Non-hydro renewable energy would comprise 3 percent of global energy by 2020. There would be 30 gigawatts of wind power worldwide by 2010, but the estimate was off by a factor of 7. Europe would have 50 gigawatts of wind by 2010 and boosted that estimate to 75 two years later. China would have 2 gigwatts of wind power installed by 2010.
All those numbers were reached by the year of 2010.
