Canada, Germany to work together on clean energy

Michigan Distributed Energy Cap Repeal advances a bipartisan bill to boost rooftop solar and net metering, countering DTE and Consumers Energy claims, expanding energy freedom, jobs, and climate resilience across investor-owned utility territories.

Key Points

A Michigan bill to remove the 1% distributed energy cap, expanding rooftop solar, net metering, and clean energy jobs.

✅ Removes 1% distributed generation cap statewide

✅ Supports rooftop solar, net metering, and job growth

✅ Counters utility cost-shift claims with updated tariffs

A bipartisan group of Michigan lawmakers has introduced legislation to eliminate a 1% cap on distributed energy in the state’s investor-owned utility territories.

It’s the third time in recent years that such legislation has been introduced. Though utilities and their political allies have successfully blocked it to date, through tactics some critics say reflect utilities tilting the solar market by incumbents, advocates see an opportunity with a change in state Republican caucus leadership and Michigan’s burgeoning solar industry approaching the cap in some utility territories.

The bill also has support from a broad swath of legislators for reasons having to do with job creation, energy freedom and the environment, amid broader debates over states' push for renewables and affordability. Already the bill has received multiple hearings, even as DTE Energy and Consumers Energy, Michigan’s largest private utilities, are ramping up attacks in an effort to block the bill. 

“It’s going to be vehemently opposed by the utilities but there are only benefits to this if you are anybody but DTE,” said Democratic state Rep. Yousef Rabhi, who cosigned HB 4236 and has helped draft language in previous bills. “If we remove the cap, then we’re putting the public’s interest first, and we’re putting DTE’s interest first if we keep the cap in place.” 

The Michigan Legislature enacted the cap as part of a sweeping 2016 energy bill that clean energy advocates say included a number of provisions that have kneecapped the small-scale distributed energy industry, particularly home solar. The law caps distributed energy production at 1% of a utility’s average in-state peak load for the past five years. 

Republicans have controlled the Legislature and committees since the law was enacted, amid parallel moves such as the Wyoming clean energy bill in another state, and previous attempts to cut the language haven’t received House committee hearings. However, former Republican House leader Lee Chatfield has been replaced, and already the new bill, introduced by Republican state Rep. Gregory Markkanen, the energy committee’s vice chair, has had two hearings. 

Previous attempts to cut the language were also a part of a larger package of bills, and this time around the bill is a standalone. The legislation is also moving as Consumers and Upper Peninsula Power Co. have voluntarily doubled their cap to two percent, which advocates say highlights the need to repeal the cap . 

Rabhi said there’s bipartisan support because many conservatives and progressives view it as an infringement on customers’ energy freedom since the cap will eventually effectively prohibit new distributed energy generation. Legislators say the existing law kills jobs because it severely limits the clean energy industry’s growth, and Rabhi said he’s also strongly motivated by increasing renewable energy production to address climate change. 

In February, Michigan Public Service Commission Chairman Dan Scripps testified to the House committee, with observers also pointing to FERC action on aggregated DERs as relevant context, that the commission is “supportive in taking steps to ensure solar developers in Michigan are able to continue operating and thus support in concept the idea of lifting or eliminating the cap” in order to protect the home solar industry. 

The state’s solar industry has long criticized the cap, and removing it is a “no brainer,” said Dave Strenski, executive director of Solar Ypsi, which promotes rooftop solar in Ypsilanti. 

“If they have a cap and we reach that cap, then rooftop solar is shut down in Michigan,” he said. “The utilities don’t mind solar as long as they own it, and that’s what it boils down to.”  

The state’s utilities see the situation differently. Spokespeople for DTE and Consumers told the Energy News Network that lifting the cap would shift the cost burden of maintaining their territory-wide infrastructure from all customers to low income customers who can’t afford to install solar panels, often invoking reliability examples such as California's reliance on fossil generation to justify caution.

The bill “doesn’t address the subsidy certain customers are paid at the expense of those who cannot afford to put solar panels on their homes,” said Katie Carey, Consumers Energy’s spokesperson. 

However, clean energy advocates argue that studies have found that to be untrue. And even if it were true, Rabhi said, the utilities told lawmakers in 2016 that a new inflow/outflow tariff that the companies successfully pushed for to replace net metering dramatically reduced compensation for home solar users and would address that inequality. 

“DTE’s and Consumers’ own argument is that by making that change, distributed generation is no longer a ‘burden’ on low income customers, so now we have inflow/outflow and the problem should be solved,” Rabhi said. 

He added that claims that DTE and Consumers are looking out for low-income customers are disingenuous because they have repeatedly fought larger allowances for programs that help those customers, and refuse to “dip into their massive corporate profits and make sure poor people don’t have to pay as much for electricity.”

“I don’t want to hear a sob story from DTE about how putting solar panels on the house is going to hurt poor people,” he said. “That is entirely the definition of hypocrisy — that’s the utilities using poor people as a pawn and that’s why people are sick of these corporations.” 

The companies have already begun their public relations attack designed to help thwart the bill. DTE and Consumers spread money generously among Republicans and Democrats in the Legislature each cycle, and the two companies’ dark money nonprofits launched a round of ads targeting Democratic lawmakers, reflecting the broader solar wars playing out nationally. Several sit on the House Energy Committee, which must approve the bill before it can go in front of the full Legislature. 

The DTE-backed Alliance For Michigan Power and Consumers Energy-funded Citizens Energizing Michigan’s Economy have purchased dozens of Facebook ads alluding to action by the legislators, though there hasn’t been a vote. 

Facebook ads aren’t uncommon as they get “bang for their buck,” said Matt Kasper, research director with utility industry watchdog Energy And Policy Institute. Already hundreds of thousands of people have potentially viewed the ads and the groups have only spent thousands of dollars. The ads are likely designed to get Facebook users to interact with the legislators on the issue, Kasper said, even if there’s little information in the ad, and the info in the ad that does exist is highly misleading.

DTE and Consumers spokespersons declined to comment on the spending and directed questions to the dark money nonprofits. No one there could be reached for comment.

Poland Solar PV Boom drives record installations, rooftop and utility-scale growth, EU-aligned incentives, net metering, PPAs, and auctions, pushing capacity toward 8.3 GW by 2024 while prosumers, grid upgrades, and energy management expand.

Key Points

A rapid expansion of Poland's PV market, driven by incentives, PPAs, and prosumers across rooftop and utility-scale.

✅ 2.2 GW added in 2020, triple 2019, led by small-scale prosumers

✅ Incentives: My Current, Clean Air, Agroenergia, net metering

✅ Growth toward 8.3 GW by 2024; PPAs and auctions scale utility

Photovoltaics (PV) is booming in Poland. According to SolarPower Europe, 2.2 gigawatts (GW) of solar power was installed in the country in 2020 - nearly three times as much as the 823 megawatts (MW) installed in 2019. This places Poland fourth across Europe, behind Germany, where a solar power boost has been underway (4.8 GW added in 2020), the Netherlands (2.8 GW) and Spain (2.6 GW). So all eyes in the industry are on the up-and-coming Polish market. The solar industry will come together at Intersolar Europe Restart 2021, taking place from October 6 to 8 at Messe München. As part of The smarter E Europe Restart 2021, manufacturers, suppliers, distributors and service providers will all present their products and innovations at the world's leading exhibition for the solar industry.

All signs point to continued strong growth, with renewables on course to set records across markets. An intermediate, more conservative EU Market Outlook forecast from SolarPower Europe expects the Polish solar market to grow by 35 percent annually, meaning that it will have achieved a PV capacity of 8.3 GW by 2024 as solar reshapes Northern Europe's power prices over the medium term. "PV in Poland is booming at every level - from private and commercial PV rooftop systems to large free-standing installations," says Dr. Stanislaw Pietruszko, President of the Polish Society for Photovoltaics (PV Poland). According to the PV Poland, the number of registered small-scale systems - those under 50 kilowatts (kW) - with an average capacity of 6.5 kilowatts (kW) grew from 155,000 (992 MW) at the end of 2019 to 457,400 (3 GW) by the end of 2020. These small-scale systems account for 75 percent of all PV capacity installed in Poland. Larger PV projects with a capacity of 4 GW have already been approved for grid connection, further attesting to the forecast growth.

8,000 people employed in the PV industry
Andrzej Kazmierski, Deputy Director of the Department for Low-emission Economy within the Polish Ministry of Economic Development, Labour and Technology, explained in the Intersolar Europe webinar "A Rising Star: PV Market Poland" at the end of March 2021 that the PV market volume in Poland currently amounts to 2.2 billion euros, with 8,000 people employed in the industry. According to Kazmierski, the implementation of the Renewable Energy Directive (RED II) in the EU, intended to promote energy communities and collective prosumers as well as long-term power purchase agreements (PPAs), will be a critical challenge, and ongoing Berlin PV barriers debates highlight the importance of regulatory coordination. Renewable energy must be integrated with greater focus into the energy system, and energy management and the grids themselves must be significantly expanded as researchers work to improve solar and wind integration. The government seeks to create a framework for stable market growth as well as to strengthen local value creation.

Government incentive programs in Poland
In addition to drastically reduced PV costs, reinforced by China's rapid PV expansion, and growing environmental consciousness, the Polish PV market is being advanced by an array of government-funded incentive programs such as My Current (230 million euros) and Clean Air as well as thermo-modernization. The incentive program Agroenergia (50 million euros) is specifically geared toward farmers and offers low-interest loans or direct subsidies for the construction of solar installations with capacities between 50 kW and 1 MW. Incentive programs for net metering have been extended to small and medium enterprises to provide stronger support for prosumers. Solar installations producing less than 50 kW benefit from a lower value-added tax of just eight percent (compared to the typical 23 percent). The acquisition and installation costs can be offset against income, in turn reducing income tax.
Government-funded auctions are also used to finance large-scale facilities, where the government selects operators of systems running on renewable energy who offer the lowest electricity price and funds the construction of their facilities. The winner of an auction back in December was an investment project for the construction of a 200 MW solar park in the Pomeranian Voivodeship.

Companies turn to solar power for self-consumption
Furthermore, Poland is now playing host to larger solar projects that do not rely on subsidies, as Europe's demand lifts US equipment makers amid supply shifts, such as a 64 MW solar farm in Witnica being built on the border to Germany whose electricity will be sold to a cement factory via a multi-year power purchase agreement. A new factory in Konin (Wielkopolska Voivodeship) for battery cathode materials to be used in electric cars will be powered with 100-percent renewable electricity. Plus, large companies are increasingly turning to solar power for self-consumption. For example, a leading manufacturer of metal furniture in Suwalki (Podlaskie Voivodeship) in northeastern Poland has recently started meeting its demand using a 2 MW roof-mounted and free-standing installation on the company premises.

Canada Renewable Energy Partnerships advance wind power and clean electricity in Alberta and Saskatchewan, cutting emissions and supporting net-zero goals through Capital Power and SaskPower agreements with Indigenous participation and 25-year supply contracts.

Key Points

Government-backed deals with Capital Power and SaskPower to deliver clean electricity and reduce emissions.

✅ 25-year renewable supply for federal facilities

✅ New Halkirk 2 Wind project in Alberta

✅ Emissions cuts with Indigenous participation

The Government of Canada has partnered with two major energy providers in Western Canada (Prairie provinces) on renewable energy projects.

Tourism Minister Randy Boissonnault appeared in Edmonton on Friday to announce a new Alberta wind-generation facility in partnership with Capital Power.

It's one of two new energy partnerships in Western Canada as part of the 2030 emissions reduction plan by Public Services and Procurement Canada.

On Jan. 1, the federal government awarded a contract worth up to $500 million to Capital Power to provide all federal facilities in Alberta with renewable electricity as part of Alberta's renewable energy surge for 25 years.

"We're proud to partner with the government of Canada to help them reach their 100 per cent clean electricity by 2025 goal," said Jason Comandante, Capital Power vice president of commercial services.

The agreement also includes opportunities for Indigenous participation, including facility development partnerships and employment and training opportunities.

"At Capital Power, we are committed to net-zero by 2045, and are proud to take action against climate change. Collaborative agreements like this help support our net-zero goals, provide us opportunities to meaningfully engage Indigenous communities, and help decarbonize Alberta's power grid," Comandante said.

Capital Power will provide around 250,000 megawatt-hours of electricity each year through existing renewable energy credits while the new Capital Power Halkirk 2 Wind facility is being developed.

Located near Paintearth, Alta., the proposed wind farm will have up to 35 turbines and generate enough power for the average yearly electricity needs of more than 70,000 Alberta homes.

The project is currently awaiting regulatory approval, within Alberta's energy landscape, with construction projected to begin this summer. When complete, it will supply 49 per cent of its output to the federal government.

"Through the agreement, the federal government is supporting the ongoing development of renewable energy infrastructure development within the province," Boissonnault said.

The new partnership will join another in Saskatchewan and complement Alberta solar facilities that have been contracted at lower cost than natural gas.

In 2022, the federal government signed an agreement with SaskPower to supply clean electricity to the approximately 600 federal facilities in Saskatchewan. That wind project is expected to come online by 2024.

Boissonnault said the two initiatives combined will reduce carbon dioxide emissions in Alberta and Saskatchewan by about 166 kilotonnes.

"That is the equivalent of the emissions from more than 50,000 cars driven for one year. So, if you think about that, that's a great reduction right here in Alberta and Saskatchewan," he said.

"These are concrete steps to ensuring that Canada remains a leader of renewable energy on the global stage and grid modernization projects to help the fight against climate change."

U.S. EV Manufacturing Expansion accelerates decarbonization as Ford and SK Innovation invest in lithium-ion batteries and truck assembly in Tennessee and Kentucky, building new factories, jobs, and supply chain infrastructure in right-to-work states.

Key Points

A rapid scale-up of U.S. electric vehicle production, battery plants, and assembly lines fueled by major investments.

✅ Ford and SK build battery and truck plants by 2025

✅ $11.4B investment, 11,000 jobs in TN and KY

✅ Right-to-work context reshapes union dynamics

One theme of this newsletter is that the world’s physical infrastructure will have to massively change if we want to decarbonize the economy by 2050, which the United Nations has said is necessary to avoid the worst effects of the climate crisis. This won’t be as simple as passing a carbon tax or a clean-electricity mandate: Wires will have to be strung as the power grid expands; solar farms will have to be erected; industries will have to be remade. And although that kind of change can be orchestrated only by the government (hence the importance of the infrastructure bills in Congress), consumers and companies will ultimately do most of the work to make it happen.

Take electric cars, for instance. An electric car is an expensive, highly specialized piece of technology, but building one takes even more expensive, specialized technology—tools that tend to be custom-made, large and heavy, and spread across a factory or the world. And if you want those tools to produce a car in a few years, you have to start planning now, as the EV timeline accelerates ahead.

That’s exactly what Ford is doing: Last night, the automaker and SK Innovation, a South Korean battery manufacturer, announced that they were spending $11.4 billion to build two new multi-factory centers in Tennessee and Kentucky that are scheduled to begin production in 2025. The facilities, which will hire a combined 11,000 employees, will manufacture EV batteries and assemble electric F-series pickup trucks. While Ford already has several factories in Kentucky, this will be its first plant in Tennessee in six decades. The 3,600-acre Tennessee facility, located an hour outside Memphis, will be Ford’s largest campus ever—and its first new American vehicle-assembly plant in decades.

The politics of this announcement are worth dwelling on. Ford and SK Innovation were lured to Tennessee with $500 million in incentives; Kentucky gave them $300 million and more than 1,500 acres of free land. Ford’s workers in Detroit have historically been unionized—and, indeed, a source of power in the national labor movement. But with these new factories, Ford is edging into a more anti-union environment: Both Tennessee and Kentucky are right-to-work states, meaning that local laws prevent unions from requiring that only unionized employees work in a certain facility. In an interview, Jim Farley, Ford’s CEO, played coy about whether either factory will be unionized. (Last week, the company announced that it was investing $250 million, a comparative pittance, to expand EV production at its unionized Michigan facilities.)

That news might depress those on the left who hope that old-school unions, such as the United Auto Workers, can enjoy the benefits of electrification. But you can see the outline of a potential political bargain here. Climate-concerned Democrats get to see EV production expand in the U.S., creating opportunities for Canada to capitalize as supply chains shift, while climate-wary Republicans get to add jobs in their home states. (And unions get shafted.) Whether that bargain can successfully grow support for more federal climate policy, further accelerating the financial-political-technological feedback loop that I’ve dubbed “the green vortex,” remains to be seen.

Read: How the U.S. made progress on climate change without ever passing a bill

More important than the announcement is what it portends. In the past, environmentalists have complained that even when the law has required that automakers make climate-friendly cars, they haven’t treated them as a major product. It’s easy to tune out climate-friendly announcements as so much corporate greenwashing, amid recurring EV hype, but Ford’s two new factories represent real money: The automaker’s share of the investment exceeds its 2019 annual earnings. This investment is sufficiently large that Ford will treat EVs as a serious business line.

And if you look around globally, you’ll see that Ford isn’t alone. EVs are no longer the neglected stepchild of the global car industry. Here are some recent headlines:

Nine percent of new cars sold globally this year will be EVs or plug-in hybrids, according to S&P Global. That’s up from 3 percent two years ago, a staggering, iPhone-like rise.

GM, Ford, Volkswagen, Toyota, BMW, and the parent company of Fiat-Chrysler have all pledged that by 2030, at least 40 percent of their new cars worldwide will run on a non-gasoline source, and there is scope for Canada-U.S. collaboration as companies turn to electric cars. A few years ago, the standard forecast was that half of new cars sold in the U.S. would be electric by 2050. That timeline has moved up significantly not only in America, but around the world. (In fact, counter to its high-tech self-image, America is the laggard in this global transition. The two largest markets for EVs worldwide are China and the European Union.)

More remarkably (and importantly), automakers are spending like they actually believe that goal: The auto industry as a whole will pump more than $500 billion into EV investment by 2030, and new assembly deals are putting Canada in the race. Ford’s investment in these two plants represents less than a third of its planned total $30 billion investment in EV production by 2025, and that’s relatively small compared with its peers’. Volkswagen has announced more than $60 billion in investment. Honda has committed $46 billion.

Norway could phase out gas cars ahead of schedule. The country has one of the world’s most robust pro-EV policies, and it is still outperforming its own mandates. In the most recent accounting period, eight out of 10 cars had some sort of electric drivetrain. If the current trend holds, Norway would sell its last gas car in April of next year—and while I doubt the demise will be that steep, consumer preferences are running well ahead of its schedule to ban new gas-car sales by 2025.

Electric Fleet Grid Planning aligns utilities, charging infrastructure, distribution upgrades, and substation capacity to meet megawatt loads from medium- and heavy-duty EV trucks and buses, enabling managed charging, storage, and corridor fast charging.

Key Points

A utility plan to upgrade feeders and substations for EV fleets, coordinating charging, storage, and load management.

✅ Plans distribution, substation, and transformer upgrades

✅ Supports managed charging and on-site storage

✅ Aligns utility investment with fleet adoption timelines

As more electric buses and trucks enter the market, future fleets will require a lot of electricity for charging and will challenge state power grids over time. While some utilities in California and elsewhere are planning for an increase in power demand, many have yet to do so and need to get started.

This issue is critical, because freight trucks emit more than one-quarter of all vehicle emissions. Recent product developments offer growing opportunities to electrify trucks and buses and slash their emissions (see our recent white paper). And just last week, a group of 15 states plus D.C. announced plans to fully electrify truck sales by 2050. Utilities will need to be ready to power electric fleets.

Electric truck fleets need substantial power
Power for trucks and buses is generally more of an issue than for cars because trucks typically have larger batteries and because trucks and buses are often parts of fleets with many vehicles that charge at the same location. For example, a Tesla Model 3 battery stores 54-75 kWh; a Proterra transit bus battery stores 220-660 kWh. In Amsterdam, a 100-bus transit fleet is powered by a set of slow and fast chargers that together have a peak load of 13 MW (megawatts). This is equivalent to the power used by a typical large factory. And they are thinking of expanding the fleet to 250 buses.

California utilities are finding that grid capacity is often adequate in the short term, but that upgrade needs likely will grow in the medium term.
Many other fleets also will need a lot of "juice." For example, a rough estimate of the power needed to serve a fleet of 200 delivery vans at an Amazon fulfillment center is about 4 MW. And for electric 18-wheelers, chargers may need up to 2 MW of power each; a recent proposal calls for charging stations every 100 miles along the U.S. West Coast’s I-5 corridor, highlighting concerns about EVs and the grid as each site targets a peak load of 23.5 MW.

Utilities need distribution planning
These examples show the need for more power at a given site than most utilities can provide without planning and investment. Meeting these needs often will require changes to primary and secondary power distribution systems (feeders that deliver power to distribution transformers and to end customers) and substation upgrades. For large loads, a new substation may be needed. A paper recently released by the California Electric Transportation Coalition estimates that for loads over 5 MW, distribution system and substation upgrades will be needed most of the time. According to the paper, typical utility costs are $1 million to $9 million for substation upgrades, $150,000 to $6 million for primary distribution upgrades, and $5,000 to $100,000 for secondary distribution upgrades. Similarly, Black and Veatch, in a paper on Electric Fleets, also provides some general guidance, shown in the table below, while recognizing that each site is unique.

California policy pushes utilities toward planning
In California, state agencies and a statewide effort called CALSTART have been funding demonstration projects and vehicle and charger purchases for several years to support grid stability as electrification ramps up. The California Air Resources Board voted in June to phase in zero-emission requirements for truck sales, mandating that, beginning in 2024, manufacturers must increase their zero-emission truck sales to 30-50 percent by 2030 and 40-75 percent by 2035. By 2035, more than 300,000 trucks will be zero-emission vehicles.

California utilities operate programs that work with fleet owners to install the necessary infrastructure for electric vehicle fleets. For example, Southern California Edison operates the Charge Ready Transport program for medium- and heavy-duty fleets. Normally, when customers request new or upgraded service from the utility, there are fees associated with the new upgrade. With Charge Ready, the utility generally pays these costs, and it will sometimes pay half the cost of chargers; the customer is responsible for the other half and for charger installation costs. Sites with at least two electric vehicles are eligible, but program managers report that at least five vehicles are often needed for the economics to make sense for the utility.

One way to do this is to develop and implement a phased plan, with some components sized for future planned growth and other components added as needed. Southern California Edison, for example, has 24 commitments so far, and has a five-year goal of 870 sites, with an average of 10 chargers per site. The utility notes that one charger usually can serve several vehicles and that cycling of charging, some storage, and other load management techniques through better grid coordination can reduce capacity needs (a nominal 10 MW load often can be reduced below 5 MW).

Through this program, utility representatives are regularly talking with fleet operators, and they can use these discussions to help identify needed upgrades to the utility grid. For example, California transit agencies are doing the planning to meet a California Air Resources Board mandate for 100 percent electric or fuel cell buses by 2040; utilities are talking with the agencies and their consultants as part of this process. California utilities are finding that grid capacity is often adequate in the short term, but that upgrade needs likely will grow in the medium term (seven to 10 years out). They can manage grid needs with good planning (school buses generally can be charged overnight and don’t need fast chargers), load management techniques and some energy storage to address peak needs.

Customer conversations drive planning elsewhere
We also spoke with a northeastern utility (wishing to be unnamed) that has been talking with customers about many issues, including fleets. It has used these discussions to identify a few areas where grid upgrades might be needed if fleets electrify. It is factoring these findings into a broader grid-planning effort underway that is driven by multiple needs, including fleets. Even within an integrated planning effort, this utility is struggling with the question of when to take action to prepare the electric system for fleet electrification: Should it act on state or federal policy? Should it act when the specific customer request is submitted, or is there something in between? Recognizing that any option has scheduling and cost allocation implications, it notes that there are no easy answers.

Many utilities need to start paying attention
As part of our research, we also talked with several other utilities and found that they have not yet looked at how fleets might relate to grid planning. However, several of these companies are developing plans to look into these issues in the next year. We also talked with a major truck manufacturer, also wishing to remain unnamed, that views grid limitations as a key obstacle to truck electrification. 

Based on these cases, it appears that fleet electrification can have a substantial impact on electric grids and that, while these impacts are small at present, they likely will grow over time. Fleet owners, electric utilities, and utility regulators need to start planning for these impacts now, so that grid improvements can be made steadily as electric fleets grow. Fleet and grid planning should happen in parallel, so that grid upgrades do not happen sooner or later than needed but are in place when needed, including the move toward a much bigger grid as EV adoption accelerates. These grid impacts can be managed and planned for, but the time to begin this planning is now.

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.”
