In Germany, where the FIT scheme has been in operation for over 15 years, the installation of solar systems, large and small, has been massive! Solar and wind energy has blossomed like daisies in spring. Germany now boasts the largest renewable generation of any nation on earth. Nearly 25% of electricity produced in Germany is from renewable sources. The German FIT has been gradually reduced over its lifetime in increments as small as 2 or 3 percent per year. The costs for energy have gone down in Germany.
