I interpreted his "liquidate them" comment to mean basically forcing the companies to break apart and sell everything off, (perhaps seizing all their assets judicially). So, presumably, we'd still have a bunch of oil companies, but they wouldn't be the ones we have now, or nearly as powerful, and their current owners would all be up a creek.
Oh come on. Enough sunlight hits the earth in an hour to power worldwide consumption for a year.
It takes an infinitesimal amount of land if you were going to use solar alone [1]. There is enough wind power potential in the US midwest, from North Dakota to Texas, to power the entire US 4x over [2]. There's enough generation capacity to move 77% of light vehicles in the US over to electric immediately. There's plenty of energy to go around.
Fun fact: The latest budget bill that passed at the end of 2015 had one of the largest subsidies (ITC production tax credit) for solar and wind generation installation ever.
Yes. They've known about their products causing climate change for decades. They should be liquidated.

Some, not all.

Only the ones that are "too big to fail" or those engaged in illegal activities.
