From industry advocacy group, Vote, comes this information to review concerning Proposition 7 on the California ballot:

Proposition 7 is a California ballot initiative that would dramatically increase the state’s renewable energy requirement, to 50% renewable by 2025. Yet most environmental groups and almost all renewable energy companies and trade associations oppose it. Why?

The problem is not with the goal. We urgently need to increase our usage of renewable energy to 50%--and more. The problem is that the initiative is unlikely to deliver the desired result. Most of the opposition comes from a belief that Proposition 7 is so flawed that it will make the task of growing renewable energy markets harder, not easier.

Different groups have found many elements of the initiative problematic.
