The Arizona Corporation Commission this week approved Mohave Electric Cooperative's request to count the electricity from a waste-to-energy facility toward its renewable-energy goals. The commission requires utilities to get 15 percent of their electricity from renewable sources by 2025 and to additionally reduce their power demand by 22 percent by 2020 through conservation. Mohave, a tiny, non-profit distribution utility in northwestern Arizona, asked for the waiver to make electricity from trash because that type of unit was not initially included in the Commission's program.  The commission voted 3-2 in favor of Mohave's request.
