I'm looking for a comparison I can make between "traditional" energy sources and solar energy. This is remarkably difficult to find.
I would to have data on energy cost by source over time (in the years, i.e. 20 yeras would be great).
Ideally, I'd like to show how much solar energy has to come down in price before it is cheaper than, say, gas and the rate at which this has been currently happening.
Any advice would be appreciated.
