With most renewable sources such as wind, solar and hydroelectric, "gross energy" is essentially meaningless in this "Prius vs. Electric Transit" argument, except that efficient extraction of available energy keeps the price of the power obtained down. Taking O'Toole's reasoning to its logical extreme, if wind and solar only captures 10% of the available energy, or a hydroelectric project only captures 25% of the energy available, he'd still report absurdly high BTU's expended. Never mind that in these cases, nature still radiates this energy into Earth's environment--whether humans choose to tap into it or not.
