The Kansas Senate has voted 25-15 to repeal the state's Renewable Portfolio Standards (RPS), which require 20 percent of Kansas power generation to be from renewable sources by 2020.
The requirements were passed in 2009 and have been credited with helping promote wind power development. The vote came after more than an hour of debate.
Opponents of the standards say they pick winners and losers, and wind power growth has outpaced the renewable requirements. They argue that the standards have led to rate increases with more in the future.
