Walter Youngquist, PhD Biography

Emeritus Chair of the Department of Geology at the University of Oregon at Portland
Con to the question "Can Alternative Energy Effectively Replace Fossil Fuels?"

“Ethanol is a net energy loss – it takes 70 percent more energy to produce than is obtained from the product itself. Other biomass resources show, at best, very low net energy recovery…

The two most popularly suggested energy alternatives, wind and solar, suffer because they’re undependable, intermittent sources of energy, and the end product is electricity. We have no way to store large amounts of electricity for use when wind and sunshine are not with us. Geothermal and tidal energy are insignificant energy sources in total but can be locally important. Nuclear energy can be a large power source if the safety aspects can be guaranteed (and this may be possible) — but again, the end product is electricity. There is no battery pack even remotely in sight that would supply the energy needed to effectively power bulldozers, heavy agricultural equipment such as tractors and combines, or 18-wheelers hauling freight cross-country.

Can electricity be used to obtain hydrogen as a fuel from water? It can, but hydrogen is difficult to store and dangerous to handle. And there is no energy system now visualized to replace kerosene jet fuel, which propels a Boeing 747 about 600 miles an hour nonstop on the 14-hour trip from New York to Capetown (currently the longest plane flight). We continue to seek the holy grail of energy – fusion – but containing the heat of the sun at 10 million degrees Centigrade is still only a far-off hope.”
