"Unless we shut down the economy, we need fossil fuels. More efficient light bulbs, energy-saving appliances, cars with higher gas mileage may all dampen energy use. But offsetting these savings will be more people (391 million vs. 305 million), more households (147 million vs. 113 million), more vehicles (297 million vs. 231 million) and a bigger economy (almost double in size).
Although wind, solar and biomass are assumed to grow as much as 10 times faster than overall energy use, they provide only 11 percent of supply in 2035, up from 5 percent in 2008."
Robert J. Samuelson, Washington Post, June 21, 2010
