|I keep on hearing that wind and solar energy are not efficient because it costs more money and energy as the medium can ever supply.|
I just figured out the sceptics are awfully wrong because they are awfully optimistic. Sure the source of green energy will take for ever to win back it's own investment. But this is actually the huge advantage. We can all imagine what energy will finally cost on this planet. One thing is certain, it will run out one day. How profitable are those solar panels then? It's not like we could afford to make em if we have no resources. I bet those things are priceless in 20 years from now. A winner investment.
Think about it... Can a solar panel be to expensive after we run out of energy? Or is it to expensive before?
