Downbeat news from SolarEdge (SEDG) weighed on solar-energy shares Monday, with stocks falling across the sector. FirstSolar (FSLR) stock, which had jumped in May amid enthusiasm for the sector’s prospects to provide the energy needed to power developments in artificial intelligence, fell 8.5% and was among the S&P 500’s biggest losers on the day. Its […]

Using electricity generated by offshore wind turbines as one pathway to split water to produce clean hydrogen may make economic sense, particularly along the U.S. Atlantic Coast and in the Gulf of Mexico, according to researchers at the National Renewable Energy Laboratory (NREL). The economics work best in regions where the water is not as […]

The possibility of hydrogen-powered flight means greater opportunities for fossil-free travel, and the technological advances to make this happen are moving fast. New studies from Chalmers University of Technology, in Sweden, show that almost all air travel within a 750-mile radius (1,200 km) could be made with hydrogen-powered aircraft by 2045, and with a novel […]

Keir Starmer’s Labour government unveils plans for a “rooftop revolution” today that will see millions more homes fitted with solar panels in order to bring down domestic energy bills and tackle the climate crisis. The energy secretary, Ed Miliband, also took the hugely controversial decision this weekend to approve three massive solar farms in the […]

All of the electricity consumed by Amazon’s operations, including its data centers, was matched with 100% renewable energy in 2023. In 2019, we set a goal to match all of the electricity consumed across Amazon’s global operations—including our data centers, corporate buildings, grocery stores and fulfillment centers—with 100% renewable energy by 2030. Today, we’re proud […]

China is building almost twice as much wind and solar energy capacity as every other country combined, research published Thursday showed. The world’s second-largest economy is the biggest emitter of the greenhouse gases that drive climate change. China has committed to bring carbon emissions to a peak by 2030 and to net zero by 2060. […]

Scientists say they have found a way to cool buildings that will reduce dependence on energy-hungry air conditioners. They do not claim their design would keep buildings cool with virtually no energy requirements but confirm that once their method is adopted it could lower indoor temperature by 0.7 degrees centigrade. The study published in the […]

Solar power panels have long seemed an appealing option in California, a state with lots of sunny days that adores its electronic gadgetry and environment, yet is saddled with the highest residential electricity rates in the continental U.S. But how much does going solar shave off those electricity bills? A major new study by scientists […]

Scientists at the City University of Hong Kong (CityUHK) have developed highly efficient, printable and stable perovskite solar cells to achieve carbon neutrality and promote sustainable development. The new type of perovskite solar cells can be mass-produced at a speed comparable to newspaper printing, with a daily output of up to 1,000 solar panels. Owing […]

Hawaiian Electric is gearing up for a transformative decade on Maui, as the utility company plans to retire 88 megawatts (MW) of its fossil fuel firm generators, or roughly 35% of the firm generator capacity on Maui. This major overhaul is driven by state environmental regulations and difficulties in sourcing parts for aging generators, many […]
