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.

Fact check: Claim on electric car charging efficiency gets some math wrong

EV Charging Coal and Oil Claim: Fact-check of kWh, CO2 emissions, and electricity grid mix shows 70 lb coal or ~8 gallons oil per 66 kWh, with renewables and natural gas reducing lifecycle emissions.

 

Key Points

A viral claim on EV charging overstates oil use; accurate figures depend on grid mix: ~70 lb coal or ~8 gallons oil.

✅ About 70 lb coal or ~8 gal oil per 66 kWh, incl. conversion losses

✅ EVs average ~100 g CO2 per mile vs ~280 g for 30 mpg cars

✅ Grid mix includes renewables, nuclear, natural gas; oil use is low

 

The claim: Average electric car requires equivalent of 85 pounds of coal or six barrels of oil for a single charge

The Biden administration has pledged to work towards decarbonizing the U.S. electricity grid by 2035. And the recently passed $1.2 trillion infrastructure bill provides funding for more electric vehicle (EV) charging infrastructure, including EV charging networks across the country under current plans.

However, a claim that electric cars require an inordinate amount of oil or coal energy to charge has appeared on social media, even as U.S. plug-ins traveled 19 billion miles on electricity in 2021.

“An average electric car takes 66 KWH To charge. It takes 85 pounds of coal or six barrels of oil to make 66 KWH,” read a Dec 1 Facebook post that was shared nearly 500 times in a week. “Makes absolutely no sense.” 

The post included a stock image of an electric car charging, though actual charging costs depend on local rates and vehicle efficiency.

This claim is in the ballpark for the coal comparison, but the math on the oil usage is wildly inaccurate.

It would take roughly 70 pounds of coal to produce the energy required to charge a 66 kWh electric car battery, said Ian Miller, a research associate at the MIT Energy Initiative. That's about 15 pounds less than is claimed in the post.

The oil number is much farther off.

While the post claims that it takes six barrels of oil to charge a 66 kWh battery, Miller said the amount is closer to 8 gallons  — the equivalent of 20% of one barrel of oil.

He said both of his estimates account for energy lost when fossil fuels are converted into electricity. 

"I think the most important question is, 'How do EVs and gas cars compare on emissions per distance?'," said Miller. "In the US, using average electricity, EVs produce roughly 100 grams of CO2 per mile."

He said this is more than 60% less than a typical gasoline-powered car that gets 30 mpg, aligning with analyses that EVs are greener in all 50 states today according to recent studies. Such a vehicle produces roughly 280 grams of CO2 per mile.

Lifecycle analyses also show that the CO2 from making an EV battery is not equivalent to driving a gasoline car for years, which often counters common misconceptions.

"If you switch to an electric vehicle, even if you're using fossil fuels (to charge), it's just simply not true that you'll be using more fossil fuel," said Jessika Trancik, a professor at the Massachusetts Institute of Technology who studies the environmental impact of energy systems.  

However, she emphasized electric cars in the U.S. are not typically charged using only energy from coal or oil, and that electricity grids can handle EVs with proper management.

The U.S. electricity grid relies on a diversity of energy sources, of which oil and coal together make up about 20 percent, according to a DOE spokesperson. This amount is likely to continue to drop as renewable energy proliferates in the U.S., even as some warn that state power grids will be challenged by rapid EV adoption. 

"Switching to an electric vehicle means that you can use other sources, including less carbon-intensive natural gas, and even less carbon-intensive electricity sources like nuclear, solar and wind energy, which also carry with them health benefits in the form of reduced air pollutant emissions," said Trancik. 

Our rating: Partly false
Based on our research, we rate PARTLY FALSE the claim that the average electric car requires the equivalent of 85 pounds of coal or six barrels of oil for a single charge. The claim is in the ballpark on coal consumption, as an MIT researcher estimates that around 70 pounds. But the oil usage is only about 8 gallons, which is 20% of one barrel. And the actual sources of energy for an electric car vary depending on the energy mix in the local electric grid.

Canada is a solar power laggard, this expert says

Canada Distributed Energy faces disruption as solar, smart grids, microgrids, and storage scale utility-scale renewables, challenging centralized utilities and accelerating decarbonization, grid modernization, and distributed generation across provinces like Alberta.

 

Key Points

Canada Distributed Energy shifts from centralized grids to local solar, wind, and storage for reliable low-carbon power.

✅ Morgan Solar and Enbridge launch Alberta Solar One, 13.7 MW.

✅ Optical films boost panel efficiency, lowering cost per watt.

✅ Strong utilities slow adoption of microgrids and smart grids.

 

By Nick Waddell

Disruption is coming to electricity generation but Canada has become a laggard when it comes to not just adoption of alternative energy sources but in moving to a more distributed model of electricity generation. That’s according to Mike Andrade, CEO of Morgan Solar, whose new solar project in conjunction with Enbridge has just come online in Alberta, a province known as a powerhouse for both green and fossil energy in Canada.

“There’s a lot of inertia to Canada’s electrical system and I don’t think that bodes well,” said Andrade, who spoke on BNN Bloomberg on Thursday. 

“Canada is one of the poorest places for uptake of solar, as NEB data on solar demand indicates,” Andrade said, “I believe a lot of it has to do with the fact that we have strong provincial utilities that have their mandates and their chosen technologies.”

Alberta Solar One, a 13.7 MW power facility near Lethbridge, Alberta, had its unveiling this week amid red-hot solar growth in Alberta that shows no sign of slowing. It’s a 36,500-panel farm constructed by Enbridge in a quick six-month turnaround as part of the power company’s pledge to become a carbon-free generator by 2050. Along with solar, Enbridge has made big investments in offshore and onshore wind farms in the United States, while also producing so-called green hydrogen at an Ontario plant.

Private company Morgan Solar considers the Alberta Solar One project as the first utility-scale validation of its technology, which uses optical films to redirect light onto photovoltaic cells to further power production. 

“We use an advanced modelling system and a variety of tools to design very simple optical systems that can be easily inserted into a panel,” Andrade said. “They cost less and bring down the cost per watt. It captures light that would otherwise miss the cells and so you get more power per cell area than any other commercial technology at this point.”

Like renewables in general, solar energy has been thrust into the spotlight as governments worldwide aim to make good on their climate change and emissions pledges, with analyses showing zero-emissions electricity by 2035 is possible in Canada, and convert power generation from fossil fuels to alternative sources. 

The market has paid attention, too, driving up values on renewable energy stocks across the board, including solar stocks, as provinces like Alberta explore selling renewable energy into broader markets. Last year, the Invesco Solar ETF, which tracks the MAC Global Solar Energy Index, soared 234 per cent, while Canadian companies with solar assets like Algonquin Power and Northland Power have been winners over the past few years.

Canadian cleantech companies involved in the solar power sector have also fared well, with names like UGE International (UGE International Stock Quote, Chart, News, Analyst. Financials TSXV:UGE), Aurora Solar and 5N Plus (5N Plus Stock Quote, Chart, News, Analysts, Financials TSX:VNP) having attracted investor attention of late.

Currently, part of the push in alternative energy involves the move from centralized to a more distributed picture of power generation, where solar panels, wind turbines and small modular nuclear reactors can operate close to or within sources of consumption like cities.

But Andrade says Canada has a lot of catching up to do on that front, especially as its current system seems devoted to maintaining the precedence of large, centralized power production — along with the utility companies that generate it.

“Canada is going to be left with this big, old fashioned hub and spoke model, and that’s increasingly going to be out-competed by a distributed grid, call them smart grids or micro grids,” Andrade said.

“That’s the future that solar is going to drive along with storage, and I personally don’t think Canada is prepared for it, not because we can’t do it but because regulatory and incumbency is holding us back from doing that,” he said.

“We pay our utilities, saying, ‘You invest capital and we’ll give you a fixed return on capital.’ Well, guess what? You’re going to get large, centralized capital projects which are going to get big central generation hub and spoke distribution,” Andrade said.

Ahead of the Canadian federal government’s tabling next week of its first budget in two years, many in the energy sector will be taking notes on the Liberal government’s investments in the so-called green recovery after the economic downturn, with renewable energy proponents hoping for further support, noting Alberta’s renewable energy surge could power thousands of jobs, to shift Canada’s resource sector away from fossil fuels.

By comparison, President Biden in the US recently unveiled his $2-billion infrastructure plan which put precedence on greening the country’s power grid, encouraging the adoption of electric vehicles and supporting renewable resource development, and Canadian studies suggest 2035 zero-emission power is practical and profitable as well across the national grid. 

On disruption in power generation, Andrade said there are parallels to be drawn from information technology, which has historically made a point of discarded outdated models along the way.

“I was at IBM, and they had the mainframe business and that got blown up. I also worked with Nortel and Celestica and they got blown up —and it wasn’t due to having better central hub and spoke systems. They got beat up by this distributed system,” Andrade said. 

“The same thing is going to happen here and the disruption is coming in electricity generation as well,” he said.

Can food waste be turned into green hydrogen to produce electricity?

Food Waste to Green Hydrogen uses biological production to create clean energy, enabling waste-to-energy, decarbonization, and renewable hydrogen for electricity, industrial processes, and transport fuels, developed at Purdue University Northwest with Purdue Research Foundation licensing.

 

Key Points

A biological process converting food waste into renewable hydrogen for clean energy, electricity, industry, and transport.

✅ Enables rapid, scalable waste-to-hydrogen deployment

✅ Supports grid power, industrial heat, and mobility fuels

✅ Backed by patents, DOE grants, and licensing deals

 

West Lafayette, Indiana-based Purdue Research Foundation recently completed a licensing agreement with an international energy company – the name of which was not disclosed – for the commercialization of a new process discovered at Purdue University Northwest (PNW) for the biological production of green hydrogen from food waste. A second licensing agreement with a company in Indiana is under negotiation.


Food waste into green hydrogen
Researchers say that this new process, which uses food waste to biologically produce hydrogen, can be used as a clean energy source for producing electricity, as well as for chemical and industrial processes like green steel production or as a transportation fuel.

Robert Kramer, professor of physics at PNW and principal investigator for the research, says that more than 30% of all food, amounting to $48 billion, is wasted in the United States each year. That waste could be used to create hydrogen, a sustainable energy source alongside municipal solid waste power options. When hydrogen is combusted, the only byproduct is water vapor.

The developed process has a high production rate and can be implemented quickly to support large H2 energy systems in practice. The process is robust, reliable, and economically viable for local energy production and processes.

The research team has received five grants from the US Department of Energy and the Purdue Research Foundation totaling around $800,000 over the last eight years to develop the science and technology that led to this process, much like advances in advanced nuclear reactors drive clean energy innovation.

Two patents have been issued, and a third patent is currently in the final stages of approval. Over the next nine months, a scale-up test will be conducted, reflecting how power-to-gas storage can integrate with existing infrastructure. Based upon test results, it is anticipated that construction could start on the first commercial prototype within a year.

Last week, a facility designed to turn non-recyclable plastics into green hydrogen was approved in the UK, as other innovations like the seawater power concept progress globally. It is the second facility of its kind there.

Cost is the main reason stopping Canadians from buying an electric car: Survey

Canada EV Incentives drive adoption toward the 2035 zero-emission target, with rebates, federal and provincial programs boosting affordability amid concerns over charging infrastructure, range anxiety, and battery life, according to a BNN Bloomberg-Leger survey.

 

Key Points

Canada EV incentives are rebates and tax credits reducing EV costs to accelerate zero-emission vehicle adoption nationwide.

✅ Federal and provincial rebates reduce EV purchase prices

✅ Incentives offset range, battery, and charging concerns

✅ Larger incentives correlate with higher adoption rates

 

If the federal government wants to meet its ambitious EV goals of having all cars and passenger trucks sold in Canada be zero emissions by 2035, it’s going to have to do something about the cost of these vehicles.

A new survey from BNN Bloomberg and RATESDOTCA has found that cost is the number one reason stopping Canadians from buying an electric car.

The survey, which was conducted by Leger Marketing earlier this month, asked 1,511 Canadians if they were planning to purchase a new electric vehicle in the near future. It found that just over one in four, or 26 per cent of Canadians, are planning to do so, with Atlantic Canada lagging other regions. On the other hand, 19 per cent of Canadians are planning to buy a gas/diesel/hybrid card for their next purchase. 

Those who aren’t planning on buying an EV were asked what the biggest reason for their decision was. By far, it was the price of these vehicles: 31 per cent of this group cited cost as the main reason for not electrifying their ride. Another 59 per cent of respondents cited it as a concern, but not the main one. Other reasons for not wanting to buy an electric vehicle included lack of infrastructure (18 per cent), range concerns (16 per cent), and battery life and replacement (13 per cent), and some report EV shortages and wait times too.

What’s interesting is that it’s clear that government incentives for EVs are the most powerful tool right now to drive adoption, though some argue subsidies are a bad idea for Canada. When asked if further government incentives would convince them to buy an electric vehicle, 78 per cent of those surveyed said yes.

That’s right. If more governments increased the incentives offered for buying electric vehicles, reaching the goal of only selling zero emission vehicles in Canada by 2035 would no longer be a pipe dream, despite 2035 mandate skepticism from some.

At the moment, only Quebec and B.C. offer government incentives to buy an electric vehicle, even as B.C. charging bottlenecks are predicted. The federal government offers up to a $5,000 incentive, with restrictions including a limit on the total price of the vehicle, and has signaled EV sales regulations are forthcoming. Ontario previously offered a rebate of up to $14,000, however, the popular program was cancelled when the Progress Conservative government was elected in 2018.

The cancellation led to a plunge in new electric vehicle sales in Ontario, falling more than 55 per cent in the first six months of 2019 when compared to the same time period in the previous year, according to Electric Mobility Canada.

It’s no surprise that the larger the incentive, the more Canadians will be swayed to buy an electric car. Perhaps what’s surprising is that the incentive doesn’t even have to be as large as the previous Ontario rebate was. The survey found that seven per cent of Canadians would buy an electric vehicle if they got an incentive ranging anywhere from $5,001-$7,250. A full 35 per cent said a $12,500 or higher incentive would convince them.

The majority of Canadians surveyed said they use their vehicles for leisure or commuting to work. Leisure uses include running errands and seeing friends and family, of which 43 per cent of respondents said was the primary way they used their vehicle. Meanwhile, 36 per cent said they primarily used their car to commute to work.

The survey also found that incentives were more effective at convincing younger people to buy an electric vehicle. Eighty-three per cent of those under the age of 55 could be swayed by new incentives. But for those over 55, only 66 per cent said they would change their mind.

✅ 6-week Center of Excellence training for all recruits

✅ Second 107-meter blade mold boosts capacity

 

GE Renewable Energy plans to recruit 300 employees in 2021 at its LM Wind Power wind turbine blade factory in Cherbourg, France / Opened almost three years ago in April 2018, the factory today counts more than 450 employees / Every new hire will go through an intensive training program at the factory's ‘Center of Excellence' to learn wind turbine blade manufacturing processes / Site has produced the first offshore wind turbine blade longer than 100 meters, 107-meters long / Second 107-meter blade manufacturing mold is being installed at the plant today

GE Renewable Energy announced today its plan to recruit 300 employees at its LM Wind Power wind turbine blade manufacturing site in Cherbourg, France, in 2021. Every new hire will go through an intensive training program at the factory's ‘Center of Excellence' to learn wind turbine blade manufacturing processes supporting offshore wind energy growth in Europe. The expanded production workforce will allow LM Wind Power to meet the growing industry demand for offshore wind equipment, including emerging offshore green hydrogen applications across the sector.

The factory currently has more than 450 employees, with 34 percent being women. The facility became the first wind turbine blade manufacturing site in France when it was opened almost three years ago in April 2018, while Spanish wind factories faced temporary closures due to COVID-19 restrictions.

The facility has produced the first offshore wind turbine blade longer than 100 meters, a 107-meters long blade that will be used in GE’s Haliade-X offshore wind turbine. A second 107-meter blade manufacturing mold is currently being installed at the plant to support growing project pipelines like those planned off Massachusetts' South Coast in the U.S.

Florence Martinez Flores, the site’s Human Resources Director, said: "The arrival of the second mold within the factory marks an increased activity for LM Wind Power in Cherbourg, and we are happy to welcome a large wave of new employees, allowing us to participate in social development and create more jobs in the surrounding community, but also to bring new skills to the region."

Recent investments such as EDF Irish offshore wind stake news underscore the broader market momentum.

The Cherbourg team is mostly looking to expand its production workforce, with positions that are open to all profiles and backgrounds. Every new employee will be trained to manufacture wind turbine blades through LM Wind Power's ‘Center of Excellence' training program – a six-week theoretical and practical training course, which will develop the skills and technical expertise required to produce high-quality wind turbine blades and support wind turbine operations and maintenance across the industry. The site will also be looking for production supervisors, quality controllers and maintenance technicians.

Ontario to Reintroduce Renewable Energy Projects 5 Years After Cancellations

Ontario Renewable Energy Procurement 2024 will see the IESO secure wind, solar, and hydro power to meet rising electricity demand, support transit electrification, bolster grid reliability, and serve manufacturing growth across the province.

 

Key Points

A provincial IESO initiative to add 2,000 MW of clean power and plan 3,000 MW more to meet rising demand.

✅ IESO to procure 2,000 MW from wind, solar, hydro

✅ Exploring 3,000 MW via upgrades and expansions

✅ Demand growth ~2% yearly; electrification and industry

 

After the Ford government terminated renewable energy contracts five years ago, despite warnings about wind project cancellation costs that year, Ontario's electricity operator, the Independent Electricity System Operator (IESO), is now planning to once again incorporate wind and solar initiatives to address the province's increasing power demands.

The IESO, responsible for managing the provincial power supply, is set to secure 2,000 megawatts of electricity from clean sources, which include wind, solar, and hydro power, as wind power competitiveness increases across Canada. Additionally, the IESO is exploring the possibilities of reacquiring, upgrading, or expanding existing facilities to generate an additional 3,000 MW of electricity in the future.

These new power procurement efforts in Ontario aim to meet the rising energy demand driven by transit electrification and large-scale manufacturing projects, even as national renewable growth projections were scaled back after Ontario scrapped its clean energy program, which are expected to exert greater pressure on the provincial grid.

The IESO projects a consistent growth in demand of approximately two percent per year over the next two decades. This growth has prompted the Ford government, amid debate over Ontario's electricity future in the province, to take proactive measures to prevent potential blackouts or disruptions for both residential and commercial consumers.

This renewed commitment to renewable energy represents a significant policy shift for Premier Doug Ford, reflecting his new stance on wind power over time, who had previously voiced strong opposition to wind turbines and pledged to dismantle all windmills in the province. In 2018, shortly after taking office, the government terminated 750 renewable energy contracts that had been signed by the previous Liberal government, incurring fees of $230 million for taxpayers.

At the time, the government cited reasons such as surplus electricity supply and increased costs for ratepayers as grounds for contract cancellations. Premier Ford expressed pride in the decision, echoing a proud of cancelling contracts stance, claiming that it saved taxpayers $790 million and eliminated what he viewed as detrimental wind turbines that had negatively impacted the province's energy landscape for 15 years.

The Ontario government's new wind and solar energy procurement initiatives are scheduled to commence in 2024, following a court ruling on a Cornwall wind farm that spotlighted cancellation decisions.
