currently the vast majority of power comes from fossile sources (coal, gas, petrol). just imagine what amounts of gasoline are used every day for transportation. there's no way in the near future, that we're gonna replace this amount of energy with solar energy. no way. we either switch to a nuclear powered, hydrogen based economy (once we run out of gasoline) or we say goodbye to mobility. and by the way, this isnt a really a question of price. solar energy is highly dependent on current daylight, we would have to rethink our entire energy distribution, building either much cheaper batteries, to provide a constant level of energy on the grid or create some sort of highly efficient global energy grid. those problems are far from solved. at least not at an affordable rate.
