The capacity of 75.2GW in the US has tripled since the 25GW at the end of 2008, according to AWEA, and now over 70% of Americans support wind power, it claimed.
AWEA said support is higher in states where wind is more prevalent. In oil-rich Texas, where there is almost 18GW of installed capacity 85% of voters favour the technology.
In Iowa, 35% of power demand is provided by the 6GW of wind capacity. According to AWEA, support there stands at 91%.
Going in to the final few months until the US elections in November, AWEA was keen to point out the support wind enjoys.
"Candidates running for office on both sides of the aisle in this important election year should take note: The more wind farms we build, the stronger support from US voters grows," said AWEA CEO Tom Kiernan.
"Highly favourable poll results in Iowa and Texas are particularly compelling. They show that the more wind power installed, the greater the demand for additional development. That should come as no surprise: farmers, ranchers and communities in states like these have long enjoyed the economic benefits of wind power development," said Wind Energy Foundation executive director John Kostyack.
