In the countries that actively pursue renewables, they take a good share of the energy mix. Germany went from 6% of renewable electricity (nearly all hydropower) in 1990 to 21% in 2011 and about 24% now, and from 3% of overall energy mix (including heating, fuels, etc., not just electricity) in 1990 to 12% now. And current rates of adoption is at least 2% per year for electricity and 1% for overall mix. That's a big deal. Most renewables have already worked themselves out to be competitive.
