Solar panels could never provide all the power, but if every roof had solar panels on them, the combined energy produced would certainly help. In the UK, you can get grants for this sort of stuff, including wind turbines, solar water heaters, loft insulation, cavity wall insulation, double glazing..............

solar panels are so innefficient now, it just doesn't make sense. I have read that at todays effienciency, it would take nearly 20 years to payoff the initial investment of adding the panels. IIRC, the effiencieny of solar panels is around 2-5%, which is abysmal. One day, yes. Today, it is just too cost prohibitive (even with the government helping),
