California Takes the Lead in Electric Vehicle and Charging Station Adoption

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."

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.

B.C. Hydro fast EV charging stations roll out 180 kW DC fast chargers, power sharing, and rural network expansion in Surrey, Manning Park, Mackenzie, and Tumbler Ridge to ease range anxiety across northern B.C.

Key Points

180 kW DC chargers with power sharing, expanding B.C.'s rural EV network to cut range anxiety and speed up recharging.

✅ 180 kW DC fast charging: ~180 km added in about 10 minutes

✅ Power sharing enables two vehicles to use one unit simultaneously

✅ Expands rural charging coverage to cut range anxiety for northern B.C.

B.C. Hydro has unveiled plans to install new charging stations it says can add as much as 180 kilometres worth of range to the average electric vehicle in 10 minutes.

The utility says the new 180-kilowatt units will be added to its network, expanding stations in southern B.C. as soon as this fall, with even more scheduled to arrive in 2024.

The first communities to get the new faster-charge stations are Surrey, Manning Park and, north of Prince George, Mackenzie and Tumbler Ridge, while the Lillooet fast-charging site is already operational.

B.C. Hydro president Chris O'Riley says both current and prospective electric vehicle owners have said they want improved coverage in more rural parts of the province in order to address range anxiety, as the utility has warned of a potential EV charging bottleneck if demand outpaces infrastructure.

"We are listening to feedback from our customers," he said.

The new stations will also be the first from B.C. Hydro to offer power sharing, which lets two different vehicles use the same unit to charge at the same time.

The adoption of electric vehicles in B.C. is much higher in southern urban areas than rural, northern ones, according to statistics from the provincial government made available in 2022, as the province leads the country in going electric according to recent reports.

The figures showed about one in every 45 people owns a zero-emission vehicle in the southwest regions of the province, but that number drops to one in 232 in the Kootenays, where the region makes electric cars a priority through local initiatives, and one in 414 in northern B.C.

The number of public charging stations closely corresponds to the number of zero-emission vehicles in various regions.

The Vancouver area has more than 500 fast-charging ports, according to ChargeHub, a website that tracks charging stations in North America. 

In contrast, the route from Prince George to Fort Nelson via Dawson Creek along Highway 97, part of the B.C. Electric Highway network connecting the region — a distance of more than 800 kilometres — has just three locations where a vehicle can be charged to 80 per cent power in an hour or less, creating challenges for people hoping to travel the route.

The disparity is also clear in a just-published analysis from the non-profit Community Energy Association, which acts as an advisory group to government associations. 

It found that while there is roughly one charging port every three square kilometres in Metro Vancouver, the number drops to one every 250 square kilometres in the Regional District of East Kootenay and one every 3,500 square kilometres in the Peace River Regional District, in the province's northeast.

"The more infrastructure we can get across the region ... the more the adoption of electric vehicles will increase," said the association's director of transportation initiatives, Danielle Weiss.

"We are excited to hear that B.C. Hydro is also viewing rural areas as a key focus for their new, enhanced charging technology."

B.C. Hydro says it currently has 153 charging units at 84 locations across the province with plans to add an additional 3,000 ports over the next 10 years, with provincial EV charger rebates supporting home and workplace installations as well.

Harbour Air Electric Seaplane completes a point-to-point test flight, showcasing electric aircraft innovation, zero-emission short-haul travel, H55 battery technology, and magniX propulsion between Vancouver and Victoria, advancing sustainable aviation and urban air mobility.

Key Points

Retrofitted DHC-2 Beaver testing zero-emission short-haul flights with H55 batteries and magniX propulsion.

✅ 74 km in 24 minutes, Vancouver to Victoria test route

✅ H55 battery pack and magniX electric motor integration

✅ Aims to certify short-haul, zero-emission commercial service

A seaplane airline in Vancouver says it has achieved a new goal in its development of an electric aircraft.

Harbour Air Seaplanes said in a release about its first electric passenger flights timeline that it completed its first direct point-to-point test flight on Wednesday by flying 74 kilometres in 24 minutes from a terminal on the Fraser River near Vancouver International Airport to a bay near Victoria International Airport.

"We're really excited about this project and what it means for us and what it means for the electric aviation revolution to be able to keep pushing that forward," said Erika Holtz, who leads the project for the company.

Harbour Air, founded in 1982, uses small propeller planes to fly commercial flights between the Lower Mainland, Seattle, Vancouver Island, the Gulf Islands and Whistler.

In the last few years it has turned its attention to becoming a leader in green urban mobility, as seen with electric ships on the B.C. coast, which would do away with the need to burn fossil fuels, a major contributor to climate change, for air travel.

In December 2019, a pilot flew one of Harbour Air's planes — a more than 60-year-old DHC-2 de Havilland Beaver floatplane that had been outfitted with a Seattle-based company's electric propulsion system, magniX — for three minutes over Richmond.

Since then, the company has continued to fine-tune the plane and conduct test flights in order to meet federally regulated criteria for Canada's first commercial electric flight, showing it can safely fly with passengers.

Harbour Air's new fully electric seaplane flew over the Fraser River for three minutes today in its debut test flight.
Holtz said flying point-to-point this week was a significant step forward.

"Having this electric aircraft be able to prove that it can do scheduled flights, it moves us that step closer to being able to completely convert our entire fleet to electric," she said.

All the test flights so far have been made with only a pilot on board.

Early in Harbour Air's undertaking to develop an all-electric airplane, experts who study the aviation sector said Harbour Air would have to find a way to make the plane light enough to carry heavy lithium batteries and passengers, without exceeding weight limits for the plane.

Werner Antweiler, a professor of economics at UBC's Sauder School of Business who studies the commercialization of novel technologies around mobility, said in 2021 that Harbour Air's challenge would be proving to regulators that the plane was safe to fly and the batteries powerful enough to complete short-haul flights with power to spare.

In April 2021 Harbour Air partnered with Swiss company H55 to incorporate its battery technology, reflecting ongoing research investment to limit weight and improve the distance the plane could fly.

Shawn Braiden, a vice-president with Harbour Air, said the company is trying to get as much power as possible from the lightest possible batteries, a challenge shared by BC Ferries' hybrid ships as well. 

"It's a balancing act," he said.

In December, Harbour Air announced it had begun work on converting a second de Havilland Beaver to an all-electric airplane, copying the original prototype.

The plan is to retrofit version two of the ePlane with room for a pilot plus three passengers. If certified for commercial use, it could become one of the first all-electric commercial passenger planes operating in the world.

Seth Wynes, a post-doctoral fellow at Concordia University who has studied how to de-carbonize the aviation industry, said Harbour Air's progress on its eplane project won't solve the pollution problem of long-haul flights, but could inspire other short-haul airlines to follow suit, alongside initiatives like electric ferries in B.C. that expand low-carbon transportation. 

"It's also just really helpful to pilot these technologies and get them going where they can be scaled up and used in a bunch of different places around the world," he said. "So that's why Harbour Air making progress on this front is exciting."

100% Renewable Energy Transition unites solar, wind, hydropower, geothermal, and bioenergy with storage, smart grids, and sector coupling, delivering decarbonization, energy security, and lower LCOE amid post-Fukushima policy shifts and climate resilience goals.

Key Points

It is a pathway using all renewables plus storage and grids to fully decarbonize power, heat, transport, and industry.

✅ Integrates solar, wind, hydro, geothermal, and bioenergy

✅ Uses storage, smart grids, and sector coupling for reliability

✅ Requires enabling policies, finance, and rapid deployment

Renewable energy organizations representing different spheres of the renewable energy community have gathered on the occasion of the tenth anniversary of the Great East Japan Earthquake and Fukushima nuclear accident to emphasize that renewable energies are not only available in abundance, with global renewable power on course to shatter more records, but ready to deliver a renewable world.

The combination of all renewable technologies, be it bioenergy, geothermal energy, hydropower, ocean energy, solar energy or wind power, in particular in combination with storage options, can satisfy all energy needs of mankind, be it for power, heating/cooling, transportation, or industrial processes.

Renewables have seen tremendous growth rates and cost reduction over the past two decades, but there are still many barriers that need to be addressed for a faster renewable energy deployment to eventually achieve global 100% renewable energy, as outlined in an on the road to 100% renewables initiative that charts the path. It is up to political decision-makers to create the legislative and regulatory conditions so that the renewable energy community can act as fast as needed.

Such rapid switch towards renewables is not only a must in light of nuclear risks and the growing threats of climate change, but also the necessary response to the current pandemic situation. And it will allow those hundreds of millions of humans in unserved areas to get for the first time ever access to modern energy services, as noted by a new IRENA report that details how renewables can decarbonise the energy sector and improve lives.

Speakers from the renewable energy community presented today in a joint webinar that a renewable future is a realistic vision, representing:

Energy Watch Group, Global100RE Platform, Global100RE Strategy Group, International Geothermal Association, ISEP Japan, REN Alliance, World Bioenergy Association, World Wind Energy Association.

Dr. Tetsunari Iida, Director of the Institute for Sustainable Energy Policies ISEP Japan:

Ten years ago, on 11 March 2021, the Great East Japan Earthquake and Fukushima Daiichi Nuclear Power Plant accident occurred. It is a "coincidence of global history" that it now coincides with the starting point of the 100% renewable energy initiative that is accelerating around the world.

The world has changed dramatically since 311. Germany, Italy, Switzerland, Taiwan, South Korea, China and many other countries were all shocked by 311 and shifted their focus from nuclear power to renewable energy, and in the U.S. clean energy industries are setting sights on market majority to accelerate this trend. The next ten years will be the decade in which this perception will rapidly become the "new reality". 311 was the "starting point" for a structural energy shift in world history.

Hans-Josef Fell, former MP, President of the Energy Watch Group and co-initiator of the Global100RE Strategy Group:

The disasters of Fukushima and Chernobyl are urging the entire world to quickly end the use of atomic energy, and many call for a fossil fuel lockdown to catalyze a climate revolution alongside the transition. Contrary to what is often claimed, nuclear energy cannot make a contribution to climate protection, but only creates immense problems with toxic radioactivity emissions, nuclear waste, atomic bomb material and the dangers of a nuclear catastrophe. In contrast, 100% renewable energies until 2030 can help achieve climate protection and a simultaneous nuclear phase-out, according to a recently published statement by a world-leading group of energy researchers from the USA, EU and Australia.

Their research suggests that a 100% renewable energy supply, including storage systems, can provide full energy security for all of mankind by 2030 and will even be cheaper than the existing nuclear and fossil energy supply, and with over 30% of global electricity already from renewables, momentum is strong. The only requirement for implementation is the right decisions taken by decision makers both in governments and industry. All technical and economic prerequisites for a disruptive conversion of the global energy supply to 100% renewable energies are already in place.

Hon. Peter Rae AO, President of WWEA and Honorary Chairman of the REN Alliance:

40 years ago, the idea of developing nuclear power appealed to me as a non-polluting method of generating electricity. So I studied it. How to deal with waste and how to ensure it would not create a danger to life. Along came Chernobyl and other accidents. Storage of waste was leaving dangerous hiding places while some waste was alleged to be dumped at sea. I became more and more concerned. There were demonstrations that the existing methods were dangerous and required very strict construction and operational tolerances - up went the cost. Long delays and huge cost increases. I had visited nuclear power stations and talked to expert proponents in UK, France, US, Taiwan and Australia, and debates such as New Zealand's electricity future reflect similar concerns. The more I did the more certain I became that it was not the way to go. Then Fukushima put the dangers and cost beyond doubt.

Let's get on with the rollover to renewables.

Dr. Marit Brommer, Executive Director of the International Geothermal Association IGA:

The IGA is proud to work with all renewable energy associations to continuously provide a unified voice to a cleaner energy future. The Geothermal sector is proven to be a partner of choice for many locations in the world serving baseload power and clean heat to customers. We are particularly interested in the increased attention system integration gets, which underpins the importance of all renewables coming together at events such as the webinar organised by the WWEA.

Christian Rakos, President of the World Bioenergy Association:

The IPCC has emphasized the important role of sustainable bioenergy for climate protection. Recent advances in technology allow us to use feedstock from forestry, wood processing and agricultural production in an efficient and clean way. Today, bioenergy already contributes 12 - 13% to global final energy demand. Importantly, contribution from bioenergy is more than 5 times as much as nuclear energy worldwide. Together with other renewable energy technologies such as solar, wind, geothermal and hydropower, bioenergy can increase the contribution in a substantial way to meet the energy demands of all end use sectors and meet the international energy and climate goals.

Stefan Gsanger, Secretary General of the World Wind Energy Association and Co-chair of the Global100RE Platform:

The switch to a renewable energy future requires new political and economic thinking: from centralised structures with few large actors towards decentralised, participatory models with millions of communities and citizens playing an active role, not only as consumers but also as producers of energy. To make this new paradigm the predominant energy paradigm is the true challenge of the energy transformation which we as the world community are facing. If we manage this shift well and on time, billions of people across the globe, in industrialised and developing countries alike, will benefit and will face a bright future.

GM Canada-Unifor EV Deal outlines a $1B plan to transform the CAMI plant in Ingersoll, Ontario, building BrightDrop EV600 delivery vans, boosting EV manufacturing, creating jobs, and securing future production with government-backed investment.

Key Points

A tentative $1B deal to retool CAMI for BrightDrop EV600 production, creating jobs and securing Canada's EV manufacturing.

✅ $1B to transform CAMI, Ingersoll, for BrightDrop EV600 vans

✅ Ratification vote set; Unifor Local 88 to review details

✅ Supports EV manufacturing, delivery logistics, and new jobs

GM Canada says it has reached a tentative deal with Unifor that if ratified will see it invest $1 billion to transform its CAMI plant in Ingersoll, Ont., to make commercial electric vehicles, aligning with GM's EV hiring plans across North America.

Unifor National President Jerry Dias says along with the significant investment the agreement will mean new products, new jobs amid Ontario's EV jobs boom and job security for workers.

Dias says in a statement that more details of the tentative deal will be presented to Unifor Local 88 members at an online ratification meeting scheduled for Sunday.

He says the results of the ratification vote are scheduled to be released on Monday.

Details of the agreement were not released Friday night.

A GM spokeswoman says in a statement that the plan is to build BrightDrop EV 600s -- an all-new GM business announced this week at the Consumer Electronics Show and part of EV assembly deals that put Canada in the race -- that will offer a cleaner way for delivery and logistics companies to move goods more efficiently.

Unifor said the contract, if ratified, will bring total investment negotiated by the union to nearly $6 billion after new agreements were ratified with General Motors, Ford, including Ford EV production plans, and Fiat Chrysler in 2020 that included support from the federal and Ontario governments, and parallel investments such as a Niagara Region battery plant bolstering the supply chain.

It said the Ford deal reached in September included $1.95 billion to bring battery electric vehicle production to Oakville via the Oakville EV deal and a new engine derivative to Windsor and the Fiat Chrysler agreement included more than $1.5 billion to build plug-in hybrid vehicles and battery electric vehicles.

Unifor said in November, General Motors agreed to a $1.3 billion dollar investment to bring 1,700 jobs to Oshawa, as Honda's Ontario battery investment signals wider sector momentum, plus more than $109 million to in-source new transmission work for the Corvette and support continued V8 engine production in St. Catharines.
