Onshore wind is the largest and cheapest source of renewable power in the U.S. today, but solar is catching up quickly. No one is more aware of that urgent reality than the wind industry itself.

Renewables markets long dominated by wind, including Texas, are set for a wave of solar projects over the next few years. Many of the country’s largest wind developers are amassing in-house solar teams.

Amid these changes, the American Wind Energy Association (AWEA) trade group announced Tuesday that its flagship annual Windpower conference and exhibition will expand to include solar and storage, starting next year in Denver.

“We actually hear from many of you that you do as much solar business at Windpower as you do wind business,” AWEA CEO Tom Kiernan told the conference, held this year in Houston. “That’s great; we like that.”
