We've got the technology. We've got even better technology than we had when Jacobson and Delucchi wrote their 2009 paper.
Solar panel prices are down a huge percent in cost from when they crunched their numbers. Prices are down 42% this year and 70% over the last ~2 years.
Oil prices are up and rising.
I'd say that we're very close to point where the annual costs of powering our cars and homes with wind, water, solar and hydrogen will be less than what using conventional fuels costs today.
Powering your EV with $0.08/kWh electricity will cost you the equivalent of $1.40/gallon gas in a 50MPG ICEV.
Coal costs us a fortune in hidden costs. Oil is costing us a fortune in military and "homeland security" spending.
I'd say we're already past the point where renewables are cheaper.
