The report Global Trends in Renewable Energy Investment 2018, published by UN Environment, the Frankfurt School-UNEP Collaborating Centre, and Bloomberg New Energy Finance, finds that falling costs for solar electricity, and to some extent wind power, is continuing to drive deployment. Last year was the eighth in a row in which global investment in renewables exceeded $200 billion – and since 2004, the world has invested $2.9 trillion in these green energy sources. Overall, China was by far the world’s largest investing country in renewables, at a record $126.6 billion, up 31 per cent on 2016.
Solar energy dominated global investment in new power generation like never before in 2017. The world installed a record 98 gigawatts of new solar capacity, far more than the net additions of any other technology – renewable, fossil fuel or nuclear and solar power attracted far more investment, at $160.8 billion, up 18 per cent, than any other technology.
In total $279.8 billion was invested in renewables excluding large hydro and a record 157 gigawatts of renewable power were commissioned last year, up from 143 gigawatts in 2016 and far out-stripping the net 70 gigawatts of fossil-fuel generating capacity added (after adjusting for the closure of some existing plants) over the same period.
