In a new study assessing how climate change might alter hydropower generation across the continental United States, researchers show that except for some parts of the Southwest, hydropower generation is expected to rise in the future. The analysis also shows that in the Pacific Northwest in the future, less water will be stored in the […]

Imagine if Australian cities became major producers of clean energy, rather than relying on far-flung solar and wind farms. Far fetched? Hardly. Our cities and towns are full of warehouses, commercial areas, shopping centers and factories. These types of buildings have one very important underutilized resource—large expanses of unoccupied rooftops, perfect for solar and battery […]

Though 2023 was a relatively slow year for new wind power deployment in the United States, the industry continues to see growth, solid performance, expanding supply chains, and attractive prices, according to a report prepared for the U.S. Department of Energy (DOE) by Lawrence Berkeley National Laboratory (Berkeley Lab). With power sales prices ranging from […]

Researchers have produced the world’s first flexible “solar panel” that is thin enough to coat on other objects so they can double as a portable source of energy. A breakthrough approach allowed scientists to create solar cells 150 times thinner than existing silicon-based panels, without sacrificing any of their energy-generating capabilities. These panels could eventually […]

The blades of propellers and wind turbines are designed based on aerodynamics principles that were first described mathematically more than a century ago. But engineers have long realized that these formulas don’t work in every situation. To compensate, they have added ad hoc “correction factors” based on empirical observations. Now, for the first time, engineers […]

Sidewalks lining new neighborhoods across the southern U.S. could soon be lit by solar-powered streetlights made by a startup company in Tampa. Streetleaf, headquartered in Tampa with about 15 employees, announced that it’s inked a deal with the nation’s largest homebuilder, D.R. Horton. Streetleaf will provide its streetlights for some of D.R. Horton’s new developments […]

The federal government issued on Monday the nation’s first floating offshore wind research lease to the state of Maine, comprising about 23 square miles (60 square kilometers) in federal waters. The state requested the lease from the federal Bureau of Ocean Energy Management for a floating offshore wind research array with up to a dozen […]

Operators cut the ribbon on Friday for a new utility-scale battery, which is expected to keep renewable energy projects in the area running more consistently while reducing strain on the electrical grid during peak usage times. Sixteen white blocks, roughly the size of shipping containers, hummed quietly on Friday as members of Vermont Electric Cooperative, […]

When he first bought his Toyota Mirai in 2022, Ryan Kiskis was a happy man. He loved the idea of applying cutting edge hydrogen fuel cell technology to environmental consciousness. “It’s a great car,” he said. “My background is an engineer, I’m a huge automotive fan, and I felt the the world was finally catching […]

To reduce carbon emissions and mitigate climate change on Earth, governments and companies worldwide have been investing in the electrification of both public transport and private vehicles. China is among the countries that started exploring the electrification of transportation, starting with the introduction of electric buses (EBs). Despite its predicted advantages for reducing carbon emissions, […]
