US Moving Towards 30% Electricity From Wind & Solar

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.”

Ontario EV Charging Network Delay highlights permitting hurdles, grid limitations, and public-private rollout challenges across 250 sites, as two-thirds of 475 chargers go live while full provincewide infrastructure deployment slips to fall.

Key Points

A provincial rollout setback where permitting and grid issues delay full activation of Ontario's 475 public EV chargers.

✅ Two-thirds of 475 chargers live by the initial deadline

✅ Remaining stations expected online by fall

✅ Delays tied to permits, site conditions, and grid capacity

The Ontario government admitted Wednesday that it will fall short of meeting its deadline this Friday of creating a network of 475 electric vehicle charging stations in 250 locations across the province, and it's blaming unforeseen problems for the delay.

"We know some of our partners have encountered difficulties around permitting and some of the technical aspects of having some of the chargers up and running, even as we work to make it easier to build EV charging stations across Ontario," said Transportation Minister Steven Del Duca.

Two-thirds of the network will be live on Friday with the rest of the stations expected to be up and running by fall, according to the Ministry of Transportation. 

"Each of our partners' individual charging stations are subject to different site conditions, land ownership, municipal permitting, electrical grid limitations, as seen in regions where EV infrastructure lags, and other factors which have influenced timelines," said Bob Nichols, senior media liaison officer for the Transportation Ministry, in a statement. 

Because the stations are located in various community centres, retail outlets and other public spaces, Del Duca said the government's public and private sector partners are facing challenges in obtaining permits but are "motivated to get it right."

Cara Clairman, president and CEO of Plug'n Drive, an organization dedicated to accelerating the rollout of electric vehicles, says she isn't concerned about the delay.

"It was a pretty aggressive timeline. The EV community is pretty happy with the fact that it is going to happen. It might be slightly delayed but I think overall the mood is positive," she said.

Clairman said there are now more than 10,000 electric vehicles in the province and that more growth is expected as Ontario's next EV wave emerges in the market. She doesn't believe the delay in the rollout of charging stations will deter anyone from purchasing electric vehicles, even amid EV shortages and wait times in some segments.

"It certainly does help to persuade new folks to get on board but I think since they know it is coming, I don't see it having a big impact." 

Horwath not surprised

NDP Leader Andrea Horwath said she's not surprised the government didn't meet its target.

"You shouldn't be making these promises if you can't fulfil them, that's the bottom line," she said. "Let's be realistic with
what you're able to achieve."

Progressive Conservative transportation critic Michael Harris suggested the Liberals don't have their priorities straight when it comes to electric vehicles.

"I think the focus for Kathleen Wynne was handing out $14,000 rebates to owners of Teslas, while they really should have been focusing their time and energy on ensuring that the infrastructure for electric vehicles has actually been rolled out," Harris said.

Covering every corner

Del Duca said the ministry has seen "some fairly tremendous success" despite the delays but that there have been a few challenges in building a network that ranges across the province, even as N.L.'s first fast-charging network is touted as just the beginning elsewhere. 

"We definitely want to make sure we're building a network that covers every corner of Ontario. Yes, we have some challenges and we are slightly delayed," the minister said.

"We anticipate being able to provide more resources in the coming months to continue to deploy an even broader network of charging infrastructure, including in northern Ontario."

Del Duca said a map on the ministry's website showing where the charging stations are installed should be updated in the next few days.

Premier Wynne committed to building a charging network for electric vehicles across Ontario at the 2015 climate change talks in Paris.

The $20 million in funding for the charging stations comes from Ontario's $325 million Green Investment Fund, which supports projects that fight climate change.

Canada Electricity Decarbonization Costs indicate challenging greenhouse gas reductions across a fragmented grid, with wind, solar, nuclear, and natural gas tradeoffs, significant GDP impacts, and Net Zero targets constrained by intermittency and limited interties.

Key Points

Costs to cut power CO2 via wind, solar, gas, and nuclear, considering grid limits, intermittency, and GDP impacts.

✅ Alberta model: eliminate coal; add wind, solar, gas; 26-40% CO2 cuts

✅ Nuclear option enables >75% cuts at higher but feasible system costs

✅ National costs 1-2% GDP; reserves, transmission, land, and waste not included

Along with many western developed countries, Canada has pledged to reduce its greenhouse gas emissions by 40–45 percent by 2030 from 2005 emissions levels, and to achieve net-zero emissions by 2050.

This is a huge challenge that, when considered on a global scale, will do little to stop climate change because emissions by developing countries are rising faster than emissions are being reduced in developed countries. Even so, the potential for achieving emissions reduction targets is extremely challenging as there are questions as to how and whether targets can be met and at what cost. Because electricity can be produced from any source of energy, including wind, solar, geothermal, tidal, and any combustible material, climate change policies have focused especially on nations’ electricity grids, and in Canada cleaning up electricity is viewed as critical to meeting climate pledges.

Canada’s electricity grid consists of ten separate provincial grids that are weakly connected by transmission interties to adjacent grids and, in some cases, to electricity systems in the United States. At times, these interties are helpful in addressing small imbalances between electricity supply and demand so as to prevent brownouts or even blackouts, and are a source of export revenue for provinces that have abundant hydroelectricity, such as British Columbia, Manitoba, and Quebec.

Due to generally low intertie capacities between provinces, electricity trade is generally a very small proportion of total generation, though electricity has been a national climate success in recent years. Essentially, provincial grids are stand alone, generating electricity to meet domestic demand (known as load) from the lowest cost local resources.

Because climate change policies have focused on electricity (viz., wind and solar energy, electric vehicles), and Canada will need more electricity to hit net-zero according to the IEA, this study employs information from the Alberta electricity system to provide an estimate of the possible costs of reducing national CO2 emissions related to power generation. The Alberta system serves as an excellent case study for examining the potential for eliminating fossil-fuel generation because of its large coal fleet, favourable solar irradiance, exceptional wind regimes, and potential for utilizing BC’s reservoirs for storage.

Using a model of the Alberta electricity system, we find that it is infeasible to rely solely on renewable sources of energy for 100 percent of power generation—the costs are prohibitive. Under perfect conditions, however, CO2 emissions from the Alberta grid can be reduced by 26 to 40 percent by eliminating coal and replacing it with renewable energy such as wind and solar, and gas, but by more than 75 percent if nuclear power is permitted. The associated costs are estimated to be some $1.4 billion per year to reduce emissions by at most 40 percent, or $1.9 billion annually to reduce emissions by 75 percent or more using nuclear power (an option not considered feasible at this time).

Based on cost estimates from Alberta, and Ontario’s experience with subsidies to renewable energy, and warnings that the switch from fossil fuels to electricity could cost about $1.4 trillion, the costs of relying on changes to electricity generation (essentially eliminating coal and replacing it with renewable energy sources and gas) to reduce national CO2 emissions by about 7.4 percent range from some $16.8 to $33.7 billion annually. This constitutes some 1–2 percent of Canada’s GDP.

The national estimates provided here are conservative, however. They are based on removing coal-fired power from power grids throughout Canada. We could not account for scenarios where the scale of intermittency turned out worse than indicated in our dataset—available wind and solar energy might be lower than indicated by the available data. To take this into account, a reserve market is required, but the costs of operating such a capacity market were not included in the estimates provided in this study. Also ignored are the costs associated with the value of land in other alternative uses, the need for added transmission lines, 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.

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.

US Renewable Energy Cost Advantage signals cheaper utility-scale solar and onshore wind versus natural gas, with LCOE declines, tax credits, and climate policy cutting electricity costs for utilities and grids across the United States.

Key Points

Cheaper solar and wind than natural gas, driven by LCOE drops, tax credits, and policy, lowering US electricity costs.

✅ Utility-scale solar is about one-third cheaper than gas

✅ Onshore wind costs roughly 44 percent less than natural gas

✅ Policy and tax credits accelerate renewables and cut power prices

Natural gas’s dominance as power-plant fuel in the US is fading fast as the cost of electricity generated by US wind and solar projects tumbles and as wind and solar surpass coal in the generation mix, according to Guggenheim Securities.

Utility-scale solar is now about a third cheaper than gas-fired power, while onshore wind is about 44% less expensive, Guggenheim analysts led by Shahriar Pourreza said Monday in a note to clients, a dynamic consistent with falling wholesale power prices in several markets today. 

“Solar and wind now present a deflationary opportunity for electric supply costs,” the analysts said, which “supports the case for economic deployment of renewables across the US,” as the country moves toward 30% wind and solar and one-fourth of total generation in the near term.

Gas prices have surged amid a global supply crunch after Russia’s invasion of Ukraine, while tax-credit extensions and sweeping US climate legislation have brought down the cost of wind and solar, even as renewables surpassed coal in 2022 nationwide. Renewables-heavy utilities like NextEra Energy Inc. and Allete Inc. stand to benefit, and companies that can boost spending on wind and solar, as wind, solar and batteries dominate the 2023 pipeline, will also see faster growth, Guggenheim said.

Lion Electric Battery Plant Quebec secures near $100M public investment for an automated battery-pack assembly in Saint-Jérôme, fueling EV manufacturing, R&D, local supply chains, and heavy-duty zero-emission vehicle competitiveness and jobs.

Key Points

Automated battery-pack plant in Saint-Jérôme boosting EV manufacturing and strengthening Quebec's supply chain.

✅ $100M joint federal-provincial investment announced

✅ 135 jobs in 2023; 150 more long-term positions

✅ R&D hub to enhance heavy-duty EV battery performance

Canadian Prime Minister of Canada, Justin Trudeau, and the Premier of Quebec, François Legault, have announced an equal investment totalling nearly $100 million to Lion Electric, as a B.C. battery plant announcement has done in another province, for the establishment of a highly automated battery-pack assembly plant in Saint–Jérôme, in the Laurentians. This project, valued at nearly $185 million, will create 135 jobs when construction of the plant is completed in 2023. It is also expected that 150 additional jobs will be created over the longer term.

For the announcement, Mr. Trudeau and Mr. Legault were accompanied by the Minister of Innovation, Science and Industry, François-Philippe Champagne, by Quebec's Minister of Economy and Innovation, Pierre Fitzgibbon, and by Marc Bédard, President and Founder of Lion Electric.

The battery packs assembled at the new plant will be used in Lion Electric vehicles. This strategic investment will allow the company to improve its cost structure, and better control the design and shape of its batteries, making it more competitive in the heavy-duty electric vehicle market, as EV assembly deals put Canada in the race. Ultimately, the company will be able to increase the volume of its vehicle production. Lion Electric will be the first Canadian manufacturer of medium and heavy-duty vehicles to have state-of-the-art, automated battery-pack manufacturing facilities.

The company will also establish a research and development innovation centre within its manufacturing plant, which will allow it to test and refine products for future use, including batteries for emergency vehicles such as ambulances. The company will test innovations from research and development, including energy storage capacity and battery performance. The results will make these products more competitive in the North American market, where a Niagara Region battery plant signals growing demand.

The company said it expects to employ 135 people at the plant when it is operational by 2023. It also plans to invest in a research and development facility that could create a number of spinoff jobs.

"When we talk about an economic recovery that's good for workers, for families and for the environment, this is exactly the kind of project we mean," Trudeau said at a news conference in Montreal.

It was the prime minister's first trip to Montreal in more than a year. He said one of the reasons he decided to attend the announcement was to illustrate the importance of the green economy and how Canada can capitalize on the U.S. EV pivot for future job growth.

The project also aligns with the Legault government's desire to create a supply chain within Quebec that is able to feed the electric vehicle industry, where Canada-U.S. collaboration could accelerate progress.

At Monday's announcement, Economy Minister Pierre Fitzgibbon spoke at length about the province's deposits of lithium and nickel — key components in electric vehicle batteries — as well as its supply of low-emission hydroelectricity.

"If we play our cards right, we could become world leaders in this market of the future," Fitzgibbon said.

Currently, many of those strategic minerals found in Quebec are exported to Asia where they are turned into battery cells, and then imported back to Quebec by companies like Lion, said Mickaël Dollé, a chemistry professor at the Université de Montréal.

By opening a battery assembly plant in Quebec, Lion could help stimulate more cell-makers, such as the Northvolt project near Montreal, to set up shop in the province. Further localizing the supply chain, Dollé said, means better value and a greener product. 

But other countries have the same goal in mind, he said, and the window for the province to establish itself as an important player in the emerging electric vehicle battery industry is closing quickly, as major Ford Oakville deal commitments accelerate competition.

"The decision has to be taken now, or in the coming months, but if we wait too long we may miss our main goal which is to get our own supply chain in Canada," Dollé said.

What's in a name?
Monday's announcement was closely watched in Quebec for what it foretold about the political future as well as the economic one.

By coming to Montreal and touring a vaccination clinic before making the funding announcement, Trudeau fed speculation in the province that he is preparing to call an election soon.

Intrigue also surrounded the informal meeting Trudeau had with Legault on Monday. The Quebec premier and members of his government have repeatedly expressed frustration with Trudeau during the pandemic.
