"The only realistic solution is nuclear. And it isn't happening."
Nuclear energy would barely dent consumer consumption of petroleum products. Replacing Arab oil is already happening but at a creeping pace. Coal to oil and ethanol mass production are our immediate hopes to replace Arab oil. Pennysylvania and Colorado both have working plants subsidized by the Feds. Billions are being invested by the private sector in ethanol. Nuclear plants could lower the cost of conversion of coal/ethanol with the rest of spare power feeding major metros. I do not see a "Hydrogen Economy" for at least two decades.
