They are essentially the same thing, or at minimum, result in the same thing. The ROI will rise as the use of oil is relegated to more important things than powering cars. Oil is also used as the basis for the organic molecules in pharmaceuticals for example, which many believe serves a higher and more valuable purpose: Saving lives over Transportation. So, oil will continue to be extracted. Remember, it doesn't take oil to extract oil, it takes energy. The value of oil is more than simply for the production of energy, therefore, as long as uses for oil can be found that are more valuable to consumers than energy, it will continue to be extracted. We will use solar energy or hydro to extract the oil, then package it up into more valuable forms to sell to the public. More valuable that is, than solar power or hydro.
