The following video has two Lawrence Berkeley National Laboratory (LBNL) researchers, Ryan Wiser and Joachim Seel, presenting their research findings on future wind power costs and cost drivers to the International Energy Agency in September. Also see their article in Nature Energy, which explains the results of a survey of "163 of the world’s foremost wind experts, aimed at better understanding future costs and technology advancement possibilities" for wind power. The bottom line findings are impressive: a median forecast of 24%-30% reductions in wind power costs by 2030 and 35%-41% reductions by 2050; with even greater reductions possible -- possibly more than 50% by 2050 -- in the most optimistic scenario.
