Either way, the dependence on oil needs to stop, but of course the oil industry is too greedy for that to happen, considering GM tried in the 90s with a perfectly viable electric car, of which hundreds or thousands now sit derelict in a lot somewhere because of the greed of the oil industry. Sad that over 10 years later we're finally seeing electric cars and other means of alternative fuels really taking off.
I agree that we have to reduce our dependence on oil, but the better way is reduce the number of oil power plants, a large amount of oil is consumed that way.
I also never said that you said that replacing it fully was the answer, but renewable doesnt help if there isnt enough.
using the math from here: http://auto.howstuffworks.com/fuel-e...uestion707.htm
26.1 pounds of corn produces 1 gallon of ethanol. so a normal 12,000 mile a year car would require 3 acres of corn at 20mpg on ethanol
there are about 150 million cars in the US, so 450 million acres would be needed for corn production, there are currently 375 million acres used for crops now, so if we grew nothing but corn we would still not have enough for all of the cars, not even counting trucks.
