I have to say, I was a bit surprised by the title of this article that solar power will be mainstream by 2025. The main problem with solar power is that everyday the sun sets and for a significant portion of the day there is no sun.
Still, the article doesn’t shy away from the problems facing solar power.
As a form of energy, solar power is currently at least four times too expensive and it will only become truly mainstream when its dollar to Watt ratio is comparable to other energy sources.
That pretty much sums it up. This will depend on the investment in research, as well as the increases in the cost of non-renewable sources of energy. The article also mentions things like national, international and multi-national co-operation, but I’m not seeing why this is important.
