Before 2011 global investment in clean energy (wind, solar, biomass, biofuels etc.) grew rapidly. Then in and around 2011 many governments abandoned renewables subsidies in favor of capacity auctions, and growth in global clean energy investment ceased. Investment in North and South America has not increased since 2007 and in Asia it has not increased since 2015. Clean energy investment in Europe has been declining steadily since 2011, and investment in the UK and Germany is now approaching zero.
