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.

Tesla prepares to bring its electric cars to South America

Tesla Chile Market Entry signals EV expansion into South America, with a Santiago country manager, service technicians, and advisors, leveraging lithium supply, competing with BYD, and preparing sales, service, and charging infrastructure.

 

Key Points

Tesla will enter Chile to launch EV sales, service, and charging from Santiago, opening its South America expansion.

✅ Country manager role based in Santiago to lead market launch

✅ Focus on EV sales, service centers, and charging infrastructure

✅ Leverages Chile's lithium ecosystem; competes with BYD

 

Tesla is preparing to bring its electric cars to South America, according to a new job posting in Chile.

It has been just over a decade since Tesla launched the Model S and significantly accelerated EV inflection point in the deployment of electric vehicles around the world.

The automaker has expanded its efforts across North America, where the U.S. EV tipping point has been reached, and most countries in Europe, and it is still gradually expanding in Asia.

But there’s one continent that Tesla hasn’t touched yet: South America, even as global EV adoption raced to two million in five years.

It sounds like it is about to change.

Tesla has started to promote a job posting on LinkedIn for a country manager in Chile, aligning with international moves like UK expansion plans it has signaled.

The country manager is generally the first person hired when Tesla expands in a new market.

The job is going to be based in Santiago, the capital of Chile, where the company is also looking for some Tesla advisors and service technicians.

Chile is an interesting choice for a first entry into the South American market. The Chilean auto market consists of only about 234,000 vehicles sold year-to-date and that’s down 29% versus the previous year.

That’s roughly the number of vehicles sold in Brazil every month.

While the size of the auto market in the country is small, there’s a strong interest for electric vehicles as the EV era arrives ahead of schedule there, which might explain Tesla’s foray.

The country is rich in lithium, a critical material for EV batteries, where lithium supply concerns have also emerged, which has helped create interest for electric vehicles in the country. The government also announced an initiative to allow for only new sales of electric vehicles in the country starting in 2035.

Tesla’s Chinese competitor BYD has set its sight on the South American market by bringing its cheaper China-made EVs to the market, part of a broader Chinese EV push in Europe as well, but now it looks like Tesla is willing to test the market on the higher-end.

China's electric carmakers make their move on Europe

Chinese EV Makers in Europe target the EU market with electric SUVs, battery swapping, competitive pricing, and subsidies, led by NIO, Xpeng, MG, and BYD, starting in Norway amid Europe's zero-emissions push.

 

Key Points

Chinese EV makers expanding into EU markets with tech, pricing, and lean retail to gain share.

✅ Early launches in Norway leverage EV incentives

✅ Compete via battery swapping, OTA tech, and price

✅ Mix of importers, online sales, and lean dealerships

 

China's electric carmakers are darting into Europe, hoping to catch traditional auto giants cold and seize a slice of a market supercharged by the continent's EV transition towards zero emissions.

Nio Inc (NIO.N), among a small group of challengers, launches its ES8 electric SUV in Oslo on Thursday - the first foray outside China for a company that is virtually unheard of in Europe even though it's valued at about $57 billion.

Other brands unfamiliar to many Europeans that have started selling or plan to sell cars on the continent include Aiways, BYD's (002594.SZ) Tang, SAIC's (600104.SS) MG, Dongfeng's VOYAH, and Great Wall's (601633.SS) ORA.

Yet Europe, a crowded, competitive car market dominated by famous brands, has proved elusive for Chinese carmakers in the past. They made strategic slips and also contended with a perception that China, long associated with cheap mass-production, could not compete on quality.

Indeed, Nio Chief Executive William Li told Reuters he foresees a long road to success in a mature market where it is "very difficult to be successful".

Chinese carmakers may need up to a decade to "gain a firm foothold" in Europe, the billionaire entrepreneur said - a forecast echoed by He Xiaopeng, CEO of electric vehicle (EV) maker Xpeng (9868.HK) who told Reuters his company needs 10 years "to lay a good foundation" on the continent.

These new players, many of which have only ever made electric vehicles, believe they have a window of opportunity to finally crack the lucrative market.

While electric car sales in the European Union more than doubled last year and jumped 130% in the first half of this year, even as threats to the EV boom persist, traditional manufacturers are still gradually shifting their large vehicle ranges over to electric and have yet to flood the thirsty market with models.

"The market is not that busy yet, if you compare it with combustion-engine models where each of the major carmakers has a whole range of vehicles," said Alexander Klose, who heads the foreign operations of Chinese electric vehicle maker Aiways.

"That is where we think we have an opportunity," he added on a drive around Munich in a U5, a crossover SUV on sale in Germany, the Netherlands, Belgium and France, where new EV rules are aimed at discouraging purchases of Chinese models.

The U5 starts at 30,000 euros ($35,000) in Germany - below the average new car price and most local EV prices - before factoring in 9,000 euros in EV subsidies, though France's EV incentives have tightened for Chinese models - and comes in just four colours and two trim levels to minimize costs.

'GERMAN PEOPLE BUY GERMAN CARS'
As Chinese carmakers gear up to enter Europe, they are trying out different business models, from relying on importers, low-cost retail options or building up more traditional dealerships.

The new reality that top Western carmakers like BMW (BMWG.DE) and Tesla Inc (TSLA.O) now produce cars in technological powerhouse China, where the EV market is intensely competitive, has likely undermined past perceptions of low quality workmanship - though they can be hard to shake.

Antje Levers, a teacher who lives in western Germany near the Dutch border, and her husband owned a diesel Chevrolet Orlando but wanted a greener option. They bought an Aiways U5 last year after plenty of research to fend off criticism for not buying local, and loves its handling and low running costs.

She said people had told her: "You can't buy a Chinese car, they're plastic and cheap and do not support German jobs." But she feels that is no longer true in a global car industry where you find German auto parts in Chinese cars and vice versa.

"German people buy German cars, so to buy a Chinese car you need to have a little courage," the 47-year-old added. "Sometimes you just have to be open for new things."

NIO LANDS IN NORWAY WITH NOMI
Nio launches its ES8 electric SUV alongside a NIO House - part-showroom, part-cafe and workspace for customers in the capital of Norway, a country that's also the initial base for Xpeng.

Norwegian state support for EVs has put the country at the forefront of the shift to electric. It makes sense as a European entry point because customers are used to electric vehicles so only have to be sold on an unknown Chinese brand, said Christina Bu, secretary general of the Norwegian EV Association.

"If you go to another European country you may struggle to sell both," said Bu, adding that her organisation has talked extensively with a number of Chinese EV makers keen to learn market specifics and consumer culture before launching there.

She is uncertain, though, how consumers will react to Nio's approach of swapping out batteries for customers rather than stopping to charge them, a contrast to other EV battery strategies in the industry, or the carmaker's strategy of leasing rather than selling batteries to customers.

"But where the Chinese are really at the forefront is the technology," she added, referring in particular to Nomi, the digital assistant in the dashboard of Nio's cars.

NEWCOMERS' STRATEGIES DIVERGE
One size does not fit all. While Nio and Xpeng have been hiring staff building up their organizations in Norway, SAIC's MG works through a car importer to sell cars in a handful of European markets.

Aiways is trying an lower-cost approach to selling cars in Europe, though Klose says it varies by market.

In Germany, for instance, the company sells its cars through Euronics, an association of independent electronics retailers, rather than building traditional dealerships.

It aims to sell across the EU by next year and to enter the U.S. market by 2023, said Klose, a former Volvo and Ford executive.

Past failed attempts by Chinese carmakers to conquer Europe are unlikely to hurt Chinese EV makers today, as consumers have grown accustomed to electronics coming from China, he added.

Such failures included Brilliance in 2007, whose vehicle received one out of five stars in a German car crash test, damaging the brand.

"The fact there are more Chinese carmakers entering the market will also help us, as it will make Chinese brands more accepted by consumers," Klose said.

Selling cars to Europeans is a "tough business, especially if your product isn't well known," said Arnie Richters, chairman of Brussels-based industry group Platform for Electromobility.

"But if they bring a lot of innovation they have a lot of opportunity."

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

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

 

Key Points

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

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

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

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

 

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

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

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

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

Manitoba has clean energy to help neighboring provinces

East-West Power Transmission Grid links provinces via hydroelectric interconnects, clean energy exports, and reliable grid infrastructure, requiring federal funding, multibillion-dollar transmission lines, and coordinated planning across Manitoba, Saskatchewan, Ontario, and Newfoundland.

 

Key Points

A proposed interprovincial grid to share hydro power, improve reliability, and cut emissions with federal funding.

✅ Hydroelectric exports from Manitoba to prairie and eastern provinces

✅ New interconnects and transmission lines require federal funding

✅ Enhances grid reliability and supports coal phase-out

 

Manitoba's energy minister is recharging the idea of building an east-west power transmission grid and says the federal government needs to help.

Cliff Cullen told the Energy Council of Canada's western conference on Tuesday that Manitoba has "a really clean resource that we're ready to share with our neighbours" as new hydro generation projects, including new turbines come online.

"This is a really important time to have that discussion about the reliability of energy and how we can work together to make that happen," said Cullen, minister of growth, enterprise and trade.

"And, clearly, an important component of that is the transmission side of it. We've been focused on transmission ... north and south, and we haven't had that dialogue about east-west."

Most hydro-producing provinces currently focus on exports to the United States, though transmission constraints can limit incremental deliveries.

Saskatchewan Energy Minister Dustin Duncan said his province, which relies heavily on coal-fired electricity plants, could be interested in getting electricity from Manitoba, even as a Manitoba Hydro warning highlights limits on serving new energy-intensive customers.

"They're big projects. They're multibillion-dollar projects," Duncan said after speaking on a panel with Cullen and Alberta Energy Minister Margaret McCuaig-Boyd.

"Even trying to do the interconnects to the transmission grid, I don't think they're as easy or as maybe low cost as we would just imagine, just hooking up some power lines across the border. It takes much more work than that."

Cullen said there's a lot of work to do on building east-west transmission lines if provinces are going to buy and sell electricity from each other. He suggested that money is a key factor.

"Each province has done their own thing in terms of transmission within their jurisdiction and we have to have that dialogue about how that interconnectivity is going to work. And these things don't happen overnight," he said.

"Hopefully the federal government will be at the table to have a look at that, because it's a fundamental expense, a capital expense, to connect our provinces."

The 2016 federal budget said significant investment in Canada's electricity sector will be needed over the next 20 years to replace aging infrastructure and meet growing demand for electricity, with Manitoba's demand potentially doubling over that period.

The budget allocated $2.5 million over two years to Natural Resources Canada for regional talks and studies to identify the most promising electricity infrastructure projects.

In April, the government told The Canadian Press that Natural Resources Canada has been talking with ministry representatives and electric utilities in the western and Atlantic provinces.

The idea of developing an east-west transmission grid has long been talked about as a way to bring energy reliability to Canadians.

At their annual meeting in 2007, Canada's premiers supported development and enhancement of transmission facilities across the country, although the premiers fell short of a firm commitment to an east-west energy grid.

Manitoba, Ontario and Newfoundland and Labrador are the most vocal proponents of east-west transmission, even as Quebec's electricity ambitions have reopened old wounds in Newfoundland and Labrador.

Manitoba and Newfoundland want the grid because of the potential to develop additional exports of hydro power, while Ontario sees the grid as an answer to its growing power needs.

25.5% Of US Electricity Coming From Renewable Energy

US Renewable Energy Growth drives the US electricity mix as wind, solar, and hydropower rise while coal, natural gas, and nuclear decline, boosting market share month over month and year over year across the grid.

 

Key Points

US Renewable Energy Growth tracks rising wind, solar, and hydro shares in the mix as coal, gas, and nuclear decline.

✅ Wind and solar surpass nuclear in April share

✅ Renewables reach 29.3% of US electricity in April

✅ Coal and natural gas shares trend lower since 2020

 

Electricity generated by renewable energy sources continues to grow month over month and year over year in the United States. In April 2022, the share of US electricity coming from renewable energy was up to 29.3%, surpassing a record April level reported previously in national data. That was up from 24.8% in April 2020 and 25.7% in April 2021.

Looking at the first four months of the year, renewables provided 25.5% of US electricity, and were the second-most U.S. source in 2020 as well, while the figure for January–April 2020 was 21.7% and the figure for January–April 2021 was 22.5%.

Coal power (20.2% of US electricity) was down year over year in this time period (from 22% in January–April 2021), even as renewables surpassed coal in 2022 nationwide, but is admittedly still a bit higher than it was in January–April 2020 (16.8%).

Electricity from natural gas is also down year over year, but only very slightly (34.7% for both years). Though, it has dropped significantly since January–April 2020 (39.6%).

Electricity from nuclear power continued to take a steady, step-by-step tumble.

Wind & Solar Power Growth Strong
As reported earlier, April was the first month that wind and solar power provided more electricity than nuclear across the United States. Wind and solar power provided 21% of US electricity, while nuclear power provided 17.8% of US electricity (coal, incidentally, also provided 17.8% of US electricity, but wind and solar had provided more electricity than coal in some previous months as well).

Wind and solar power’s combined market share for the first four months of the year was up from just 14.6% in 2020 and 18.4% in 2021.

Looking at their growth year over year, you can see strong and continuous expansion of solar-provided electricity and wind-provided electricity, amid favorable government plans that have supported deployment.

Solar grew from 2.9% in January–April 2020 to 3.6%in January–April 2021 to, eventually, 4.4% in January–April 2022, with solar's 2022 share rising to 4.7% for the full year. Wind rose from 9.2% to 10.3% to 12.2%.

Together, wind and solar were up from 12.1% in January–April 2020 to 13.9% in January–April 2021, reflecting a surge in wind power within the U.S. electricity mix over this period, to 16.7% January–April 2022.

Hydropower (6.5%) is holding approximately the same position as the same period in 2021 (6.5%), but it is down a significant chunk from April 2020 (8.2%).

UK Renewable energy projects worth billions stuck on hold

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

 

Key Points

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

✅ Up to 15-year waits for grid connections

✅ Over £200bn projects stuck in the queue

✅ Threatens zero-carbon electricity by 2035

 

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

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

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

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

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

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

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

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

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

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