The internal combustion engine isn't going away overnight. EVs are wonderful and there're all sorts of situations where they're clearly superior, but there're also a very significant number of situations where they're not even remotely theoretically capable of replacing their internal combustion counterparts -- at least, not for quite some time. So the question is whether 'tis better to pump petroleum out of the ground to burn in those engines, or to use the CO2 that's going to come out of the electricity plants (whether we want it to or not) to burn in those engines. That's the thing about hydrocarbon fuels. They're both energy sources and energy storage systems. And our civilization isn't going to function without them, at least not for quite some time. However, they don't _have_ to be a package deal. We can keep using hydrocarbons for energy storage for a while even while we get the energy from somewhere other than out of the ground. It's not the perfect solution...but the perfect can't be the enemy of the good. Again, that's the choice. The electricity stations are going to pump out CO2, and the trucks are going to burn diesel, at least for quite some time. We can either let the CO2 go to waste and pump more oil from the ground to burn in the diesel engines, or we can use the carbon from the electricity stations to burn in the diesel engines and leave the oil in the ground. b& -------------- next part -------------- A non-text attachment was scrubbed...
