>>60574365EVs have a lot more development potential than ICEVs. In 5-10 years, EVs will probably be better than ICEVs in every way. EVs are widely thought to be the future of road transportation.
Solar and wind have the lowest LCOE already, and they're expected to get cheaper still. Solar and wind are intermittent, but that's not that much of a problem for the US because of cheap natural gas for load balancing. In the future, cheaper batteries will help solve the intermittency problem. So solar and wind could be super cheap sources of energy. Unlike gas, they will never run out. So it's a game you want to be in. When the Permian eventually starts to run out of tier one prospects, you don't want the US to have to go hat in hand begging China to sell you the means to generate electricity and hydrogen feedstock in a price-competitive manner.
Nuclear is also important. China for example has a well developed nuclear industry and can build nuclear reactors for 2.5 $/W, which I think is quite competitive with CCGT plants when you consider fuel costs and the fact that a reactor lasts for 60-80 years. And it's a strategically important export market; there are lots of countries that want to buy nuclear reactors.
