US Army deploys its first floating solar array

China Compressed-Air Energy Storage enables grid flexibility using salt caverns in Jiangsu, delivering long-duration storage for wind and solar, 60 MW capacity, dispatchable power, and low-cost, safe, round-the-clock clean energy integration.

Key Points

Stores off-peak power by compressing air in salt caverns, then drives turbines on demand to balance renewables.

✅ 60 MW Jintan plant connects to grid; commercial CAES milestone

✅ Uses salt caverns; low-cost long-duration storage; high safety

✅ Balances wind and solar; improves grid flexibility and reliability

China is set to connect its first commercial compressed-air energy storage plant to the grid as it seeks more ways to harness fast-growing clean power resources, including new hydropower alongside other long-duration options such as gravity power technologies for around-the-clock use.

China Huaneng Group Co. said its Jiangsu Jintan Salt Cave project recently underwent four days of successful trials and is now ready for commercial operations. The 60-megawatt plant will be the largest compressed air energy storage plant built anywhere in the world since 1991, and the first in China outside of small-scale technology demonstration projects, as China's electricity demand patterns remain in flux, according to BloombergNEF.

The plant will use electricity at night when demand is low to pump air into an underground salt cavern. Then, when demand is high during the day, it can release the compressed air at high enough pressure to spin a turbine and produce electricity, aligning with projections that 60% electricity by 2060 could be reached according to industry outlooks.

Underground compressed air is considered one of the least costly forms of long-term energy storage and has low safety concerns, according to BloombergNEF. But its reliance on certain topographical features such as underground caverns may limit wider deployment, a challenge shared by other regions weighing large-scale storage options for reliability. It’s gained a foothold in China, with nearly four gigawatts of projects in the pipeline, while there are less than two gigawatts combined planned in the rest of the world. Shandong province said just this week in this year's work plan that it would build three projects using the technology.

The Jintan salt caves in Jiangsu, China’s second-biggest provincial economy just north of Shanghai, can store about 10 million cubic meters of gas, enough to power four gigawatts of compressed air plants, according to a Science and Technology Daily report from last year. 

Energy storage is a key part of China’s plan to build a larger and more flexible grid as it tries to peak carbon emissions before 2030 and zero them out before 2060, alongside continued nuclear energy development to stabilize baseload supply. The country is adding a world-leading amount of wind and solar power every year, but their intermittency strains grids that need to be able to deliver electricity all the time, spurring interest in green hydrogen as a flexible complement. China has set targets of 30 gigawatts of new-energy storage by 2025 and 120 gigawatts of pumped hydro storage by 2030.

Nature-friendly offshore wind energy supports climate neutrality by reducing greenhouse gases while safeguarding marine biodiversity through EU marine spatial planning, ecosystem-based approaches, cross-border coordination, and zero-use zones for resilient seas.

Key Points

An approach to offshore wind that cuts emissions while respecting ecological limits and protecting marine biodiversity.

✅ Aligns buildout with ecological limits and marine spatial plans

✅ Minimizes noise, collision, and habitat loss for sensitive species

✅ Coordinates EU-wide monitoring, data, and cross-border siting

Offshore wind power can help reduce greenhouse gas emissions, but it poses risks for the seas. Germany will hold the EU Council Presidency and the North Sea Energy Cooperation Presidency in 2020. What must be done to contain the climate and species crises, as it were?

Offshore wind power is an important regenerative energy source with a $1 trillion market outlook in the coming decades. However, the construction, operation and maintenance of the systems put marine mammals, birds and fish at considerable risk. Photo: Siemens AG

In order to achieve the German and EU climate and energy goals by 2030 and climate neutrality by 2050, we need a nature-friendly energy transition. At present, the European energy system is largely based on fossil fuels. This is changing, as renewables surge across Europe for end consumers and industry and the large-scale electrification of the energy consumption sectors. Offshore wind energy is an element for future power generation.

A nature-friendly energy transition is only possible if energy consumption is reduced and energy efficiency is maximized in all applications and sectors. Emissions reductions through offshore wind energy In 2019, Europe had an installed offshore wind energy capacity of around 22 gigawatts from 5,047 grid-connected wind turbines in twelve countries. In Germany, the nominal output of the offshore wind turbines feeding into the German power grid was around 7.5 gigawatts, with clean energy accounting for about 50% of electricity nationwide. The wind blows much stronger and more steadily at sea than on land.

The power capacity of the turbines has also almost doubled in the last five years, which has led to a higher energy yield. Offshore wind energy is a building block for replacing fossil fuels, and markets like the U.S. offshore sector are about to soar as well. Wind turbines at sea provide electricity almost every hour of the year and have operating hours that are as high as conventional power plants. They can contribute to significant reductions in CO2 emissions and to mitigate the climate crisis.

It must be ensured that offshore wind turbines and parks as well as the grid infrastructure make a positive contribution to climate protection through their expansion and that the overall condition of marine ecosystems improves. The expansion of offshore wind energy is necessary from the point of view of climate science and must take place within the framework of the ecological load limits and under nature conservation aspects.

Seas and marine ecosystems suffer from years of overfishing, pollution and industrial use. The conservation status of sea birds, marine mammals and fish stocks is poor. Ecosystem services and productivity of the oceans are decreasing as a result of massive species extinction and unfavorable habitats. Changes in sea temperature, oxygen levels and acidification of the oceans reduce their resilience to the climate crisis.

The latest reports from the European Environment Agency show in black and white that the good environmental status and other goals of the Marine Strategy Framework Directive are not being achieved. The primary goal must therefore be to meet the obligations of the Marine Strategy Framework Directive and the EU nature conservation directives.

With the expansion of offshore wind energy, the pressure on the already polluted marine ecosystems is increasing. Offshore wind turbines also harbor risks for marine ecosystems, especially if they are built in unfavorable locations. Studies show harmful effects on marine mammals, birds, fish and the ocean floor. In Europe, where wind power investments hit $29.4 billion last year, a regulatory framework must be created for the expansion of offshore wind energy within the ecological limits and taking into account zero-use zones. The European Union urgently needs to take coherent measures for healthy and resilient seas.

New strategy of the European Commission The EU Commission plans to present a strategy for the expansion of renewable energies at sea on November 18, 2020.

The strategy will address the opportunities and challenges associated with the expansion of renewable energies at sea, such as effects on energy networks and markets, management of the maritime space, the technological transfer of research projects, regional and international cooperation and industrial policy dimensions, as well as political headwinds in some countries that can affect project pipelines. NABU welcomes the strategy, but worries about insufficient consideration of marine protection, ecological load-bearing capacity and the marine spatial planning that regulates interests in the use of the sea. All EU member states have to submit their marine spatial planning plans by March 2021.

Conclusions of the European Council Shortly before the end of 2020, the European Council plans to adopt conclusions for cooperation among European member states on the subject of offshore wind energy and other renewable energy sources at sea. It is important that the planning and development of offshore wind energy is coordinated across national borders, including alignment with the UK's offshore wind growth, also to protect marine ecosystems.

However, the ecosystem approach must not be left out. It must be ensured that the Council conclusions focus on the implementation of EU marine and nature conservation directives for the expansion of offshore wind energy within the load limits. EU-wide monitoring systems can help protect marine species and ecosystems. Germany holds the EU Council Presidency and the North Sea Energy Cooperation Presidency for 2020 and can make a decisive contribution.

NABU demands on offshore wind energy in Europe Expansion targets for offshore wind energy across Europe should be based on the ecological load limits of the seas. Development of concrete concepts for the ecological upgrading of areas in marine spatial planning and operationalization of the ecosystem-based approach.

For the nature-friendly expansion of offshore – Wind energy systems must take into account avoidance distances from seabirds to turbines, habitat loss, collision risks and cumulative effects. Implementation / obligation to sensitivity analyzes – they allow targeted conclusions about the best possible locations for offshore wind energy without conflicts with marine protection.

Targeted keeping of areas free for species and their Habitats of anthropogenic use – this increases planning security and can lower investment thresholds for EU funding programs. Ensuring regional cooperation between the European member states for nature Protection and with the involvement of nature conservation authorities – after all, the marine ecosystem does not stop at borders.

Adjustment of priorities: If offshore wind energy is prioritized over other renewable energy sources across Europe, other industrial forms of use of the seas must be given a lower priority.

Electric Vehicles deliver longer range, faster charging, and broader price options, with incentives and lease deals reducing costs; evaluate performance, home charging, road trip needs, and vehicle types like SUVs, pickups, and vans.

Key Points

Electric vehicles are battery-powered cars that cut costs, boost performance, and charge at home or at fast stations.

✅ Longer range and faster charging reduce range anxiety

✅ Lower operating costs vs gas: fuel, maintenance, incentives

✅ Home Level 2 charging recommended; plan for road trips

Electric cars now drive farther, charge faster and come in nearly every price range. But when GMC began promoting its Hummer EV pickup truck to be released this year, it became even clearer that electric cars are primed to go mainstream for many buyers.

Once the domain of environmentalists, then early adopters, electric vehicles may soon have even truck bros kicking the gasoline habit, though sales are still behind gas cars in many markets.

With many models now available or coming soon — and arriving ahead of schedule for several automakers — including a knockoff of the lovable Volkswagen Microbus — you may be wondering if it’s finally time to buy or lease one.

Here are the essential questions to answer before you do.

(Full disclosure: I’m a convert myself after six years and 70,000 gas-free miles.)

1. Can you afford an electric car?
Electric vehicles tend to be pricy to buy but can be more affordable to lease. Finding federal, state and local government incentives can also reduce sticker shock. And, even if the monthly payment is higher than a comparable gas car, operating costs are lower.

Gas vehicles cost an average of $3,356 per year to fuel, tax and insure, while electric cost just $2,722, according to a study by Self Financial, and Consumer Reports finds EVs save money in the long run too. Find out how much you can save with the Department of Energy calculator.

2. How far do you need to drive on a single charge?
Although almost 60 percent of all car trips in America were less than 6 miles in 2017, according to the Department of Energy, the phrase “range anxiety” scared many would-be early adopters.

Teslas became popular in part because they offered 250 miles of range. But the range of many electric vehicles between charges is now over 200 miles; even the modestly priced Chevrolet Bolt can travel 259 miles on a single charge.

Still, electric vehicles have a “road trip problem,” according to Josh Sadlier, director of content strategy for car site Edmunds.com. “If you like road trips, you almost have to have two cars — one for around town and one for longer trips,” he says.

3. Where will you charge it?
If you live in an apartment without a charging station, this could be a deal breaker.

The number of public chargers increased by 60 percent worldwide in 2019, according to the International Energy Agency. While these stations — some of which are free — are more available, most electric vehicle owners install a home station for faster charging.

Electric vehicles can be charged by plugging into a common 120-volt household outlet, but it’s slow, and understanding charging costs can help you plan home use. To speed up charging, many electric vehicle owners wind up buying a 240-volt charging station and having an electrician install it for a total cost of $1,200, according to the home remodeling website Fixr.

4. What will you use the car for?
While there are a few luxury electric SUVs on the market, most electric vehicles are smaller sedans or hatchbacks with limited cargo capacity. However, the coming wave of electric cars are more versatile, and many experts expect that within a decade these options will be commonplace, including vans, such as the Microbus, and trucks, such as an electric version of the popular Ford F-150 pickup.

5. Do you enjoy performance?
This is where electric vehicles really shine. According to automotive experts, electric cars beat their gas counterparts in these ways:

Immediate response with great low-end acceleration, particularly in the 0-30 mph range.
Sure-footed handling due to the heavy battery mounted under the car, giving it a low center of gravity.
No “shift shock” from changing gears in a conventional gas car’s transmission.
Little noise except from the wind and tires.

Other factors
Once you consider the big questions, here are other reasons to make an electric car your next choice:

Reduced environmental guilt. There is a persistent myth that electric vehicles simply move the emissions from the tailpipe to the power generating station. Yes, producing electricity produces emissions, but many electric vehicle owners charge at night when much of the electricity would otherwise be unused. According to research published by the BBC and evidence that they are better for the planet in many scenarios electric cars reduce emissions by an average of 70 percent, depending on where people live.

Less time refueling. It takes only seconds to plug in at home, and the electric vehicle will recharge while you’re doing other things. No more searching for gas stations and standing by as your tank gulps down gasoline.

No oil changes. Dealers like a constant stream of drivers coming in for oil changes so they can upsell other services. Electric vehicles have fewer moving parts and require fewer trips to the dealership for maintenance.

Carpool lanes and other perks. Check your state regulations to see if an electric vehicle gets you access to the carpool lane, free parking or other special advantages.

Enjoy the technology. Yes, electric vehicles are more expensive, but they also tend to offer top-of-the-line comfort, safety features and technology compared with their gas counterparts.

UK Petrol Shortages Drive EV Adoption as fuel crisis spurs electric vehicles, plug-in car demand, home charging, lower running costs, zero-emission mobility, ULEZ compliance, accelerating the shift from diesel to battery EVs.

Key Points

Fuel shortages push drivers to EVs, boosting inquiries and sales while highlighting the convenience of home charging.

✅ Surge in EV dealer inquiries and test drives

✅ Home charging avoids queues and fuel shortages

✅ Policy signals: ULEZ expansion, 2030 ICE ban

Sellers of plug-in vehicles say petrol shortages are driving people to adopt the new technology as the age of electric cars accelerates worldwide.

As petrol stations in parts of the UK started running out of fuel on Friday, business at Martin Miller’s electric car dealership in Guildford, Surrey, started soaring.

After what ended up being his company EV Experts busiest day ever, interest does not appear to be dying down. This week the diary is booked up with test drives and the business is low on stock amid supply constraints.

“People buy electric cars for environmental reasons, for cost-saving reasons and because the technology’s great, even though higher upfront prices remain a concern,” he said. “But Friday was one of those moments where people said, ‘Do you know what, this is a sign that we need to go electric’.”

While scenes of chaos play out at petrol stations across the country amid shortages, for many electric vehicle (EV) dealers the fuel crisis has led to an unexpected surge in inquiries and sales, even as some question an electric-car revolution narrative today.

EVA England, a non-profit representing new and prospective EV drivers, reports a rise in electric car inquiries and in interest at EV dealers, particularly in the last week.

“Saturday was bonkers but Friday even surpassed that, it was very strange,” said Miller, who founded his company four years ago. “I’ve now got trade-in cars with no petrol to move them.”

Along with existing factors such as the expansion of London’s ultra-low emission zone, the fuel crisis has proved to be another trigger point, he said. “People were using it as ‘this is the moment where I’m not going to put this off any longer’.”

The EV market is no longer the preserve of innovators and early adopters, he said, with the most popular models the Nissan Leaf, Volkswagen ID 3 and Jaguar I-Pace.

Ben Strzalko, the owner of Electric Cars UK in Leyland, Lancashire, said that as a small business it would take a few months to feel the knock-on effect of the fuel crisis on sales.

But every time there are problems with petrol or diesel, he said they acted as “one more tick for people making that transition to electric cars”.

He said “a lot of electric car owners will be chuffed to bits this last week” being able to plug in their cars at home. And as an EV driver himself, he admitted feeling a little smug as he drove past queues of 20 cars outside petrol stations over the weekend in his Tesla.

Matt Cleevely, the owner of Cleevely Electric Vehicles in Cheltenham, Gloucestershire, which specialises in used EVs, had a surge of inquiries over the weekend and on Monday morning from customers citing the fuel crisis as a reason for switching to electric.

He expects enthusiasm to continue rising, with petrol shortages adding “fuel to the fire”.

Although he feels sorry for non-EV drivers who have been unable to get fuel, he said as an electric car owner it was “very nice” not to have to worry about where to get petrol at the weekend.

“It’s very convenient that we’ve been able to just fuel up on our driveway. It’s one of the biggest pros of having an electric vehicle.”

The National Franchised Dealers Association also said multiple dealers have reported a spike in EV enquiries since the start of the crisis.

The Society of Motor Manufacturers and Traders reported “bumper growth” in the sale of plug-in cars in July, reflecting broader global market growth in recent years, with battery electric vehicles comprising 9% of sales. Plug-in hybrids accounted for 8% of sales and hybrid electric vehicles nearly 12%. Also in July, more electric vehicles were registered than diesel for the second consecutive month.

The UK has pledged to ban the sale of new petrol and diesel cars by 2030 and of new hybrids by 2035, a timeline that aligns with expectations that within a decade most driving could be electric.

Warren Philips, the volunteer communities director at EVA England, said the tipping point for EVs had already been reached but the fuel crisis “underlines how electric cars could work for the majority of people”.

He added: “The interest is already there, this just adds to it. And going forward with things like Cop26, with the climate crisis, with the cost of fuel probably going to rise … people will start looking at electric cars where you just skip that entire step.”

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

Key Points

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

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

✅ Onshore wind costs roughly 44 percent less than natural gas

✅ Policy and tax credits accelerate renewables and cut power prices

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

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

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

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