Pyroelectric Energy Harvesting captures low-grade heat via thin-film materials, converting temperature fluctuations into power for waste heat recovery in electronics, vehicles, and industrial machinery, offering a thermoelectric alternative for microelectronics and exascale systems.

 

Key Points

Thin-film pyroelectric harvesting turns temperature changes into electricity, enabling low-grade waste heat recovery.

✅ Converts low-grade heat fluctuations into usable power

✅ Thin-film design suits microelectronics and edge devices

✅ Alternative to thermoelectrics for waste heat recovery

 

The electronic device you are reading this on is currently producing a modest to significant amount of waste heat that emerging thermoelectric materials could help recover in principle. In fact, nearly 70% of the energy produced annually in the US is ultimately wasted as heat, much of it less than 100 degrees Celsius. The main culprits are computers and other electronic devices, vehicles, as well as industrial machinery. Heat waste is also a big problem for supercomputers, because as more circuitry is condensed into smaller and smaller areas, the hotter those microcircuits get.

It’s also been estimated that a single next-generation exascale supercomputer could feasibly use up to 10% of the energy output of just one coal-fired power station, and that nearly all of that energy would ultimately be wasted as heat.

What if it were possible to convert that heat energy into a useable energy source, and even to generate electricity at night from temperature differences as well?

#google#

It’s not a new idea, of course. In fact the possibility of thermoelectric energy generation, where thermal energy is turned into electricity was recognised as early as 1821, around the same time that Michael Faraday developed the electric motor.

Unfortunately, when the heat source is ‘low grade’, aka less than 100 degrees Celsius, a number of limitations arise, and related approaches for nighttime renewable generation face similar challenges as well. For it to work well, you need materials that have quite high electrical conductivity, but low thermal conductivity. It’s not an easy combination to come by.

Taking a different approach, researchers at the University of California, Berkeley, have developed thin-film that uses pyroelectric harvesting to capture heat-waste and convert heat to electricity in prototype demonstrations. The findings were published today in Nature Materials.

✅ 300 hires to scale offshore wind blade production

✅ 6-week Center of Excellence training for all recruits

✅ Second 107-meter blade mold boosts capacity

 

GE Renewable Energy plans to recruit 300 employees in 2021 at its LM Wind Power wind turbine blade factory in Cherbourg, France / Opened almost three years ago in April 2018, the factory today counts more than 450 employees / Every new hire will go through an intensive training program at the factory's ‘Center of Excellence' to learn wind turbine blade manufacturing processes / Site has produced the first offshore wind turbine blade longer than 100 meters, 107-meters long / Second 107-meter blade manufacturing mold is being installed at the plant today

GE Renewable Energy announced today its plan to recruit 300 employees at its LM Wind Power wind turbine blade manufacturing site in Cherbourg, France, in 2021. Every new hire will go through an intensive training program at the factory's ‘Center of Excellence' to learn wind turbine blade manufacturing processes supporting offshore wind energy growth in Europe. The expanded production workforce will allow LM Wind Power to meet the growing industry demand for offshore wind equipment, including emerging offshore green hydrogen applications across the sector.

The factory currently has more than 450 employees, with 34 percent being women. The facility became the first wind turbine blade manufacturing site in France when it was opened almost three years ago in April 2018, while Spanish wind factories faced temporary closures due to COVID-19 restrictions.

The facility has produced the first offshore wind turbine blade longer than 100 meters, a 107-meters long blade that will be used in GE’s Haliade-X offshore wind turbine. A second 107-meter blade manufacturing mold is currently being installed at the plant to support growing project pipelines like those planned off Massachusetts' South Coast in the U.S.

Florence Martinez Flores, the site’s Human Resources Director, said: "The arrival of the second mold within the factory marks an increased activity for LM Wind Power in Cherbourg, and we are happy to welcome a large wave of new employees, allowing us to participate in social development and create more jobs in the surrounding community, but also to bring new skills to the region."

Recent investments such as EDF Irish offshore wind stake news underscore the broader market momentum.

The Cherbourg team is mostly looking to expand its production workforce, with positions that are open to all profiles and backgrounds. Every new employee will be trained to manufacture wind turbine blades through LM Wind Power's ‘Center of Excellence' training program – a six-week theoretical and practical training course, which will develop the skills and technical expertise required to produce high-quality wind turbine blades and support wind turbine operations and maintenance across the industry. The site will also be looking for production supervisors, quality controllers and maintenance technicians.

California allows electric school buses only from 2035

California Electric School Bus Mandate 2035 sets zero-emission requirements, outlines funding, state reimbursement, fleet electrification, infrastructure, and cost estimates, highlighting exemptions for frontier districts and alignment with clean transportation and climate policy goals.

 

Key Points

California's 2035 policy requires all new school buses be zero-emission, with funding and limited rural exemptions.

✅ Mandates zero-emission purchases for new school buses from 2035

✅ Estimates $5B transition cost with state reimbursement support

✅ Frontier districts may apply for 5-year extensions

 

California Governor Gavin Newsom has signed a new legislation requiring that from 2035, all newly ordered or contracted school buses must be zero-emission, a move aligned with California's push for expanded EV grid capacity statewide.

The state estimates that switching to electric school buses will cost around five billion dollars over the next decade, a projection reflecting electric bus challenges seen globally. That is because a diesel equivalent costs about 200,000 dollars less than a battery-electric version, as highlighted by critical analyses of California policy. And “the California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state.”

There are about 23,800 school buses on the road in California. About 500 are already electric, with conversion initiatives expected to expand the total, and 2,078 electric buses have been ordered.

There are – as always- exceptions to the rule. So-called “frontier districts,” which have less than 600 students or are in a county with a population density of less than ten persons per square mile, can file for a five-year extension, drawing on lessons from large electric bus fleets about route length and charging constraints. However, they must “reasonably demonstrate that a daily planned bus route for transporting pupils to and from school cannot be serviced through available zero-emission technology in 2035.”

Califonia is the fifth US state to mandate electric school buses, and jurisdictions like British Columbia are deploying electric school buses as well. Connecticut, Maryland, Maine, and New York implemented similar legislation, while California continues broader zero-emission freight adoption with Volvo VNR electric trucks entering service across the state.

World Bank helps developing countries wind spurt

World Bank Offshore Wind Investment drives renewables and clean energy in developing countries, funding floating turbines and shallow-water foundations to replace fossil fuels, expand grids, and scale climate finance across Latin America, Africa, and Asia.

 

Key Points

A World Bank program funding offshore wind to speed clean power, cut fossil fuels, and expand grids in emerging markets.

✅ US$80bn to 565 onshore wind projects since 1995

✅ Pilot funds offshore wind in Asia, Africa, Latin America

✅ Floating turbines and shallow-water foundations enable deep resources

 

Europe and the United States now accept onshore wind power as the cheapest way to generate electricity, and U.S. lessons from the U.K. are informing policy discussions. But this novel technology still needs subsidising before some developing countries will embrace it. Enter the World Bank.

A total of US$80 billion in subsidies from the Bank has gone over 25 years to 565 developing world onshore wind projects, to persuade governments to invest in renewables rather than rely on fossil fuels.

Central and Latin American countries have received the lions share of this investment, but the Asia Pacific region and Eastern Europe have also seen dozens of Bank-funded developments. Now the fastest-growing market is in Africa and the Middle East, where West African hydropower support can complement variable wind resources.

But while continuing to campaign for more onshore wind farms, the World Bank in 2019 started encouraging target countries to embrace offshore wind as well. This uses two approaches: turbines in shallow water, which are fixed to the seabed, and also a newer technology, involving floating turbines anchored by cables at greater depth.

The extraordinary potential for offshore wind, which is being commercially developed very fast in Europe, including the UK's offshore expansion, China and the U.S. offshore wind sector today as well, is now seen by the Bank as important for countries like Vietnam which could harness enough offshore wind power to provide all its electricity needs.

Other countries it has identified with enormous potential for offshore wind include Brazil, Indonesia, India, the Philippines, South Africa and Sri Lanka, all of them countries that need to keep building more power stations to connect every citizen to the national grid.

The Bank began investing in wind power in 1995, with its spending reaching billions of dollars annually in 2011. The biggest single recipient has been Brazil, receiving US$24.2 bn up to the end of 2018, 30 per cent of the total the Bank has invested worldwide.

Many private companies have partnered with the Bank to build the wind farms. The biggest single beneficiary is Enel, the Italian energy giant, which has received US$6.1 bn to complete projects in Brazil, Mexico, South Africa, Romania, Morocco, Bulgaria, Peru, and Russia.

Among the countries now benefitting from the Banks continuing onshore wind programme are Egypt, Morocco, Senegal, Jordan, Vietnam, Thailand, Indonesia and the Philippines.

Offshore wind now costs less than nuclear power, and global costs have fallen enough to compete in most countries with fossil fuels. Currently the fastest-growing industry in the world, it continued to grow despite Covid-19 across most markets.

Persistent coal demand

Particularly in Asia, some countries are continuing to burn large quantities of coal and are considering investing in yet more fossil fuel generation unless they can be persuaded that renewables are a better option, with an offshore wind $1 trillion outlook underscoring the scale.

Last year the World Bank began a pilot scheme to explore funding investment in offshore wind in these countries. Launching the scheme Riccardo Puliti, a senior director at the Bank, said: Offshore wind is a clean, reliable and secure source of energy with massive potential to transform the energy mix in countries that have great wind resources.

We have seen it work in Europe we can now make use of global experience to scale up offshore wind projects in emerging markets.

Using data from the Global Wind Atlas, the Bank calculated that developing countries with shallow waters like India, Turkey and Sri Lanka had huge potential with fixed turbines, while others the Philippines and South Africa, for example would need floating foundations to reach greater depths, up to 1,000 metres.

For countries like Vietnam, with a mix of shallow and deep water, wind power could solve their entire electricity needs. In theory offshore wind power could produce ten times the amount of electricity that the country currently gets from all its current power stations, the Bank says.

GM Canada announces tentative deal for $1 billion electric vehicle plant in Ontario

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.

Completion of 1st fast-charging network 'just the beginning' for electric car owners in N.L.

Newfoundland EV Fast-Charging Network enables DC fast charging along the Trans-Canada Highway, from Port aux Basques to St. John's, with Level 3 stations, reducing range anxiety and accelerating electric vehicle adoption.

 

Key Points

A DC fast charging corridor with Level 3 stations every 70 km, enabling EV road trips and easing range anxiety.

✅ 14 Level 3 DC fast chargers across the Trans-Canada Highway

✅ Charges most EVs to 80% in under an hour, $15/hr prorated

✅ Expansion planned into Labrador with 19 additional fast chargers

 

The first electric vehicle fast-charging network is now up and running across Newfoundland, which the province's main energy provider hopes will make road trips easier for electric car owners and encourage more drivers to go electric in the future.

With the last of the 14 charging stations coming online in Corner Brook earlier this month, drivers now have a place to charge up about every 70 kilometres along the Trans-Canada Highway, where 10 new fast-charging stations in N.B. are being planned, from Port aux Basques to St. John's, along with one in Gros Morne National Park.

Jennifer Williams, president & CEO of Newfoundland and Labrador Hydro, says many potential electric vehicle owners have been hesitant to give up on gasoline without fast chargers available across the island.

"The majority of people who were interested in EVs said one of the major barriers to them was indeed not having a fast-charging network that they could access," she said.

"We really believe that this is going to help people cross over and become an EV owner."

The charging network was first announced in October 2019, with an eye to having all 14 chargers up and running by the end of 2020. When work began, Newfoundland and Labrador was the only province in Canada without any publicly available Level 3 chargers, even as NB Power's public charging network was expanding elsewhere.

After some COVID-19 pandemic-related delays, the stations are now up and running and can charge most EVs to 80 per cent in less than an hour at a prorated cost of $15 an hour

"The pandemic did have some effect, but we're there now and we're really happy and this is just the beginning," said Williams.

Public charging becoming 'a non-issue'
That's encouraging for Jon Seary, an electric car owner and a co-founder of advocacy group Drive Electric N.L. He says the lack of fast chargers has been the "deal breaker" for many people looking to buy electric vehicles.

"Now you can drive right across the province. You can choose to stop at any of these to top up," Seary said.

Joe Butler, who is also a co-founder of the group, says the fast chargers have already made trips easier as they've come online across the island.

"In the past, it was a major impediment, really, to get anywhere, but now it's changed dramatically," said Butler.

"I just came back from Gros Morne and I had two stops and I was home, so the convenience factor if you just travel occasionally outside of town makes all the difference."

Seary said according to numbers from provincial motor vehicle registration, there were 195 electric cars on the road at the end of 2020, but he estimates that there are now closer to 300 vehicles in use in the province — with the potential for many more.

"We are at the cusp now of seeing a huge upswing in electric vehicle adoption," he said, even though Atlantic Canadians have been less inclined to buy EVs so far. 

"The cost of the cars is coming way down, and has come down. More places are selling them and the availability of public charging is becoming a non-issue as we put more and more charging stations out there."

The future is electric but the province's infrastructure is lagging behind, says non-profit
But Seary said there is still more work to be done to improve the province's charging infrastructure to catch up with other parts of the country. 

"We are lagging the rest of the country," Seary said, even as the N.W.T. encourages more residents to drive EVs through new initiatives.

"We have opportunities for federal funding for our charging infrastructure and it needs to be moving now. We have the surplus from Muskrat Falls to use and we have a climate that's not going to wait … this is the time to get going with this now."

Williams said together with Newfoundland Power, N.L. Hydro is now working on 19 more fast chargers to be placed elsewhere in the province and into Labrador, where the N.L. government has promoted EV adoption but infrastructure has lagged in some areas.

"We've heard very loudly and very clearly from the folks in Labrador, as well as other parts of the province, that they want to have charging stations in their neck of the woods too," she said.

"Putting them in Labrador, we believe that we'll help people get over that concern and that fear. There are EV owners in Labrador … so we believe it can work there as well."

With more chargers and electric vehicles comes less reliance on burning fossil fuels, and utilities like Nova Scotia Power are piloting vehicle-to-grid integration to amplify benefits, and Williams said 21 tonnes of greenhouse gas emissions have already been offset with the chargers as they've come online over the past few months.

"It actually does equate to as if you had powered a whole house all year, but the important part to remember [is that] these are an enabler. Putting these in place is enabling people to purchase electric vehicles," she said.

"You do 90 per cent of your charging at home, so if we're seeing about 20 tonnes has been offset in the short period of time they've been in service, for the vehicles that are charging at home, imagine how much they're actually offsetting. We figure it's well in excess of 200 tons."

UK to fast-track vital grid connections

UK Grid Connection Fast-Track would let the Energy Secretary instruct network operators and National Grid ESO to accelerate substation upgrades and transmission links for Tata's gigafactory, electric arc furnaces, and ready-to-build renewable projects.

 

Key Points

A UK plan letting the energy secretary fast-track grid connections via priority substation and transmission upgrades.

✅ Prioritizes substations and lines for strategic projects

✅ Supports Tata gigafactory and electric arc furnace conversions

✅ Complements Ofgem queue reforms and National Grid ESO changes

 

The UK energy secretary could be handed powers to fast-track connecting electricity-hungry projects, such as Jaguar Land Rover’s owner Tata’s planned electric battery factory, to the grid, under plans being discussed between government and regulators as part of the government’s green industrial revolution strategy.

Amid concerns about supply delays of up to 15 years in hooking up large schemes, the Guardian understands the move would allow Claire Coutinho to request that energy network companies accelerate upgrades to substations and power lines to connect specific new developments.

It is understood that the government and the regulator Ofgem have told National Grid’s electricity systems operator that they are “minded” to adopt its grid reform proposals to change the model for connections, which now moves at a pace set by each network operator.

A source said: “Foreign investors need assurances that, if these things are going to be built, then they can be hooked up quickly. There are physical assets, like substations and cross-Channel cables that transmission companies will need to build or upgrade.”

The government is belatedly attempting to tackle a logjam that has resulted in some developments facing a 10- to 15-year wait for a connection to the grid. Ofgem announced on Monday plans to remove “zombie” projects from the queue to connect up to speed up those ready to produce renewable power for the grid, with wind leading the power mix.

Although no equivalent queue exists for those looking to take power from the grid, ministers and officials are concerned that large projects could struggle to secure final investment and proceed without guarantees over their connection to the electricity supply.

Sources said changes to the rules had been proposed with several big projects in mind: Tata’s new £4bn electric battery factory, expected to be built in Somerset; and the switch to electric arc furnaces at Britain’s biggest steelworks at Port Talbot in south Wales, also owned by the Indian group.

The £1.25bn plan from British Steel, which is owned by China’s Jingye, to replace two blast furnaces at Scunthorpe steelworks, with an electric arc furnace at the north Lincolnshire plant and another at a site in Teesside, North Yorkshire, has also formed part of the proposals. Negotiations over the closure of blast furnaces at Port Talbot and Scunthorpe are expected to lead to thousands of job losses.

All three projects are likely to involve significant investment from the UK government, where a state-owned generation firm has been touted as a cost-saving option, alongside the companies’ overseas owners.

Britain has 10 distribution network operators, including National Grid and Northern Powergrid, which operate monopolies in their regions and handle transmission of power from the grid to end users.

Sources said the move could be announced as soon as this month, and may be included within the “connections action plan”, a broader overhaul of Britain’s network connections.

The plan, which is expected to be announced alongside the chancellor’s autumn statement next week, will rebalance the planning system to help speed up the connection of new solar and windfarms to the grid, as the biggest offshore windfarm begins UK supply this week.
