The world invested more in solar power than coal, gas and nuclear combined last year, a UN report finds. China was by far the world’s largest investor in renewable energy in 2017, accounting for nearly half of the new infrastructure commissioned, according to the report from the UN Environment Programme (UNEP). The report also shows that solar power accounted for more than a third of all electricity generated from energy sources that came online in 2017, a larger share than any other new source, the New York Times reports. On top of this, solar power is becoming more affordable, the report shows, with the cost of electricity from large-scale solar projects dropping 72% in the last nine years. However, fossil fuels still dominate existing capacity, Reuters reports. Solar, wind, biomass and other renewables generated 12.1% of world electricity in 2017, up from 5.2% a decade earlier, the report shows. The findings were also covered by New Scientist, The Conversation and Carbon Brief.
