Electric vehicles can now power your home for three days

Ontario Renewable Energy Procurement 2024 will see the IESO secure wind, solar, and hydro power to meet rising electricity demand, support transit electrification, bolster grid reliability, and serve manufacturing growth across the province.

Key Points

A provincial IESO initiative to add 2,000 MW of clean power and plan 3,000 MW more to meet rising demand.

✅ IESO to procure 2,000 MW from wind, solar, hydro

✅ Exploring 3,000 MW via upgrades and expansions

✅ Demand growth ~2% yearly; electrification and industry

After the Ford government terminated renewable energy contracts five years ago, despite warnings about wind project cancellation costs that year, Ontario's electricity operator, the Independent Electricity System Operator (IESO), is now planning to once again incorporate wind and solar initiatives to address the province's increasing power demands.

The IESO, responsible for managing the provincial power supply, is set to secure 2,000 megawatts of electricity from clean sources, which include wind, solar, and hydro power, as wind power competitiveness increases across Canada. Additionally, the IESO is exploring the possibilities of reacquiring, upgrading, or expanding existing facilities to generate an additional 3,000 MW of electricity in the future.

These new power procurement efforts in Ontario aim to meet the rising energy demand driven by transit electrification and large-scale manufacturing projects, even as national renewable growth projections were scaled back after Ontario scrapped its clean energy program, which are expected to exert greater pressure on the provincial grid.

The IESO projects a consistent growth in demand of approximately two percent per year over the next two decades. This growth has prompted the Ford government, amid debate over Ontario's electricity future in the province, to take proactive measures to prevent potential blackouts or disruptions for both residential and commercial consumers.

This renewed commitment to renewable energy represents a significant policy shift for Premier Doug Ford, reflecting his new stance on wind power over time, who had previously voiced strong opposition to wind turbines and pledged to dismantle all windmills in the province. In 2018, shortly after taking office, the government terminated 750 renewable energy contracts that had been signed by the previous Liberal government, incurring fees of $230 million for taxpayers.

At the time, the government cited reasons such as surplus electricity supply and increased costs for ratepayers as grounds for contract cancellations. Premier Ford expressed pride in the decision, echoing a proud of cancelling contracts stance, claiming that it saved taxpayers $790 million and eliminated what he viewed as detrimental wind turbines that had negatively impacted the province's energy landscape for 15 years.

The Ontario government's new wind and solar energy procurement initiatives are scheduled to commence in 2024, following a court ruling on a Cornwall wind farm that spotlighted cancellation decisions.

California Electric School Bus Mandate 2035 sets zero-emission requirements, outlines funding, state reimbursement, fleet electrification, infrastructure, and cost estimates, highlighting exemptions for frontier districts and alignment with clean transportation and climate policy goals.

Key Points

California's 2035 policy requires all new school buses be zero-emission, with funding and limited rural exemptions.

✅ Mandates zero-emission purchases for new school buses from 2035

✅ Estimates $5B transition cost with state reimbursement support

✅ Frontier districts may apply for 5-year extensions

California Governor Gavin Newsom has signed a new legislation requiring that from 2035, all newly ordered or contracted school buses must be zero-emission, a move aligned with California's push for expanded EV grid capacity statewide.

The state estimates that switching to electric school buses will cost around five billion dollars over the next decade, a projection reflecting electric bus challenges seen globally. That is because a diesel equivalent costs about 200,000 dollars less than a battery-electric version, as highlighted by critical analyses of California policy. And “the California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state.”

There are about 23,800 school buses on the road in California. About 500 are already electric, with conversion initiatives expected to expand the total, and 2,078 electric buses have been ordered.

There are – as always- exceptions to the rule. So-called “frontier districts,” which have less than 600 students or are in a county with a population density of less than ten persons per square mile, can file for a five-year extension, drawing on lessons from large electric bus fleets about route length and charging constraints. However, they must “reasonably demonstrate that a daily planned bus route for transporting pupils to and from school cannot be serviced through available zero-emission technology in 2035.”

Califonia is the fifth US state to mandate electric school buses, and jurisdictions like British Columbia are deploying electric school buses as well. Connecticut, Maryland, Maine, and New York implemented similar legislation, while California continues broader zero-emission freight adoption with Volvo VNR electric trucks entering service across the state.

Vehicle-to-Grid V2G unlocks EV charging flexibility and grid services, integrating renewable energy, demand response, and peak shaving to displace stationary storage and firm generation while lowering system costs and enhancing reliability.

Key Points

Vehicle-to-Grid V2G lets EV batteries discharge to grid, balancing renewables and cutting storage and firm generation.

✅ Displaces costly stationary storage and firm generation

✅ Enables demand response and peak shaving at scale

✅ Supports renewable integration and grid reliability

Owners of electric vehicles (EVs) are accustomed to plugging into charging stations at home and at work and filling up their batteries with electricity from the power grid. But someday soon, when these drivers plug in, their cars will also have the capacity to reverse the flow and send electrons back to the grid. As the number of EVs climbs, the fleet’s batteries could serve as a cost-effective, large-scale energy source, with potentially dramatic impacts on the energy transition, according to a new paper published by an MIT team in the journal Energy Advances.

“At scale, vehicle-to-grid (V2G) can boost renewable energy growth, displacing the need for stationary energy storage and decreasing reliance on firm [always-on] generators, such as natural gas, that are traditionally used to balance wind and solar intermittency,” says Jim Owens, lead author and a doctoral student in the MIT Department of Chemical Engineering. Additional authors include Emre Gençer, a principal research scientist at the MIT Energy Initiative (MITEI), and Ian Miller, a research specialist for MITEI at the time of the study.

The group’s work is the first comprehensive, systems-based analysis of future power systems, drawing on a novel mix of computational models integrating such factors as carbon emission goals, variable renewable energy (VRE) generation, and costs of building energy storage, production, and transmission infrastructure.

“We explored not just how EVs could provide service back to the grid — thinking of these vehicles almost like energy storage on wheels providing flexibility — but also the value of V2G applications to the entire energy system and if EVs could reduce the cost of decarbonizing the power system,” says Gençer. “The results were surprising; I personally didn’t believe we’d have so much potential here.”

Displacing new infrastructure

As the United States and other nations pursue stringent goals to limit carbon emissions, electrification of transportation has taken off, with the rate of EV adoption rapidly accelerating. (Some projections show EVs supplanting internal combustion vehicles over the next 30 years.) With the rise of emission-free driving, though, there will be increased demand for energy on already stressed state power grids nationwide. “The challenge is ensuring both that there’s enough electricity to charge the vehicles and that this electricity is coming from renewable sources,” says Gençer.

But solar and wind energy is intermittent. Without adequate backup for these sources, such as stationary energy storage facilities using lithium-ion batteries, for instance, or large-scale, natural gas- or hydrogen-fueled power plants, achieving clean energy goals will prove elusive. More vexing, costs for building the necessary new energy infrastructure runs to the hundreds of billions.

This is precisely where V2G can play a critical, and welcome, role, the researchers reported. In their case study of a theoretical New England power system meeting strict carbon constraints, for instance, the team found that participation from just 13.9 percent of the region’s 8 million light-duty (passenger) EVs displaced 14.7 gigawatts of stationary energy storage. This added up to $700 million in savings — the anticipated costs of building new storage capacity.

Their paper also described the role EV batteries could play at times of peak demand, such as hot summer days. “With proper grid coordination practices in place, V2G technology has the ability to inject electricity back into the system to cover these episodes, so we don’t need to install or invest in additional natural gas turbines,” says Owens. “The way that EVs and V2G can influence the future of our power systems is one of the most exciting and novel aspects of our study.”

Modeling power

To investigate the impacts of V2G on their hypothetical New England power system, the researchers integrated their EV travel and V2G service models with two of MITEI’s existing modeling tools: the Sustainable Energy System Analysis Modeling Environment (SESAME) to project vehicle fleet and electricity demand growth, and GenX, which models the investment and operation costs of electricity generation, storage, and transmission systems. They incorporated such inputs as different EV participation rates, costs of generation for conventional and renewable power suppliers, charging infrastructure upgrades, travel demand for vehicles, changes in electricity demand, and EV battery costs.

Their analysis found benefits from V2G applications in power systems (in terms of displacing energy storage and firm generation) at all levels of carbon emission restrictions, including one with no emissions caps at all. However, their models suggest that V2G delivers the greatest value to the power system when carbon constraints are most aggressive — at 10 grams of carbon dioxide per kilowatt hour load. Total system savings from V2G ranged from $183 million to $1,326 million, reflecting EV participation rates between 5 percent and 80 percent.

“Our study has begun to uncover the inherent value V2G has for a future power system, demonstrating that there is a lot of money we can save that would otherwise be spent on storage and firm generation,” says Owens.

Harnessing V2G

For scientists seeking ways to decarbonize the economy, the vision of millions of EVs parked in garages or in office spaces and plugged into the grid via vehicle-to-building charging for 90 percent of their operating lives proves an irresistible provocation. “There is all this storage sitting right there, a huge available capacity that will only grow, and it is wasted unless we take full advantage of it,” says Gençer.

This is not a distant prospect. Startup companies are currently testing software that would allow two-way communication between EVs and grid operators or other entities. With the right algorithms, EVs would charge from and dispatch energy to the grid according to profiles tailored to each car owner’s needs, never depleting the battery and endangering a commute.

“We don’t assume all vehicles will be available to send energy back to the grid at the same time, at 6 p.m. for instance, when most commuters return home in the early evening,” says Gençer. He believes that the vastly varied schedules of EV drivers will make enough battery power available to cover spikes in electricity use over an average 24-hour period. And there are other potential sources of battery power down the road, such as electric school buses that are employed only for short stints during the day and then sit idle, with the potential to power buildings during peak hours.

The MIT team acknowledges the challenges of V2G consumer buy-in. While EV owners relish a clean, green drive, they may not be as enthusiastic handing over access to their car’s battery to a utility or an aggregator working with power system operators. Policies and incentives would help.

“Since you’re providing a service to the grid, much as solar panel users do, you could get paid to sell electricity back for your participation, and paid at a premium when electricity prices are very high,” says Gençer.

“People may not be willing to participate ’round the clock, but as states like California explore EVs for grid stability programs and incentives, if we have blackout scenarios like in Texas last year, or hot-day congestion on transmission lines, maybe we can turn on these vehicles for 24 to 48 hours, sending energy back to the system,” adds Owens. “If there’s a power outage and people wave a bunch of money at you, you might be willing to talk.”

“Basically, I think this comes back to all of us being in this together, right?” says Gençer. “As you contribute to society by giving this service to the grid, you will get the full benefit of reducing system costs, and also help to decarbonize the system faster and to a greater extent.”

Actionable insights

Owens, who is building his dissertation on V2G research, is now investigating the potential impact of heavy-duty electric vehicles in decarbonizing the power system. “The last-mile delivery trucks of companies like Amazon and FedEx are likely to be the earliest adopters of EVs,” Owen says. “They are appealing because they have regularly scheduled routes during the day and go back to the depot at night, which makes them very useful for providing electricity and balancing services in the power system.”

Owens is committed to “providing insights that are actionable by system planners, operators, and to a certain extent, investors,” he says. His work might come into play in determining what kind of charging infrastructure should be built, and where.

“Our analysis is really timely because the EV market has not yet been developed,” says Gençer. “This means we can share our insights with vehicle manufacturers and system operators — potentially influencing them to invest in V2G technologies, avoiding the costs of building utility-scale storage, and enabling the transition to a cleaner future. It’s a huge win, within our grasp.”

Electric vehicles may cost more upfront but often save money long-term. A new MIT study shows the total cost of EV ownership is lower than gas cars when factoring in fuel, maintenance, and emissions.

Total cost of EV ownership is the focus of new MIT research showing electric vehicles offer both financial and environmental benefits over time.

✅ Electric vehicles cost more upfront but save money over their lifetime through lower fuel and maintenance costs

✅ MIT study confirms EVs have lower emissions and total ownership costs than most gas-powered cars

✅ New interactive tool helps consumers compare climate and cost impacts of EVs, hybrids, and traditional vehicles

Electric vehicles are better for the climate than gas‑powered cars, but many Americans are still reluctant to buy them. One reason: The larger upfront cost.

New data published Thursday shows that despite the higher sticker price, electric cars may actually save drivers money in the long-run.

To reach this conclusion, a team at the Massachusetts Institute of Technology calculated both the carbon dioxide emissions and full lifetime cost — including purchase price, maintenance and fuel — for nearly every new car model on the market.

They found electric cars were easily more climate friendly than gas-burning ones. Over a lifetime, they were often cheaper, too.

Jessika Trancik, an associate professor of energy studies at M.I.T. who led the research, said she hoped the data would “help people learn about how those upfront costs are spread over the lifetime of the car.”

For electric cars, lower maintenance costs and the lower costs of charging compared with gasoline prices tend to offset the higher upfront price over time. (Battery-electric engines have fewer moving parts that can break compared with gas-powered engines and they don’t require oil changes. Electric vehicles also use regenerative braking, which reduces wear and tear.)

As EV adoption continues to boom, more consumers are realizing the long-term savings and climate benefits. Ontario’s investment in EV charging stations reflects how infrastructure is beginning to catch up with demand. Despite regional energy pricing differences, EV charging costs remain lower than gasoline in nearly every U.S. city.

The cars are greener over time, too, despite the more emissions-intensive battery manufacturing process. Dr. Trancik estimates that an electric vehicle’s production emissions would be offset in anywhere from six to 18 months, depending on how clean the energy grid is where the car is charging.

In some areas, EVs are even being used to power homes, enhancing their value as a sustainable investment. Recent EPA rules aim to boost EV sales, further signaling government support. California leads the nation in EV charging infrastructure, setting a model for nationwide adoption.

The new data showed hybrid cars, which run on a combination of fuel and battery power, and can sometimes be plugged in, had more mixed results for both emissions and costs. Some hybrids were cheaper and spewed less planet-warming carbon dioxide than regular cars, but others were in the same emissions and cost range as gas-only vehicles.

Traditional gas-burning cars were usually the least climate friendly option, though long-term costs and emissions spanned a wide range. Compact cars were usually cheaper and more efficient, while gas-powered SUVs and luxury sedans landed on the opposite end of the spectrum.

Dr. Trancik’s team released the data in an interactive online tool to help people quantify the true costs of their car-buying decisions — both for the planet and their budget. The new estimates update a study published in 2016 and add to a growing body of research underscoring the potential lifetime savings of electric cars.

Take the Tesla Model 3, the most popular electric car in the United States. The M.I.T. team estimated the lifetime cost of the most basic model as comparable to a Nissan Altima that sells for $11,000 less upfront. (That’s even though Tesla’s federal tax incentive for electric vehicles has ended.)

Toyota’s Hybrid RAV4 S.U.V. also ends up cheaper in the long run than a similar traditional RAV4, a national bestseller, despite a higher retail price.

Hawaii, Alaska and parts of New England have some of the highest average electricity costs, while parts of the Midwest, West and South tend to have lower rates. Gas prices are lower along the Gulf Coast and higher in California. But an analysis from the Union of Concerned Scientists still found that charging a vehicle was more cost effective than filling up at the pump across 50 major American cities. “We saw potential savings everywhere,” said David Reichmuth, a senior engineer for the group’s Clean Transportation Program.

Still, the upfront cost of an electric vehicle continues to be a barrier for many would-be owners.

The federal government offers a tax credit for some new electric vehicle purchases, but that does nothing to reduce the initial purchase price and does not apply to used cars. That means it disproportionately benefits wealthier Americans. Some states, like California, offer additional incentives. President-elect Joseph R. Biden Jr. has pledged to offer rebates that help consumers swap inefficient, old cars for cleaner new ones, and to create 500,000 more electric vehicle charging stations, too.

EV sales projections for 2024 suggest continued acceleration, especially as costs fall and policy support expands. Chris Gearhart, director of the Center for Integrated Mobility Sciences at the National Renewable Energy Laboratory, said electric cars will become more price competitive in coming years as battery prices drop. At the same time, new technologies to reduce exhaust emissions are making traditional cars more expensive. “With that trajectory, you can imagine that even immediately at the purchase price level, certain smaller sedans could reach purchase price parity in the next couple of years,” Dr. Gearhart said.

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.

Ford Oakville Electric Vehicle Complex will anchor EV production in Ontario, adding a battery plant, retooling lines, and assembly capacity for passenger models targeting the North American market and Canada's zero-emission mandates.

Key Points

A retooled Ontario hub for passenger EV production, featuring on-site battery assembly and modernized lines.

✅ Retooling begins Q2 2024; EV production slated for 2025.

✅ New 407,000 sq ft battery plant for pack assembly.

✅ First full-line passenger EV production in Canada.

Ford Motor Co. has revealed some details of its plan to spend $1.8 billion on its Oakville Assembly Complex to turn it into an electric vehicle production hub, a government-backed Oakville EV deal, in the latest commitment by an automaker transitioning towards an electric future.

The automaker said Tuesday that it will start retooling the Ontario complex in the second quarter of 2024, bolstering Ontario's EV jobs boom, and begin producing electric vehicles in 2025.

The transformation of the Oakville site, to be renamed the Oakville Electric Vehicle Complex, will include a new 407,000 square-foot battery plant, similar to Honda's Ontario battery investment efforts, where parts produced at Ford's U.S. operations will be assembled into battery packs.

General Motors is already producing electric delivery vans in Canada, and its Ontario EV plant plans continue to expand, but Ford says this is the first time a full-line automaker has announced plans to produce passenger EVs in Canada for the North American market.

GM said in February it plans to build motors for electric vehicles at its St. Catharines, Ont. propulsion plant, aligning with the Niagara Region battery investment now underway. The motors will go into its BrightDrop electric delivery vans, which it produces in part at its Ingersoll, Ont. plant, as well as its electric pickup trucks, producing enough at the plant for 400,000 vehicles a year.

Ford's announcement is the latest commitment by an automaker transitioning towards an electric future, part of Canada's EV assembly push that is accelerating.

"Canada and the Oakville complex will play a vital role in our Ford Plus transformation," said chief executive Jim Farley in a statement.

The company has committed to invest over US$50 billion in electric vehicles globally and has a target of producing two million EVs a year by the end of 2026 as part of its Ford Plus growth plan, reflecting an EV market inflection point worldwide.

Ford didn't specify in the release which models it planned to build at the Oakville complex, which currently produces the Ford Edge and Lincoln Nautilus.

The company's spending plans were first announced in 2020 as part of union negotiations, with workers seeking long-term production commitments and the Detroit Three automakers eventually agreeing to invest in Canadian operations in concert with spending agreements with the Ontario and federal governments.

The two governments agreed to provide $295 million each in funding to secure the Ford investment.

"The partnership between Ford and Canada helps to position us as a global leader in the EV supply chain for decades to come," said Industry Minister Francois-Philippe Champagne in Ford's news release.

Funding help comes as the federal government moves to require that at least 20 percent of new vehicles sold in Canada will be zero-emission by 2026, at least 60 per cent by 2030, and 100 per cent by 2035.
