Floating Solar at Fort Bragg delivers a 1 MW DoD-backed floatovoltaic array on Big Muddy Lake, boosting renewable energy, resilience, and efficiency via water cooling, with Duke Energy and Ameresco supporting backup power.

 

Key Points

A 1 MW floating PV array on Big Muddy Lake, built by the US Army to boost efficiency, resilience, and backup power.

✅ 1 MW array supplies backup power for training facilities.

✅ Water cooling improves panel efficiency and output.

✅ Partners: Duke Energy, Ameresco; DoD's first floating solar.

 

Floating solar had a moment in the spotlight over the weekend when the US Army unveiled a new solar plant sitting atop the Big Muddy Lake at Fort Bragg in North Carolina. It’s the first floating solar array deployed by the Department of Defense, and it’s part of a growing current of support in the US for “floatovoltaics” and other innovations like space-based solar research.

The army says its goal is to boost clean energy, support goals in the Biden solar plan for decarbonization, reduce greenhouse gas emissions, and give the nearby training facility a source of backup energy during power outages. The panels will be able to generate about one megawatt of electricity, which can typically power about 190 homes, and, when paired with solar batteries, enhance resilience during extended outages.

The installation, the largest in the US Southeast, is a big win for floatovoltaics, and projects like South Korea’s planned floating plant show global momentum for the technology, which has yet to make a big splash in the US. They only make up 2 percent of solar installations annually in the country, according to Duke Energy, which collaborated with Fort Bragg and the renewable energy company Ameresco on the project, even as US solar and storage growth accelerates nationwide.

Upfront costs for floating solar have typically been slightly more expensive than for its land-based counterparts. The panels essentially sit on a sort of raft that’s tethered to the bottom of the body of water. But floatovoltaics come with unique benefits, complementing emerging ocean and river power approaches in water-based energy. Hotter temperatures make it harder for solar panels to produce as much power from the same amount of sunshine. Luckily, sitting atop water has a cooling effect, which allows the panels to generate more electricity than panels on land. That makes floating solar more efficient and makes up for higher installation costs over time.

And while solar in general has already become the cheapest electricity source globally, it’s pretty land-hungry, so complementary options like wave energy are drawing interest worldwide. A solar farm might take up 20 times more land than a fossil fuel power plant to produce a gigawatt of electricity. Solar projects in the US have already run into conflict with some farmers who want to use the same land, for example, and with some conservationists worried about the impact on desert ecosystems.

UK sets new record for wind power generation

Britain Wind Generation Record underscores onshore and offshore wind momentum, as National Grid ESO reported 20.91 GW, boosting zero-carbon electricity, renewables share, and grid stability amid milder weather, falling gas prices, and net zero goals.

 

Key Points

The Britain wind generation record is 20.91 GW, set on 30 Dec, driven by onshore and offshore turbines.

✅ Set on 30 Dec 2022 with peak output of 20.91 GW.

✅ Zero-carbon sources hit 87.2% of grid supply.

✅ Driven by onshore and offshore wind; ESO reported stability.

 

Britain has set a new record for wind generation as power from onshore and offshore turbines helped boost clean energy supplies late last year.

National Grid’s electricity system operator (ESO), which handles Great Britain’s grid operations, said that a new record for wind generation was set on 30 December, when 20.91 gigawatts (GW) were produced by turbines.

This represented the third time Britain’s fleet of wind turbines set new generation records in 2022. In May, National Grid had to ask some turbines in the west of Scotland to shut down, as the network was unable to store such a large amount of electricity when a then record 19.9GW of power was produced – enough to boil 3.5m kettles.

The ESO said a new record was also set for the share of electricity on the grid coming from zero-carbon sources – renewables and nuclear – which supplied 87.2% of total power. These sources have accounted for about 55% to 59% of power over the past couple of years.

The surge in wind generation represents a remarkable reversal in fortunes as a cold snap that enveloped Britain and Europe quickly turned to milder weather.

Power prices had soared as the freezing weather forced Britons to increase their heating use, pushing up demand for energy despite high bills.

The cold weather came with a period of low wind, reducing the production of Britain’s windfarms to close to zero.

Emergency coal-fired power units at Drax in North Yorkshire were put on standby but ultimately not used, while gas-fired generation accounted for nearly 60% of the UK’s power output at times.

However, milder weather in the UK and Europe in recent days has led to a reduction in demand from consumers and a fall in wholesale gas prices. It has also reduced the risk of power cuts this winter, which National Grid had warned could be a possibility.

Wind generation is increasingly leading the power mix in Britain and is seen as a crucial part of Britain’s move towards net zero. The prime minister, Rishi Sunak, is expected to overturn a moratorium on new onshore wind projects with a consultation on the matter due to run until March.

France's new EV incentive rules toughen market for Chinese cars

France EV Incentive Rules prioritize EU-made electric vehicles, tying subsidies to manufacturing emissions and carbon footprint, making Stellantis, Renault, and Tesla Model Y eligible while excluding many China-built models under a new eligibility list.

 

Key Points

Links EV subsidies to manufacturing emissions, favoring EU-made models and restricting many China-built cars.

✅ Subsidies tied to lifecycle manufacturing emissions.

✅ EU production favored; many China-built EVs excluded.

✅ Eligible: Stellantis, Renault, Tesla Model Y; not Model 3.

 

France's revamped new EV rules on consumer cash incentives for electric car purchases favour vehicles made in France and Europe over models manufactured in China, a government list of eligible car types published recently has showed.

Some 65% of electric cars sold in France will be eligible for the scheme, which from Friday will include new criteria covering the amount of carbon emitted in the manufacturing of an electric vehicle (EV).

The list of eligible models includes 24 produced by Franco-Italian group Stellantis (STLAM.MI) and five by French carmaker Renault (RENA.PA). Elon Musk's Tesla (TSLA.O) Model Y will be eligible but not its Model 3.

Electric vehicle brand MG Motors, owned by China's SAIC, said it expects the new rules to weigh on the French EV market, despite the global surge in EV sales seen in recent years.

"There are cars that will entirely lose their competitiveness", an MG spokesperson told Reuters, adding that the brand had decided not to apply for the bonus scheme for its MG4 model because it was "designed to exclude us".

French Finance Minister Bruno Le Maire hailed what he called the new rules' incentive for automakers to reduce their carbon footprint.

"We will no longer be subsidising car production that emits too much CO2," he said in a statement.

President Emmanuel Macron's government has wanted to make French and European-made EVs more affordable for domestic consumers relative to cheaper vehicles produced in China, amid a record EV market share in the country.

The average retail price of an EV in Europe, even as the EU EV share grew during lockdown months, was more than 65,000 euros ($71,000) in the first half of 2023, compared with just over 31,000 euros in China, according to research by Jato Dynamics.

The French government already offered buyers a cash incentive of between 5,000 and 7,000 euros to get more electric cars on the road, at a total cost of 1 billion euros ($1.1 billion) per year.

However, in the absence of cheap European-made EVs, a third of all incentives are going to consumers buying EVs made in China, French finance ministry officials say. The trend has helped spur a surge in imports and a growing competitive gap with domestic producers.

China's auto industry relies heavily on coal-generated electricity, meaning many Chinese-made EVs will henceforth not qualify.

The Ademe agency overseeing the process studied the eligibility of almost 500 EV models and their variants to include in the scheme.

Dacia, the low-cost Renault brand, saw its Spring model imported from China excluded from the list.

Tesla's Model 3 is made in China. The Model Y, which is larger and more expensive, is made mainly in Berlin and was the top selling EV in France over the first 11 months of the year, amid forecasts that EVs could dominate within a decade in many markets.

Canada must commit to 100 per cent clean electricity

Canada Green Investment Gap highlights lagging EV and clean energy funding as peers surge. With a green recovery budget pending, sustainable finance, green bonds, EV charging, hydrogen, and carbon capture are pivotal to decarbonization.

 

Key Points

Canada lags peers in EV and clean energy investment, urging faster budget and policy action to cut emissions.

✅ Per capita climate spend trails US and EU benchmarks

✅ EVs, hydrogen, charging need scaled funding now

✅ Strengthen sustainable finance, green bonds, disclosure

 

Canada is being outpaced on the international stage when it comes to green investments in electric vehicles and green energy solutions, environmental groups say.

The federal government has an opportunity to change course in about three weeks, when the Liberals table their first budget in over two years, the International Institute for Sustainable Development (IISD) argued in a new analysis endorsed by nine other climate action, ecology and conservation organizations.

“Canada’s international peers are ramping up commitments for green recovery, including significant investments from many European countries,” states the analysis, “Investing for Tomorrow, Today,” published March 29.

“To keep up with our global peers, sufficient investments and strengthened regulations, including EV sales regulations, must work in tandem to rapidly decarbonize all sectors of the Canadian economy.”

Deputy Prime Minister and Finance Minister Chrystia Freeland confirmed last week that the federal budget will be tabled April 19. The Liberals are expected to propose between $70 billion and $100 billion in fiscal stimulus to jolt the economy out of its pandemic doldrums.

The government teased a coming economic “green transformation” late last year when Freeland released the fall economic statement, promising to examine federal green bonds, border carbon adjustments and a sustainable finance market, with tweaks like tightening the climate-risk disclosure obligations of corporations.

The government has also proposed a wide range of green measures in its new climate plan released in December — which the think tank called the “most ambitious” in Canada’s history — including energy retrofit programs, boosting hydrogen and other alternative fuels, and rolling out carbon capture technology in a grid where 18% of electricity still came from fossil fuels in 2019.

But the possible “three-year stimulus package to jumpstart our recovery” mentioned in the fall economic statement came with the caveat that the COVID-19 virus would have to be “under control.” While vaccines are being administered, Canada is currently dealing with a rise of highly transmissible variants of the virus.

Freeland spoke with United States Vice-President Kamala Harris on March 25, highlighting potential Canada-U.S. collaboration on EVs alongside the “need to support entrepreneurs, small businesses, young people, low-wage and racialized workers, the care economy, and women” in the context of an economic recovery.

Biden is contemplating a climate recovery plan that could exceed US$2 trillion as Canada looks to capitalize on the U.S. auto pivot to EVs to spur domestic industry. Per capita, that is over 8 times what Canada has announced so far for climate-related spending in the wake of the pandemic, according to a new analysis from green groups.
U.S. President Joe Biden is contemplating a climate and clean energy recovery plan that could “exceed US$2 trillion,” White House officials told reporters this month. “Per capita, that is over eight times what Canada has announced so far for climate-related spending in the wake of the pandemic,” the IISD-led analysis stated.

Biden’s election platform commitment of $508 billion over 10 years in clean energy was also seen as “significantly higher per capita than Canada’s recent commitments.”

Since October 2020, Canada has announced $36 billion in new climate-focused funding, a 2035 EV mandate and other measures, the groups found. By comparison, they noted, a political agreement in Europe proposed that a minimum of 37 per cent of investments in each national recovery plan should support climate action. France and Germany have also committed tens of billions of dollars to support clean hydrogen.

As for electric vehicles (EVs), the United Kingdom has committed $4.9 billion, while Germany has put up $7.5 billion to expand EV adoption and charging infrastructure and sweeten incentive programs for prospective buyers, complementing Canada’s ambitious EV goals announced domestically. The U.K. has also committed $3.5 billion for bike lanes and other active transportation, the groups noted.

Canada announced $400 million over five years this month for a new network of bike lanes, paths, trails and bridges, the first federal fund dedicated to active transportation.

Bimbo Canada signs agreements to offset 100 per cent of its electricity consumption for Canadian operations

Bimbo Canada VPPAs secure renewable electricity from RES wind and solar projects in Alberta, totaling 170MW, via 15-year contracts to offset consumption, advance RE100 goals, and drive decarbonization across bakeries, depots, and distribution centers.

 

Key Points

Virtual power purchase agreements sourcing wind and solar to offset Bimbo Canadas electricity and support RE100.

✅ 15-year RES contracts for Alberta wind and solar capacity

✅ Offsets electricity for bakeries, depots, and distribution centers

✅ Advances Grupo Bimbo RE100 target for 100% renewable power

 

Canada's oldest and largest bakery, Bimbo Canada, has signed two virtual power purchase agreements (VPPAs) with Renewable Energy Systems  (RES) to procure renewable electricity, similar to federal green electricity contracts advancing in Alberta, that will offset 100 per cent of the company's electricity consumption in Canada. The projects are expected to be fully operational by December, 2022.

Canada is the second market, alongside the United States, to enter into VPPAs, where companies like Amazon clean energy projects are expanding rapidly. These agreements, together with additional sustainability initiatives conducted around the world by the parent company Grupo Bimbo, will help the company offset 90 per cent of its global electricity consumption.

"Bimbo Canada is committed to nourishing a better world through productive sustainability practices," said Joe McCarthy, president of Bimbo Canada. "These agreements are the next big step in reducing our environmental footprint, as peers such as Arvato's first solar plant signal industry momentum, and becoming leaders in responsible stewardship of the environment."

The 15-year agreements with RES will support the commercial development of two renewable energy projects in southern Alberta, consisting of wind and solar projects, similar to RBC's solar PPA announced in the region, totaling 170MW of installed capacity. Under these two agreements, Bimbo Canada will procure the benefit of approximately 50MW of renewable electricity to offset electricity consumption for its 16 bakeries, 14 distribution centres and 191 depots. Commercial development for the wind and solar farms will be finalized later this year by RES Canada and the projects are expected to be fully operational by the end of next year.  

"RES is proud that its Alberta wind and solar projects, amid growth such as a $200M Alberta wind farm led by a Buffett-linked firm, are helping Bimbo Canada meet its sustainability initiatives," said Peter Clibbon, RES Senior VP of Development. "It's a win-win situation with our projects delivering competitive wind and solar electricity to Bimbo Canada, and while providing our host communities with long-term tax and landowner income."

In 2018, Grupo Bimbo joined RE100, a global initiative led by The Climate Group and in partnership with Carbon Disclosure Project (CDP) and committed to operating with 100 per cent renewable electricity by 2025. As a leading supplier of fresh-baked goods and snacks for Canadian families, these agreements support the company's targets and builds upon many successful past sustainability initiatives, as market activity by Canadian Solar project sales continues nationwide.

"The renewable electricity initiatives in our operations respond to Grupo Bimbo's deep commitment that we have had for many decades globally with the planet and with present and future generations," said Daniel Servitje, global CEO of Grupo Bimbo. "With this announcement, we have achieved another important milestone for the company on our journey towards becoming 100 per cent renewable electricity by 2025."

Last year, Bimbo Canada reduced product waste and exceeded its product waste reduction target by 18 per cent, which saved four million units of products from landfills. The company also eliminated 174 metric tonnes of plastic per year (equal to 43 adult elephants) through several packaging optimization initiatives.

Earlier this year, Bimbo Canada signed the Canada Plastics Pact (CPP) and, amid a broader push for clean energy exemplified by Edmonton rooftop solar installations, earned its first ENERGY STAR certification for its Hamilton, Ontario bakery. The company will continue to work towards other initiatives that fulfill its commitment to be a sustainable, highly productive and deeply humane company.

Biden's proposed tenfold increase in solar power would remake the U.S. electricity system

US Solar Power 2050 Target projects 45% electricity from solar, advancing decarbonization with clean energy, wind, nuclear, hydropower, hydrogen, and scalable energy storage, while modernizing the grid and transmission to cut emissions and create jobs.

 

Key Points

A goal for solar to supply ~45% of US electricity by 2050, backed by energy storage and other low-carbon generation.

✅ Requires 1,050-1,570 GW solar and matching storage capacity

✅ Utility-scale buildout uses ~10M acres; rooftop 10-20% of capacity

✅ Complemented by wind, nuclear, hydropower, hydrogen, and flexible turbines

 

President Joe Biden has called for major clean energy investments as a way to curb climate change and generate jobs. On Sept. 8, 2021, the White House released a report produced by the U.S. Department of Energy that found that solar power could generate up to 45% of the U.S. electricity supply by 2050, compared to less than 4% today, with about 3% in 2020 noted by industry observers. The Conversation asked Joshua D. Rhodes, an energy technology and policy researcher at the University of Texas at Austin, what it would take to meet this target.

Why such a heavy focus on solar power? Doesn’t a low-carbon future require many types of clean energy, even though wind and solar could meet about 80% of demand according to some research?
The Energy Department’s Solar Futures Study lays out three future pathways for the U.S. grid: business as usual; decarbonization, meaning a massive shift to low-carbon and carbon-free energy sources; and decarbonization with economy-wide electrification of activities that are powered now by fossil fuels.

It concludes that the latter two scenarios would require approximately 1,050-1,570 gigawatts of solar power, which would meet about 44%-45% of expected electricity demand in 2050, even as renewables approach one-fourth of U.S. generation in the near term. For perspective, one gigawatt of generating capacity is equivalent to about 3.1 million solar panels or 364 large-scale wind turbines.

The rest would come mostly from a mix of other low- or zero-carbon sources, including wind, nuclear, hydropower, biopower, geothermal and combustion turbines run on zero-carbon synthetic fuels such as hydrogen. Energy storage capacity – systems such as large installations of high-capacity batteries – would also expand at roughly the same rate as solar, with record growth in solar and storage anticipated by industry in coming years.

One advantage solar power has over many other low-carbon technologies is that most of the U.S. has lots of sunshine. Wind, hydropower and geothermal resources aren’t so evenly distributed: There are large zones where these resources are poor or nonexistent.

Relying more heavily on region-specific technologies would mean developing them extremely densely where they are most abundant. It also would require building more high-voltage transmission lines to move that energy over long distances, which could increase costs and draw opposition from landowners – a key reason the grid isn't yet 100% renewable according to experts – in many regions.

Is generating 45% of U.S. electricity from solar power by 2050 feasible?
I think it would be technically possible but not easy. It would require an accelerated and sustained deployment far larger than what the U.S. has achieved so far, even as the cost of solar panels has fallen dramatically, and wind, solar and batteries are 82% of the utility-scale pipeline across the country. Some regions have attained this rate of growth, albeit from low starting points and usually not for long periods.

The Solar Futures Study estimates that producing 45% of the nation’s electricity from solar power by 2050 would require deploying about 1,600 gigawatts of solar generation. That’s a 1,450% increase from the 103 gigawatts that are installed in the U.S. today, even as wind and solar trend toward 30% of U.S. electricity in some outlooks. For perspective, there are currently about 1,200 gigawatts of electricity generation capacity of all types on the U.S. power grid.

The report assumes that 10%-20% of this new solar capacity would be deployed on homes and businesses. The rest would be large utility-scale deployments, mostly solar panels, plus some large-scale solar thermal systems that use mirrors to reflect the sun to a central tower.

Assuming that utility-scale solar power requires roughly 8 acres per megawatt, this expansion would require approximately 10.2 million to 11.5 million acres. That’s an area roughly as big as Massachusetts and New Jersey combined, although it’s less than 0.5% of total U.S. land mass.

I think goals like these are worth setting, but are good to reevaluate over time to make sure they represent the most prudent path.

California allows electric school buses only from 2035

California Electric School Bus Mandate 2035 sets zero-emission requirements, outlines funding, state reimbursement, fleet electrification, infrastructure, and cost estimates, highlighting exemptions for frontier districts and alignment with clean transportation and climate policy goals.

 

Key Points

California's 2035 policy requires all new school buses be zero-emission, with funding and limited rural exemptions.

✅ Mandates zero-emission purchases for new school buses from 2035

✅ Estimates $5B transition cost with state reimbursement support

✅ Frontier districts may apply for 5-year extensions

 

California Governor Gavin Newsom has signed a new legislation requiring that from 2035, all newly ordered or contracted school buses must be zero-emission, a move aligned with California's push for expanded EV grid capacity statewide.

The state estimates that switching to electric school buses will cost around five billion dollars over the next decade, a projection reflecting electric bus challenges seen globally. That is because a diesel equivalent costs about 200,000 dollars less than a battery-electric version, as highlighted by critical analyses of California policy. And “the California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state.”

There are about 23,800 school buses on the road in California. About 500 are already electric, with conversion initiatives expected to expand the total, and 2,078 electric buses have been ordered.

There are – as always- exceptions to the rule. So-called “frontier districts,” which have less than 600 students or are in a county with a population density of less than ten persons per square mile, can file for a five-year extension, drawing on lessons from large electric bus fleets about route length and charging constraints. However, they must “reasonably demonstrate that a daily planned bus route for transporting pupils to and from school cannot be serviced through available zero-emission technology in 2035.”

Califonia is the fifth US state to mandate electric school buses, and jurisdictions like British Columbia are deploying electric school buses as well. Connecticut, Maryland, Maine, and New York implemented similar legislation, while California continues broader zero-emission freight adoption with Volvo VNR electric trucks entering service across the state.
