To be sure, wind and solar have increased dramatically. Since 1990, wind-generated power has grown 26% per year and solar a phenomenal 48%. But the growth has been from almost nothing to slightly more than almost nothing. In 1990, wind produced 0.0038% of the world’s energy; it is now producing 0.29%. Solar-electric power has gone from essentially zero to 0.04%.
