Do they need to be appealing? I think our focus should be on energy generation change (phase out coal, nat gas etc). I don't notice if the electricity running into my home comes from green sources (nuclear, wind, solar) or black (?) sources (coal, nat gas). I guess the 'appealing' part comes from the cost. At this point, it seems like green sources are cheaper, we should be building like crazy (I know that to an extend we are).
Plus the solutions are narrow in scope. For instance, we are led to believe that it will be solved if only we all buy electric cars. It might help for certain areas, but it is far from a complete solution. It comes off as a corporate grift.
