Bill Gates: We should tax oil and gas, no matter when it comes from.

"We should tax oil and gas, no matter when it comes from. The idea that if we don't drill it here if it's untaxed, it's gonna get drilled somewhere. The key thing is that you've got to take this externality which is the CO2 emission and make it unattractive and as you do that tax, then you have the alternative things come in, which in the case of passenger cars, getting down to the low end is hard but we need to get there."
