Democrats have voted down a GOP plan to lower Colorado's renewable energy mandates.

A bill to lower the mandates failed 6-5 Monday in a House committee controlled by Democrats. The bill the Republican state Senate last month.

The bill would have cut in half the percentage of renewable energy required of large utilities by 2020, from 30 percent to 15 percent. It would have reduced the renewable energy mandate on rural electricity co-ops from 20 percent to 15 percent by 2020.

Republicans said the renewable energy mandates go too far and burden ratepayers. Democrats said the mandates have created jobs in the renewable-energy sector.
