Preliminary Monthly Electric Generator Inventory Wind generators accounted for 8% of the operating electric generating capacity in the United States in 2016, more than any other renewable technology, including hydroelectricity . Wind turbines have contributed more than one-third of the nearly 200 gigawatts (GW) of utility-scale electricity generating capacity added since 2007. The increase in wind development in the United States over the past decade reflects a combination of improved wind turbine technology, increased access to transmission capacity, state-level renewable portfolio standards, and federal production tax credits and grants. More than half of U.S. wind capacity is located in five states: Texas, Iowa, Oklahoma, California, and Kansas. In three states—Iowa, Kansas, and Oklahoma—wind makes up at least 25% of in-state utility-scale generating capacity. Several states with the highest wind capacity are located in the Midwest, a region with favorable wind resources . As of […]
