Tesla prepares to bring its electric cars to South America

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."

Maxeon IBC Solar Factory USA will scale clean energy with high-efficiency interdigitated back contact panels, DOE-backed manufacturing in Albuquerque, utility-scale supply, domestic production, 3 GW capacity, reduced imports, carbon-free electricity leadership.

Key Points

DOE-backed Albuquerque plant making high-efficiency IBC panels, 3 GW yearly, for utility-scale, domestic solar supply.

✅ 3 GW annual capacity; up to 8 million panels produced

✅ IBC cell efficiency up to 24.7% for utility-scale projects

✅ Reduces U.S. reliance on imported panels via domestic manufacturing

Solar energy stands as a formidable source of carbon-free electricity, with the No. 3 renewable source in the U.S. offering a clean alternative to traditional power generation methods reliant on polluting fuels. Advancements in solar technology continue to emerge, with a U.S.-based company poised to spearhead progress from a cutting-edge factory in New Mexico.

Maxeon, initially hailing from Silicon Valley in the 1980s, recently ventured into independence after separating from its parent company, SunPower, in 2020. Over the past few years, Maxeon has been manufacturing solar panels in Mexico, Malaysia, and the Philippines, as record U.S. panel shipments underscored rising demand.

Now, with backing from the U.S. Department of Energy's Loans Programs Office, Maxeon is preparing to commence construction on a new facility in Albuquerque in 2024, amid unprecedented growth in solar and storage nationwide. This state-of-the-art factory aims to produce up to 8 million panels annually, featuring the company's interdigitated back contact (IBC) technology, which has the capacity to generate three gigawatts of power each year. Notably, the entire U.S. solar industry completed five gigawatts of panels in 2022, making Maxeon's endeavor particularly ambitious and aligned with Biden's proposed tenfold increase in solar power goals.

Maxeon's presence in the United States holds the potential to reduce the country's reliance on imported panels, particularly from China. The primary focus will be on providing this advanced technology for utility departments, where pairing with increasingly affordable batteries can enhance grid reliability while shifting away from residential and commercial rooftops.

Maxeon has achieved a remarkable milestone in solar efficiency, with its latest IBC technology boasting an efficiency rating of 24.7%, as reported by PV Magazine.

This strategic move to the United States could be a game-changer, not only for Maxeon's success but also for clean power generation in a nation that has traditionally depended on external sources for its supply of solar panels, as energy-hungry Europe turns to U.S. solar equipment makers for solutions. Matt Dawson, Maxeon's Chief Technology Officer, emphasized the importance of achieving the lowest levelized cost of electricity with the lowest overall capital, a feat that China has accomplished in recent years due to the strength of its supply chain. As energy independence becomes a global concern, solar manufacturing is poised to expand beyond China, with Southeast Asia already showing signs of growth, and now the United States and possibly Europe, including Germany's solar boost during the energy crisis, following suit.

Ukraine Wind Energy Resilience shields the grid with wind power along the Black Sea, dispersing turbines to withstand missile attacks, accelerate clean energy transition, aid EU integration, and strengthen energy security and rapid recovery.

Key Points

A strategy in Ukraine using wind farms to harden the grid, ensure clean power, and speed recovery from missile strikes.

✅ Distributed turbines reduce single-point-of-failure risk

✅ Faster repair of substations and lines than power plants

✅ Supports EU-aligned clean energy and grid security goals

The giants catch the wind with their huge arms, helping to keep the lights on in Ukraine — newly built windmills, on plains along the Black Sea.

In 15 months of war, Russia has launched countless missiles and exploding drones at power plants, hydroelectric dams and substations, trying to black out as much of Ukraine as it can, as often as it can, even amid talk of limiting attacks on energy sites that has surfaced, in its campaign to pound the country into submission.

The new Tyligulska wind farm stands only a few dozen miles from Russian artillery, but Ukrainians say it has a crucial advantage over most of the country’s grid, helping stabilize the system even as electricity exports have occasionally resumed under fire.

A single, well-placed missile can damage a power plant severely enough to take it out of action, but Ukrainian officials say that doing the same to a set of windmills — each one tens of meters apart from any other — would require dozens of missiles. A wind farm can be temporarily disabled by striking a transformer substation or transmission lines, but these are much easier to repair than power plants.

“It is our response to Russians,” said Maksym Timchenko, CEO of DTEK Group, the company that built the turbines in the southern Mykolaiv region — the first phase of what is planned as Eastern Europe’s largest wind farm. “It is the most profitable and, as we know now, most secure form of energy.”

Ukraine has had laws in place since 2014 to promote a transition to renewable energy, both to lower dependence on Russian energy imports, with periods when electricity exports resumed to neighbors, and because it was profitable. But that transition still has a long way to go, and the war makes its prospects, like everything else about Ukraine’s future, murky.

In 2020, 12% of Ukraine’s electricity came from renewable sources — barely half the percentage for the European Union. Plans for the Tyligulska project call for 85 turbines producing up to 500 megawatts of electricity. That’s enough for 500,000 apartments — an impressive output for a wind farm, but less than 1% of the country’s prewar generating capacity.

After the Kremlin began its full-scale invasion of Ukraine in February 2022, the need for new power sources became acute, prompting deliveries such as a mobile gas turbine power plant to bolster capacity. Russia has bombarded Ukraine’s power plants and cut off delivery of the natural gas that fueled some of them.

Russian occupation forces have seized a large part of the country’s power supply, and Russia has built power lines to reactivate the Zaporizhzhia plant in occupied territory, ensuring that its output does not reach territory still held by Ukraine. They hold the single largest generator, the 5,700-megawatt Zaporizhzhia Nuclear Power Plant, which has been damaged repeatedly in fighting and has stopped transmitting energy to the grid, with UN inspectors warning of mines at the site during recent visits. They also control 90% of Ukraine’s renewable energy plants, which are concentrated in the southeast.

The postwar recovery plans Ukraine has presented to supporters including the European Union, which it hopes to join, feature a major new commitment to clean energy, even as a controversial proposal on Ukraine’s nuclear plants continues to stir debate.

Oxford Battery Energy Storage Project will store surplus renewable power near South-West Oxford and Woodstock, improving grid stability, peak shaving, and reliability, pending IESO approval and Hydro One transmission interconnection in Ontario.

Key Points

A Boralex battery project in South-West Oxford storing surplus power for Woodstock at peak demand pending IESO approval.

✅ 2028 commercial operation target

✅ Connects to Hydro One transmission line

✅ Peak shaving to stabilize grid costs

A Quebec-based renewable energy company is proposing to build a battery energy storage system in Oxford County near Woodstock.

The Oxford battery energy storage project put forward by Boralex Inc., if granted approval, would be ready for commercial operation in 2028. The facility would be in the Township of South-West Oxford, but also would serve Woodstock businesses and residences, supported by provincial disconnect moratoriums for customers, due to the city’s proximity to the site.

Battery storage systems charge when energy sources produce more energy than customers need, and, complementing Ontario’s energy-efficiency programs across the province, discharge during peak demand to provide a reliable, steady supply of energy.

Darren Suarez, Boralex’s vice-president of public affairs and communications in North America, said, “The system we’re talking about is a very large battery that will help at times when the electric grid has too much energy on the system. We’ll be able to charge our batteries, and when there’s a need, we can discharge the batteries to match the needs of the electric grid.”

South-West Oxford is a region Boralex has pinpointed for a battery storage project. “We look at grid needs as a whole, and where there is a need for battery storage, and we’ve identified this location as being a real positive for the grid, to help with its stability, a priority underscored by the province’s nuclear alert investigation and public safety focus,” Suarez said.

Suarez could not provide an estimated cost for the proposed facility but said the project would add about 75 jobs during the construction phase, in a sector where the OPG credit rating remains stable. Once the site is operational, only one or two employees will be necessary to maintain the facility, he said.

Boralex requires approval from the Independent Electricity System Operator (IESO), the corporation that co-ordinates and integrates Ontario’s electricity system operations across the province, for the Oxford battery energy storage project.

Upon approval, the project will connect with an existing Hydro One transmission line located north of the proposed site. “[Hydro One] has a process to review the project and review the location and ensure we are following safety standards and protocols in terms of integrating the project into the grid, with broader policy considerations like Ottawa’s hydro heritage also in view, but they are not directly involved in the development of the project itself,” Suarez said.

The proposal has been presented to South-West Oxford council. South-West Oxford Mayor David Mayberry said, “(Council) is still waiting to see what permits are necessary to be addressed if the proposal moves forward.”

Mayberry said the Ministry of Natural Resources and Forestry also would be reviewing the proposed project.

Thornton Sand and Gravel, the location of the proposed facility, was viewed positively by Mayberry. “From a positive perspective, they’re not using farmland. There is a plus we’re not using farmland, but there is concern something could leak into the aquifer. These questions need to be answered before it can be to the satisfaction of the community,” Mayberry said.

An open house was held on Sept. 14 to provide information to residents. Suarez said about 50 people showed up and the response was positive. “Many people came out to see what we planned for the project and there was a lot of support for the location because of where it actually is, and how it integrates into the community. It’s considered good use of the land by many of the people that were able to join us on that day,” Suarez said.

The Quebec-based energy company has been operating in Ontario for nearly 15 years and has wind farms in the Niagara and Chatham-Kent regions.

Boralex also is involved in two other battery storage projects in Ontario. The Hagersville project is a 40-minute drive northwest of Hamilton, and the other is in Tilbury, a community in Chatham-Kent. Commercial operation for both sites is planned to begin in 2025.

South-West Oxford and Woodstock will see some financial benefits from the energy storage system, Suarez said.

“It will help to stabilize energy costs. It will contribute to really shaving the most expensive energy on the system off the system. They’re going to take electricity when it’s the least costly, taking advantage of Ontario’s ultra-low overnight pricing options and utilize that least costly energy and displace the most costly energy.”

Tesla Battery Day Innovations detail larger cylindrical EV cells with higher energy density, greater power, longer range, cobalt-free chemistry, automated manufacturing, battery recycling, and lower cost per kWh to enable an affordable electric car.

Key Points

Tesla Battery Day innovations are new EV cells and methods to cut costs, extend range, and scale production.

✅ Larger cylindrical cells: 5x energy, 6x power, 16% more range

✅ Automation and recycling to cut battery cost per kWh

✅ Near-zero cobalt chemistry, in-house cell factories worldwide

Elon Musk described a new generation of electric vehicle batteries that will be more powerful, longer lasting, and half as expensive as the company’s current cells at Tesla’s “Battery Day”.

Tesla’s new larger cylindrical cells will provide five times more energy, six times more power and 16% greater driving range, Musk said, adding that full production is about three years away.

“We do not have an affordable car. That’s something we will have in the future. But we’ve got to get the cost of batteries down,” Musk said.

To help reduce cost, Musk said Tesla planned to recycle battery cells at its Nevada “gigafactory,” while reducing cobalt – one of the most expensive battery materials – to virtually zero. It also plans to manufacture its own battery cells at several highly automated factories around the world.

The automaker plans to produce the new cells via a highly automated, continuous-motion assembly process, according to Drew Baglino, Tesla senior vice-president of powertrain and energy engineering, a contrast with GM and Ford battery strategies in the broader market today.

Speaking at the event, during which Musk outlined plans to cut costs and reiterated a huge future for Tesla's energy business during the presentation, the CEO acknowledged that Tesla does not have its new battery design and manufacturing process fully complete.

The automaker’s shares slipped as Musk forecast the change could take three years. Tesla has frequently missed production targets.

Tesla expects to eventually be able to build as many as 20m electric vehicles a year, aligning with within-a-decade EV adoption outlooks cited by analysts. This year, the entire auto industry expects to deliver 80m cars globally.

At the opening of the event, which drew over 270,000 online viewers, Musk walked on stage as about 240 shareholders – each sitting in a Tesla Model 3 in the company parking lot – honked their car horns in approval.

As automakers shift from horsepower to kilowatts to comply with stricter environmental regulations amid an age of electric cars that appears ahead of schedule, investors are looking for evidence that Tesla can increase its lead in electrification technology over legacy automakers who generate most of their sales and profits from combustion-engine vehicles.

While average electric vehicle prices have decreased in recent years thanks to changes in battery composition and evidence that they are better for the planet and household budgets, they are still more expensive than conventional cars, with the battery estimated to make up a quarter to a third of an electric vehicle’s cost.

Some researchers estimate that price parity, or the point at which electric vehicles are equal in value to internal combustion cars, is reached when battery packs cost $100 per kilowatt hour (kWh), a potential inflection point for mass adoption.

Tesla’s battery packs cost $156 per kWh in 2019, according to electric vehicle consulting firm Cairn Energy Research Advisors, with some studies noting that EVs save money over time for consumers, which would put the cost of a 90-kWh pack at around $14,000.

Tesla is also building its own cell manufacturing facility at its new factory in Germany in addition to the new plant in Fremont.

Labrador EV Charging Infrastructure faces gaps, with few fast chargers; Level 2 dominates, fueling range anxiety for Tesla and Chevrolet Bolt drivers, despite rebates and Newfoundland's network linking St. John's to Port aux Basques.

Key Points

It refers to the current and planned network of Level 2 and Level 3 charging sites across Labrador.

✅ 2 public Level 2 chargers: Happy Valley-Goose Bay and Churchill Falls

✅ Phase 2: 3 fast chargers planned for HV-GB, Churchill Falls, Labrador City

✅ $2,500 rebates offered; rural range anxiety still deters buyers

Retired pilot Allan Carlson is used to crossing Labrador by air.

But he recently traversed the Big Land in an entirely new way, driving for hours on end in his electric car.

The vehicle in question is a Tesla Model S P100D, which Carlson says he can drive up to 500 kilometres on a full charge — and sometimes even a little more.

After catching a ferry to Blanc-Sablon, Que., earlier this month, he managed to reach Happy Valley-Goose Bay, over 600 kilometres away.

To get there, though, he had to use the public charging station in Blanc-Sablon. He also had to push the limits of what his car could muster. 

But more affordable mass-market electric vehicles don't have the battery power of a top-of-the-range Tesla, prompting the Big Land's first EV owner to wonder when Labrador infrastructure will catch up to the high-speed charging network recently unveiled across Newfoundland this summer.

Phillip Rideout, an electrician who lives in Nain, bought a Chevrolet Bolt EV for his son — the range of which tops out at under 350 kilometres, depending on driving patterns and weather conditions.

He's comfortable driving the car within Nain but said he's concerned about traveling to southern Labrador on a single charge.

"It's a start in getting these 14 charging stations across the island," Rideout said of Newfoundland's new network, "but there is still more work to be done."

The provincial government continues to push an electric-vehicle future, however, even as energy efficiency rankings trail the national average, despite Labradorians like Rideout feeling left out of the loop.

Bernard Davis, minister of environment and climate change, earlier this month announced that government is accepting applications for its electric-vehicle rebate program, as the N.W.T. EV initiative pursues similar goals.

Under the $500,000 program, anyone looking to buy a new or used EV would be entitled to $2,500 in rebates, an attempt by the provincial government to increase EV adoption.

But according to a survey conducted this year by polling firm Leger for the Canadian Vehicle Manufacturer's Association, 51 per cent of rural Canadians found a lack of fast-charging public infrastructure to be a major deterrent to buying an electric car, even as Atlantic EV interest lags overall, according to recent data.

While Newfoundland's 14-charger network, operated by N.L. Hydro and Newfoundland Power, allows drivers to travel from St. John's to Port aux Basques, and 10 new fast-charging stations are planned along the Trans-Canada in New Brunswick, Labrador in contrast has just two publicly available charging locations: one at the YMCA in Happy Valley-Goose Bay and the other near the town office of Churchill Falls.

This is the proposed second phase of additional Level 2 and Level 3 charging locations across Labrador. (TakeChargeNL)
These are slower, Level 2 chargers, as opposed to newer Level 3 charging stations on the island. A Level 2 system averages 50 kilometres of range per hour, and a Level 3 systems can add up to 250 kilometres within the same time frame, making them about five times faster.

Even though all of the fast-charging stations have gone to Newfoundland, MHA for Lake Melville Perry Trimper is optimistic about Labrador's electric future.

Trimper has owned an EV in St. Johns since 2016, but told CBC he'd be comfortable driving it in Happy Valley-Goose Bay.

He acknowledged, however, that prospective owners in Labrador might not be able to drive far from their home charging outlet. 

More promises
If rural skepticism driven by poor infrastructure continues, the urban population could lead the way in adoption, allowing the new subsidies to disproportionately go toward larger population centres, Davis acknowledged.

"Obviously people are not going to purchase electric vehicles if they don't believe they can charge them where they want to be or where they want to go," Davis said in an interview in early September.

Under the provincial government's Phase 2 proposal, Newfoundland and Labrador is projected to get 19 charging stations, with three going to Labrador in Happy Valley-Goose Bay, Churchill Falls and Labrador City, taking cues from NB Power's public network in building regional coverage.

Davis would not commit to a specific cutoff period for the rebate program or a timeline for the first fast-charging stations in Labrador to be built.

"At some point, we are not going to need to place any subsidy on electric vehicles," he said, "but that time is not today and that's why these subsidies are important right now."

Future demand 
Goose Bay Motors manager Joel Hamlen thinks drivers in Labrador could shift away from gas vehicles eventually, even as EV shortages and wait times persist.

But he says it'll take investment into a charging network to get there.

"If we can get something set up where these people can travel down the roads and use these vehicles in the province … I am sure there will be even more of a demand," Hamlen said.
