It is my analysis that intermittent energy will not be economically viable (sans subsidies) until storage is sub 100 a kilowatt hour installed. Currently automotive storage is at 137 dollars a kilowatt hour at pack level, but solar plus storage here in Florida is running 800 dollars a kilowatt hour installed. So, a ways to go. Also, an effective machine controlled energy arbitrage system at the kilowatt hour level will be required. Short of this intermittent energy is not going to replace the traditional systems.
In the short term, we can increase fracking supplies quickly in Eagle Ford shale and in North Dakota. We should have enough pipelines to move the oil now. Unfortunately we do not have Keystone XL, but the lifting of sanctions on Venezuela could help, but don’t be surprised if Venezuela is slow to deliver. For one the infrastructure is probably in disrepair and they will like to make the USA twist in the wind for a while.
