As oil becomes more scarce, its price will rise sharply. A large increase in the price of oil would have significant negative effects on the global economy. It can be argued that money spent to reduce our dependence on oil is only "giving up" in the same sense that saving money is giving up the ability to spend it. The opportunity cost of not pursuing alternatives is _much_ higher in the long run.

Do you actually believe that alternative energy is not a good investment, or were you attempting to rationalize why one might be opposed?
