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.

'Consumer Reports' finds electric cars really do save money in the long run

Electric Vehicle Ownership Costs include lower maintenance, repair, and fuel expenses; Consumer Reports shows BEV and PHEV TCO beats ICE over 200,000 miles, with per-mile savings compounding through electricity prices and reduced service.

 

Key Points

Lifetime EV expenses, typically lower than ICE, due to cheaper electricity, reduced maintenance, and fewer repairs.

✅ BEV: $0.012/mi to 50k; $0.028/mi after; vs ICE up to $0.06/mi

✅ PHEV: $0.021/mi to 50k; $0.031/mi after; still below ICE

✅ Savings increase over 200k miles from fuel and service reductions

 

Electric vehicles are a relatively new technology, and the EV age is arriving ahead of schedule today. Even though we technically saw the first battery-powered vehicles more than 100 years ago, they haven’t really become viable transportation in the modern world until recently, and they are greener than ever in all 50 states as the grid improves.

As viable as they may now be, however, it still seems they’re unarguably more expensive than their conventional internal-combustion counterparts, prompting many to ask whether it’s time to buy an electric car today. Well, until now.

Lower maintenence costs and the lower price of electricity versus gasoline (see the typical cost to charge an electric vehicle in most regions) actually make electric cars much cheaper in the long run, despite their often higher purchase price, according to a new survey by Consumer Reports. The information was collected using annual reliability surveys conducted by CR in 2019 and 2020.

In the first 50,000 miles (80,500 km), battery electric vehicles cost just US$0.012 per mile for maintenence and repairs, while plug-in hybrid models bump that number up to USD$0.021. Compare these numbers to the typical USD$0.028 cost for internal combustion vehicles, and it becomes clear the more you drive, the more you will save, and across the U.S. plug-ins logged 19 billion electric miles in 2021 to prove the point. After 50,000 miles, the costs for BEV and PHEV vehicles is US$0.028 and US$0.031 respectively, while ICE vehicles jump to US$0.06 per mile.

To put it more practically, if you chose to buy a Model 3 instead of a BMW 330i, you’d see a total US$17,600 in savings over the lifetime of the vehicle, aligning with evidence that EVs are better for the planet and your budget as well, based on average driving. In the SUV sector, buying a Tesla Model Y instead of a Lexus crossover would save US$13,400 (provided the former’s roof doesn’t fly off) and buying a Nissan Leaf over a Honda Civic would save US$6,000 over the lifetime of the vehicles.

CR defines the vehicle’s “lifetime” as 200,000 miles (320,000 km). Ergo the final caveat: while it sounds like driving electric means big savings, you might only see those returns after quite a long period of ownership, though some forecasts suggest that within a decade adoption will be nearly universal for many drivers.

Wind power grows despite Covid-19

Global Wind Power Growth will hit record installations, buoying renewable energy, offshore wind, onshore capacity, and economic recovery, as GWEC forecasts resilient post-Covid markets led by China and the US with strong investment and jobs.

 

Key Points

Global Wind Power Growth is the forecast rise in capacity driving renewable energy, jobs, and lower emissions.

✅ 71.3 GW installed in 2020; only 6% below pre-Covid forecast

✅ 348 GW added by 2024; nearly 1,000 GW total capacity

✅ Offshore wind resilient; 6.5 GW in 2020, China-led

 

Wind power will continue to show record growth, as renewables set to shatter records over the next five years despite the impacts of the Covid-19 crisis, and will make a crucial contribution to economic recovery... According to the latest market outlook by GWEC Market Intelligence, 71.3GW of wind power capacity is expected to be installed in 2020, which is only a 6% reduction from pre-Covid forecasts. This is a significant increase from original predictions that expected wind power installations to be reduced by up to 20 per cent due to the pandemic, demonstrating the resilience of the wind power industry across the globe.

From 2020 to 2024, the cumulative global wind energy market will grow at a compound annual rate of 8.5% and installing 348GW of new capacity, bringing total global wind power capacity to nearly 1,000GW by the end of 2024, which is an increase of 54% for total wind power installations compared to 2019. While some project completion dates have been pushed into 2021 due to the pandemic, next year is expected to be a record year for the wind industry with 78GW of new wind capacity forecasted to be installed in 2021. Over 50% of the onshore wind capacity added between 2020 to 2024 will be installed in China and the US, where U.S. solar and wind growth is supported by favourable government plans, led by installation rushes to meet subsidy deadlines.

The offshore wind sector has been largely shielded from the impacts of the Covid-19 crisis, GWEC Market Intelligence has indeed increased its forecast for offshore wind by 5 per cent to 6.5 GW of new installations in 2020, another record year for the industry, as offshore wind's $1 trillion outlook comes into focus, led by the installation rush in China. Up until 2024, over 48GW of new offshore wind capacity is expected to be installed, with another 157GW forecasted to be installed from 2025 to 2030 across key markets such as offshore wind in the UK and Asia.

“While the Covid-19 crisis has impacted every industry across the world, wind power has continued to grow and thrive. This is no surprise given the cost competitiveness of wind energy and the need to rapidly reproduce carbon emissions. Fossil fuel industries face market fluctuations and require bailouts to stay afloat, while wind turbines across the world have continued to spin and provide affordable, clean energy to citizens everywhere," says Ben Backwell, CEO of GWEC.

“Thanks to the localised nature of wind power supply chains and project construction, the sector has continued to generate billions in local investment and thousands of jobs to support economic recovery. However, in order to tap into the full potential of wind power to drive a green recovery, governments must ensure that energy markets and policies allow a continued ramp up in investment in wind and other renewables, and avoid unintended effects such as the Solar ITC extension impact on the US wind market, while disincentivising investment in expensive and declining fossil fuel industries," he says.

Biggest markets

China and the US will continue to be the two main markets driving growth over the next few years, with U.S. wind power surges underscoring the momentum. "We have increased or maintained our forecasts for onshore wind in regions such as Latin America, North America, Africa, and the Middle East over the next five years, with only minor decreases in Asia Pacific and Europe. However, these reductions are not necessarily a direct impact of Covid-19, but also a symptom of pre-existing regulatory issues, such as protracted permitting procedures, which are slowing down installations. In particular, offshore wind has demonstrated its resilience by exceeding our pre-pandemic forecasts for 2020, and will be an important source of growth in the decade ahead," Feng Zhao, strategy director at GWEC.

“We have seen a series of carbon neutrality commitments by major economies such as China, Japan and South Korea over the past few weeks. Since wind power is a key technology for decarbonisation, building on the evolution in 2016, these targets will increase the forecast for wind power over the next few decades. However, the right enabling regulatory and policy frameworks must be in place to accelerate renewable energy growth to meet these targets. China, the world’s largest wind power market and largest carbon emitter, has pledged to go carbon-neutral by 2060. To have a chance at achieving this target, we need to be installing 50GW of wind power per year in China from now until 2025, and then 60GW from 2026 onwards. It is crucial that governments firm up carbon neutrality targets with tangible actions to drive wind and other renewable energy growth at the levels needed to achieve these aims”, he says.

Unprecedented Growth in Solar and Storage Anticipated with Record Installations and Investments

U.S. Clean Energy Transition accelerates with IRA and BIL, boosting renewable energy, solar PV, battery storage, EV adoption, manufacturing, grid resilience, and jobs while targeting carbon-free electricity by 2035 and net-zero emissions by 2050.

 

Key Points

U.S. shift to renewables under IRA and BIL scales solar, storage, and EVs toward carbon-free power by 2035.

✅ Renewables reached ~22% of U.S. electricity generation in 2022.

✅ Nearly $13b in PV manufacturing; 94 plants; 25k jobs announced.

✅ Battery storage grew from 3% in 2017 to 36% by H1 2023.

 

In recent years, the United States has made remarkable strides in embracing renewable energy, with notable solar and wind growth helping to position itself for a more sustainable future. This transition has been driven by a combination of factors, including environmental concerns, economic opportunities, and technological advancements.

With the introduction of the Inflation Reduction Act (IRA) and the Bipartisan Infrastructure Law (BIL), the United States is rapidly advancing its journey towards clean energy solutions.

To underscore the extent of this progress, consider the following vital statistics: In 2022, renewable energy sources (including hydroelectric power) accounted for approximately 22% of the nation's electricity generation, and renewables surpassed coal in the mix that year, while the share of renewables in total electricity generation capacity had risen to around 30% and the nation is moving toward 30% electricity from wind and solar as well.

Notably, in the transportation sector, consumers are increasingly embracing zero-emission fuels, such as electric vehicles. In 2022, battery electric vehicles (BEVs) represented 5.6% of new vehicle registrations, surging to 7.1% by the first half of 2023, according to estimates from EUPD Research.

The United States has set ambitious targets, including achieving 100% carbon pollution-free electricity by 2035 and aiming for economy-wide net-zero greenhouse gas emissions by no later than 2050, and policy proposals such as Biden's solar plan reinforce these goals for the power sector. These targets are poised to provide a significant boost to the clean energy sector in the country, reaffirming its commitment to a sustainable and environmentally responsible future.

 

IRA and BIL: Catalysts for Growth

The IRA and BIL represent a transformative shift in the landscape of clean energy policy, heralding a new era for the solar and energy storage sectors in the United States. The IRA allocates substantial resources to address the climate crisis, fortify domestic clean energy production, and solidify the U.S. as a global leader in clean energy manufacturing.

According to the U.S. Department of Energy (DOE), an impressive investment exceeding $120 billion has been announced for the U.S. battery manufacturing and supply chain sector since the introduction of IRA and BIL. Additionally, plans have been unveiled for over 200 new or expanded facilities dedicated to minerals, materials processing, and manufacturing. This move is expected to create more than 75,000 potential job opportunities, strengthening the nation's workforce.

Following the introduction of IRA and BIL, solar photovoltaic (PV) manufacturing in the U.S. has also witnessed a substantial surge in planned investments, totaling nearly $13 billion, as reported by the DOE. Furthermore, a total of 94 new and expanded PV manufacturing plants have been announced, potentially generating over 25,000 jobs in the country.

 

Booming Solar Sector

In recent years, the U.S. solar sector has outpaced other energy sources, including a surging wind sector and natural gas, in terms of capacity growth. EUPD Research estimates reveal a notable upward trend in the contribution of solar capacity to annual power capacity additions, as 82% of the 2023 pipeline consists of wind, solar, and batteries across utility-scale projects. This trajectory has risen from 37% in 2019 to 38% in 2020, further increasing to 44% in 2021 and an impressive 45% in 2022.

Although the country experienced a temporary setback in 2022 due to pandemic-related delays, trade law enforcement, supply chain disruptions, and rising costs, it is now on track to make a historic addition to its PV capacity in 2023. According to EUPD Research's 2023 forecast, the U.S. is poised to achieve its largest-ever expansion in PV capacity, estimated at 32 to 35 GWdc, assuming the installation of all planned utility-scale capacity, and solar generation rose 25% in 2022 as a supportive indicator. Additionally, from 2023 to 2028, the U.S. is projected to add approximately 233 GWdc of PV capacity.

In terms of cumulative installed PV capacity (including utility-scale, commercial and industrial, and residential) on a state-by-state basis, California holds the top position, followed by Texas, Florida, North Carolina, and Arizona. Remarkably, Texas is rapidly expanding its utility-scale PV capacity and may potentially surpass California in the next two years.

 

Rapid Growth in Battery Storage

Battery energy storage has emerged as the dominant and rapidly expanding source of energy storage in the U.S. in recent years. The proportion of battery storage in the country's energy storage capacity has surged dramatically, increasing from a mere 3% in 2017 to a substantial 36% in the first half of 2023.

Offshore chargepoint will power vessels with wind turbine electricity

Offshore Wind Vessel Charging System enables renewable energy offshore charging from wind turbines, delivering clean power to electric vessels and crew transfer ships, boosting range, safety, and net zero maritime operations with reliable, efficient infrastructure.

 

Key Points

A turbine-mounted offshore charger delivering renewable power to electric vessels, extending range and improving safety.

✅ Turbine-mounted, field-proven offshore charging interface

✅ Delivers 100% renewable electricity to electric vessels

✅ Accelerates net zero, cuts maritime fossil fuel use

 

An offshore charging system will power vessels with 100% renewably generated electricity from wind turbines, aligning with projects like battery-electric high-speed ferries now advancing in the United States.

The system, developed by Teesside marine electrical engineering firm MJR Power and Automation, will be presented at the Global Offshore Wind event in Manchester (21-22 June), alongside interest in EV energy storage for buildings that could complement offshore charging solutions.

Known as the Offshore Wind On-Turbine Electrical Vessel Charging System, MJR says the chargepoints will provide efficient, safe and reliable transfer of clean power for crew vehicles and other offshore support vessels, while emerging vehicle-to-grid capacity on wheels concepts highlight the wider role of electric fleets.

“This innovation will break down the existing range barriers and increase the uptake by vessel owners and operators, as demonstrated by electric ships on the B.C. coast moving to fully electric and green propulsion systems for retrofit and new-build vessels,” an announcement said.

“In combination with other field-proven technologies, the charging system will be an important part for government and offshore wind owners and operators to achieve their net zero maritime operations targets, and switch away from fossil fuels, complemented by port initiatives such as all-electric berth at London Gateway now under development. The ability to charge when in the field will significantly accelerate adoption of current emission-free propulsion systems, which will be a major asset for the decarbonisation of the global maritime sector.”

The firm recently announced that construction and in-house testing of the system had been completed. The development project was part of the Clean Maritime Demonstration Competition, funded by the Department for Transport and delivered in partnership with Innovate UK, reflecting wider interest in reversing the charge to the grid for resilient energy systems.

MJR electrical engineer Mohammed Latif said: “Our system will be absolutely crucial in helping governments to deliver on their net zero carbon targets, supported by plans like new UK-Europe interconnectors that strengthen clean energy supply, and I am looking forward to demonstrating how it works and the benefits it offers.”

As part of the project, MJR Power and Automation led a consortium of partners – Ore Catapult, Xceco, Artemis Technologies and Tidal Transit – that all provided expertise.

West Wind Clean Energy Project Launched

Nova Scotia’s West Wind Clean Energy Project aims to harness offshore wind power to deliver renewable electricity, expand transmission infrastructure, and position Canada as a global leader in sustainable energy generation.

 

What is West Wind Clean Energy?

The West Wind Clean Energy Project is Nova Scotia’s $60-billion offshore wind initiative to generate up to 66 GW of clean electricity for Canada’s growing energy needs.

✅ Harnesses offshore wind resources for renewable power generation

✅ Expands grid and transmission infrastructure for clean energy exports

✅ Supports Canada’s transition to a sustainable, low-carbon economy

Nova Scotia has launched one of the most ambitious clean energy projects in Canadian history — a $60-billion plan to build 66 gigawatts (GW) of offshore wind capacity, as countries like the UK expand offshore wind, capable of meeting up to 27 per cent of the nation’s total electricity demand.

Premier Tim Houston unveiled the project, called West Wind, in June, positioning it as a cornerstone of Canada’s broader energy transition and aligning it with Prime Minister Mark Carney’s goal of making the country both a clean energy and conventional energy superpower. Three months later, Carney announced a slate of “nation-building” infrastructure projects the federal government would fast-track. While West Wind was not on the initial list, it was included in a second tier of high-potential proposals still under development.

The plan’s scale is unprecedented for Canada’s offshore energy industry, as organizations like Marine Renewables Canada pivot toward offshore wind to accelerate growth. However, enormous logistical, financial, and market challenges remain. Turbines will not be in the water for years, and the global offshore wind industry itself is facing one of its most difficult periods in over a decade.

“Right now is probably the worst time in 15 years to launch a project like this,” said an executive at a Canadian energy company who requested anonymity. “It’s not Nova Scotia’s fault. It’s just really bad timing.” He pointed to failed offshore wind auctions in Europe, rising costs, and policy reversals in the United States as troubling signals for investors, even as New York’s largest offshore wind project moved ahead this year. “You can’t build the wind and hope the lines come later. You have to build both — together.”

Indeed, transmission infrastructure is emerging as the project’s biggest obstacle. Nova Scotia’s local electricity demand is limited, meaning most of the power would need to be sold to markets in Ontario, Quebec, and New England. Of the $60 billion budgeted for West Wind, $40 billion is allocated to generation, and $20 billion to new transmission — massive sums that require close federal-provincial coordination and long-term investment planning.

Despite the economic headwinds, advocates argue that West Wind could transform Atlantic Canada’s energy landscape and strengthen national energy security, building on recent tidal power investments in Nova Scotia. Peter Nicholson, chair of the Canadian Climate Institute and author of Catching the Wind: How Atlantic Canada Can Become an Energy Superpower, believes the project could redefine Nova Scotia’s role in Canada’s energy transition.

“It’s very well understood where the world is headed,” Nicholson said, noting that wind power is becoming increasingly competitive worldwide. “We’re moving toward an electrical future that’s cleanly generated for economic, environmental, and security reasons. But for that to happen, the economics have to work.” He added that the official “nation-building” designation could give Nova Scotia “a seat at the table” with major utilities in other provinces.

The governments of Canada and Nova Scotia recently issued a notice of strategic direction to the Canada–Nova Scotia Offshore Energy Regulator, aligning with Ottawa’s plan to regulate offshore wind as it begins a prequalification process and designs a call for bids later this year. The initial round will cover just 3 GW of capacity — smaller than the originally envisioned 5 GW — but officials describe it as a first step in a multi-decade plan.

While timing and economics remain uncertain, supporters insist the long-term potential of offshore wind in Nova Scotia is too significant to ignore. As global demand for clean electricity grows and offshore wind moves toward a trillion-dollar global market, they argue, West Wind could help secure Canada’s place as a renewable energy leader — if government and industry can find a way to make the numbers work.

Renewable Electricity Is Coming on Strong

Cascadia electrification accelerates renewable energy with wind and solar, EVs, heat pumps, and grid upgrades across British Columbia, Washington, and Oregon to decarbonize power, buildings, and transport at lower cost while creating jobs.

 

Key Points

Cascadia electrification is the shift to renewable grids, EVs, and heat pumps replacing fossil fuels.

✅ Wind and solar scale fast; gas and coal phase down

✅ EVs and heat pumps cut fuel costs and emissions

✅ Requires grid upgrades, policy, and social acceptance

 

Fifty years ago, a gasoline company’s TV ads showed an aging wooden windmill. As the wind died, it slowed to stillness. The ad asked: “But what do you do when the wind stops?” For the next several decades, fossil fuel providers and big utilities continued to denigrate renewable energy. Even the U.S. Energy Department deemed renewables “too rare, too diffuse, too distant, too uncertain and too ill-timed” to meaningfully contribute, as a top agency analyst put it in 2005.

Today we know that’s not true, especially in British Columbia, Washington and Oregon.

New research shows we could be collectively poised to pioneer a climate-friendly energy future for the globe — that renewable electricity can not only move Cascadia off of fossil fuels, but do so at an affordable price while creating some jobs along the way.

After decades of disinformation, this may sound like a wishful vision. But building a cleaner and more equitable economy — and doing so in just a few decades to head off the worst effects of climate change — is backed by a growing body of regional and international research.

Getting off fossil fuels is “feasible, necessary… and not very expensive” when compared to the earnings of the overall economy, said Jeffrey Sachs, an economist and global development expert at Columbia University.

Much of the confidence about the price tag comes down to this: Innovation and mass production have made wind and solar power installations cheaper than most fossil-fuelled power plants and today’s fastest-growing source of energy worldwide. The key to moving Cascadia’s economies away from fossil fuels, according to the latest research, is building more, prompting power companies to invest in carbon-free electricity as our go-to “fuel.”

However, doing that in time to help head off a cascading climatic crisis by mid-century means the region must take major steps in the next decade to speed the transition, researchers say. And that will require social buy-in.

The new research highlights three mutually supporting strategies that squeeze out fossil fuels:

Chefs and foodies are well-known fans of natural gas. Why, “Cooking with gas” is an expression for a reason. But one trendy Seattle restaurant-bar is getting by just fine with a climate-friendly alternative: electric induction cooktops.

Induction “burners” are just as controllable as gas burners and even faster to heat and cool, but produce less excess heat and zero air pollution. That made a huge difference to chef Stuart Lane’s predecessors when they launched Seattle cocktail bar Artusi 10 years ago.

Using induction meant they could squeeze more tables into the tight space available next door to Cascina Spinasse — their popular Italian restaurant in Seattle’s vibrant Capitol Hill neighborhood — and lowered the cost of expanding.

Rather than igniting a fossil fuel to roast the surface of pots and pans, induction burners generate a magnetic field that heats metal cookware from inside. For people at home, forgoing gas eliminates combustion by-products, which means fewer asthma attacks and other health impacts.

For Artusi, it eliminated the need for a pricey hood and fans to continuously pump fumes and heat out and pull fresh air in. That made induction the cheaper way to go, even though induction cooktops cost more than conventional gas ranges.

Over the years, they’ve expanded the menu because even guests who come for the signature Amari cocktails often stay for the handmade pasta, meatballs and seasonal sauces. So the initial pair of induction burners has multiplied to nine. Yet Artusi retains a cleaner, quieter and more intimate atmosphere. Yet thanks largely to the smaller fans, “it’s not as chaotic,” said Lane.

And Lane adds, it feels good to be cooking on electricity — which in Seattle proper is about 90 per cent renewable — rather than on a fossil fuel that produces climate-warming greenhouse gases. “You feel like you’re doing something right,” he said.

Lane says he wouldn’t be surprised if induction is the new normal for chefs entering the trade 10 years from now. “They probably would cook with gas and say, ‘Damn it’s hot in here!’” — Peter Fairley

increasing energy efficiency to trim the amount of power we need,

boosting renewable energy to make it possible to turn off climate-wrecking fossil-fuel plants, and

plugging as much stuff as possible into the electrical grid.
Recent studies in B.C. and Washington state, and underway for Oregon, point to efficiency and electrification as the most cost-effective route to slashing emissions while maintaining lifestyles and maximizing jobs. A recent National Academies of Science study reached the same conclusion, calling electrification the core strategy for an equitable and economically advantageous energy transition, while abroad New Zealand's electrification push is asking whether electricity can replace fossil fuels in time.

However, technologies don’t emerge in a vacuum. The social and economic adjustments required by the wholesale shift from fossil fuels that belch climate-warming carbon emissions to renewable power can still make or break decarbonization, according to Jim Williams, a University of San Francisco energy expert whose simulation software tools have guided many national and regional energy plans, including two new U.S.-wide studies, a December 2020 analysis for Washington state and another in process for Oregon.

Williams points to vital actions that are liable to rile up those who lose money in the deal. Steps like letting trees grow many decades older before they are cut down, so they can suck up more carbon dioxide — which means forgoing quicker profits from selling timber. Or convincing rural communities and conservationists that they should accept power-transmission lines crossing farms and forests.

“It’s those kinds of policy questions and social acceptance questions that are the big challenges,” said Williams.

Washington, Oregon and B.C. already mandate growing supplies of renewable power and help cover the added cost of some electric equipment, and across the border efforts at cleaning up Canada's electricity are critical to meeting climate pledges. These include battery-powered cars, SUVs and pickups on the road. Heat pumps — air conditioners that run in reverse to push heat into a building — can replace furnaces. And, at industrial sites, electric machines can take the place of older mechanical systems, cutting costs and boosting reliability.

As these options drop in price they are weakening reliance on fossil fuels — even among professional chefs who’ve long sworn by cooking with gas (see sidebar: Cooking quick, clean and carbon-free).

“For each of the things that we enjoy and we need, there’s a pathway to do that without producing any greenhouse gas emissions,” said Jotham Peters, managing partner for Vancouver-based energy analysis firm Navius Research, whose clients include the B.C. government.


What the modelling tells us

Key to decarbonization planning for Cascadia are computer simulations of future conditions known as models. These projections take electrification and other options and run with them. Researchers run dozens of simulated potential future energy scenarios for a given region, tinkering with different variables: How much will energy demand grow? What happens if we can get 80 per cent of people into electric cars? What if it’s only 50 per cent? And so on.

Accelerating the transition requires large investments, this modelling shows. Plugging in millions of vehicles and heat pumps demands both brawnier and more flexible power systems, including more power lines and other infrastructure such as bridging the Alberta-B.C. electricity gap that communities often oppose. That demands both stronger policies and public acceptance. It means training and apprenticeships for the trades that must retrofit homes, and ensuring that all communities benefit — especially those disproportionately suffering from energy-related pollution in the fossil fuel era.

Consensus is imperative, but the new studies are bound to spark controversy. Because, while affordable, decarbonization is not free.

Projections for British Columbia and Washington suggest that decarbonizing Cascadia will spur extra job-stimulating growth. But the benefits and relatively low net cost mask a large swing in spending that will create winners and losers, and without policies to protect disadvantaged communities from potential energy cost increases, could leave some behind.

By 2030, the path to decarbonization shows Washingtonians buying about $5 billion less worth of natural gas, coal and petroleum products, while putting even more dollars toward cleaner vehicles and homes. No surprise then that oil and gas interests are attacking the new research.

And the research shows a likely economic speed bump around 2030. Economic growth would slow due to increased energy costs as economies race to make a sharp turn toward pollution reductions after nearly a decade of rising greenhouse gas emissions.

“Meeting that 2030 target is tough and I think it took everybody a little bit by surprise,” said Nancy Hirsh, executive director of the Seattle-based NW Energy Coalition, and co-chair of a state panel that shaped Washington’s recent energy supply planning.

But that’s not cause to ease up. Wait longer, says Hirsh, and the price will only rise.


Charging up

What most drives Cascadia’s energy models toward electrification is the dropping cost of renewable electricity.

Take solar energy. In 2010, no large power system in the world got more than three per cent of its electricity from solar. But over the past decade, solar energy’s cost fell more than 80 per cent, and by last year it was delivering over nine per cent of Germany’s electricity and over 19 per cent of California’s.

Government mandates and incentives helped get the trend started, and Canada's electricity progress underscores how costs continue to fall. Once prohibitively expensive, solar’s price now beats nuclear, coal and gas-fired power, and it’s expected to keep getting cheaper. The same goes for wind power, whose jumbo jet-sized composite blades bear no resemblance to the rickety machines once mocked by Big Oil.

In contrast, cleaning up gas- or coal-fired power plants by equipping them to capture their carbon pollution remains expensive even after decades of research and development and government incentives. Cost overruns and mechanical failures recently shuttered the world’s largest “low-carbon” coal-fired power plant in Texas after less than four years of operation.

Retrofits enabled this coal-fired plant in Texas to capture some of its carbon dioxide pollution, which was then injected into aging oil wells to revive production. But problems made the plant’s coal-fired power — which is being priced out by renewable energy — even less competitive and it was shut down after three years in 2020. Photo by NRG Energy.
Innovation and incentives are also making equipment that plugs into the grid cheaper. Electric options are good and getting better with a push from governments and a self-reinforcing cycle of performance improvement, mass production and increased demand.

Battery advances and cost cuts over the past decade have made owning an electric car cheaper, fuel included, than conventional cars. Electric heat pumps may be the next electric wave. They’re three to four times more efficient than electric baseboard heaters, save money over natural gas in most new homes, and work in Cascadia’s coldest zones.

Merran Smith, executive director of the Vancouver-based non-profit Clean Energy Canada, says that — as with electric cars five years ago — people don’t realize how much heat pumps have improved. “Heat pumps used to be big huge noisy things,” said Smith. “Now they’re a fraction of the size, they’re quiet and efficient.”

Electrifying certain industrial processes can also cut greenhouse gases at low cost. Surprisingly, even oil and gas drilling rigs and pipeline compressors can be converted to electric. Provincial utility BC Hydro is building new transmission lines to meet anticipated power demand from electrification of the fracking fields in northeastern British Columbia that supply much of Cascadia’s natural gas.


Simulating low-carbon living

The computer simulation tools guiding energy and climate strategies, unlike previous models that looked at individual sectors, take an economy-wide view. Planners can repeatedly run scenarios through sophisticated software, tinkering with their assumptions each time to answer cross-cutting questions such as: Should the limited supply of waste wood from forestry that can be sustainably removed from forests be burned in power plants? Or is it more valuable converted to biofuel for airplanes that can’t plug into the grid?

Evolved Energy Research, a San Francisco-based firm, analyzed the situation in Washington. Its algorithms are tuned using data about energy production and use today — down to the number and types of furnaces, stovetops or vehicles. It has expert assessments of future costs for equipment and fuels. And it knows the state’s mandated emissions targets.

Researchers run the model myriad times, simulating decisions about equipment and fuel purchases — such as whether restaurants stick with gas or switch to electric induction “burners” as their gas stoves wear out. The model finds the most cost-effective choices by homes and businesses that meet the state’s climate goals.

For Seattle wine bar Artusi, going with electric induction cooktops meant they could squeeze more tables into a tight, comfortable space. Standard burners cost less but would have required noisy, pricey fume hoods and fans to suck out the pollutants. For more, see sidebar. Photo: InvestigateWest.
Rather than accepting that optimal scenario and calling it a day, modellers account for uncertainty in their estimates of future costs by throwing in various additional constraints and rerunning the model.

That probing shows that longer reliance on climate-warming natural gas and petroleum fuels increases costs. In fact, all of the climate-protecting scenarios achieve Washington’s goals at relatively low cost, compared to the state’s historic spending on energy.

The end result of these scenarios are net-zero carbon emissions in 2050, echoing Canada's race to net-zero and the growing role of renewable energy, in which a small amount of emissions remaining are offset by rebounding forests or equipment that scrubs CO2 from the air.

But the seeds of that transformation must be sown by 2030. The scenarios identify common strategies that the state can pursue with low risk of future regrets.

One no brainer is to rapidly add wind and solar power to wring out CO2 emissions from Washington’s power sector. The projections end coal-fired power by 2025, as required by law, but also show that, with grid upgrades, gas-fired power plants that produce greenhouse gas emissions can stay turned off most of the time. That delivers about 16.2 million of the 44.8 million metric tons of CO2 emissions cut required by 2030 under state law.

All of the Washington scenarios also jack up electricity consumption to power cars and heating. By 2050, Washington homes and businesses would draw more than twice as much power from the grid as they did last year, meaning climate-friendly electricity is displacing climate-unfriendly gasoline, diesel fuel and natural gas. In the optimal case, electricity meets 98 per cent of transport energy in 2050, and over 80 per cent of building energy use.

By 2050, the high-electrification scenarios would create over 60,000 extra jobs across the state, as replacing old and inefficient equipment and construction of renewable power plants stimulates economic growth, according to projections from Washington, D.C.-based FTI Consulting. Scenarios with less electrification require more low-carbon fuels that cut emissions at higher cost, and thus create 15,000 to 35,000 fewer jobs.

Much of the new employment comes in middle-class positions — including about half of the total in construction — leading to big boosts in employment income. Washingtonians earn over $7 billion more in 2050 under the high-electrification scenarios, compared to a little over $5 billion if buildings stick with gas heating through 2050 and less than $2 billion with extra transportation fuels.


Rocketing to 2030

Evolved Energy’s electrification-heavy decarbonization pathways for Washington dovetail with a growing body of international research, such as that National Academy of Sciences report and a major U.S. decarbonization study led by Princeton University, and in Canada debates like Elizabeth May's 2030 renewable grid goal are testing feasibility. (See Grist’s 100 per cent Clean Energy video for a popularized view of similar pathways to slash U.S. carbon emissions, informed by Princeton modeller Jesse Jenkins.)
