Actually ethanol my be an answer, but in fuel cells. Already have them in small ones, but it will be a while before they are scaled up.
Another is Nuclear power. Solar panels. All good, but the problem with all of them is it just reduces demand for oil and therefor, reduces price so it is more affordable and cheaper than the alternatives.
So do we do as the Brits and increase taxes on it to reduce demand? That would put more money in the US pocket and less in Iran's and SA.
Has anyone here looked at the numbers?
Can we grow enough ethanol to fuel all the cars in the US?
Basically burning ethanol is using solar power.
I find it hard to believe that we can. It is also seasonal. And last but not least it uses a lot of water.
No, taxing is not the solution.
