Space-Based Solar Power enables wireless energy transfer from orbital solar arrays, using microwave beaming to rectennas on Earth, delivering clean baseload power beyond weather and night limits, as demonstrated by Caltech and NASA.

 

Key Points

Space-based solar power beams microwaves from arrays to rectennas, delivering clean electricity beyond weather and night.

✅ Caltech demo proved wireless power transfer in space.

✅ Microwaves beam to rectennas for grid-scale clean energy.

✅ Operates above clouds, enabling continuous baseload supply.

 

Ali Hajimiri thinks there’s a better way to power the planet — one that’s not getting the attention it deserves. The Caltech professor of electrical engineering envisages thousands of solar panels floating in space, unobstructed by clouds and unhindered by day-night cycles, effectively generating electricity from the night sky for continuous delivery, wirelessly transmitting massive amounts of energy to receivers on Earth.

This year, that vision moved closer to reality when Mr. Hajimiri, together with a team of Caltech researchers, proved that wireless power transfer in space was possible: Solar panels they had attached to a Caltech prototype in space successfully converted electricity into microwaves and beamed those microwaves to receivers, as a demonstration of beaming power from space to devices about a foot away, lighting up two LEDs.

The prototype also beamed a tiny but detectable amount of energy to a receiver on top of their lab’s building in Pasadena, Calif. The demonstration marks a first step in the wireless transfer of usable power from space to Earth, and advances in low-cost solar batteries could help store and smooth that power flow — a power source that Mr. Hajimiri believes will be safer than direct sun rays. “The beam intensity is to be kept less than solar intensity on earth,” he said.

Finding alternative energy sources is one of the topics that will be discussed by leaders in business, science and public policy, including wave energy, during The New York Times Climate Forward event on Thursday. The Caltech demonstration was a significant moment in the quest to realize space-based solar power, amid policy moves such as a proposed tenfold increase in U.S. solar that would remake the U.S. electricity system — a clean energy technology that has long been overshadowed by other long-shot clean energy ideas, such as nuclear fusion and low-cost clean hydrogen.

If space-based solar can be made to work on a commercial scale, said Nikolai Joseph, a NASA Goddard Space Flight Center senior technology analyst, and integrate with peer-to-peer energy sharing networks, such stations could contribute as much as 10 percent of global power by 2050.

The idea of space-based solar energy has been around since at least 1941, when the science-fiction writer Isaac Asimov set one of his short stories, “Reason,” on a solar station that beamed energy by microwaves to Earth and other planets.

In the 1970s, when a fivefold increase in oil prices sparked interest in alternative energy, NASA and the Department of Energy conducted the first significant study on the topic. In 1995, under the direction of the physicist John C. Mankins, NASA took another look and concluded that investments in space-launch technology were needed to lower the cost and move closer to cheap abundant electricity before space-based solar power could be realized.

“There was never any doubt about it being technically feasible,” said Mr. Mankins, now president of Artemis Innovation Management Solutions, a technology consulting group. “The cost was too prohibitive.”

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.)

Renewables became the second-most prevalent U.S. electricity source in 2020

2020 U.S. Renewable Electricity Generation set a record as wind, solar, hydro, biomass, and geothermal produced 834 billion kWh, surpassing coal and nuclear, second only to natural gas in nationwide power output.

 

Key Points

The record year when renewables made 834 billion kWh, topping coal and nuclear in U.S. electricity.

✅ Renewables supplied 21% of U.S. electricity in 2020

✅ Coal output fell 20% y/y; nuclear slipped 2% on retirements

✅ EIA forecasts renewables rise in 2021-2022; coal rebounds

 

In 2020, renewable energy sources (including wind, hydroelectric, solar, biomass, and geothermal energy) generated a record 834 billion kilowatthours (kWh) of electricity, or about 21% of all the electricity generated in the United States. Only natural gas (1,617 billion kWh) produced more electricity than renewables in the United States in 2020. Renewables surpassed both nuclear (790 billion kWh) and coal (774 billion kWh) for the first time on record. This outcome in 2020 was due mostly to significantly less coal use in U.S. electricity generation and steadily increased use of wind and solar generation over time, amid declining consumption trends nationwide.

In 2020, U.S. electricity generation from coal in all sectors declined 20% from 2019, while renewables, including small-scale solar, increased 9%. Wind, currently the most prevalent source of renewable electricity in the United States, grew 14% in 2020 from 2019, and the EIA expects solar and wind to be larger sources in summer 2022, reflecting continued growth. Utility-scale solar generation (from projects greater than 1 megawatt) increased 26%, and small-scale solar, such as grid-connected rooftop solar panels, increased 19%, while early 2021 January power generation jumped year over year.

Coal-fired electricity generation in the United States peaked at 2,016 billion kWh in 2007 and much of that capacity has been replaced by or converted to natural gas-fired generation since then. Coal was the largest source of electricity in the United States until 2016, and 2020 was the first year that more electricity was generated by renewables and by nuclear power than by coal (according to our data series that dates back to 1949). Nuclear electric power declined 2% from 2019 to 2020 because several nuclear power plants retired and other nuclear plants experienced slightly more maintenance-related outages.

We expect coal-fired generation to increase in the United States during 2021 as natural gas prices continue to rise and as coal becomes more economically competitive. Based on forecasts in our Short-Term Energy Outlook (STEO), we expect coal-fired electricity generation in all sectors in 2021 to increase 18% from 2020 levels before falling 2% in 2022. We expect U.S. renewable generation across all sectors to increase 7% in 2021 and 10% in 2022, and in 2021, non-fossil fuel sources accounted for about 40% of U.S. electricity. As a result, we forecast coal will be the second-most prevalent electricity source in 2021, and renewables will be the second-most prevalent source in 2022. We expect nuclear electric power to decline 2% in 2021 and 3% in 2022 as operators retire several generators.

UK Renewable energy projects worth billions stuck on hold

UK Renewable Grid Connection Delays threaten the 2035 zero-carbon electricity target as National Grid queues stall wind and solar projects, investors, and infrastructure, slowing clean energy deployment, curtailing capacity build-out, and risking net-zero progress.

 

Key Points

Prolonged National Grid queues delaying wind and solar connections, jeopardizing the UK's 2035 clean power target.

✅ Up to 15-year waits for grid connections

✅ Over £200bn projects stuck in the queue

✅ Threatens zero-carbon electricity by 2035

 

The UK currently has a 2035 target for 100% of its electricity to be produced without carbon emissions, while Ireland's green electricity progress offers a nearby benchmark within the next four years.

But meeting the target will require a big increase in the number of renewable projects across the country. It is estimated as much as five times more solar and four times as much wind is needed, with growth in UK offshore wind expected to play a key role here.

The government and private investors have spent £198bn on renewable power infrastructure since 2010, alongside European wind investments recorded last year. But now energy companies are warning that significant delays to connect their green energy projects to the system will threaten their ability to bring more green power online.

A new wind farm or solar site can only start supplying energy to people's homes once it has been plugged into the grid.

Energy companies like Octopus Energy, one of Europe's largest investors in renewable energy, say they have been told by National Grid that they need to wait up to 15 years for some connections, even as a new 10 GW contract aims to speed UK grid additions - far beyond the government's 2035 target.

'Longest grid queues in Europe'
There are currently more than £200bn worth of projects sitting in the connections queue, the BBC has calculated.

Around 40% of them face a connection wait of at least a year, according to National Grid's own figures. That represents delayed investments worth tens of billions of pounds, reflecting stalled grid spending that slows renewable rollouts.

"We currently have one of the longest grid queues in Europe," according to Zoisa North-Bond, chief executive of Octopus Energy Generation.

The problem is so many new renewable projects are applying for connections, the grid cannot keep up with required network expansion such as new pylons in Scotland being discussed nationwide.

The system was built when just a few fossil fuel power plants were requesting a connection each year, but now there are 1,100 projects in the queue, a challenge mirrored by U.S. grid hurdles in moving toward 100% renewables today.

Electric vehicle owners can get paid to sell electricity back to the grid

Ontario EV V2G Pilots enable bi-directional charging, backup power, and grid services with IESO, Toronto Hydro, and Hydro One, linking energy storage, solar, blockchain apps, and demand response incentives for smarter electrification.

 

Key Points

Ontario EV V2G pilots test bidirectional charging and backup power to support grid services with apps and incentives.

✅ Tests Nissan Leaf V2H backup with Hydro One and Peak Power.

✅ Integrates solar, storage, blockchain apps via Sky Energy and partners.

✅ Pilots demand response apps in Toronto and Waterloo utilities.

 

Electric vehicle owners in Ontario may one day be able to use the electricity in their EVs instead of loud diesel or gas generators to provide emergency power during blackouts. They could potentially also sell back energy to the grid when needed. Both are key areas of focus for new pilot projects announced this week by Ontario’s electricity grid operator and partners that include Toronto Hydro and Ontario Hydro.

Three projects announced this week will test the bi-directional power capabilities of current EVs and the grid, all partially funded by the Independent Electricity System Operator (IESO) of Ontario, with their announcement in Toronto also attended by Ontario Energy Minister Todd Smith.

The first project is with Hydro One Networks and Peak Power, which will use up to 10 privately owned Nissan Leafs to test what is needed technically to support owners using their cars for vehicle-to-building charging during power outages. It will also study what type of financial incentives will convince EV owners to provide backup power for other users, and therefore the grid.

A second pilot program with solar specialist Sky Energy and engineering firm Hero Energy will study EVs, energy storage, and solar panels to further examine how consumers with potentially more power to offer the grid could do it securely, in part using blockchain technology. York University and Volta Research are other partners in the program, which has already produced an app that can help drivers choose when and how much power to provide the grid — if any.

The third program is with local utilities in Toronto and Waterloo, Ont., and will test a secure digital app that helps EV drivers see the current demands on the grid through improved grid coordination mechanisms, and potentially price an incentive to EV drivers not to charge their vehicles for a few hours. Drivers could also be actively further paid to provide some of the charge currently in their vehicle back to the grid.

It all adds up to $2.7 million in program funding from IESO ($1.1 million) and the associated partners.

“An EV charged in Ontario produces roughly three per cent of emissions of a gas fuelled car,” said IESO’s Carla Nell, vice-president of corporate relations and innovation at the announcement near Peak Power chargers in downtown Toronto. “We know that Ontario consumers are buying EVs, and expected to increase tenfold — so we have to support electrification.”

If these types of programs sound familiar, it may be because utilities in Ontario have been testing such vehicle-to-grid technologies soon after affordable EVs became available in the fall of 2011. One such program was run by PowerStream, now the called Alectra, and headed by Neetika Sathe, who is now Alectra’s vice-president of its Green Energy and Technology (GRE&T) Centre in Guelph, Ont.

The difference between now and those tests in the mid-2010s is that the upcoming wave of EV sales can be clearly seen on the horizon, and California's grid stability work shows how EVs can play a larger role.

“We can see the tsunami now,” she said, noting that cost parity between EVs and gas vehicles is likely four or five years away — without government incentives, she stressed. “Now it’s not a question of if, it’s a question of when — and that when has received much more clarity on it.”

Sathe sees a benefit in studying all these types of bi-directional power-flowing scenarios, but notes that they are future scenarios for years in the future, especially since bi-directional charging equipment — and the vehicles with this capability — are pricey, and largely still not here. What she believes is much closer is the ability to automatically communicate what the grid needs with EV drivers, as Nova Scotia Power pilots integration, and how they could possibly help. For a price, of course.

“If I can set up a system that says ‘oh, the grid is stressed, can you not charge for the next two hours? And here’s what we’ll offer to you for that,’ that’s closer to low-hanging fruit,” she said, noting that Alectra is currently testing out such systems. “Think of it the same way as offering your car for Uber, or a room on Airbnb.”

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.

Rhode Island 100% Renewable Electricity by 2030 outlines pathways via offshore wind, retail solar, RECs, and policy reforms, balancing decarbonization, grid reliability, economics, and equity to close a 4,600 GWh supply gap affordably.

 

Key Points

A statewide plan to meet all electricity demand with renewables by 2030 via offshore wind, solar, and REC policies.

✅ Up to 600 MW offshore wind could add 2,700 GWh annually

✅ Retail solar programs may supply around 1,500 GWh per year

✅ Amend RES to retain RECs and align supply with real-time demand

 

A year ago, Executive Order 20-01 cemented in a place Rhode Island’s goal to meet 100% of the state’s electricity demand with renewable energy by 2030, aligning with the road to 100% renewables seen across states. The Rhode Island Office of Energy Resources (OER) worked through the year on an economic and energy market analysis, and developed policy and programmatic pathways to meet the goal.

In the most recent development, OER and The Brattle Group co-authored a report detailing how this goal will be achieved, The Road to 100% Renewable Electricity – The Pathways to 100%.

The report includes economic analysis of the key factors that will guide Rhode Island as it accelerates adoption of carbon-free renewable resources, complementing efforts that are tracking progress on 100% clean energy targets nationwide.

The pathway rests on three principles: decarbonization, economics and policy implementation, goals echoed in Maine’s 100% renewable electricity target planning.

The report says the state needs to address the gap between projected electricity demand in 2030 and projected renewable generation capacity. The report predicts a need for 4,600 GWh of additional renewable energy to close the gap. Deploying that much capacity represents a 150% increase in the amount of renewable energy the state has procured to date. The final figure could as much as 600-700 GWh higher or lower.

Addressing the gap
The state is making progress to close the gap.

Rhode Island recently announced plans to solicit proposals for up to 600 MW of additional offshore wind resources. A draft request for proposals (RFP) is expected to be filed for regulatory review in the coming months, aligning with forecasts that one-fourth of U.S. electricity will soon be supplied by renewables as markets mature. Assuming the procurement is authorized and the full 600 MW is acquired, new offshore wind would add about 2,700 GWh per year, or about 35% of 2030 electricity demand.

Beyond this offshore wind procurement, development of retail solar through existing programs could add another 1,500 GWh per year. That leaves a smaller–though still sizable–gap of around 400 GWh per year of renewable electricity.

All this capacity will come with a hefty price. The report finds that rate impacts would likely boost e a typical 2030 monthly residential bill by about $11 to $14 with utility-scale renewables, or by as much as $30 if the entire gap were to be filled with retail solar.

The upside is that if the renewable resources are developed in-state, the local economic activity would boost Rhode Island’s gross domestic product and local jobs, especially when compared to procuring out-of-state resources or buying Renewable Energy Credits (RECs), and comes as U.S. renewable electricity surpassed coal in 2022 across the national grid.

Policy recommendations
One policy item that has to be addressed is the state’s Renewable Energy Standard (RES), which currently calls for meeting 38.5% of electricity deliveries with renewables by 2035, even as the federal 2035 clean electricity goal sets a broader benchmark for decarbonization. For example, RES compliance at present does not require the physical procurement of power produced by renewable energy facilities. Instead, electricity providers meet their requirements by purchasing RECs.

The report recommends amending the state’s RES to seek methods by which Rhode Island can retain all of the RECs procured through existing policy and program channels, along with RECs resulting from ratepayer investment in net metered projects, while Nevada’s 50% by 2030 RPS provides a useful interim comparison.

The report also recognizes that the RES alone is unlikely to drive sufficient investment renewable generation and should be paired with programs and policies to ensure sufficient renewable generation to meet the 100% goal. The state also needs to address the RECs created by behind-the-meter systems that add mechanisms to better match the timing of renewable energy generation with real-time demand. The policy would have the 100% RES remain in effect beyond 2030 and also match shifts in energy demand, particularly as other parts of the economy electrify.

Fostering equity
The state also is putting a high priority on making sure the transition to renewables is an equitable one.

The report recommends partnering with and listening to frontline communities about their needs and goals in the clean energy transition. This will include providing traditionally underserved communities with expert consultation to help guide decision making. The report also recommends holding listening sessions to increase accessibility to and understanding of energy system basics.
