    Solar energy - photovoltaics - to me represent the freedom of the bottom because quantum phenomena are involved. Let the sun excite one atom, and you may harvest one electron.

    In countries with expensive electricity and much sun, solar power stations (photovoltaic) are already profitable, they tell me.
