can further reduce power output, and the need for cleaning . Projected changes in wind and solar potential are uncertain; the trends vary by region and season . In an RCP8.5 scenario, Wild et al.  conservatively calculate a global reduction of 1% per decade between 2005 and 2049 for future solar power production changes due to changing solar resources as a result of global warming and decreasing all-sky radiation over the coming decades. However, positive trends are projected in large parts of Europe, the south-east of North America and the south-east of China.
