China To Generate Electricity From Compressed Air

Ukraine Wind Energy Resilience shields the grid with wind power along the Black Sea, dispersing turbines to withstand missile attacks, accelerate clean energy transition, aid EU integration, and strengthen energy security and rapid recovery.

Key Points

A strategy in Ukraine using wind farms to harden the grid, ensure clean power, and speed recovery from missile strikes.

✅ Distributed turbines reduce single-point-of-failure risk

✅ Faster repair of substations and lines than power plants

✅ Supports EU-aligned clean energy and grid security goals

The giants catch the wind with their huge arms, helping to keep the lights on in Ukraine — newly built windmills, on plains along the Black Sea.

In 15 months of war, Russia has launched countless missiles and exploding drones at power plants, hydroelectric dams and substations, trying to black out as much of Ukraine as it can, as often as it can, even amid talk of limiting attacks on energy sites that has surfaced, in its campaign to pound the country into submission.

The new Tyligulska wind farm stands only a few dozen miles from Russian artillery, but Ukrainians say it has a crucial advantage over most of the country’s grid, helping stabilize the system even as electricity exports have occasionally resumed under fire.

A single, well-placed missile can damage a power plant severely enough to take it out of action, but Ukrainian officials say that doing the same to a set of windmills — each one tens of meters apart from any other — would require dozens of missiles. A wind farm can be temporarily disabled by striking a transformer substation or transmission lines, but these are much easier to repair than power plants.

“It is our response to Russians,” said Maksym Timchenko, CEO of DTEK Group, the company that built the turbines in the southern Mykolaiv region — the first phase of what is planned as Eastern Europe’s largest wind farm. “It is the most profitable and, as we know now, most secure form of energy.”

Ukraine has had laws in place since 2014 to promote a transition to renewable energy, both to lower dependence on Russian energy imports, with periods when electricity exports resumed to neighbors, and because it was profitable. But that transition still has a long way to go, and the war makes its prospects, like everything else about Ukraine’s future, murky.

In 2020, 12% of Ukraine’s electricity came from renewable sources — barely half the percentage for the European Union. Plans for the Tyligulska project call for 85 turbines producing up to 500 megawatts of electricity. That’s enough for 500,000 apartments — an impressive output for a wind farm, but less than 1% of the country’s prewar generating capacity.

After the Kremlin began its full-scale invasion of Ukraine in February 2022, the need for new power sources became acute, prompting deliveries such as a mobile gas turbine power plant to bolster capacity. Russia has bombarded Ukraine’s power plants and cut off delivery of the natural gas that fueled some of them.

Russian occupation forces have seized a large part of the country’s power supply, and Russia has built power lines to reactivate the Zaporizhzhia plant in occupied territory, ensuring that its output does not reach territory still held by Ukraine. They hold the single largest generator, the 5,700-megawatt Zaporizhzhia Nuclear Power Plant, which has been damaged repeatedly in fighting and has stopped transmitting energy to the grid, with UN inspectors warning of mines at the site during recent visits. They also control 90% of Ukraine’s renewable energy plants, which are concentrated in the southeast.

The postwar recovery plans Ukraine has presented to supporters including the European Union, which it hopes to join, feature a major new commitment to clean energy, even as a controversial proposal on Ukraine’s nuclear plants continues to stir debate.

U.S. Renewable Energy Record 28% signals a cleaner power grid as wind, solar, and hydroelectric output soar; EIA data shows cost-competitive clean energy reshaping the electricity mix and reducing carbon emissions across regions.

Key Points

EIA-reported April share of electricity from wind, solar, and hydro, reflecting cost-driven growth in U.S. clean power.

✅ Wind, solar additions dominated recent U.S. capacity buildouts

✅ Lower levelized costs make renewables most competitive

✅ Seasonal factors and outages lowered fossil and nuclear output

The amount of electricity generated by renewable resources hit a record 28% in April, a breakthrough number that shows how important renewable energy has become in U.S. energy markets as it surpassed coal in 2022 overall.

"It's a 'Wow' moment," said Peter Kelly-Detwiler, an energy analyst and author of "The Energy Switch," a recent book about the transition to a carbon-free energy economy.

The percentage of U.S. electricity produced by renewable energy from wind, solar and hydroelectric dams has been steadily rising, from 8.6% in April 2001 to this April's 28%. Those numbers were released this week by the U.S. Energy Information Administration, which tracks energy data for the nation.

What explains the surge?
There are several reasons. At the top is that wind and solar installations dominated U.S. energy buildouts.

"Basically, the only things we've added to the grid in the past decade are wind, solar and natural gas," said Harrison Fell, an economist and engineer at Columbia University, where he co-leads the Power Sector and Renewables Research Initiative.

That's happening for two reasons. The first is cost. Renewables are simply the most economically competitive power currently available, Kelly-Detwiler said.

In 2021, the cost of producing a megawatt-hour of electricity from a new wind turbine was $26 to $50. The same amount of electricity from the cheapest type of natural gas plant ranged from $45 to $74, according to Lazard, a financial advisory firm that publishes annual estimates of the cost of producing electricity. 

Federal and state mandates and incentives to increase the amount of clean energy used also help, Fell said, as renewables reached 25.5% of U.S. electricity recently. 

"When you do the math on what's the most profitable thing to add, it's often going to be wind and solar at this stage," he said.

Was weather a factor?
Yes. April tends to be a particularly windy month, and this spring was windier than most, Fell said.

There's also less power coming into the grid from fossil fuels and nuclear in the spring. That's because electricity demand is generally lower because of the mild weather and fossil fuel and nuclear power plants use the time for maintenance and refueling, which reduces their production, he said.

Another surprise was that in April, wind and solar power together produced more electricity than nuclear plants nationwide. 

Historically, nuclear power plants, which are carbon-neutral, have reliably produced about 20% of America's electricity. In April that number dropped to 18% while wind and solar combined stood at 19.6%.

The nuclear decrease is partly a result of the shutdown of two plants in the past year, Indian Point in New York state and Palisades in Michigan, as well as scheduled closures for maintenance.

Will the trend continue?
When all U.S. carbon-neutral energy sources are added together – nuclear, wind, hydroelectric and solar – almost 46% of U.S. electricity in April came from sources that don't contribute greenhouse gases to the environment, federal data shows.  

"It's a milestone," Kelly-Detwiler said. "But in a few years, we'll look back and say, 'This was a nice steppingstone to the next 'Wow!' moment."

First Glasgow Electric Buses will transform the Caledonia depot with 160 charging points, zero-emission operations, grid upgrades, and rapid charging, supported by Transport Scotland funding and Alexander Dennis manufacturing for cleaner urban routes by 2023.

Key Points

Electric single-deckers at Caledonia depot with 160 chargers and upgrades, delivering zero-emission service by 2023

✅ 160 charging points; 4-hour rapid recharge capability

✅ Grid upgrades to power a fleet equal to a 10,000-person town

✅ Supported by Transport Scotland; built by Alexander Dennis

First Bus will install 160 charging points and replace half its fleet with electric buses at its Caledonia depot in Glasgow.

The programme is expected to be completed in 2023, similar to Metro Vancouver's battery-electric rollout milestones, with the first 22 buses arriving by autumn.

Charging the full fleet will use the same electricity as it takes to power a town of 10,000 people.

The scale of the project means changes are needed to the power grid, a challenge highlighted in global e-bus adoption analysis, to accommodate the extra demand.

First Glasgow managing director Andrew Jarvis told BBC Scotland: "We've got to play our part in society in changing how we all live and work. A big part of that is emissions from vehicles.

"Transport is stubbornly high in terms of emissions and bus companies need to play their part, and are playing their part, in that zero emission journey."

First Bus currently operates 337 buses out of its largest depot with another four sites across Glasgow.

The new buses will be built by Alexander Dennis at its manufacturing sites in Falkirk and Scarborough.

The transition requires a £35.6m investment by First with electric buses costing almost double the £225,000 bill for a single decker running on diesel.

But the company says maintenance and running costs, as seen in St. Albert's electric fleet results, are then much lower.

The buses can run on urban routes for 16 hours, similar to Edmonton's first e-bus performance, and be rapidly recharged in just four hours.

This is a big investment which the company wouldn't be able to achieve on its own.

Government grants only cover 75% of the difference between the price of a diesel and an electric bus, similar to support for B.C. electric school buses programmes, so it's still a good bit more expensive for them.

But they know they have to do it as a social responsibility, and large-scale initiatives like US school bus conversions show the direction of travel, and because the requirements for using Low Emissions Zones are likely to become stricter.

The SNP manifesto committed to electrifying half of Scotland's 4,000 or so buses within two years.

Some are questioning whether that's even achievable in the timescale, though TTC's large e-bus fleet offers lessons, given the electricity grid changes that would be necessary for charging.

But it's a commitment that environmental groups will certainly hold them to.

Transport Scotland is providing £28.1m of funding to First Bus as part of the Scottish government's commitment to electrify half of Scotland's buses in the first two years of the parliamentary term.

Net Zero Secretary Michael Matheson said: "It's absolute critical that we decarbonise our transport system and what we have set out are very ambitious plans of how we go about doing that.

"We've set out a target to make sure that we decarbonise as many of the bus fleets across Scotland as possible, at least half of it over the course of the next couple of years, and we'll set out our plans later on this year of how we'll drive that forward."

Transport is the single biggest source of greenhouse gas emissions in Scotland which are responsible for accelerating climate change.

In 2018 the sector was responsible for 31% of the country's net emissions.

Electric bus
First Glasgow has been trialling two electric buses since January 2020.

Driver Sally Smillie said they had gone down well with passengers because they were much quieter than diesel buses.

She added: "In the beginning it was strange for them not hearing them coming but they adapt very easily and they check now.

"It's a lot more comfortable. You're not feeling a gear change and the braking's smoother. I think they're great buses to drive."

New York Offshore Wind Expansion adds Equinor's Empire Wind 2 and Beacon Wind, boosting megawatts, turbines, and grid connections for Long Island and Queens, with jobs, assembly at South Brooklyn Marine Terminal, and clean energy.

Key Points

A statewide initiative proposing new Equinor and partner projects to scale offshore wind capacity, jobs, and grid links.

✅ Adds 2,490 MW via Empire Wind 2 and Beacon Wind

✅ Connects to Nassau County and Queens grids for reliability

✅ Creates 3,000+ NY jobs with South Brooklyn Marine Terminal work

Scores more 600-foot tall wind turbines would be built off Jones Beach under a new proposal.

Norwegian energy conglomerate Equinor has bid to create another 2,500 megawatts of offshore wind power for New York state and Long Island, where offshore wind sites are being evaluated, with two projects. One, which would connect to the local electric grid in Nassau County, would more than double the number of turbines off Long Island to some 200. A second would be built around 50 miles from Montauk Point and connect to the state grid in Queens. The plan would also include conducting assembly work in Brooklyn.

In disclosures Tuesday in response to a state request for proposals, Equinor said it would bolster its already state-awarded, 819-megawatt Empire Wind project off Long Island’s South Shore with another called Empire Wind 2 that will add 1,260 megawatts. Turbines of at least 10 megawatts each would mean that the prior project’s 80 or so turbines could be joined by another 120. Equinor’s federally approved lease area off Long Island encompasses some 80,000 acres, starting 15 miles due south of Long Beach and extending east and south.

Equinor on Tuesday also submitted plans to offer a second project called Beacon Wind that would be built 50 miles from Montauk Point, off the Massachusetts South Coast area. It would be 1,230 megawatts and connect through Long Island Sound to Queens.

Equinor said its latest energy projects would generate more than 3,000 New York jobs, including use of the South Brooklyn Marine Terminal for “construction activities” and an operations and maintenance base.

The new proposals came in response to a New York State Energy Research and Development Authority bid request for renewable projects in the state. In a statement, Siri Espedal Kindem, president of Equinor Wind U.S., said the company’s plans would include “significant new benefits for New York – from workforce training, economic development, and community benefits – alongside a tremendous amount of homegrown, renewable energy.”

Meanwhile, Denmark-based Orsted, working with New England power company Eversource, has also submitted plans for a new offshore wind project called Sunrise Wind 2, a proposal that includes “multiple bids” that would create “hundreds of new jobs, and infrastructure investment,” according to a company statement. Con Edison Transmission will also work to develop transmission facilities for that project, the companies said.

Orsted and Eversource already have contracts to develop a 130-megawatt wind farm for LIPA to serve the South Fork, and an 880-megawatt wind farm for the state. All of its hundreds of turbines would be based in a lease area off the coast of Massachusetts and Rhode Island, where Vineyard Wind has progressed as a key project.

“Sunrise Wind 2 will create good-paying jobs for New York, support economic growth, and further reduce emissions while delivering affordable clean energy to Long Island and the rest of New York,” Joe Nolan, executive vice president for Eversource, said in a statement.

Electric Vehicles Lower Electricity Rates by boosting demand, enabling fixed-cost recovery, and encouraging off-peak charging that balances the grid, reduces peaker plant use, and funds utility upgrades, with V2G poised to expand system benefits.

Key Points

By boosting off-peak demand and utility revenue, EVs spread fixed costs, cut peaker use, and stabilize the grid.

✅ Off-peak charging flattens load, reducing peaker plant reliance

✅ Higher kWh sales spread fixed grid costs across more users

✅ V2G can supply power during peaks and emergencies

Electric vehicles (EVs) are gaining popularity, and it appears they might be offering an unexpected benefit to everyone – including those who don't own an EV.  A new study by the non-profit research group Synapse Energy Economics suggests that the growth of electric cars is actually contributing to lower electricity rates for all ratepayers.

How EVs Contribute to Lower Rates

The study explains several factors driving this surprising trend:

• Increased Electricity Demand: Electric vehicles require additional electricity, boosting rising electricity demand on the grid.
• Optimal Charging Times: Many EV owners take advantage of off-peak charging discounts. Charging cars overnight, when electricity demand is typically low, helps to balance state power grids and reduce the need for expensive "peaker" power plants, which are only used to meet occasional spikes in demand.
• Revenue for Utilities: Electric car charging can generate substantial revenue for utilities, potentially supporting investment in grid improvements, energy storage solutions and renewable energy projects that can bring long-term benefits to all customers.

A Significant Impact

The Synapse Energy Economics study analyzed data from 2011 to 2021 and concluded that EV drivers already contributed over $3 billion more to the grid than their associated costs. That, in turn, reduced monthly electricity bills for all customers.

Benefits May Grow

While the impact on electricity rates has been modest so far, experts anticipate the benefits to grow as EV adoption rates increase. Vehicle-to-grid (V2G) technology, which allows EVs to feed stored power back into the grid during emergencies or high-demand periods, has the potential to further optimize electricity usage patterns and create additional benefits for electric utilities and customers.

National Implications

The findings of this study offer hope to other regions seeking to increase electric vehicle adoption rates and support California's grid stability efforts, which is a key step towards reducing transportation-related greenhouse gas emissions. This news may alleviate concerns about potential electricity rate hikes driven by EV adoption and suggests that the benefits will be broadly shared.

More than Just Environmental Benefits

Electric vehicles bring a clear environmental advantage by reducing reliance on fossil fuels. However, this unexpected economic benefit could further strengthen the case for accelerating the adoption of electric vehicles. This news might encourage policymakers and the public to consider additional incentives or policies, including vehicle-to-building charging approaches, to promote the transition to this cleaner mode of transportation knowing it can yield benefits beyond environmental goals.

U.S. Solar Panel Shipments 2021 surged to 28.8 million kW of PV modules, tracking utility-scale and small-scale capacity additions, driven by imports from Asia, resilient demand, supply chain constraints, and declining prices.

Key Points

Record 28.8M kW PV modules shipped in 2021; 80% imports; growth in utility- and small-scale capacity with lower prices.

✅ 28.8M kW shipped, up from 21.8M kW in 2020 (record capacity)

✅ 80% of PV module shipments were imports, mainly from Asia

✅ Utility-scale +13.2 GW; small-scale +5.4 GW; residential led

U.S. shipments of solar photovoltaic (PV) modules (solar panels) rose to a record electricity-generating capacity of 28.8 million peak kilowatts (kW) in 2021, from 21.8 million peak kW in 2020, based on data from our Annual Photovoltaic Module Shipments Report. Continued demand for U.S. solar capacity drove this increase in solar panel shipments in 2021, as solar's share of U.S. electricity continued to rise.

U.S. solar panel shipments include imports, exports, and domestically produced and shipped panels. In 2021, about 80% of U.S. solar panel module shipments were imports, primarily from Asia, even as a proposed tenfold increase in solar aims to reshape the U.S. electricity system.

U.S. solar panel shipments closely track domestic solar capacity additions; differences between the two usually result from the lag time between shipment and installation, and long-term projections for solar's generation share provide additional context. We categorize solar capacity additions as either utility-scale (facilities with one megawatt of capacity or more) or small-scale (largely residential solar installations).

The United States added 13.2 gigawatts (GW) of utility-scale solar capacity in 2021, an annual record and 25% more than the 10.6 GW added in 2020, according to our Annual Electric Generator Report. Additions of utility-scale solar capacity reached a record high, reflecting strong growth in solar and storage despite project delays, supply chain constraints, and volatile pricing.

Small-scale solar capacity installations in the United States increased by 5.4 GW in 2021, up 23% from 2020 (4.4 GW), as solar PV and wind power continued to grow amid favorable government plans. Most of the small-scale solar capacity added in 2021 was installed on homes. Residential installations totaled more than 3.9 GW in 2021, compared with 2.9 GW in 2020.

The cost of solar panels has declined significantly since 2010. The average value (a proxy for price) of panel shipments has decreased from $1.96 per peak kW in 2010 to $0.34 per peak kW in 2021, as solar became the third-largest renewable source and markets scaled. Despite supply chain constraints and higher material costs in 2021, the average value of solar panels decreased 11% from 2020.

In 2021, the top five destination states for U.S. solar panel shipments were:

California (5.09 million peak kW)
Texas (4.31 million peak kW)
Florida (1.80 million peak kW)
Georgia (1.15 million peak kW)
Illinois (1.12 million peak kW)
These five states accounted for 46% of all U.S. shipments, and 2023 utility-scale project pipelines point to continued growth.
