Replacing the burning of fossil fuels in our residential and commercial buildings with clean electricity is a crucial step to protecting public health and eliminating climate pollution. Multiple studies, including RMI’s “The Economics of Electrifying Buildings” and E3’s “Residential Building Electrification in California”, have shown that using efficient electric heat pumps rather than gas-fired appliances is cost effective…

Dubai Airports says the system will produce 7,483,500 kilowatt hours of energy per year. This will help to cut carbon emissions by more than 3,000 metric tonnes annually. A solar energy system made up of 15,000 photovoltaic panels has been installed at Dubai International airport. In an announcement earlier this week, Dubai Airports said the…

The UK’s South Western Railway is about to launch a new type of solar energy project that will power trains using solar panels — without first distributing that power to the electrical grid. South Western Railway is hosting an event today in conjunction with solar railway organization Riding Sunbeams at Aldershot Station near London that…

More than 21,000 solar panels will be installed on the rooftops of six CapitaLand buildings by the end of this year in a partnership with Sembcorp Industries, both groups said separately on Tuesday (July 9). When completed, the installation will form the largest combined rooftop solar facility in Singapore by a real estate company. Sembcorp…

Traditional silicon-based solar cells have an absolute limit for overall efficiency — in principle, a single photon of light should only be able to loosen a single electron, even if that photon is carrying double the energy required to do so. Now, however, researchers have presented a new way to get high-energy photons striking silicon…

Los Angeles Power and Water officials have struck a deal on the largest and cheapest solar + battery-storage project in the world, at prices that leave fossil fuels in the dust and may relegate nuclear power to the dustbin. Later this month the LA Board of Water and Power Commissioners is expected to approve a…

California set two renewable energy records last week: the most solar power ever flowing on the state’s main electric grid, and the most solar power ever taken offline because it wasn’t needed. There’s no contradiction: As California utilities buy more and more solar power as part of the state’s quest to confront climate change, supply…
