U.S. green energy companies face a somewhat chaotic environment at the state level, with efforts underway in 16 states to weaken renewable energy mandates that have been key support mechanisms for solar and wind power. At the same time, 18 states have moved to strengthen those mandates.State mandating of various green technologies doesn't make things easier. It's made it harder. It adds a level of complexity to the market that should never have been there to begin with.
