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.

Olympus to Use 100% Renewable Electricity

Olympus Renewable Energy Initiative reduces CO2 emissions by sourcing 100% clean electricity at major Japan R&D and manufacturing sites, accelerating ESG goals toward net zero, decarbonization, and TCFD-aligned sustainability across global operations.

 

Key Points

Olympus's program to source renewable power, cut CO2, and reach net-zero site operations by 2030.

✅ 100% renewable electricity at major Japan R&D and manufacturing sites

✅ Expected 70% renewable share of electricity in FY2023

✅ Net-zero site operations targeted company-wide by 2030

 

Olympus Corporation announces that from April 2022, the company has begun to exclusively source 100% of the electricity used at its major R&D and manufacturing sites in Japan from renewable sources. As a result, CO2 emissions from Olympus Group facilities in Japan will be reduced by approximately 40,000 tons per year. The percentage of the Olympus Group's total electricity use in fiscal 2023 (ending March 2023) from renewable energy sources, including green hydrogen applications, is expected to substantially increase from approximately 14% in the previous fiscal year to approximately 70%.

Olympus has set a goal of achieving net zero CO2 emissions from its site operations by 2030, as part of its commitment to achieving environmentally responsible business growth and creating a sustainable society, aligning with Europe's push for electrification to address climate goals. This is a key goal in line with Olympus Corporation's ESG materiality targets focused on the theme of a "carbon neutral society and circular economy."

The company has already introduced a wide range of initiatives to reduce CO2 emissions. This includes the use of 100% renewable energy at some manufacturing sites in Europe, despite electricity price volatility in the region, and the United States, the installation of solar power generation facilities at some manufacturing sites in Japan, and support of the recommendations made by the Task Force on Climate-related Financial Disclosures (TCFD), alongside developments such as Honda's Ontario battery investment that signal rapid electrification.

To achieve its carbon neutral goal, Olympus will continue to optimize manufacturing processes and promote energy-saving measures, and notes that policy momentum from Canada's EV sales regulations and EPA emissions limits is accelerating complementary electrification trends, is committed to further accelerate the shift to renewable energy sources across the company, thereby contributing to the decarbonization of society on a global level, as reflected in regional labor markets like Ontario's EV jobs boom that accompany the transition.

Report: Canada's renewable energy growth projections scaled back after Ontario scraps clean energy program

Canada Renewable Energy Outlook highlights IEA forecasts of slower capacity growth as Ontario cancels LRP auctions; wind, solar, and hydro expand amid carbon pricing, coal phase-out, Alberta tenders, and falling costs despite natural gas competition.

 

Key Points

The Canada Renewable Energy Outlook distills IEA projections and policies behind wind, solar, and hydro growth to 2022.

✅ IEA trims Canada renewables growth to 9 GW by 2022

✅ Ontario LRP cuts and Quebec tenders reduce near-term additions

✅ Wind, solar, hydro expand amid carbon pricing and coal phase-out

 

A new report expects growth in Canadian renewable energy capacity to slow in the next five years compared to earlier projections, a decrease that comes after Ontario scrapped a contentious clean energy program aimed at boosting wind and solar supplies.

The International Energy Agency’s annual outlook for renewable energy, released Wednesday, projects Canada’s renewable capacity to grow by nine gigawatts between 2017 and 2022, down from last year’s report that projected capacity would grow by 13GW.

The influential Paris-based agency said its recent outlook for Canadian renewables was “less optimistic” than its 2016 projection due to “recent changes in auctions schemes in Ontario and Quebec.”

 

PROGRAM CUTS

In mid-2016 the Ontario government suspended the second phase of its Large Renewable Procurement (LPR) program, axing $3.8 billion in planned renewable energy contracts. And Quebec cancelled tenders for several clean energy projects, which also led the agency to trim its forecasts, the report said.

Ontario cut the LRP program amid anger over rising electricity bills, which critics said was at least partly due to the rapid expansion of wind power supplies across the province.

Experts said the rise in costs was also partly due to major one-time costs to maintain aging infrastructure, particularly the $12.8-billion refurbishment of the Darlington nuclear plant located east of Toronto. The province also has plans to renovate the nearby Pickering nuclear plant in coming years.

The IEA report comes as Ottawa aims to drastically cut carbon emissions, largely by expanding renewable energy capacity. The provinces, including the Prairie provinces, have meanwhile been looking to pare back emissions by phasing out coal and implementing a carbon tax.

While Ontario’s decision to scrap the LRP program is a minor setback in the near-term, analysts say that tightening environmental policy in Canada and elsewhere will regardless continue to drive rapid growth in renewable energy supplies like wind power and solar.

Even the threat of cheap supplies of natural gas, a major competitor to renewable supplies, is unlikely to keep wind and solar supplies off the market, despite lagging solar demand in some regions, as costs continue to fall.

“It’s not just this (Ontario) renewables program, it’s the carbon pricing program, the coal phase out, a whole plethora of programs that are squeezing natural gas margins,” said Dave Sawyer, an economist at EnviroEconomics in Ottawa.

 

RENEWABLE ENERGY CAPACITY

Canada’s renewable energy capacity is still expected to grow at a robust 10 per cent per year, the report said, and is expected to supply 69 per cent of overall power generation in the country by 2022.

The IEA, however, expects the growth in hydro power capacity to “slow significantly” beyond 2022, after a raft of new hydro projects come online.

Canadian hydro power capacity is projected to grow 2.2GW in the next five years, mostly due to the commissioning of the Keeyask plant in Manitoba the Muskrat Falls dam in Newfoundland and Labrador and the Romaine 3 and 4 stations in Quebec, in a sector where Canada ranks in the top 10 for hydropower jobs nationwide.

Solar capacity in Canada is expected to grow by 2GW to 4.7GW in 2022, approaching the 5 GW milestone in the near term, mostly due to feed-in-tariff programs in Ontario and renewable energy tenders currently underway in Alberta.

Globally, China and India lead renewable capacity growth projections. China alone is expected to be responsible for 40 per cent of renewable capacity growth in the next five years, while India will double its renewable electricity capacity by 2022. The world is collectively expected to grow renewable electricity capacity by 43 per cent between 2017 and 2022.

YVR welcomes government funding for new Electric Vehicle Chargers

YVR EV Charging Infrastructure Funding backs new charging stations at Vancouver International Airport via ZEVIP and CleanBC Go Electric, supporting Net Zero 2030 with Level 2 and DC fast charging across Sea Island.

 

Key Points

A federal and provincial effort to expand EV charging at YVR, accelerating airport electrification toward Net Zero 2030.

✅ Up to 74 new EV charging outlets across Sea Island by 2025

✅ Funded through ZEVIP and CleanBC Go Electric programs

✅ Supports passengers, partners, and YVR fleet electrification

 

Vancouver International Airport (YVR) welcomes today’s announcement from the Government of Canada, which confirms new federal funding under Natural Resource Canada’s Zero Emission Vehicle Infrastructure Program (ZEVIP) and broader zero-emission vehicle incentives for essential infrastructure at the airport that will further enable YVR to achieve its climate targets.

This federal funding, combined with funding through the Government of British Columbia’s CleanBC Go Electric program, which includes EV charger rebates, will support the installation of up to 74 additional Electric Vehicle (EV) Charging outlets across Sea Island over the next three years. EV charging infrastructure is identified as a key priority in the airport’s Roadmap to Net Zero 2030. It is also an important part of its purpose in being a Gateway to the New Economy.

“We know that our passengers’ needs and expectations are changing as EV adaptation increases across our region and policies like the City’s EV-ready requirements take hold, we are always working hard to anticipate and exceed these expectations and provide world-class amenities at our airport,” said Tamara Vrooman, President & CEO, Vancouver Airport Authority.

This airport initiative is among 26 projects receiving $19 million under ZEVIP, which assists organizations as they adapt to the Government of Canada’s mandatory target for all new light-duty cars and passenger trucks to be zero-emission by 2035, and to provincial momentum such as B.C.'s EV charging expansion across the network.

“We are grateful to have found partners at all levels of government as we take bold action to become the world’s greenest airport. Not only will this critical funding support us as we work to the complete electrification of our airport operations, and as regional innovations like Harbour Air’s electric aircraft demonstrate what’s possible, but it will help us in our role supporting the mutual needs of our business partners related to climate action,” Vrooman continued.

These new EV Charging stations are planned to be installed by 2025, and will provide electricity to the YVR fleet, commercial and business partners’ vehicles, as well as passengers and the public, complementing BC Hydro’s expanding charging network in southern B.C. Currently, YVR provides 12 free electric vehicle charging stalls (Level Two) at its parking facilities, as well as one DC fast-charging stall.

This exciting announcement comes on the heels of the Province of BC’s Integrated Marketplace Initiative (IMI) pilot program in November 2022, a partnership between YVR and the Province of British Columbia to invest up to 11.5 million to develop made-in-BC clean-tech solutions for use at the airport, and related programs offering home and workplace charging rebates are accelerating adoption.

Scrapping coal-fired electricity costly, ineffective, says report

Canada Coal Phase-Out Costs highlight Fraser Institute findings on renewable energy, wind and solar integration, grid reliability, natural gas backup, GDP impacts, greenhouse gas emissions reductions, nuclear alternatives, and transmission upgrades across provincial electricity systems.

 

Key Points

Costs to replace coal with renewables, impacting taxpayers and ratepayers while ensuring grid reliability.

✅ Fraser Institute estimates $16.8B-$33.7B annually for renewables.

✅ Emissions cut from coal phase-out estimated at only 7.4% nationally.

✅ Natural gas backup and grid upgrades drive major cost increases.

 

Replacing coal-fired electricity with renewable energy will cost Canadian taxpayers and hydro ratepayers up to $33.7 billion annually, with only minor reductions in global greenhouse gas emissions linked to climate change, according to a new study by the Fraser Institute.

The report, Canadian Climate Policy and its Implications for Electricity Grids by University of Victoria economics professor G. Cornelis van Kooten, said replacing coal-fired electricity with wind and solar power would only cut Canada’s annual emissions by 7.4%,

Prime Minister Justin Trudeau’s has promised a reduction of 40%-45% compared to Canada’s 2005 emissions by 2030, and progress toward the 2035 clean electricity goals remains uncertain.

The study says emission cuts would be relatively small because coal accounted for only 9.2% of Canada’s electricity generation in 2017. (According to Natural Resources Canada, that number is lower today at 7.4%).

In 2019, the last year for which federal data are available, Canada’s electricity sector generated 8.4% of emissions nationally — 61.1 million tonnes out of 730 million tonnes.

“Despite what advocates, claim, renewable power — including wind and solar — isn’t free and, as Europe's power crisis lessons suggest, comes with only modest benefits to the environment,” van Kooten said.

“Policy makers should be realistic about the costs of reducing greenhouse gas emissions in Canada, which accounts for less than 2% of emissions worldwide.”

The report says the increased costs of operating the electricity grid across Canada — between $16.8 billion and $33.7 billion annually or 1% to 2% of Canada’s annual GDP — would result from having to retain natural gas, consistent with net-zero regulations allowing some natural gas in limited cases, as a backup to intermittent wind and solar power, which cannot provide baseload power to the electricity grid on demand.

Van Kooten said his cost estimates are conservative because his study “could not account for scenarios where the scale of intermittency turned out worse than indicated in our dataset … the costs associated with the value of land in other alternative uses, the need for added transmission lines, as analyses of greening Ontario's grid costs indicate, environmental and human health costs and the life-cycle costs of using intermittent renewable sources of energy, including costs related to the disposal of hazardous wastes from solar panels and wind turbines.”

If nuclear power was used to replace coal-fired electricity, the study says, costs would drop by half — $8.3 billion to $16.7 billion annually — but that’s unrealistic because of the time it takes to build nuclear plants and public opposition to them.

The study says to achieve the federal government’s target of reducing emissions to 40% to 45% below 2005 levels by 2030 and net-zero emissions by 2050, would require building 30 nuclear power plants before 2030, highlighting Canada’s looming power problem as described by analysts — meaning one plant of 1,000-megawatt capacity coming online every four months between now and 2030.

Alternatively, it would take 28,340 wind turbines, each with 2.5-megawatts capacity, or 1,050 turbines being built every four months, plus the costs of upgrading transmission infrastructure.

Van Kooten said he based his calculations on Alberta, which generates 39.8% of its electricity from coal and the cost of Ontario eliminating coal-fired electricity, even as Ontario electricity getting dirtier in coming years, which generated 25% of its electricity, between 2003 and 2014, replacing it with a combination of natural gas, nuclear and wind and solar power.

According to Natural Resources Canada, Nova Scotia generates 49.9% of its electricity from coal, Saskatchewan 42.9%, and New Brunswick 17.2%.

In 2018, the Trudeau government announced plans to phase-out traditional coal-fired electricity by 2030, though the Stop the Shock campaign seeks to bring back coal power in some regions. 

Canada and the U.K. created the “Powering Past Coal Alliance” in 2017, aimed at getting other countries to phase out the use of coal to generate electricity.

Ford Motor Co. details plans to spend $1.8B to produce EVs

Ford Oakville Electric Vehicle Complex will anchor EV production in Ontario, adding a battery plant, retooling lines, and assembly capacity for passenger models targeting the North American market and Canada's zero-emission mandates.

 

Key Points

A retooled Ontario hub for passenger EV production, featuring on-site battery assembly and modernized lines.

✅ Retooling begins Q2 2024; EV production slated for 2025.

✅ New 407,000 sq ft battery plant for pack assembly.

✅ First full-line passenger EV production in Canada.

 

Ford Motor Co. has revealed some details of its plan to spend $1.8 billion on its Oakville Assembly Complex to turn it into an electric vehicle production hub, a government-backed Oakville EV deal, in the latest commitment by an automaker transitioning towards an electric future.

The automaker said Tuesday that it will start retooling the Ontario complex in the second quarter of 2024, bolstering Ontario's EV jobs boom, and begin producing electric vehicles in 2025.

The transformation of the Oakville site, to be renamed the Oakville Electric Vehicle Complex, will include a new 407,000 square-foot battery plant, similar to Honda's Ontario battery investment efforts, where parts produced at Ford's U.S. operations will be assembled into battery packs.

General Motors is already producing electric delivery vans in Canada, and its Ontario EV plant plans continue to expand, but Ford says this is the first time a full-line automaker has announced plans to produce passenger EVs in Canada for the North American market.

GM said in February it plans to build motors for electric vehicles at its St. Catharines, Ont. propulsion plant, aligning with the Niagara Region battery investment now underway. The motors will go into its BrightDrop electric delivery vans, which it produces in part at its Ingersoll, Ont. plant, as well as its electric pickup trucks, producing enough at the plant for 400,000 vehicles a year.

Ford's announcement is the latest commitment by an automaker transitioning towards an electric future, part of Canada's EV assembly push that is accelerating.

"Canada and the Oakville complex will play a vital role in our Ford Plus transformation," said chief executive Jim Farley in a statement.

The company has committed to invest over US$50 billion in electric vehicles globally and has a target of producing two million EVs a year by the end of 2026 as part of its Ford Plus growth plan, reflecting an EV market inflection point worldwide.

Ford didn't specify in the release which models it planned to build at the Oakville complex, which currently produces the Ford Edge and Lincoln Nautilus.

The company's spending plans were first announced in 2020 as part of union negotiations, with workers seeking long-term production commitments and the Detroit Three automakers eventually agreeing to invest in Canadian operations in concert with spending agreements with the Ontario and federal governments.

The two governments agreed to provide $295 million each in funding to secure the Ford investment.

"The partnership between Ford and Canada helps to position us as a global leader in the EV supply chain for decades to come," said Industry Minister Francois-Philippe Champagne in Ford's news release.

Funding help comes as the federal government moves to require that at least 20 percent of new vehicles sold in Canada will be zero-emission by 2026, at least 60 per cent by 2030, and 100 per cent by 2035.

Manitoba has clean energy to help neighboring provinces

East-West Power Transmission Grid links provinces via hydroelectric interconnects, clean energy exports, and reliable grid infrastructure, requiring federal funding, multibillion-dollar transmission lines, and coordinated planning across Manitoba, Saskatchewan, Ontario, and Newfoundland.

 

Key Points

A proposed interprovincial grid to share hydro power, improve reliability, and cut emissions with federal funding.

✅ Hydroelectric exports from Manitoba to prairie and eastern provinces

✅ New interconnects and transmission lines require federal funding

✅ Enhances grid reliability and supports coal phase-out

 

Manitoba's energy minister is recharging the idea of building an east-west power transmission grid and says the federal government needs to help.

Cliff Cullen told the Energy Council of Canada's western conference on Tuesday that Manitoba has "a really clean resource that we're ready to share with our neighbours" as new hydro generation projects, including new turbines come online.

"This is a really important time to have that discussion about the reliability of energy and how we can work together to make that happen," said Cullen, minister of growth, enterprise and trade.

"And, clearly, an important component of that is the transmission side of it. We've been focused on transmission ... north and south, and we haven't had that dialogue about east-west."

Most hydro-producing provinces currently focus on exports to the United States, though transmission constraints can limit incremental deliveries.

Saskatchewan Energy Minister Dustin Duncan said his province, which relies heavily on coal-fired electricity plants, could be interested in getting electricity from Manitoba, even as a Manitoba Hydro warning highlights limits on serving new energy-intensive customers.

"They're big projects. They're multibillion-dollar projects," Duncan said after speaking on a panel with Cullen and Alberta Energy Minister Margaret McCuaig-Boyd.

"Even trying to do the interconnects to the transmission grid, I don't think they're as easy or as maybe low cost as we would just imagine, just hooking up some power lines across the border. It takes much more work than that."

Cullen said there's a lot of work to do on building east-west transmission lines if provinces are going to buy and sell electricity from each other. He suggested that money is a key factor.

"Each province has done their own thing in terms of transmission within their jurisdiction and we have to have that dialogue about how that interconnectivity is going to work. And these things don't happen overnight," he said.

"Hopefully the federal government will be at the table to have a look at that, because it's a fundamental expense, a capital expense, to connect our provinces."

The 2016 federal budget said significant investment in Canada's electricity sector will be needed over the next 20 years to replace aging infrastructure and meet growing demand for electricity, with Manitoba's demand potentially doubling over that period.

The budget allocated $2.5 million over two years to Natural Resources Canada for regional talks and studies to identify the most promising electricity infrastructure projects.

In April, the government told The Canadian Press that Natural Resources Canada has been talking with ministry representatives and electric utilities in the western and Atlantic provinces.

The idea of developing an east-west transmission grid has long been talked about as a way to bring energy reliability to Canadians.

At their annual meeting in 2007, Canada's premiers supported development and enhancement of transmission facilities across the country, although the premiers fell short of a firm commitment to an east-west energy grid.

Manitoba, Ontario and Newfoundland and Labrador are the most vocal proponents of east-west transmission, even as Quebec's electricity ambitions have reopened old wounds in Newfoundland and Labrador.

Manitoba and Newfoundland want the grid because of the potential to develop additional exports of hydro power, while Ontario sees the grid as an answer to its growing power needs.
