Low-emissions sources are set to cover almost all the growth in global electricity demand in the next three years

Ontario EV Clean Electricity Plan aligns EV adoption with clean power, natural gas phaseout, and grid decarbonization, cutting greenhouse gas emissions. Parties propose net-zero by 2030 as IESO warns rising gas use undermines climate gains.

Key Points

A plan to link EV growth to a cleaner grid by phasing out gas, boosting renewables, and targeting net-zero power.

✅ Parties back EVs; most pledge gas phaseout by 2030

✅ IESO projects quadrupled grid emissions under more gas

✅ Clean power needed to maximize EV climate benefits

Ontario’s political leaders are unanimously promoting electric vehicles (EVs) in their election platforms, even as Ontario's EV charging network remains only partially complete by a recent deadline. But if the electricity that powers those vehicles continues to come from burning fossil fuels, the province won’t reap the full environmental benefit of EVs, the Ontario Clean Air Alliance says.

“If we’re going to get the maximum benefit of electric vehicles, we’ve got to have a clean electricity supply,” said Jack Gibbons, chair of the alliance.

The environmental advocacy group surveyed the province’s Progressive Conservative, Liberal, NDP and Green parties about where they stand on generating electricity from natural gas, a fossil fuel. Only three committed to phasing out Ontario’s gas plants, a step seen as essential for supporting Canada's EV goals over time.

The NDP promised an electricity grid with net-zero emissions by 2030, while federal targets like the 2035 EV sales mandate shape transport electrification as well. The Liberals pledged to bring electricity emissions "as close to zero as possible by 2030.” The Green Party plans to make Ontario’s electricity “emission-free as quickly as possible,” aiming for a gas phaseout by 2030. The Progressive Conservatives did not answer the survey and did not respond to requests for comment from Canada’s National Observer.

Affordability and reliability were the top concerns for all three parties that responded, including the cost of expanding EV charging stations across the province.

Ontario used to get 25 per cent of its electricity from coal-fired power plants, even as 2019 fossil-fuel electricity share remained significant nationwide. However, in 1997, Gibbons formed the alliance to campaign against coal, and the province’s last coal-fired plant closed in 2014, leaving Ontario with one of North America’s cleanest electricity systems. At the time, Gibbons said, transitioning to gas-fired electricity made sense.

Now, Doug Ford’s Progressive Conservatives plan to double-down on gas-fired electricity generation to meet future demand, despite a looming energy storage supply crunch that is reshaping planning. As a result, planet-warming greenhouse gas emissions from electricity generation will more than quadruple by 2030, according to Ontario’s Independent Electricity System Operator (IESO).

If that happens, Ontario will lose 30 per cent of the progress it made by phasing out coal.

“If you have an increasing percentage of your electricity generated with fossil fuels, that undermines the activities of a variety of sectors in the society,” said Peter Tabuns, NDP candidate for Toronto-Danforth and former NDP energy and climate critic. “Ford's position of not committing to greening the system undermines the goals.”

In 2020, the alliance spearheaded a campaign calling on the Ford government to phase out the province’s gas plants. Thirty-two municipalities supported the campaign, and in Northern Ontario, Sudbury eco groups say sustainability is key to the grid's future. Many cities have said they will not be able to meet their own goals to fight climate change unless Ontario stops using fossil fuels for 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."

EV Adoption Limits highlight that electric vehicles alone cannot meet emissions targets; life cycle assessment, carbon budgets, clean grids, public transit, and battery materials constraints demand broader decarbonization strategies, city redesign, and active travel.

Key Points

EV Adoption Limits show EVs alone cannot hit climate targets; modal shift, clean grids, and travel demand are essential.

✅ 350M EVs by 2050 still miss 2 C goals without major mode shift

✅ Grid demand rises 41%, requiring clean power and smart charging

✅ Battery materials constraints need recycling, supply diversification

Today there are more than seven million electric vehicles (EVs) in operation around the world, compared with only about 20,000 a decade ago. It’s a massive change – but according to a group of researchers at the University of Toronto’s Faculty of Applied Science & Engineering, it won’t be nearly enough to address the global climate crisis. 

“A lot of people think that a large-scale shift to EVs will mostly solve our climate problems in the passenger vehicle sector,” says Alexandre Milovanoff, a PhD student and lead author of a new paper published in Nature Climate Change. 

“I think a better way to look at it is this: EVs are necessary, but on their own, they are not sufficient.” 

Around the world, many governments are already going all-in on EVs. In Norway, for example, where EVs already account for half of new vehicle sales, the government has said it plans to eliminate sales of new internal combustion vehicles by 2025. The Netherlands aims to follow suit by 2030, with France and Canada's EV goals aiming to follow by 2040. Just last week, California announced plans to ban sales of new internal combustion vehicles by 2035.

Milovanoff and his supervisors in the department of civil and mineral engineering – Assistant Professor Daniel Posen and Professor Heather MacLean – are experts in life cycle assessment, which involves modelling the impacts of technological changes across a range of environmental factors. 

They decided to run a detailed analysis of what a large-scale shift to EVs would mean in terms of emissions and related impacts. As a test market, they chose the United States, which is second only to China in terms of passenger vehicle sales. 

“We picked the U.S. because they have large, heavy vehicles, as well as high vehicle ownership per capita and high rate of travel per capita,” says Milovanoff. “There is also lots of high-quality data available, so we felt it would give us the clearest answers.” 

The team built computer models to estimate how many electric vehicles would be needed to keep the increase in global average temperatures to less than 2 C above pre-industrial levels by the year 2100, a target often cited by climate researchers. 

“We came up with a novel method to convert this target into a carbon budget for U.S. passenger vehicles, and then determined how many EVs would be needed to stay within that budget,” says Posen. “It turns out to be a lot.” 

Based on the scenarios modelled by the team, the U.S. would need to have about 350 million EVs on the road by 2050 in order to meet the target emissions reductions. That works out to about 90 per cent of the total vehicles estimated to be in operation at that time. 

“To put that in perspective, right now the total proportion of EVs on the road in the U.S. is about 0.3 per cent,” says Milovanoff. 

“It’s true that sales are growing fast, but even the most optimistic projections of an electric-car revolution suggest that by 2050, the U.S. fleet will only be at about 50 per cent EVs.” 

The team says that, in addition to the barriers of consumer preferences for EV deployment, there are technological barriers such as the strain that EVs would place on the country’s electricity infrastructure, though proper grid management can ease integration. 

According to the paper, a fleet of 350 million EVs would increase annual electricity demand by 1,730 terawatt hours, or about 41 per cent of current levels. This would require massive investment in infrastructure and new power plants, some of which would almost certainly run on fossil fuels in some regions. 

The shift could also impact what’s known as the demand curve – the way that demand for electricity rises and falls at different times of day – which would make managing the national electrical grid more complex, though vehicle-to-grid strategies could help smooth peaks. Finally, there are technical challenges stemming from the supply of critical materials for batteries, including lithium, cobalt and manganese. 

The team concludes that getting to 90 per cent EV ownership by 2050 is an unrealistic scenario. Instead, what they recommend is a mix of policies, rather than relying solely on a 2035 EV sales mandate as a singular lever, including many designed to shift people out of personal passenger vehicles in favour of other modes of transportation. 

These could include massive investment in public transit – subways, commuter trains, buses – as well as the redesign of cities to allow for more trips to be taken via active modes such as bicycles or on foot. They could also include strategies such as telecommuting, a shift already spotlighted by the COVID-19 pandemic. 

“EVs really do reduce emissions, which are linked to fewer asthma-related ER visits in local studies, but they don’t get us out of having to do the things we already know we need to do,” says MacLean. “We need to rethink our behaviours, the design of our cities, and even aspects of our culture. Everybody has to take responsibility for this.” 

The research received support from the Hatch Graduate Scholarship for Sustainable Energy Research and the Natural Sciences and Engineering Research Council of Canada.

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.

Lithuania Wind Power Investment accelerates renewable energy expansion with utility-scale wind farms, solar power synergies, streamlined permits, and grid integration to cut imports, boost energy independence, and align with EU climate policy.

Key Points

Lithuania Wind Power Investment funds wind projects to raise capacity, cut imports, and secure energy independence.

✅ 700-1000 MW planned across three wind farms over 3 years

✅ Simplified permitting and faster grid connections under new policy

✅ Supports EU climate goals and Lithuania's 2030 energy independence

The current unstable geopolitical situation is accelerating the European Union countries' investment in renewable energy, including European wind power investments across the region. After Russia launched war against Ukraine, the EU countries began to actively address the issues of energy dependence.

For example, Lithuania, a country by the Baltic Sea, imports about two-thirds of its energy from foreign countries to meet its needs, while Germany's solar boost underscores the region's shift. Following the start of the Russian invasion in Ukraine, the Lithuanian Government urgently submitted amendments to the documents regulating the establishment of wind and solar power plants to the Parliament for consideration.

One of Lithuania's priority goals is to accelerate the construction and development of renewable energy parks so that the country will achieve full energy independence in the next eight years, by 2030, mirroring Ireland's green electricity target in the near term. Lithuania is able to produce the amount of electricity that meets the country's needs.

Ramūnas Karbauskis, the owner of Agrokoncernas Group, one of the largest companies operating in the agricultural sector in the Baltic States, has no doubt that now is the best time to invest in the development of wind power plants in Lithuania. The group plans to build three wind farms over the next three years to generate a total of about 700-1000 MW of energy, and comparable projects like Enel's 450 MW wind farm illustrate the scale achievable. With such capacity, more than half a million residential buildings can be supplied with electricity.

According to Alina Adomaitytė, Deputy General Director of Agrokoncernas Group, the company plans to invest 1-1.4 billion Euros in wind power plants in three different regions of Lithuania.

"Lithuania is changing its policy by simplifying the procedure for the construction and development of wind and solar parks. This means that their construction time will be significantly shorter, unlike markets facing renewables backlogs causing delays. At present, the technologies have improved so much that such projects pay off quickly in market conditions," explains Adomaitytė.

Agrokoncernas Group plans to build wind farms on its own lands. This has the advantage of allowing more flexibility in planning construction and meeting the requirements for such parks.

"Lithuania is a very promising country for wind parks. It is a land of plains, and the Baltic Sea provides constant and sufficient wind power, and lessons from UK offshore wind show the potential for coastal regions. So far, there are not many such parks in Lithuania, and need for them is very high in order to achieve the goals of national energy independence," says the owner of the group.

According to Adomaitytė, until now the Agrokoncernas Group companies have specialized in agriculture, but now is a particularly favorable time to enter new business areas.

"We are open to investors. One of the strategic goals of our group is to contribute to the green energy revolution in Lithuania, which is becoming a strategic goal of the entire European Union, as seen in rising solar adoption in Poland across the region."

In addition to wind farms, Agrokoncernas Group is planning the construction of the most modern deep grain processing plant in Europe. This project is managed by Agrokoncernas GDP, a subsidiary of the group. The deep grain processing plant in Lithuania is to be built by 2026. It will operate on the principle of circular production, meaning that the plant will be environmentally friendly and there will be no waste in the production process itself.

Whooping crane migration near wind turbines shows strong avoidance of stopover habitat within 5 km, reshaping Great Plains siting decisions, reducing collision risk, and altering routes across croplands, grasslands, and wetlands.

Key Points

It examines cranes avoiding stopovers within 5 km of turbines, reshaping habitat use and routing across the Great Plains.

✅ Cranes 20x likelier to rest >5 km from turbines.

✅ About 5% of high-quality stopover habitat is impacted.

✅ Findings guide wind farm siting across Great Plains wetlands.

As gatherings to observe whooping cranes join the ranks of online-only events this year, a new study offers insight into how the endangered bird is faring on a landscape increasingly dotted with wind turbines across regions. The paper, published this week in Ecological Applications, reports that whooping cranes migrating through the U.S. Great Plains avoid “rest stop” sites that are within 5 km of wind-energy infrastructure.

Avoidance of wind turbines can decrease collision mortality for birds, but can also make it more difficult and time-consuming for migrating flocks to find safe and suitable rest and refueling locations. The study’s insights into migratory behavior could improve future siting decisions as wind energy infrastructure continues to expand, despite pandemic-related investment risks for developers.

“In the past, federal agencies had thought of impacts related to wind energy primarily associated with collision risks,” said Aaron Pearse, the paper’s first author and a research wildlife biologist for the U.S. Geological Survey’s Northern Prairie Wildlife Research Center in Jamestown, N.D. “I think this research changes that paradigm to a greater focus on potential impacts to important migration habitats.”

Some policymakers have also rejected false health claims about wind turbines and cancer in public debate, underscoring the need for evidence-based decisions.

The study tracked whooping cranes migrating across the Great Plains, a region that encompasses a mosaic of croplands, grasslands and wetlands. The region has seen a rapid proliferation of wind energy infrastructure in recent years: in 2010, there were 2,215 wind towers within the whooping crane migration corridor that the study focused on; by 2016, when the study ended, there were 7,622 wind towers within the same area.

Pearse and his colleagues found that whooping cranes migrating across the study area in 2010 and 2016 were 20 times more likely to select “rest stop” locations at least 5 km away from wind turbines than those closer to turbines, a pattern with implications for developers as solar incentive changes reshape wind market dynamics according to industry analyses.

The authors estimated that 5% of high-quality stopover habitat in the study area was affected by presence of wind towers. Siting wind infrastructure outside of whooping cranes’ migration corridor would reduce the risk of further habitat loss not only for whooping cranes, but also for millions of other birds that use the same land for breeding, migration, and wintering habitat, and real-world siting controversies, such as an Alberta wind farm cancellation, illustrate how local factors shape outcomes for wildlife.
