The U.S. wind industry has its work cut out for it. That was the message put forth today at the start of Windpower 2014, an annual event taking place in Las Vegas this week. Tom Kiernan, CEO of the American Wind Energy Association (AWEA) opened the show with a keynote speech that reviewed steps that the industry had taken over the past year in order to reach its goals. In 2013, the industry set goals of doubling the amount of installed wind power capacity by 2020 and increasing it to 20 percent of the U.S. energy mix by 2030. Wind power currently makes up about 4 percent of the U.S. energy mix.
