Does it really need to be profitable on it’s own though? Renewable energy has a lot less external costs, i.e. negative effects such as global warming, pollution, etc. On a national or global scale, these costs should be accounted for in any study comparing economical competitiveness. Just looking at the balance sheets of energy companies and their costs vs. income is a bit short-sighted.
