France EV Bonus Eligibility Rules prioritize lifecycle carbon footprint, manufacturing emissions, battery sourcing, and transport impacts, reshaping electric car incentives and excluding many China-made EVs while aiming for WTO-compliant, low-emission industrial policy.

 

Key Points

France's EV bonus rules score lifecycle emissions to favor low-carbon models and limit incentives for China-made EVs.

✅ Scores energy, assembly, transport, and battery criteria

✅ Likely excludes China-made EVs with coal-heavy production

✅ Aims to align incentives with WTO-compliant climate goals

 

France has published new eligibility rules for electric car incentives to exclude EVs made in China, even though carmakers in Europe do not have more affordable rival models on the French market.


WHY IS FRANCE REVISING ITS EV BONUS ELIGIBILITY RULES?
The French government currently offers buyers a cash incentive of between 5,000 and 7,000 euros in cash for eligible models to get more electric cars on the road, at a total cost of 1 billion euros ($1.07 billion) per year.

However, in the absence of cheap European-made EVs, a third of all incentives are going to consumers buying EVs made in China, a French finance ministry source said. The trend has helped spur a Chinese EV push into Europe and a growing competitive gap with domestic producers.

The scheme will be revamped from Dec. 15 to take into account the carbon emitted in a model's manufacturing process.

President Emmanuel Macron and government ministers have made little secret that they want to make sure French state cash is not benefiting Chinese carmakers.


WHAT DO THE NEW RULES DO?
Under the new rules, car models will be scored against government-set thresholds for the amount of energy used to make their materials, in their assembly and transport to market, as well as what type of battery the vehicle has.

Because Chinese industry generally relies heavily on coal-generated electricity, the criteria are likely to put the bonus out of Chinese carmakers' reach.

The government, which is to publish in December the names of models meeting the new standards, says that the criteria are compliant with WTO rules because exemptions are allowed for health and environmental reasons, and similar Canada EV sales regulations are advancing as well.


WILL IT DO ANYTHING?
With Chinese cars estimated to cost 20% less than European-made competitors, the bonus could make a difference for vehicles with a price tag of less than 25,000 euros, amid an accelerating global transition to EVs that is reshaping price expectations.

But French car buyers will have to wait because Stellantis' (STLAM.MI) Slovakia-made e-C3 city car and Renault's (RENA.PA) France-made R5 are not due to hit the market until 2024.

Nonetheless, many EVs made in China will remain competitive even without the cash incentive, reflecting projections that within a decade many drivers could be in EVs.

With a starting price of 30,000 euros, SAIC group's (600104.SS) MG4 will be less expensive than Renault's equivalent Megane compact car, which starts at 38,000 euros - or 33,000 euros with a 5,000-euro incentive.

Since its 46,000-euro starting price is just below the 47,000-euro price threshold for the bonus, Tesla's (TSLA.O) Y model - one of the best selling electric vehicles in France - could in theory also be impacted by the new rules for vehicles made in China.

S&P Global Mobility analyst Lorraine Morard said that even if most Chinese cars are ineligible for the bonus they would probably get 7-8% of France's electric car market next year, even as the EU's EV share continues to rise, instead of 10% otherwise.

Will the next wave of Ontario's electric vehicles run on clean power?

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.

Opinion | Why Electric Mail Trucks Are the Way of the Future

USPS Electric Mail Trucks promise zero-emission delivery, lower lifecycle and maintenance costs, and cleaner air. Congressional funding in Build Back Better would modernize the EV fleet and expand charging infrastructure, improving public health nationwide.

 

Key Points

USPS Electric Mail Trucks are zero-emission delivery vehicles that cut costs, reduce pollution, and improve health.

✅ Lower lifetime fuel and maintenance costs vs gas trucks

✅ Cuts greenhouse gas and NOx emissions in communities

✅ Expands charging infrastructure via federal investments

 

The U.S. Postal Service faces serious challenges, with billions of dollars in annual losses and total mail volume continuing to decline. Meanwhile, Congress is constantly hamstringing the agency.

But now lawmakers have an opportunity to invest in the Postal Service in a way that would pay dividends for years to come: By electrifying the postal fleet.

Tucked inside the massive social spending and climate package lumbering through the Senate is money for new, cleaner postal delivery trucks. There’s a lot to like about electric postal trucks. They’d significantly improve Americans’ health while also slowing climate change. And it just makes sense for taxpayers over the long term; the Postal Service’s private sector competitors have already made similar investments, as EV adoption reaches an EV inflection point in the market. As Democrats weigh potential areas to cut in President Joe Biden’s Build Back Better plan, this is one provision that should escape the knife.

To call the U.S. Postal Service’s current vehicles “clunkers” would be an understatement. These often decades-old trucks are famous for having no airbags, no air conditioning and a nasty habit of catching fire. So the Postal Service’s recent decision to buy 165,000 replacement trucks is basically a no-brainer. But the main question is whether they will run on electricity or gasoline.

Electric vehicles are newer to the market and still carry a higher sticker price, as seen with electric bus adoption in many cities. But that higher price buys concrete benefits, like lower lifetime fuel and maintenance costs and huge reductions in pollution. Government demand for electric trucks will also push private markets to create better, cheaper vehicles, directly benefiting consumers. So while buying electric postal trucks may be somewhat more costly at first, over the long term, failing to do so could be far costlier.

At some level, this is a straightforward business decision that the Postal Service’s competitors have already made. For instance, Amazon has already deployed some of the 100,000 electric vans it recently ordered, and FedEx has promised a fully electric ground fleet by 2040, while nonprofit investment in electric trucks is accelerating electrification at major ports. In a couple of decades, the Postal Service could be the only carrier still driving dirty gas guzzlers, buying expensive fuel and paying the higher maintenance costs that combustion engines routinely require. Consumers could flock to greener competitors.

Beyond these business advantages, zero-emission vehicles carry other big benefits for the public. The Postal Service recently calculated some of these benefits by estimating the climate harms that going all-electric would avoid, benefits that persist even where electricity generation still includes fossil-generated electricity in nearby grids. Its findings were telling: A fully electric fleet would prevent millions or tens of millions of dollars’ worth of climate-change-related harms to property and human health each year of the trucks’ lifetimes (and this is probably a considerable underestimate). The world leaders that recently gathered at the global climate summit in Glasgow encouraged exactly this type of transition toward low-carbon technologies.

A cleaner postal fleet would benefit Americans in many other important ways. In addition to warming the planet, tailpipe pollutants can have dire health consequences for the people who breathe in the fumes. Mail trucks traverse virtually every neighborhood in the country and often must idle in residential areas, so we all benefit when they stop emitting. And these localized harms are not distributed equally. Some parts of the country — too often, low-income communities of color — already have poor air quality. Removing pollution from dirty mail trucks will especially help these overburdened and underserved populations.

The government’s purchasing power also routinely inspires companies to devise better and cheaper ways to do business. Investments in aerospace technologies, for instance, have spilled over into consumer innovations, giving us GPS technologies and faster, more fuel-efficient passenger jets. Bulk demand for cleaner trucks could inspire similar innovations as companies clamor for government contracts, meaning we all could get cheaper and better green products like car batteries, and the American EV boom could further accelerate those gains.

Additionally, because postal trucks are virtually everywhere in the country, if they go electric, that would mean more charging stations and grid updates everywhere too, and better utility planning for truck fleets to ensure reliable service. Suddenly, that long road trip that discourages many would-be electric car buyers may be simpler, which could boost electric vehicle adoption.

ENERGY

The case for electrifying the postal fleet is strong from both a business and a social standpoint. Indeed, even Postmaster General Louis DeJoy, who was appointed during the Trump administration, supports it. But getting there is not so simple. Most private businesses could just borrow the money they need for this investment and pay it back with the long-term savings they would enjoy. But not the Postal Service. Thanks to its byzantine funding structure, it cannot afford electric trucks’ upfront costs unless Congress either provides the money or lets it borrow more. This is the primary reason it has not committed to making more than 10 percent of its fleet electric.

And that returns us to the Build Back Better legislation. The version passed by the House sets aside $7 billion to help the Postal Service buy electric mail trucks — enough to electrify the vast majority of its fleet by the end of the decade.

Biden has made expanding the use of electric vehicles a top priority, setting an ambitious goal of 100 percent zero-emission federal vehicle acquisitions by 2035, and new EPA emission limits aim to accelerate EV adoption. But Sen. Joe Manchin has expressed resistance to some of the climate-related subsidies in the legislation and is also eager to keep costs down. This provision, however, is worthy of the West Virginia Democrat’s support.

Most Americans would see — and benefit from — these trucks on a daily basis. And for an operation that got its start under Benjamin Franklin, it’s a crucial way to keep the Postal Service relevant.

Canada set to hit 5 GW milestone

Canada Solar Capacity Outlook 2022-2050 projects 500 MW new PV in 2022 and 35 GW by 2050, driven by renewables policy, grid parity, NREL analysis, IEA-PVPS data, and competitive utility-scale photovoltaic costs.

 

Key Points

An evidence-based forecast of Canadian PV additions to 35 GW by 2050, reflecting policy, costs, and grid parity trends.

✅ 500 MW PV expected in 2022; cumulative capacity near 5 GW

✅ NREL outlook sees 35 GW by 2050 on cost competitiveness

✅ Policy shifts, ITCs, coal retirements accelerate solar uptake

 

Canada is set to install 500 MW of new solar in 2022, bringing its total capacity to about 5 GW, according to data from Canmet Energy, even as the Netherlands outpaces Canada in solar power generation. The country is expected to hit 35 GW of total solar capacity by 2050.

Canada’s cumulative solar capacity is set to hit 5 GW by the end of this year, according to figures from the federal government’s Canmet Energy lab. The country is expected to add around 500 MW of new solar capacity, from 944 MW last year, according to the International Energy Agency Photovoltaic Power Systems Programme (IEA-PVPS), which recently published a report on PV applications in Canada, even as solar demand lags in Canada.

“If we look at the recent averages, Canada has installed around 500 MW annually. I expect in 2022 it will be at least 500 MW,” said Yves Poissant, research manager at Canmet Energy. “Last year it was 944 MW, mainly because of a 465 MW centralized PV power plant installed in Alberta, where the Prairie Provinces are expected to lead national renewable growth.”

The US National Renewable Energy Laboratory (NREL) studied renewables integration and concluded that Canada’s cumulative solar capacity will increase sevenfold to 35 GW by 2050, driven by cost competitiveness and that zero-emissions by 2035 is achievable according to complementary studies.

Canada now produces 80% of its electricity from power sources other than oil. Hydroelectricity leads the mix at 60%, followed by nuclear at 15%, wind at 7%, gas and coal at 7%, and PV at just 1%. While the government aims to increase the share of green electricity to 90% by 2030 and 100% by 2050, zero-emission electricity by 2035 is considered practical and profitable, yet it has not set any specific goals for PV. Each Canadian province and territory is left to determine its own targets.

“Without comprehensive pan-Canadian policy framework with annual capacity targets, PV installation in the coming years will likely continue to be highly variable across the provinces and territories, especially after Ontario scrapped a clean energy program, which scaled back growth projections. Further policies mechanisms are needed to allow PV to reach its full potential,” the IEA-PVPS said.

Canada recently introduced investment tax credits for renewables to compete with the United States, but it is still far from being a solar powerhouse, with some experts calling it a solar laggard today. That said, the landscape has started to change in the past five years.

“Some laws have been put in place to retire coal plants by 2025. That led to new opportunities to install capacity,” said Poissant. “We expect the newly installed capacity will consist mostly of wind, but also solar.”

The cost of solar has become more competitive and the residential sector is now close to grid parity, according to Poissant. For utility-scale projects, old hydroelectric dams are still considerably cheaper than solar, but newly built installations are now more expensive than solar.

“Starting 2030, solar PV will be cost competitive compared to wind,” Poissant said.

Solar Is Now 33% Cheaper Than Gas Power in US, Guggenheim Says

US Renewable Energy Cost Advantage signals cheaper utility-scale solar and onshore wind versus natural gas, with LCOE declines, tax credits, and climate policy cutting electricity costs for utilities and grids across the United States.

 

Key Points

Cheaper solar and wind than natural gas, driven by LCOE drops, tax credits, and policy, lowering US electricity costs.

✅ Utility-scale solar is about one-third cheaper than gas

✅ Onshore wind costs roughly 44 percent less than natural gas

✅ Policy and tax credits accelerate renewables and cut power prices

 

Natural gas’s dominance as power-plant fuel in the US is fading fast as the cost of electricity generated by US wind and solar projects tumbles and as wind and solar surpass coal in the generation mix, according to Guggenheim Securities.

Utility-scale solar is now about a third cheaper than gas-fired power, while onshore wind is about 44% less expensive, Guggenheim analysts led by Shahriar Pourreza said Monday in a note to clients, a dynamic consistent with falling wholesale power prices in several markets today. 

“Solar and wind now present a deflationary opportunity for electric supply costs,” the analysts said, which “supports the case for economic deployment of renewables across the US,” as the country moves toward 30% wind and solar and one-fourth of total generation in the near term.

Gas prices have surged amid a global supply crunch after Russia’s invasion of Ukraine, while tax-credit extensions and sweeping US climate legislation have brought down the cost of wind and solar, even as renewables surpassed coal in 2022 nationwide. Renewables-heavy utilities like NextEra Energy Inc. and Allete Inc. stand to benefit, and companies that can boost spending on wind and solar, as wind, solar and batteries dominate the 2023 pipeline, will also see faster growth, Guggenheim said.

Netherlands' Renewables Drive Putting Pressure On Grid

The Netherlands grid crisis exposes how rapid renewable energy growth is straining transmission capacity. Solar, wind, and electric vehicle demand are overloading networks, forcing officials to urge reduced peak-time power use and accelerate national grid modernization plans.

 

Main Points

The Netherlands grid crisis refers to national electricity congestion caused by surging renewable energy generation and rising consumer demand.

✅ Grid congestion from rapid solar and wind expansion

✅ Strained transmission and distribution capacity

✅ National investment in smart grid upgrades

 

The Dutch government is urging households to reduce electricity consumption between 16:00 and 21:00 — a signal that the country’s once-stable power grid is under serious stress. The call comes amid an accelerating shift to wind and solar power that is overwhelming transmission infrastructure and creating “grid congestion” across regions, as seen in Nordic grid constraints this year.

In a government television campaign, a narrator warns: “When everyone uses electricity at the same time, our power grid can become overloaded. That could lead to failures — so please try to use less electricity between 4 pm and 9 pm.” The plea reflects a system where supply occasionally outpaces the grid’s ability to distribute it, with some regions abroad issuing summer blackout warnings already.

According to Dutch energy firm Eneco’s CEO, Kys-Jan Lamo, the root of the problem lies in the mismatch between modern renewable generation and a grid built for centralized fossil fuel plants. He notes that 70% of Eneco’s output already comes from solar and wind, and this “grid congestion is like traffic on the power lines.” Lamo explains:

“The grid congestion is caused by too much demand in some areas of the network, or by too much supply being pushed into the grid beyond what the network can carry.”

He adds that many of the transmission lines in residential areas are narrow — a legacy of when fewer and larger power plants fed electricity through major feeder lines, underscoring grid vulnerabilities seen elsewhere today. Under the new model, renewable generation occurs everywhere: “This means that electricity is now fed into the grid even in peripheral areas with relatively fine lines — and those lines cannot always cope.”

Experts warn that resolving these issues will demand years of planning and immense investment in smarter grid infrastructure over the coming years. Damien Ernst, an electrical engineering professor at Liège University and respected voice on European grids, states that the Netherlands is experiencing a “grid crisis” brought on by “insufficient investment in distribution and transmission networks.” He emphasizes that the speed of renewable deployment has outpaced the grid’s capacity to absorb it.

Eneco operates a “virtual power plant” control system — described by Lamo as “the brain we run” — that dynamically balances supply and demand. During periods of oversupply, the system can curtail wind turbines or shut down solar panels. Conversely, during peak demand, the system can throttle back electricity provision to participating customers in exchange for lower tariffs. However, these techniques only mitigate strain — they cannot replace the need for physical upgrades or bolster resilience to extreme weather outages alone.

The bottleneck has begun limiting new connections: “Consumers often want to install heat pumps or charge electric vehicles, but they increasingly find it difficult to get the necessary network capacity,” Lamo warns. Businesses too are struggling. “Companies often want to expand operations, but cannot get additional capacity from grid operators. Even new housing developments are affected, since there’s insufficient infrastructure to connect whole communities.”

Currently, thousands of businesses are queuing for network access. TenneT, the national grid operator, estimates that 8,000 firms await initial connection approval, and another 12,000 seek to increase their capacity allocations. Stakeholders warn that unresolved congestion risks choking economic growth.

According to Kys-Jan Lamo: “Looking back, almost all of this could have been prevented.” He acknowledges that post-2015 climate commitments placed heavy emphasis on adding generation and on grid modernization costs more broadly, but “we somewhat underestimated the impact on grid capacity.”

In response, the government has introduced a national “Grid Congestion Action Plan,” aiming to accelerate approvals for infrastructure expansions and to refine regulations to promote smarter grid use. At the same time, feed-in incentives for solar power are being scaled back in some regions, and certain areas may even impose charges to integrate new solar systems into the grid.

The scale of what’s needed is vast. TenneT has proposed adding roughly 100,000 km of new power lines by 2050 and investing in doubling or tripling existing capacity in many areas. However, permit processes can take eight years before construction begins, and many projects require an additional two years to complete. As Lamo points out, “the pace of energy transition far exceeds the grid’s existing capacity — and every new connection request simply extends waiting lists.”

Unless grid expansion keeps up, and as climate pressures intensify, the very clean energy future the Netherlands is striving for may remain constrained by the physics of distribution.

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."
