Advances in technology, improved economics, and broad political support are making wind power a formidable twenty-first century energy resource. Top-ranking Denmark draws 41% of its electricity from wind; Ireland follows with 28%; the European Union as a whole gets 14% of its power from wind.
America’s wind farms currently produce 6.6% of the nation’s electricity. As a share of total power generation, that may sound relatively modest, but the U.S. ranks second only to China in the quantity of power-generating capacity that comes from wind. Moreover, the U.S. has scarcely begun to tap its vast wind power potential. On land, U.S. wind resources are capable of yielding about nine times the nation’s power needs. Offshore wind – wholly unexploited to date – could meet nearly twice the nation’s electricity demand.
Looking ahead, the Department of Energy has prepared a scenario for 35% wind reliance by 2050. While that level of wind generation sounds like major progress, it may be substantially less than is needed for renewable energy resources to be the primary drivers of a net-zero carbon U.S. economy.
