I think we are a good 80-100+ years out for solar economic mass viability and infrastructure.
With the price of oil extraction going up (a lot), all the Middle East mess, OPEC collapsing for all intents and purposes, and banking monkeys playing games with the supply chain. I think the market is going to force us to innovate eventually. NG is the most obvious to me.
Hydrogen maybe further down the road, but I think solar is going to play a large part too. Obviously this is way way down the road. Conjecture and speculation.
