In 10 years, without increasing our energy sources from nuclear power and without extracting the oil and gas resources within our nation’s boundaries and the continental shelf, Al Gore proposes that wind and sun alone will solve our energy problems. Can anyone subscribe to his theory? Natural gas and oil will no longer heat our homes or power our vehicles. Coal, oil and nuclear will no longer supply the electrical power to our homes, industries and communities. Our carbon footprint will be zero. Wind, sun, a smattering of tide and hydro power will be our sole renewable energy sources. While not clear on this issue, I suppose Al Gore sees us all zipping around town or out on the highway with little electric cars with enormous batteries. All of us have seen the disastrous results of such past theories, such as the headlong plunge into ethanol from corn to replace a portion of our gasoline supply. Ethanol production required massive taxpayer subsidies, reduced car mileage, polluted the air and increased the cost of gasoline per gallon to the consumer -- all with the unintended consequences of raising food prices throughout the world. Al Gore’s proposals would have to work hard to produce worse consequences but certainly have that potential.
