A variety of electric vehicles will hit the market this year, raising questions about the most critical element of any electric car: the battery.

How often do you have to replace the battery? Will it be recycled? Can you charge a battery even if it is not empty? How many charging cycles can the battery handle? Is it true there's a worldwide shortage of lithium?

Lithium-ion batteries can be found in all kinds of consumer products, from laptops to cell phones, and they also will be the power source in at least the first generation of electric cars. An electric-vehicle battery is basically just a cluster of thousands of cell phone batteries packaged together.

"If I want to buy an electric vehicle, I would want to know how many miles can I drive under real driving conditions, how long will my battery last and how long will the battery take to charge," said Venkat Srinivasan, a staff scientist at the Lawrence Berkeley National Laboratory in California.

The Chevrolet Volt and Nissan Leaf, the first mainstream plug-ins to reach the market, both offer battery warranties good for 100,000 miles or eight years. That will reassure many consumers, but there still are things they can do to maximize battery life and performance.

"Don't keep continuously fully charging and discharging them," Srinivasan said. "Pressing on the accelerator too much also draws power from the battery at a high rate, and can cause degradation."

Sunil M. Chhaya, an electric drive expert at the Electric Power Research Institute, notes that batteries age faster if the temperature of the battery is frequently elevated. The institute's research has found that heat management inside the batteries is the single most important predictor of battery health and longevity. That's one reason why Tesla uses a liquid cooling system to maximize the life of its battery packs.

"Batteries are like people and perform nicely when their operating temperature is in a 20-45 degrees Celsius or 68-113 degrees Fahrenheit window," Chhaya said. "Outside of it, they need to be 'thermally managed.'"

Even weather is a factor. In general, a cold battery exhibits higher resistance to current flow, meaning that the same amount of power at the wheels will produce much larger amounts of heat inside the battery due to internal power dissipation. This generates localized heat and, while it warms up the batteries, it also accelerates their aging process.

Consumers who live in colder climates are also likely to see reduced driving ranges because using the heater draws power - sometimes as much as 25 percent - from the battery.

And consumers eager to quickly charge a battery by using higher voltages need to be aware of the tradeoffs.

"Fast charging can degrade the battery life," said Mark Wagner, vice president of government relations at Johnson Controls, which manufactures lithium-ion batteries at its plant in Holland, Mich. "The vast majority of the vehicles will be charged up overnight at lower voltages, but if you charge very quickly, there can be mechanical stress on the battery."

But Mike Omotoso, an automotive analyst with J.D. Power and Associates, says there's no consensus about how much a battery is degraded by fast charging. And he notes that consumers rarely follow directions when it comes to battery use.

"If you think of your cell phone or laptop, you're supposed to charge the battery fully for 24 hours before using it the first time," Omotoso said. "But of course most of us are anxious to use something new right away, so we charge it for a couple of hours and then start using it. Then we complain that the battery life isn't as long as advertised."

Building begins on facility linking Canada hydropower to NYC

Champlain Hudson Power Express Converter Station brings Canadian hydropower via HVDC to Queens, converting 1,250 MW to AC for New York City's grid, replacing a retired fossil site with a zero-emission, grid-scale clean energy hub.

 

Key Points

A Queens converter turning 1,250 MW HVDC hydropower into AC for NYC's grid, repurposing an Astoria fossil site.

✅ 340-mile underwater/underground HVDC link from Quebec to Queens

✅ 1,250 MW DC-AC conversion feeding directly into NY grid by 2026

✅ Replaces Astoria oil site; supports NY's 70% renewables by 2030

 

New York Governor Kathy Hochul has announced the start of construction on the converter station of the Champlain Hudson Power Express transmission line, a project to bring electricity generated from Canadian hydropower to New York City.

The 340 mile (547 km) transmission line is a proposed underwater and underground high-voltage direct current power transmission line to deliver the power from Quebec, Canada, to Queens, New York City. The project is being developed by Montreal-based public utility Hydro-Quebec (QBEC.UL) and its U.S. partner Transmission Developers, while neighboring New Brunswick has signed NB Power deals to bring more Quebec electricity into the province.

The converter station for the line will be the first-ever transformation of a fossil fuel site into a grid-scale zero-emission facility in New York City, its backers say.

Workers have already removed six tanks that previously stored 12 million gallons (45.4 million liters) of heavy oil for burning in power plants and nearly four miles (6.44 km) of piping from the site in the Astoria, Queens neighborhood, echoing Hydro-Quebec's push to wean the province off fossil fuels as regional power systems decarbonize.

The facility is expected to begin operating in 2026, even as the Ontario-Quebec power deal was not renewed elsewhere in the region. Once the construction is completed, it will convert 1,250 megawatts of energy from direct current to alternating current power that will be fed directly into the state's power grid, helping address transmission constraints that have impeded incremental Quebec-to-U.S. power deliveries.

“Renewable energy plays a critical role in the transformation of our power grid while creating a cleaner environment for our future generations,” Hochul said. The converter station is a step towards New York’s target for 70% of the state’s electricity to come from renewable sources by 2030, as neighboring Quebec has closed the door on nuclear power and continues to lean on hydropower.

Seven small UK energy suppliers must pay renewables fees or risk losing licence

Ofgem Renewables Obligations drive supplier payments for renewables fees, feed-in tariffs, and renewable generation, with non-payment risking supply licences amid the price cap and volatile wholesale prices across the UK energy market.

 

Key Points

Mandatory payments by suppliers funding renewables via feed-in tariffs; non-payment can trigger supply licence revoking.

✅ Covers Renewables Obligation and Feed-in Tariff scheme compliance.

✅ Non-payment can lead to Ofgem action and licence loss.

✅ Affected by price cap and wholesale price volatility.

 

Seven small British energy suppliers owe a total of 34 million pounds ($43.74 million) in renewables fees, amid a renewables backlog that has stalled projects, and could face losing their supply licences if they cannot pay, energy regulator Ofgem reports.

Under Britain’s energy market rules, suppliers of energy must meet so-called renewables obligations and feed-in tariffs, including households' ability to sell solar power back to energy firms, which are imposed on them by the government to help fund renewable power generation.

Several small energy companies have gone bust over the past two years, a trend echoed by findings from a global utility study on renewable priorities, as they struggled to pay the renewables fees and as their profits were affected by a price cap on the most commonly used tariffs and fluctuating wholesale prices, even as a 10 GW contract brings new renewable capacity onto the UK grid.

Ofgem has called on the companies to make necessary payments by Oct. 31, as moves to offer community-generated power to all UK customers progress.

“If they do not pay Ofgem could start the process of revoking their licences to supply energy,” it said in a statement, as offshore wind power continues to scale nationwide.

The seven suppliers are, amid debates over clean energy impacts, Co-Operative Energy Limited; Flow Energy Limited; MA Energy Limited; Nabuh Energy Limited; Robin Hood Energy Limited; Symbio Energy Limited and Tonik Energy Limited. ($1 = 0.7773 pounds)

A New Electric Boat Club Launches in Seattle

Aurelia Boat Club delivers electric boat membership in Seattle, featuring zero-emission propulsion, quiet cruising, sustainable recreation, and a managed fleet with maintenance, insurance, moorage, and charging handled for members seeking hassle-free, eco-friendly boating.

 

Key Points

Aurelia Boat Club is a Seattle membership offering all-electric boats, with maintenance, insurance, and moorage included.

✅ Unlimited access to an all-electric fleet

✅ Maintenance, insurance, moorage, and charging included

✅ Quiet, zero-emission cruising on Seattle waters

 

Seattle's maritime scene has welcomed a new player: Aurelia Boat Club. Founded by former Pure Watercraft employees, Aurelia is poised to redefine electric boating in the city, where initiatives like Washington State Ferries hybrid-electric upgrade are underway. The club's inception follows the unexpected closure of Pure Watercraft, a Seattle-based startup that aimed to revolutionize the pleasure boating industry before its financial troubles led to its downfall.

From Pure Watercraft to Aurelia Boat Club

Pure Watercraft, established in 2011, garnered attention for its innovative electric propulsion systems designed to replace traditional gas-powered motors in boats, while efforts to build the first commercial electric speedboats also advanced. The company attracted significant investment, including a notable partnership with General Motors in 2021, which acquired a 25% stake in Pure Watercraft. Despite these efforts, Pure Watercraft faced financial difficulties and entered receivership in 2024, leading to the liquidation of its assets. 

Amidst this transition, Danylo Kurgan and Mrugesh Desai saw an opportunity to continue the vision of electric boating. Kurgan, formerly a financial analyst at Pure Watercraft and involved in the company's boat club operations, teamed up with Desai, a technology executive and startup investor. Together, they acquired key assets from Pure Watercraft's receivership, including electric outboard motors, pontoon boats, inflatable crafts, battery systems, spare parts, and digital infrastructure. 

Aurelia Boat Club's Offerings

Aurelia Boat Club aims to provide a sustainable and accessible alternative to traditional gas-powered boat clubs in Seattle. Members can enjoy unlimited access to a fleet of all-electric boats without the responsibilities of ownership. The club's boats are equipped with electric motors, offering a quiet and environmentally friendly boating experience, similar to how electric ships are clearing the air on the B.C. coast. Additionally, Aurelia handles maintenance, repairs, insurance, and moorage, allowing members to focus solely on enjoying their time on the water. 

The Future of Electric Boating in Seattle

Aurelia Boat Club's launch signifies a growing interest in sustainable boating practices in Seattle. The club's founders are committed to scaling the business and expanding their fleet to meet the increasing demand for eco-friendly recreational activities, as projects like battery-electric high-speed ferries indicate. By leveraging the assets and knowledge gained from Pure Watercraft, Aurelia aims to continue the legacy of innovation in the electric boating industry.

As the boating community becomes more environmentally conscious, initiatives like Aurelia Boat Club play a crucial role in promoting sustainable practices, and examples such as Harbour Air's electric aircraft highlight the momentum. The club's success could serve as a model for other cities, demonstrating that with the right vision and resources, the transition to electric boating is not only feasible but also desirable.

While the closure of Pure Watercraft marked the end of one chapter, it also paved the way for new ventures like Aurelia Boat Club to carry forward the mission of transforming the boating industry, with regional moves like the Kootenay Lake electric-ready ferry and international innovations such as Berlin electric flying ferry showing what's possible. With a strong foundation and a clear vision, Aurelia is set to make significant waves in Seattle's electric boating scene.

Elon Musk could help rebuild Puerto Rico with solar-powered electricity grid

Puerto Rico Tesla Solar Power enables resilient microgrids using batteries, renewable energy, and energy storage to rebuild the hurricane-damaged grid, reduce fossil fuels, cut costs, and accelerate recovery with scalable solar-plus-storage solutions.

 

Key Points

A solar-plus-storage plan using Tesla microgrids and batteries to restore Puerto Rico's cleaner, resilient power.

✅ Microgrids cut diesel reliance and harden critical facilities.

✅ Batteries stabilize the grid and shave peak demand costs.

✅ Scalable solar enables faster, modular disaster recovery.

 

Puerto Rico’s governor Ricardo Rossello has said that he will speak to Elon Musk after the Tesla inventor said his innovative solar and battery systems could be used to restore electricity on the island.

Mr Musk was mentioned in a tweet, referencing an article discussing ways to restore Puerto Rico’s power grid, which was knocked out by Hurricane Maria on September 20.

Restoring the ageing and already-weakened network has proved slow: as of Friday 90 per cent of the island remained without power. The island’s electricity company was declared bankrupt in July.

Mr Musk was asked: “Could @ElonMusk go in and rebuild #PuertoRico’s electricity system with independent solar & battery systems?”

The South African entrepreneur replied: “The Tesla team has done this for many smaller islands around the world, but there is no scalability limit, so it can be done for Puerto Rico too.

“Such a decision would be in the hands of the PR govt, PUC, any commercial stakeholders and, most importantly, the people of PR.”

His suggestion was seized upon by Mr Rossello, who then tweeted: “@ElonMusk Let's talk. Do you want to show the world the power and scalability of your #TeslaTechnologies?

“PR could be that flagship project.”

Mr Musk replied that he was happy to talk.

Restoring power to the battered island is a priority for the government, and improving grid resilience remains critical, with hospitals still running on generators and the 3.5 million people struggling with a lack of refrigeration or air conditioning.

Radios broadcast messages advising people how to keep their insulin cool, and doctors are concerned about people not being able to access dialysis.

And, with its power grid wiped out, the Caribbean island could totally rethink the way it meets its energy needs, drawing on examples like a resilient school microgrid built locally. 

“This is an opportunity to completely transform the way electricity is generated in Puerto Rico and the federal government should support this,” said Judith Enck, the former administrator for the region with the environmental protection agency.

“They need a clean energy renewables plan and not spending hurricane money propping up the old fossil fuel infrastructure.”

Forty-seven per cent of Puerto Rico’s power needs were met by burning oil last year - a very expensive and outdated method of electricity generation. For the US as a whole, petroleum accounted for just 0.3 per cent of all electricity generated in 2016 even as the grid isn’t yet running on 100% renewable energy nationwide.

The majority of the rest of Puerto Rico’s energy came courtesy of coal and natural gas, with renewables, which later faced pandemic-related setbacks, accounting for only two per cent of electricity generation.

“In that time of extreme petroleum prices, the utility was borrowing money and buying oil in order to keep those plants operating,” said Luis Martinez, a lawyer at natural resources defense council and former special aide to the president of Puerto Rico’s environmental quality board.

“That precipitated the bankruptcy that followed. It was in pretty poor shape before the storm. Once the storm got there, it finished the job.”

But Mr Martinez told the website Earther that it might be difficult to secure the financing for rebuilding Puerto Rico with renewables from FEMA (Federal Emergency Management Agency) funds.

“A lot of distribution lines were on wood poles,” he said.

“Concrete would make them more resistant to winds, but that would potentially not be authorized under the use of FEMA funds.

"We’re looking into if some of those requirements can be waived so rebuilding can be more resilient.”

Perry presses ahead on advanced nuclear reactors

Advanced Nuclear Reactors drive U.S. clean energy with small modular reactors, a new test facility at Idaho National Laboratory, and public-private partnerships accelerating nuclear innovation, safety, and cost reductions through DOE-backed programs and university simulators.

 

Key Points

Advanced nuclear reactors are next-gen designs, including SMRs, offering safer, cheaper, low-carbon power.

✅ DOE test facility at Idaho National Laboratory

✅ Small modular reactors with passive safety systems

✅ University simulators train next-gen nuclear operators

 

Energy Secretary Rick Perry is advancing plans to shift the United States towards next-gen nuclear power reactors.

The Energy Department announced this week it has launched a new test facility at the Idaho National Laboratory where private companies can work on advanced nuclear technologies, as the first new U.S. reactor in nearly seven years starts up, to avoid the high costs and waste and safety concerns facing traditional nuclear power plants.

“[The National Reactor Innovation Center] will enable the demonstration and deployment of advanced reactors that will define the future of nuclear energy,” Perry said.

With climate change concerns growing and net-zero emissions targets emerging, some Republicans and Democrats are arguing for the need for more nuclear reactors to feed the nation’s electricity demand. But despite nuclear plants’ absence of carbon emissions, the high cost of construction, questions around what to do with the spent nuclear rods and the possibility of meltdown have stymied efforts.

A new generation of firms, including Microsoft founder Bill Gates’ Terra Power venture, are working on developing smaller, less expensive reactors that do not carry a risk of meltdown.

“The U.S. is on the verge of commercializing groundbreaking nuclear innovation, and we must keep advancing the public-private partnerships needed to traverse the dreaded valley of death that all too often stifles progress,” said Rich Powell, executive director of ClearPath, a non-profit advocating for clean energy and green industrial strategies worldwide.

The new Idaho facility is budgeted at $5 million under next year’s federal budget, even as the cost of U.S. nuclear generation has fallen to a ten-year low, which remains under negotiation in Congress.

On Thursday another advanced nuclear developer working on small modular systems, Oregon-based NuScale Power, announced it was building three virtual nuclear control rooms at Texas A&M University, Oregon State University and the University of Idaho, with funding from the Energy Department.

The simulators will be open to researchers and students, to train on the operation of smaller, modular reactors, as well as the general public.

NuScale CEO John Hopkins said the simulators would “help ensure that we educate future generations about the important role nuclear power and small modular reactor technology will play in attaining a safe, clean and secure energy future for our country.”

California scorns fossil fuel but can't keep the lights on without it

California fossil fuel grid reliability plan addresses heat wave demand, rolling blackouts, and grid stability by temporarily procuring gas generation while accelerating renewables, storage, and transmission to meet clean energy and carbon-neutral targets by 2045.

 

Key Points

A stop-gap policy to prevent blackouts by buying fossil power while fast-tracking renewables, storage, and grid upgrades.

✅ Temporary procurement of gas to avoid rolling blackouts

✅ Accelerates renewables, storage, transmission permitting

✅ Aims for carbon neutrality by 2045 without new gas plants

 

California wants to quit fossil fuels. Just not yet Faced with a fragile electrical grid and the prospect of summertime blackouts, the state agreed to put aside hundreds of millions of dollars to buy power from fossil fuel plants that are scheduled to shut down as soon as next year.

That has prompted a backlash from environmental groups and lawmakers who say Democratic Gov. Gavin Newsom’s approach could end up extending the life of gas plants that have been on-track to close for more than a decade and could threaten the state’s goal to be carbon neutral by 2045.

“The emphasis that the governor has been making is ‘We’re going to be Climate Leaders; we’re going to do 100 percent clean energy; we’re going to lead the nation and the world,’” said V. John White, executive director of the Sacramento-based Center for Energy Efficiency and Renewable Technologies, a non-profit group of environmental advocates and clean energy companies. “Yet, at least a part of this plan means going the opposite direction.”

That plan was a last-minute addition to the state’s energy budget, which lawmakers in the Democratic-controlled Legislature reluctantly passed. Backers say it’s necessary to avoid the rolling blackouts like the state experienced during a heat wave in 2020. Critics see a muddled strategy on energy, and not what they expected from a nationally ambitious governor who has made climate action a centerpiece of his agenda.

The legislation, which some Democrats labeled as “lousy” and “crappy,” reflects the reality of climate change. Heat waves are already straining power capacity, and the transition to cleaner energy isn’t coming fast enough to meet immediate needs in the nation’s most populous state.

Officials have warned that outages would be possible this summer, as the grid faces heat wave tests again, with as many as 3.75 million California homes losing power in a worst-case scenario of a West-wide heat wave and insufficient electrical supplies, particularly in the evenings.

It’s also an acknowledgment of the political reality that blackout politics are hazardous to elected officials, even in a state dominated by one party.

Newsom emphasized that the money to prop up the power grid, part of a larger $4.3 billion energy spending package, is meant as a stop-gap measure. The bill allows the Department of Water Resources to spend $2.2 billion on “new emergency and temporary generators, new storage systems, clean generation projects, and funding on extension of existing generation operations, if any occur,” the governor said in a statement after signing the bill.

“Action is needed now to maintain reliable energy service as the State accelerates the transition to clean energy,” Newsom said.

Following the signing, the governor called for the state California Air Resources Board to add a set of ambitious goals to its 2022 Scoping Plan, which lays out California’s path for reducing carbon emissions.

Among Newsom’s requested changes is a move away from fossil fuels, asking state agencies to prepare for an energy transition that avoids the need for new natural gas plants.

Alex Stack, a spokesman for the governor, said in a statement that California has been a global leader in reducing pollution and exporting energy policies across Western states, and pointed to Newsom’s recent letter to the Air Resources Board as well as one sent to President Joe Biden outlining how states can work with the federal government to combat climate change.

“California took action to streamline permitting for clean energy projects to accelerate the build out of clean energy that is needed to meet our climate goals and help maintain reliability in the face of extreme heat, wildfires, and drought,” Stack said.

But the prospect of using state money on fossil fuel power, even in the short term, has raised ire among the state’s many environmental advocacy groups, and raised questions about whether California will be able to achieve its goals.

“What is so frustrating about an energy bill like this is that we are at crunch time to meet these goals,” said Mary Creasman, CEO of California Environmental Voters. “And we’re investing a scale of funding into things that exacerbate those goals.”

With climate change-induced drought and high temperatures continuing to ravage the West, California anticipates the demand on the grid will only continue to grow. Despite more than a decade of bold posturing and efforts to transition to solar, wind and hydropower, the state worries it doesn’t have enough renewable energy sources on hand to keep the power on in an emergency right now, amid a looming shortage that will test reliability.

The specter of power outages poses a hazard to Newsom, and Democrats in general, especially ahead of November. While the governor is widely expected to sail to reelection, rolling blackouts are a serious political liability — in 2003, they were the catalyst for recalling Democratic Gov. Gray Davis. A lack of power isn’t just about people sweating in the dark, said Steven Maviglio, a longtime Democratic consultant who served as communications director for Davis, it can affect businesses, travel and have an outsized impact on the economy.

It behooves any state official to keep the power on, but, unlike Davis, Newsom is under serious pressure to make sure the state also adheres to its climate goals.

“Gavin Newsom’s brand is based on climate change and clean air, so it’s a little more difficult for him to say ‘well that’s not as important as keeping the power on,’” Maviglio said.

The same bill effectively ends local government control over those projects, for the time being. It hopes to speed up the state’s production of renewable energy sources by giving exclusive authority over the siting of those projects to a single state agency for the next seven years.

Environmental advocates say the state is now scrambling to address an issue they’ve long known was coming. In 2010, California officials set a schedule to retire a number of coastal gas plants that rely on what’s known as once-through cooling systems, which are damaging to the environment, especially marine life, even as regulators weigh more power plants to maintain reliability today. Many of those plants have been retired since 2010, but others have received extensions.

The remaining plants have various deadlines for when they must cease operations, with the soonest being the end of 2023.

Also at issue is the embattled Diablo Canyon nuclear power plant, California’s largest electricity source. The Pacific Gas & Electric-owned plant is scheduled to close in 2025, but the strain on the grid has officials considering the possibility of seeking an extension. Newsom said earlier this spring he would be open to extending the life of the plant. Doing so would also require federal approval.

The International Brotherhood of Electrical Workers 1245, a labor union, sees the energy package as a way to preserve Diablo Canyon, and jobs at the plant.

“The value to 1245 PG&E members at Diablo Canyon is clear — funding to keep the plant open,” the union said of the bill.

Assemblymember Al Muratsuchi (D-Los Angeles) criticized the bill as “crappy” when it came to the floor in late June, describing it as “a rushed, unvetted and fossil-fuel-heavy response” to the state’s need to bolster the grid.

“The state has had over 12 years to procure and bring online renewable energy generation to replace these once through cooling gas power plants,” Muratsuchi said. “Yet, the state has reneged on its promise to shut down these plants, not once, but twice already.”

Not all details of the state’s energy budget are final. Lawmakers still have $3.8 billion to allocate when they return on Aug. 1 for the final stretch of the year.

Creasman, at California Environmental Voters, said she wants lawmakers to set specific guidelines for how and where it will spend the $2.2 billion when they return in August to dole out the remaining money in the budget. Newsom and legislators also need to ensure that this is the last time California has to spend money on fossil fuel, she said.

“Californians deserve to see what the plan is to make sure we’re not in this position again of having to choose between making climate impacts worse or keeping our lights on,” Creasman said. “That’s a false choice.”
