US Plug-in EV Miles 2021 highlight BEV and PHEV growth, DOE and Argonne data, 19.1 billion electric miles, 6.1 TWh consumed, gasoline savings, rising market share, and battery capacity deployed across the US light-duty fleet.

 

Key Points

They represent 19.1 billion electric miles by US BEVs and PHEVs in 2021, consuming 6.1 TWh of electricity.

✅ 700 million gallons gasoline avoided in 2021

✅ $1.3 billion fuel cost savings estimated

✅ Cumulative 68 billion EV miles since 2010

 

Plug-in electric cars are gradually increasing their market share in the US (reaching about 4% in 2021), which starts to make an impact even as the U.S. EV market share saw a brief dip in Q1 2024.

The Department of Energy (DOE)’s Vehicle Technologies Office highlights in its latest weekly report that in 2021, plug-ins traveled some 19.1 billion miles (31 billion km) on electricity - all miles traveled in BEVs and the EV mode portion of miles traveled in PHEVs, underscoring grid impacts that could challenge state power grids as adoption grows.

This estimated distance of 19 billion miles is noticeably higher than in 2020 (nearly 13 billion miles), which indicates how quickly the electrification of driving progresses, with U.S. EV sales continuing to soar into 2024. BEVs noted a 57% year-over-year increase in EV miles, while PHEVs by 24% last year (mostly proportionally to sales increase).

According to Argonne National Laboratory's Assessment of Light-Duty Plug-in Electric Vehicles in the United States, 2010–2021, the cumulative distance covered by plug-in electric cars in the US (through December 2021) amounted to 68 billion miles (109 billion miles).

U.S. Department of Transportation, Federal Highway Administration, December 2021 Traffic Volume Trends, 2022.

The report estimates that over 2.1 million plug-in electric cars have been sold in the US through December 2021 (about 1.3 million all-electric and 0.8 million plug-in hybrids), equipped with a total of more than 110 GWh of batteries, even as EV sales remain behind gas cars in overall market share.

It's also estimated that 19.1 billion electric miles traveled in 2021 reduced the national gasoline consumption by 700 million gallons of gasoline or 0.54%.

On the other hand, plug-ins consumed some 6.1 terawatt-hours of electricity (6.1 TWh is 6,100 GWh), which sounds like almost 320 Wh/mile (200 Wh/km), aligning with projections that EVs could drive a rise in U.S. electricity demand over time.

The difference between the fuel cost and energy cost in 2021 is estimated at $1.3 billion, with Consumer Reports findings further supporting the total cost advantages.

Cumulatively, 68 billion electric miles since 2010 is worth about 2.5 billion gallons of gasoline. So, the cumulative savings already is several billion dollars.

Those are pretty amazing numbers and let's just imagine that electric cars are just starting to sell in high volume, a trend that mirrors global market growth seen over the past decade. Every year those numbers will be improving, thus tremendously changing the world that we know today.

Report: Canada's renewable energy growth projections scaled back after Ontario scraps clean energy program

Canada Renewable Energy Outlook highlights IEA forecasts of slower capacity growth as Ontario cancels LRP auctions; wind, solar, and hydro expand amid carbon pricing, coal phase-out, Alberta tenders, and falling costs despite natural gas competition.

 

Key Points

The Canada Renewable Energy Outlook distills IEA projections and policies behind wind, solar, and hydro growth to 2022.

✅ IEA trims Canada renewables growth to 9 GW by 2022

✅ Ontario LRP cuts and Quebec tenders reduce near-term additions

✅ Wind, solar, hydro expand amid carbon pricing and coal phase-out

 

A new report expects growth in Canadian renewable energy capacity to slow in the next five years compared to earlier projections, a decrease that comes after Ontario scrapped a contentious clean energy program aimed at boosting wind and solar supplies.

The International Energy Agency’s annual outlook for renewable energy, released Wednesday, projects Canada’s renewable capacity to grow by nine gigawatts between 2017 and 2022, down from last year’s report that projected capacity would grow by 13GW.

The influential Paris-based agency said its recent outlook for Canadian renewables was “less optimistic” than its 2016 projection due to “recent changes in auctions schemes in Ontario and Quebec.”

 

PROGRAM CUTS

In mid-2016 the Ontario government suspended the second phase of its Large Renewable Procurement (LPR) program, axing $3.8 billion in planned renewable energy contracts. And Quebec cancelled tenders for several clean energy projects, which also led the agency to trim its forecasts, the report said.

Ontario cut the LRP program amid anger over rising electricity bills, which critics said was at least partly due to the rapid expansion of wind power supplies across the province.

Experts said the rise in costs was also partly due to major one-time costs to maintain aging infrastructure, particularly the $12.8-billion refurbishment of the Darlington nuclear plant located east of Toronto. The province also has plans to renovate the nearby Pickering nuclear plant in coming years.

The IEA report comes as Ottawa aims to drastically cut carbon emissions, largely by expanding renewable energy capacity. The provinces, including the Prairie provinces, have meanwhile been looking to pare back emissions by phasing out coal and implementing a carbon tax.

While Ontario’s decision to scrap the LRP program is a minor setback in the near-term, analysts say that tightening environmental policy in Canada and elsewhere will regardless continue to drive rapid growth in renewable energy supplies like wind power and solar.

Even the threat of cheap supplies of natural gas, a major competitor to renewable supplies, is unlikely to keep wind and solar supplies off the market, despite lagging solar demand in some regions, as costs continue to fall.

“It’s not just this (Ontario) renewables program, it’s the carbon pricing program, the coal phase out, a whole plethora of programs that are squeezing natural gas margins,” said Dave Sawyer, an economist at EnviroEconomics in Ottawa.

 

RENEWABLE ENERGY CAPACITY

Canada’s renewable energy capacity is still expected to grow at a robust 10 per cent per year, the report said, and is expected to supply 69 per cent of overall power generation in the country by 2022.

The IEA, however, expects the growth in hydro power capacity to “slow significantly” beyond 2022, after a raft of new hydro projects come online.

Canadian hydro power capacity is projected to grow 2.2GW in the next five years, mostly due to the commissioning of the Keeyask plant in Manitoba the Muskrat Falls dam in Newfoundland and Labrador and the Romaine 3 and 4 stations in Quebec, in a sector where Canada ranks in the top 10 for hydropower jobs nationwide.

Solar capacity in Canada is expected to grow by 2GW to 4.7GW in 2022, approaching the 5 GW milestone in the near term, mostly due to feed-in-tariff programs in Ontario and renewable energy tenders currently underway in Alberta.

Globally, China and India lead renewable capacity growth projections. China alone is expected to be responsible for 40 per cent of renewable capacity growth in the next five years, while India will double its renewable electricity capacity by 2022. The world is collectively expected to grow renewable electricity capacity by 43 per cent between 2017 and 2022.

Why Electric Vehicles Are "Greener" Than Ever In All 50 States

UCS EV emissions study shows electric vehicles produce lower life-cycle emissions than gasoline cars across all states, factoring tailpipe, grid mix, power plant sources, and renewable energy, delivering mpg-equivalent advantages nationwide.

 

Key Points

UCS study comparing EV and gas life-cycle emissions, finding EVs cleaner than new gas cars in every U.S. region.

✅ Average EV equals 93 mpg gas car on emissions.

✅ Cleaner than 50 mpg gas cars in 97% of U.S.

✅ Regional grid mix included: tailpipe to power plant.

 

One of the cautions cited by electric vehicle (EV) naysayers is that they merely shift emissions from the tailpipe to the local grid’s power source, implicating state power grids as a whole, and some charging efficiency claims get the math wrong, too. And while there is a kernel of truth to this notion—they’re indeed more benign to the environment in states where renewable energy resources are prevalent—the average EV is cleaner to run than the average new gasoline vehicle in all 50 states. 

That’s according to a just-released study conducted the Union of Concerned Scientists (UCS), which determined that global warming emissions related to EVs has fallen by 15 percent since 2018. For 97 percent of the U.S., driving an electric car is equivalent or better for the planet than a gasoline-powered model that gets 50 mpg. 

In fact, the organization says the average EV currently on the market is now on a par, environmentally, with an internal combustion vehicle that’s rated at 93 mpg. The most efficient gas-driven model sold in the U.S. gets 59 mpg, and EV sales still trail gas cars despite such comparisons, with the average new petrol-powered car at 31 mpg.

For a gasoline car, the UCS considers a vehicle’s tailpipe emissions, as well as the effects of pumping crude oil from the ground, transporting it to a refinery, creating gasoline, and transporting it to filling stations. For electric vehicles, the UCS’ environmental estimates include both emissions from the power plants themselves, along with those created by the production of coal, natural gas or other fossil fuels used to generate electricity, and they are often mischaracterized by claims about battery manufacturing emissions that don’t hold up. 

Of course the degree to which an EV ultimately affects the atmosphere still varies from one part of the country to another, depending on the local power source. In some parts of the country, driving the average new gasoline car will produce four to eight times the emissions of the average EV, a fact worth noting for those wondering if it’s the time to buy an electric car today. The UCS says the average EV driven in upstate New York produces total emissions that would be equivalent to a gasoline car that gets an impossible 255-mpg. In even the dirtiest areas for generating electricity, EVs are responsible for as much emissions as a conventionally powered car that gets over 40 mpg.

More Electricity From Wind & Solar Than Nuclear For 1st Time In USA

U.S. Renewable Energy Share 2022 leads electricity generation trends, as wind and solar outpace nuclear and coal, per EIA data, with hydropower gains and grid growth highlighting rapid, sustainable capacity expansion nationwide.

 

Key Points

Renewables supplied over 25% of U.S. electricity in 2022, as wind and solar outpaced nuclear with double-digit growth.

✅ Renewables provided 25.52% of U.S. power Jan-Apr 2022.

✅ Wind and solar beat nuclear by 17.96% in April.

✅ Solar up 28.93%, wind up 24.25%; hydropower up 9.99%.

 

During the first four months of 2022, electrical generation by renewable energy sources accounted for over 25% of the nation’s electricity, projected to soon be about one-fourth as growth continues. In April alone, renewables hit a record April share of 29.3% — an all-time high.

And for the first time ever, the combination of just wind power and solar produce more electricity in April than the nation’s nuclear power plants — 17.96% more.

This is according to a SUN DAY Campaign analysis of data in EIA’s Electric Power Monthly report. The report also reveals that during the first third of this year, solar (including residential) generation climbed by 28.93%, while wind increased by 24.25%. Combined, solar and wind grew by 25.46% and accounted for more than one-sixth (16.67%) of U.S. electrical generation (wind: 12.24%, solar: 4.43%).

Hydropower also increased by 9.99% during the first four months of 2022. However, wind alone provided 70.89% more electricity than did hydropower. Together with contributions from geothermal and biomass, the mix of renewable energy sources expanded by 18.49%, and building on its second-most U.S. source in 2020 status helped underscore momentum as it provided about 25.5% of U.S. electricity during the first four months of 2022.

For the first third of the year, renewables surpassed coal and nuclear power by 26.13% and 37.80% respectively. In fact, electrical generation by coal declined by 3.94% compared to the same period in 2021 while nuclear dropped by 1.80%.

“Notwithstanding headwinds such as the COVID pandemic, grid access problems, and disruptions in global supply chains, solar and wind remain on a roll,” noted the SUN DAY Campaign’s executive director Ken Bossong. “Moreover, by surpassing nuclear power by ever greater margins, they illustrate the foolishness of trying to revive the soon-to-retire Diablo Canyon nuclear plant in California and the just-retired Palisades reactor in Michigan rather than focusing on accelerating renewables’ growth.”

Scrapping coal-fired electricity costly, ineffective, says report

Canada Coal Phase-Out Costs highlight Fraser Institute findings on renewable energy, wind and solar integration, grid reliability, natural gas backup, GDP impacts, greenhouse gas emissions reductions, nuclear alternatives, and transmission upgrades across provincial electricity systems.

 

Key Points

Costs to replace coal with renewables, impacting taxpayers and ratepayers while ensuring grid reliability.

✅ Fraser Institute estimates $16.8B-$33.7B annually for renewables.

✅ Emissions cut from coal phase-out estimated at only 7.4% nationally.

✅ Natural gas backup and grid upgrades drive major cost increases.

 

Replacing coal-fired electricity with renewable energy will cost Canadian taxpayers and hydro ratepayers up to $33.7 billion annually, with only minor reductions in global greenhouse gas emissions linked to climate change, according to a new study by the Fraser Institute.

The report, Canadian Climate Policy and its Implications for Electricity Grids by University of Victoria economics professor G. Cornelis van Kooten, said replacing coal-fired electricity with wind and solar power would only cut Canada’s annual emissions by 7.4%,

Prime Minister Justin Trudeau’s has promised a reduction of 40%-45% compared to Canada’s 2005 emissions by 2030, and progress toward the 2035 clean electricity goals remains uncertain.

The study says emission cuts would be relatively small because coal accounted for only 9.2% of Canada’s electricity generation in 2017. (According to Natural Resources Canada, that number is lower today at 7.4%).

In 2019, the last year for which federal data are available, Canada’s electricity sector generated 8.4% of emissions nationally — 61.1 million tonnes out of 730 million tonnes.

“Despite what advocates, claim, renewable power — including wind and solar — isn’t free and, as Europe's power crisis lessons suggest, comes with only modest benefits to the environment,” van Kooten said.

“Policy makers should be realistic about the costs of reducing greenhouse gas emissions in Canada, which accounts for less than 2% of emissions worldwide.”

The report says the increased costs of operating the electricity grid across Canada — between $16.8 billion and $33.7 billion annually or 1% to 2% of Canada’s annual GDP — would result from having to retain natural gas, consistent with net-zero regulations allowing some natural gas in limited cases, as a backup to intermittent wind and solar power, which cannot provide baseload power to the electricity grid on demand.

Van Kooten said his cost estimates are conservative because his study “could not account for scenarios where the scale of intermittency turned out worse than indicated in our dataset … the costs associated with the value of land in other alternative uses, the need for added transmission lines, as analyses of greening Ontario's grid costs indicate, environmental and human health costs and the life-cycle costs of using intermittent renewable sources of energy, including costs related to the disposal of hazardous wastes from solar panels and wind turbines.”

If nuclear power was used to replace coal-fired electricity, the study says, costs would drop by half — $8.3 billion to $16.7 billion annually — but that’s unrealistic because of the time it takes to build nuclear plants and public opposition to them.

The study says to achieve the federal government’s target of reducing emissions to 40% to 45% below 2005 levels by 2030 and net-zero emissions by 2050, would require building 30 nuclear power plants before 2030, highlighting Canada’s looming power problem as described by analysts — meaning one plant of 1,000-megawatt capacity coming online every four months between now and 2030.

Alternatively, it would take 28,340 wind turbines, each with 2.5-megawatts capacity, or 1,050 turbines being built every four months, plus the costs of upgrading transmission infrastructure.

Van Kooten said he based his calculations on Alberta, which generates 39.8% of its electricity from coal and the cost of Ontario eliminating coal-fired electricity, even as Ontario electricity getting dirtier in coming years, which generated 25% of its electricity, between 2003 and 2014, replacing it with a combination of natural gas, nuclear and wind and solar power.

According to Natural Resources Canada, Nova Scotia generates 49.9% of its electricity from coal, Saskatchewan 42.9%, and New Brunswick 17.2%.

In 2018, the Trudeau government announced plans to phase-out traditional coal-fired electricity by 2030, though the Stop the Shock campaign seeks to bring back coal power in some regions. 

Canada and the U.K. created the “Powering Past Coal Alliance” in 2017, aimed at getting other countries to phase out the use of coal to generate electricity.

These companies are using oceans and rivers to generate electricity

Tidal Energy harnesses ocean currents with tidal turbines to deliver predictable, renewable power. From Scotland's Orkney to New York's East River, clean baseload electricity complements wind and solar in decarbonizing grids.

 

Key Points

Tidal energy uses underwater turbines to capture predictable ocean currents, delivering reliable, low-carbon power.

✅ Predictable 2-way flows enable forecastable baseload

✅ Higher energy density than wind, slower flow speeds

✅ Costs remain high; scaling and deployment are challenging

 

As the world looks to curb climate change and reduce fossil fuel emissions, some companies are focusing on a relatively untapped but vast and abundant source of energy — tidal waves.

On opposite sides of the Atlantic, two firms are working to harness ocean currents in different ways to try to generate reliable clean energy.

Off the coast of Scotland, Orbital Marine Power operates what it says is the "most powerful tidal turbine in the world." The turbine is approximately the size of a passenger airplane and even looks similar, with its central platform floating on the water and two wings extending downwards on either side. At the ends of each wing, about 60 feet below the surface, are large rotors whose movement is dictated by the waves.

"The energy itself of tidal streams is familiar to people, it's kinetic energy, so it's not too dissimilar to something like wind," Andrew Scott, Orbital's CEO, told CNN Business. "The bits of technology that generate power look not too different to a wind turbine."

But there are some key differences to wind energy, primarily that waves are far more predictable than winds. The ebb and flow of tides rarely differs significantly and can be timed far more precisely.

Orbital Marine Power's floating turbines off the Scottish coast produce enough energy to power 2,000 homes a year, while another Scottish tidal project recently produced enough for nearly 4,000 homes.

Orbital Marine Power's floating turbines off the Scottish coast produce enough energy to power 2,000 homes a year.

"You can predict those motions years and decades [in] advance," Scott said. "But also from a direction perspective, they only really come from two directions and they're almost 180 degrees," he added, unlike wind turbines that must account for wind from several different directions at once.

Tidal waves are also capable of generating more energy than wind, Scott says.

"Seawater is 800 times the density of wind," he said. "So the flow speeds are far slower, but they generate far more energy."

The Orbital turbine, which is connected to the electricity grid in Scotland's Orkney, can produce up to two megawatts — enough to power 2,000 homes a year — according to the company.

Scott acknowledges that the technology isn't fully mainstream yet and some challenges remain including the high cost of the technology, but the reliability and potential of tidal energy could make it a useful tool in the fight against climate change, as projects like Sustainable Marine in Nova Scotia begin delivering power to the grid.

"It is becoming increasingly apparent that ... climate change is not going to be solved with one silver bullet," he said.


'Could be 24/7 power'
Around 3,000 miles away from Orbital's turbines, Verdant Power is using similar technology to generate power near Roosevelt Island in New York City's East River. Although not on the market yet, Verdant's turbines set up as part of a pilot project help supply electricity to New York's grid. But rather than float near the surface, they're mounted on a frame that's lowered to the bottom of the river.

"The best way to envision what Verdant Power's technology is, is to think of wind turbines underwater," the company's founder, Trey Taylor, told CNN Business. And river currents tend to provide the same advantages for energy generation as ocean currents, he explained (though the East River is also connected to the Atlantic).

"What's nice about our rivers and systems is that could be 24/7 power," he said, even as U.S. offshore wind aims to compete with gas. "Not to ding wind or solar, but the wind doesn't always blow and the sun doesn't always shine. But river currents, depending on the river, could be 24/7."

Verdant Power helps supply electricity to New York City
Over the course of eight months, Verdant has generated enough electricity to power roughly 60 homes — though Taylor says a full-fledged power plant built on its technology could generate enough for 6,000 homes. And by his estimate, the global capacity for tidal energy is enormous, with regions like the Bay of Fundy pursuing new attempts around Nova Scotia.


A costly technology
The biggest obstacle to reaching that goal at the moment is how expensive it is to set up and scale up tidal power systems.

"Generating electricity from ocean waves is not the challenge, the challenge is doing it in a cost-effective way that people are willing to pay for that competes with ... other sources of energy," said Jesse Roberts, Environmental Analysis Lead at the US government-affiliated Sandia National Laboratories. "The added cost of going out into the ocean and deploying in the ocean... that's very expensive to do," he added. According to 2019 figures from the US Department of Energy, the average commercial tidal energy project costs as much as $280 per megawatt hour. Wind energy, by comparison, currently costs roughly $20 per megawatt hour and is "one of the lowest-priced energy sources available today," with major additions like the UK's biggest offshore wind farm starting to supply the grid, according to the agency.

When operational, the Orbital turbine's wing blades drop below the surface of the water and generate power from ocean currents.

When operational, the Orbital turbine's wing blades drop below the surface of the water and generate power from ocean currents.

Roberts estimates that tidal energy is two or three decades behind wind energy in terms of adoption and scale.

The costs and challenges of operating underwater are something both Scott and Taylor acknowledge.
"Solar and wind are above ground. It's easy to work with stuff that you can see," Taylor said. "We're underwater, and it's probably easier to get a rocket to the moon than to get these to work underwater."
But the goal of tidal power is not so much to compete with those two energy sources as it is to grow the overall pie, alongside innovations such as gravity power that can help decarbonize grids.

"The low hanging fruit of solar and wind were quite obvious," Scott said. "But do they have to be the only solution? Is there room for other solutions? I think when the energy source is there, and you can develop technologies that can harness it, then absolutely."

UK firm plans to operate Vietnam mega wind power project by 2025

ThangLong Wind Project Vietnam targets $12b, 3,400 MW offshore wind in Binh Thuan, aligned with PDP8, 2025-2028 timeline, EVN grid integration, and private transmission lines to support renewable energy growth and local industry.

 

Key Points

A $12b, 3,400 MW offshore wind farm off Binh Thuan, aiming first power by 2025 and full capacity by 2028.

✅ 20-60 km offshore; 30-55 m water depth site

✅ Seeks licenses for private transmission lines, beyond EVN

✅ 50% local spend; boosts supply chain and jobs

 

U.K. energy firm Enterprize Energy, reflecting momentum in UK offshore wind, wants to begin operating its $12-billion offshore wind power project in central Vietnam by the end of 2025.
Company chairman Ian Hatton proposed the company’s ThangLong Wind Project in the central province of Binh Thuan be included in Vietnam’s 8th National Power Development Plan, which is being drafted at present, so that at least part of the project can begin operations by the end of 2025 and all of it by 2028.

Renewable energy is a priority in the development plan that the Ministry of Industry and Trade will submit to the government next month. About 37.5 percent of new energy supply in the next decade will come from renewable energy, aligning with wind leading the power mix trends globally, it envisages.

However, due to concerns of overload to the national grid, and as build-outs like North Sea wind farms show similar coordination needs, Hatton, at a Wednesday meeting with Prime Minister Nguyen Xuan Phuc and U.K. Minister of State for Trade Policy Greg Hands, proposed the government gives Enterprize Energy licenses to develop transmission lines to handle future output.

Developing transmission lines in Vietnam has been the exclusive preserve of the national utility Vietnam Electricity (EVN), and large domestic projects such as the Hoa Binh hydropower expansion have typically aligned with this framework.

The 3,400-megawatt ThangLong Wind Project is to be located between 20 and 60 kilometers off the coast of Binh Thuan, mirroring international interest where Japanese utilities in UK offshore wind have scaled similar assets, at a depth of 30-55 meters. Enterprize Energy had said wind resources in this area exceed its expectations.

The project’s construction is expected to stimulate Vietnam’s economic growth, and experiences from U.S. offshore wind competitiveness suggest improving economics, with 50 percent of construction and operational expenses made locally.

Vietnam needs $133.3 billion over the next decade for building new power plants and expanding the grid to meet the growing demand for electricity, while regional agreements like a Bangladesh power supply deal illustrate rising demand, the ministry has estimated.
