Three stories:
1) Thin solar panels allow all sorts of new applications such as clothing, car doors and signage to act as bases for solar panels which would dramatically reduce the need for external power - reducing reliance on fossil fuels.
2) Mobile solar panels for any application - no need for the mains.
3) Electric cars run by the sun. No need for petrol - ever.
All three sound pretty good to me. If we can get better batteries we may even reduce the need for fossil fuels entirely. May not be a bad thing at all.
