Almost three-quarters of all solar and wind power projects being built globally are in China, says a new report that highlights the country's rapid expansion of renewable energy sources. From a report: China is building 510 gigawatts of utility-scale solar and wind projects, according to data from the Global Energy Monitor, a non-governmental organisation based in San Francisco. That compares with about 689GW under construction globally, GEM said. A rough rule of thumb is that a gigawatt can potentially supply electricity for about 1mn homes. "China is [...] leading the world in global renewable energy build-out," the report said. "It continues to add solar and wind power at a record pace." China's expansion of clean energy sources is important for efforts to fight climate change, given the country's dominant role in global manufacturing.Read more of this story at Slashdot.
