Founded in Dresden in the early 1990s, Germany’s Solarwatt quickly became an emblem of Europe’s renewable energy ambitions and bold plan to build a solar power industry. Its opening of a new solar panel plant in Dresden in late 2021 was hailed as a small victory in the battle to wrestle market share from the […]

India has ramped up its wind and solar energy. It now needs to expand places to store it
At a Coca-Cola factory on the outskirts of Chennai in southern India a giant battery powers machinery day and night, replacing a diesel-spewing generator. It’s one of just a handful of sites in India powered by electricity stored in batteries, a key component to fast-tracking India’s energy transition away from dirty fuels. The country’s lithium […]
Study shows new truck efficiency standards may reduce expected energy savings
Deliveries are getting faster than ever in the U.S., but the faster movement of goods is undercutting the country’s climate progress. In a new study published July 18 in the journal Nature Energy, a CU Boulder researcher and his collaborator estimate that federal regulations aimed at enhancing heavy-duty trucks’ energy efficiency could be as much as […]
California Residents Increasingly Pairing Battery Storage with Solar Installations
California residents are increasingly pairing battery storage with solar installations, according to the latest preliminary data in our Monthly Electric Power Industry Report. The share of new residential solar photovoltaic systems paired with batteries has increased since we began collecting data in October 2023. In April 2024, more than 50% of residential solar photovoltaic installations […]
GE Vernova enters into innovation agreement with German grid transmission operators to develop key HVDC technology for future electricity network
GE Vernova’s Electrification business has announced that is has entered into a research & development contract with four German Transmission System Operators (TSOs) – TenneT TSO GmbH, 50Hertz Transmission GmbH, Amprion GmbH and Transnet BW GmbH – for the design and engineering of a Multi-Terminal/Multi-Hub High-Voltage Direct Current (HVDC) connection solution. The R&D agreement marks […]
A strategy to enhance the stability of perovskite solar cells under reverse bias conditions
If an individual solar cell is shaded and other cells in the same module are not, the sunlit cells can try to drive current through the shaded cell, resulting in an increase in temperature and potential damage to the cells. These conditions put the shadowed cell under a condition known as reverse bias, which makes […]
Why Solar Stocks Fell Sharply on Monday
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 […]
Offshore wind turbines offer path for clean hydrogen production
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 […]
Hydrogen flight looks ready for take-off with new advances
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 […]
Labour’s ‘rooftop revolution’ to deliver solar power to millions of UK homes
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 […]
