Here's how

EU Renewable Energy Transition accelerates as solar and wind overtake gas, cutting coal reliance and boosting REPowerEU goals; falling electricity demand, hydro and nuclear recovery, and grid upgrades drive a cleaner, secure power mix.

 

Key Points

It is the EU's shift to solar and wind, surpassing gas and curbing coal to meet REPowerEU targets.

✅ Solar and wind supplied 22% of EU electricity in 2022.

✅ Gas fell behind; coal stayed near 16% with no major rebound.

✅ Demand fell; hydro and nuclear expected to recover in 2023.

 

European countries were forced to accelerate their renewable energy capacity after Russia's invasion of Ukraine sparked a global energy crisis amid a surge in global power demand that exceeded pre-pandemic levels. The EU’s REPowerEU plan aims to increase the share of renewables in final energy consumption overall to 45 percent by the end of the decade.

However, a new report by energy think tank Ember shows that the EU’s green energy transition is already making a significant difference. Solar and wind power generated more than a fifth (22 percent) of its electricity in 2022, pulling ahead of fossil gas (20 percent) for the first time, according to the European Electricity Review 2023.

Europe also managed to avoid resorting to emissions-intensive coal power for electricity generation as a consequence of the energy crisis, even as renewables to eclipse coal globally by mid-decade. Coal generated just 16 percent of the EU’s electricity last year, an increase of just 1.5 percentage points.

“Europe has avoided the worst of the energy crisis,” says Ember’s Head of Data Insights, Dave Jones. “The shocks of 2022 only caused a minor ripple in coal power and a huge wave of support for renewables. Any fears of a coal rebound are now dead.”

Ember’s analysis reveals that the EU faced a "triple crisis" in the electricity sector in 2022, as stunted hydro and nuclear output compounded the shock. "Just as Europe scrambled to cut ties with its biggest supplier of fossil gas, it faced the lowest levels of hydro and nuclear (power) in at least two decades, which created a deficit equal to 7 percent of Europe’s total electricity demand in 2022," the report says. A severe drought across Europe, French nuclear outages as well as the closure of German nuclear outlets were responsible for the drop.

 

Solar power shines through
However, the record surge in solar and wind power generation helped compensate for the nuclear and hydropower deficit. Solar power rose the fastest, growing by a record 24 percent last year which almost doubled its previous record, with wind growing by 8.6 percent.

Forty-one gigawatts of solar power capacity was added in 2022, almost 50 percent more than the year before. Ember says that 20 EU countries achieved solar records in 2022, with Germany, Spain, Poland, the Netherlands and France adding the most solar capacity.

The Netherlands and Greece generated more power from solar than coal for the first time. Greece is also predicted to reach its 2030 solar capacity target by the end of this year.


EU electricity demand falls
A significant drop in electricity use in 2022 also helped lessen the impact of Europe’s energy crisis. Demand fell by 7.9 percent in the last quarter of the year, despite the continent heading into winter. This was close to the 9.6 percent fall experienced when Europe was in Covid-19 lockdown in mid-2020.

"Mild weather was a deciding factor, but affordability pressures likely played a role, alongside energy efficiency improvements and citizens acting in solidarity to cut energy demand in a time of crisis," the report says.

A ‘coal comeback’ fails to materialize
The almost 8 percent fall in electricity demand in the last three months of 2022 was the main factor in the 9 percent fall in gas and coal generation during that time. However, Ember says that had France’s nuclear plants been operating at the same capacity as 2021, the EU’s fossil fuel generation would have fallen twice as fast in the last quarter of 2022.

The report says: "Coal power in the EU fell in all four of the final months of 2022, down 6 percent year-on-year. The 26 coal units placed on emergency standby for winter ran at an average of just 18 percent capacity. Despite importing 22 million tonnes of extra coal throughout 2022, the EU only used a third of it."

Gas generation was very similar compared to 2021, up just 0.8 percent. It made up 20 percent of the EU electricity mix in 2022, up from 19 percent the year before.


Fossil fuel generation set to fall in 2023
Ember says low-emissions sources like solar and wind power will continue to accelerate in 2023 and hydropower and French nuclear capacity will also recover. With electricity demand likely to continue to fall, it estimates that fossil fuel-generation "could plummet" by 20 percent in 2023.

Gas generation will fall the fastest, Ember predicts, as it will remain more expensive than coal over the next few years. "The large fall in gas generation means the power sector is likely to be the fastest falling segment of gas demand during 2023, helping to bring calm to European gas markets as Europe adjusts to life without Russian gas."

In order to stick to the 2015 Paris Agreement target of limiting global warming to no more than 1.5 degrees Celsius compared to pre-industrial levels, Ember says Europe must fully decarbonize its power system by the mid-2030s. Its modeling shows that this is possible without compromising the security of supply.

However, the report says "making this vision a reality will require investment above and beyond existing plans, as well as immediate action to address barriers to the expansion of clean energy infrastructure. Such a mobilization would boost the European economy, cement the EU’s position as a climate leader and send a vital international message that these challenges can be overcome."

Toronto to start trial run of 'driverless' electric vehicle shuttles

Toronto Olli 2.0 Self-Driving Shuttle connects West Rouge to Rouge Hill GO with autonomous micro-transit. Electric shuttle pilot by Local Motors and Pacific Western Transportation, funded by Transport Canada, features accessibility, TTC and Metrolinx support.

 

Key Points

An autonomous micro-transit pilot linking West Rouge to Rouge Hill GO, with accessibility and onboard staff.

✅ Last-mile link: West Rouge to Rouge Hill GO

✅ Accessible: ramp, wheelchair securement, A/V announcements

✅ Operated with attendants; funded by Transport Canada

 

The city of Toronto, which recently opened an EV education centre to support adoption, has approved the use of a small, self-driving electric shuttle vehicle that will connect its West Rouge neighbourhood to the Rouge Hill GO station, a short span of a few kilometres.

It’s called the Olli 2.0, and it’s a micro-shuttle with service provided by Local Motors, in partnership with Pacific Western Transportation, as the province makes it easier to build EV charging stations to support growing demand.

The vehicle is designed to hold only eight people, and has an accessibility ramp, a wheelchair securement system, audio and visual announcements, and other features for providing rider information, aligning with transit safety policies such as the TTC’s winter lithium-ion device restrictions across the system.

“We are continuing to move our city forward on many fronts including micro-transit as we manage the effects of COVID-19,” said Mayor John Tory. “This innovative project will provide valuable insight, while embracing innovation that could help us build a better, more sustainable and equitable transportation network.”

At the provincial level, the public EV charging network has faced delays, underscoring infrastructure challenges.


Although the vehicle is “self-driving,” it will still require two people onboard for every trip during the six- to 12-month trial; those people will be a certified operator from Pacific Western Transportation, and either a TTC ambassador from an agency introducing battery electric buses across its fleet, or a Metrolinx customer service ambassador.

Funding for the program comes from Transport Canada, as part of a ten-year pilot program to test automated vehicles on Ontario’s roads that was approved in 2016, and it complements lessons from the TTC’s largest battery-electric bus fleet as well as emerging vehicle-to-grid programs that engage EV owners.

West Wind Clean Energy Project Launched

Nova Scotia’s West Wind Clean Energy Project aims to harness offshore wind power to deliver renewable electricity, expand transmission infrastructure, and position Canada as a global leader in sustainable energy generation.

 

What is West Wind Clean Energy?

The West Wind Clean Energy Project is Nova Scotia’s $60-billion offshore wind initiative to generate up to 66 GW of clean electricity for Canada’s growing energy needs.

✅ Harnesses offshore wind resources for renewable power generation

✅ Expands grid and transmission infrastructure for clean energy exports

✅ Supports Canada’s transition to a sustainable, low-carbon economy

Nova Scotia has launched one of the most ambitious clean energy projects in Canadian history — a $60-billion plan to build 66 gigawatts (GW) of offshore wind capacity, as countries like the UK expand offshore wind, capable of meeting up to 27 per cent of the nation’s total electricity demand.

Premier Tim Houston unveiled the project, called West Wind, in June, positioning it as a cornerstone of Canada’s broader energy transition and aligning it with Prime Minister Mark Carney’s goal of making the country both a clean energy and conventional energy superpower. Three months later, Carney announced a slate of “nation-building” infrastructure projects the federal government would fast-track. While West Wind was not on the initial list, it was included in a second tier of high-potential proposals still under development.

The plan’s scale is unprecedented for Canada’s offshore energy industry, as organizations like Marine Renewables Canada pivot toward offshore wind to accelerate growth. However, enormous logistical, financial, and market challenges remain. Turbines will not be in the water for years, and the global offshore wind industry itself is facing one of its most difficult periods in over a decade.

“Right now is probably the worst time in 15 years to launch a project like this,” said an executive at a Canadian energy company who requested anonymity. “It’s not Nova Scotia’s fault. It’s just really bad timing.” He pointed to failed offshore wind auctions in Europe, rising costs, and policy reversals in the United States as troubling signals for investors, even as New York’s largest offshore wind project moved ahead this year. “You can’t build the wind and hope the lines come later. You have to build both — together.”

Indeed, transmission infrastructure is emerging as the project’s biggest obstacle. Nova Scotia’s local electricity demand is limited, meaning most of the power would need to be sold to markets in Ontario, Quebec, and New England. Of the $60 billion budgeted for West Wind, $40 billion is allocated to generation, and $20 billion to new transmission — massive sums that require close federal-provincial coordination and long-term investment planning.

Despite the economic headwinds, advocates argue that West Wind could transform Atlantic Canada’s energy landscape and strengthen national energy security, building on recent tidal power investments in Nova Scotia. Peter Nicholson, chair of the Canadian Climate Institute and author of Catching the Wind: How Atlantic Canada Can Become an Energy Superpower, believes the project could redefine Nova Scotia’s role in Canada’s energy transition.

“It’s very well understood where the world is headed,” Nicholson said, noting that wind power is becoming increasingly competitive worldwide. “We’re moving toward an electrical future that’s cleanly generated for economic, environmental, and security reasons. But for that to happen, the economics have to work.” He added that the official “nation-building” designation could give Nova Scotia “a seat at the table” with major utilities in other provinces.

The governments of Canada and Nova Scotia recently issued a notice of strategic direction to the Canada–Nova Scotia Offshore Energy Regulator, aligning with Ottawa’s plan to regulate offshore wind as it begins a prequalification process and designs a call for bids later this year. The initial round will cover just 3 GW of capacity — smaller than the originally envisioned 5 GW — but officials describe it as a first step in a multi-decade plan.

While timing and economics remain uncertain, supporters insist the long-term potential of offshore wind in Nova Scotia is too significant to ignore. As global demand for clean electricity grows and offshore wind moves toward a trillion-dollar global market, they argue, West Wind could help secure Canada’s place as a renewable energy leader — if government and industry can find a way to make the numbers work.

4 European nations to build North Sea wind farms

North Sea Offshore Wind Farms will deliver 150 GW by 2050 as EU partners scale renewable energy, offshore turbines, grid interconnectors, and REPowerEU goals to cut emissions, boost energy security, and reduce Russian fossil dependence.

 

Key Points

A joint EU initiative to build 150 GW of offshore wind by 2050, advancing REPowerEU, decarbonization, and energy security.

✅ Targets at least 150 GW of offshore wind by 2050

✅ Backed by Belgium, Netherlands, Germany, and Denmark

✅ Aligns with REPowerEU, grid integration, and emissions cuts

 

Four European Union countries plan to build North Sea wind farms capable of producing at least 150 gigawatts of energy by 2050 to help cut carbon emissions that cause climate change, with EU wind and solar surpassing gas last year, Danish media have reported.

Under the plan, wind turbines would be raised off the coasts of Belgium, the Netherlands, Germany and Denmark, where a recent green power record highlighted strong winds, daily Danish newspaper Jyllands-Posten said.

The project would mean a tenfold increase in the EU's current offshore wind capacity, underscoring how renewables are crowding out gas across Europe today.

“The North Sea can do a lot," Danish Prime Minister Frederiksen told the newspaper, adding the close cooperation between the four EU nations "must start now.”

European Commission President Ursula von der Leyen, German Chancellor Olaf Scholz, Dutch Prime Minister Mark Rutte and Belgian Prime Minister Alexander De Croo are scheduled to attend a North Sea Summit on Wednesday in Esbjerg, 260 kilometers (162 miles) west of Copenhagen.

In Brussels, the European Commission moved Wednesday to jump-start plans for the whole 27-nation EU to abandon Russian energy amid the Kremlin’s war in Ukraine. The commission proposed a nearly 300 billion-euro ($315 billion) package that includes more efficient use of fuels and a faster rollout of renewable power, even as stunted hydro and nuclear output may hobble recovery efforts.

The investment initiative by the EU's executive arm is meant to help the bloc start weaning themselves off Russian fossil fuels this year, even as Europe is losing nuclear power during the transition. The goal is to deprive Russia, the EU’s main supplier of oil, natural gas and coal, of tens of billions in revenue and strengthen EU climate policies.

“We are taking our ambition to yet another level to make sure that we become independent from Russian fossil fuels as quickly as possible,” von der Leyen said in Brussels when announcing the package, dubbed REPowerEU.

The EU has pledged to reduce carbon dioxide emissions by 55% compared with 1990 levels by 2030, and to get to net zero emissions by 2050, with a recent German renewables milestone underscoring the pace of change.

The European Commission has set an overall target of generating 300 gigawatts of offshore energy of by 2050, though grid expansion challenges in Germany highlight hurdles.

Along with climate change, the war in Ukraine has made EU nations eager to reduce their dependency on Russian natural gas and oil. In 2021, the EU imported roughly 40% of its gas and 25% of its oil from Russia.

At a March 11 summit, EU leaders agreed in principle to phase out Russian gas, oil and coal imports by 2027.

Use of electric vehicles associated with fewer asthma-related ER visits on a local level, study shows

Electric Vehicle Adoption Benefits include reduced air pollution, lower greenhouse gas emissions, and improved respiratory health, as regional studies show, with equity considerations for low-income communities and policy mandates accelerating zero-emission vehicles.

 

Key Points

The environmental and health gains from wider EV uptake, including cleaner air, lower emissions, and fewer asthma cases.

✅ Regional EV growth linked to lower NO2 and PM2.5 levels

✅ Fewer asthma ER visits in higher EV-adoption areas

✅ Address adoption gap to ensure equity in low-income communities

 

In an effort to mitigate the effects of climate change, countries across the globe are involving electric vehicles in their plans to reduce greenhouse gas emissions, citing the EV climate and cost benefits highlighted by recent analyses.

A federal mandate in Canada, for instance, aims to ensure that one-fifth of all passenger cars, SUVs and trucks sold in Canada are electrically-powered by 2026, with Ottawa set to release EV sales regulations to guide industry. By 2035, if this mandate is carried out, every passenger vehicle sold in Canada will need to be electric, though some critics deem the 2035 target unrealistic based on current conditions.

But what will this shift to electric vehicles actually do for the environment, especially given that 18% of Canada's 2019 electricity came from fossil fuels which affects lifecycle emissions?

One team of researchers with the Keck School of Medicine of USC aimed to find out, conducting what it describes as one of the first studies to analyze the environmental and health impacts of electric vehicles on a regional scale. Their research linked the wider integration of zero-emission vehicles with lower levels of local air pollution and some respiratory problems, a pattern consistent with analyses showing EVs are greener across all 50 states in the U.S.

“When we think about the actions related to climate change, often it’s on a global level,” Erika Garcia, an assistant professor of population and public health at the Keck School of Medicine, said in a press release.

“But the idea that changes being made at the local level can improve the health of your own community could be a powerful message to the public and to policy makers.”

Using data that spanned from 2013 to 2019, Garcia and the team of researchers compared the registration of zero-emissions vehicles with air pollution levels and asthma-related emergency room visits in California. They found that in regions where more electric vehicles were adopted, emergency room visits dropped, along with with pollution levels.

Sandrah Eckel, an associate professor of population and public health sciences and the study’s senior author, said their findings offer hope among a reality of climate anxieties.

“We’re excited about shifting the conversation towards climate change mitigation and adaptation, and these results suggest that transitioning to [electric vehicles] is a key piece of that.”

Garcia added that the study also evaluated disadvantages faced by those living in lower-income communities, which often see higher pollution levels and related respiratory problems, underscoring that EVs are not a silver bullet in broader climate and health policy.

Researchers discovered that adoption of zero-emissions vehicles in low-resource neighbourhoods was slower compared to more affluent areas, amid ongoing debate over whether EV purchase subsidies are an effective tool for Canada.

The study attributes this disparity to what the researchers call an “adoption gap” – referring to groups of people that cannot afford newer vehicles that are electrically-powered.


According to the study, which was published in the journal Science of the Total Environment, the adoption gap “threatens the equitable distribution of possible co-benefits.”

“Should continuing research support our findings, we want to make sure that those communities that are overburdened with traffic-related air pollution are truly benefiting from this climate mitigation effort,” Garcia said in the release.

Most planned U.S. battery storage additions in next three years to be paired with solar

U.S. Solar-Plus-Storage Growth 2021-2024 highlights rising battery storage co-location with solar PV, grid flexibility, RTO/ISO market signals, and ITC incentives, enabling peak shaving, firming renewable output, and reliable night-time power.

 

Key Points

Summary of U.S. plans pairing battery storage with solar PV, guided by RTO/ISO markets, grid needs, and ITC policy.

✅ 9.4 GW (63%) co-located with solar PV by 2024

✅ 97% of standalone capacity sited in RTO/ISO regions

✅ ITC improves project economics and grid services revenue

 

Of the 14.5 gigawatts (GW) of battery storage power capacity planned to come online amid anticipated growth in solar and storage in the United States from 2021 to 2024, 9.4 GW (63%) will be co-located with a solar photovoltaic (PV) solar-plus-storage power plant, based on data reported to us and published in our Annual Electric Generator Report. Another 1.3 GW of battery storage will be co-located at sites with wind turbines or fossil fuel-fired generators, such as natural gas-fired plants. The remaining 4.0 GW of planned battery storage will be located at standalone sites.

Historically, most U.S. battery systems have been located at standalone sites. Of the 1.5 GW of operating battery storage capacity in the United States at the end of 2020, 71% was standalone, and 29% was located onsite with other power generators.

Most standalone battery energy storage sites have been planned or built in power markets that are governed by regional transmission organizations (RTOs) and independent system operators (ISOs). RTOs and ISOs can enforce standard market rules that lay out clear revenue streams for energy storage projects in their regions, which promotes the deployment of battery storage systems. Of the utility-scale pipeline battery systems announced to come online from 2021 to 2024, 97% of the standalone battery capacity and 60% of the co-located battery capacity are in RTO/ISO regions.

Over 90% of the planned battery storage capacity outside of RTO and ISO regions will be co-located with a solar PV plant. At some solar PV co-located plants, the batteries can charge directly from the onsite solar generator when electricity demand and prices are low. They can then discharge electricity to the grid when peak demand is higher or when solar generation is unavailable, such as at night.

Although factors such as cloud cover can affect solar generation output, solar generators, now the number three renewable source in the U.S., in particular can effectively pair with battery storage because of their relatively regular daily generation patterns. This predictability works well with battery systems because battery systems are limited in how long they can discharge their power capacity before needing to recharge. If paired with a wind turbine, for example, a battery system could go days before having the opportunity to fully recharge.

Another advantage of pairing batteries with renewable generators is the ability to take advantage of tax incentives such as the Investment Tax Credit (ITC), which is available for solar projects, and other favorable government plans supporting deployment.
