Nuclear is a viable alternative.
Sure nuclear powered car are literally impossible, but nuclear power is one of the cleanest ones. Literally, despite nuclear waste and the fact it's radioactive for 20,000 years, it's one of the cleanest.
Compared to an oil power plant, the amount of actual pollution, beside water vapor, is not even 30% of what an oil power plant generates.
They are a great source. Not the cheapest, but they pay for themselves fast. So, Nuclear is always an option.
However, I'm hoping we stop having oil leaks, because oil in the ocean is useless to us. And not healthy.
Also, Oil in Colorado is what, about twice what we need? All of Colorado is basically covered in shale oil.
And with the price of oil, it's almost cost effective for it.
What we need is for me to become President.
