Plenty of time to build a bunch of breeder reactors, if we just get the government (in the hands of the NIMBYs) out of the way.
but it's safe to assume that engines that run on something other than gasoline will not be significant for a good long while. And this irreplaceable gasoline accounts for about 45 percent of all our oil consumption.
What would our situation look like if 100% of our oil went into transportaion? Assume that anything that's stationary and can hook up to the grid is run by coal, hydro, wind or nuclear.
Bringing back the nuclear industry is now a national security issue - something the French and Japanese have understood for a long time.
Did you know we have oil wells all over Ohio, literally in back yards, cow pastures, parks, woods , and every other place you can think of? ditto Pennsylvania, Western New York State, and God knows where else.
Do these tree hugging clymers actually think a Caribou is going to give a tinker's dam about living next to an oil well? Jeesh, this country has been taken over by the stupidly evil or the evilly stupid!
Drill Anwr, dammit. When the first well comes in, we'll meet at my house for some roast spotted owl and throw darts at Barbra Streisand and Diane Feinstein posters.
(BTW, did you ever notice the same people who want to preserve the environment have no qualms about allowing 10 million illegal aliens crowd into the US and have 10 kids apiece. This certainly hasn't helped the environment in Southern California. Without development, how are we supposed to feed, clothe, house, educate, and employ these Third World Border Bounders who are turning many areas into little Third World Hellholes?)
Nearly impossible. Our manufacturing base depends on oil (all machinery does), not to mention plastics.
