For more than a decade, a fierce debate about peak oil has been raging between those who think a peak in global oil production is at hand and those who think the world is not close to running out of oil. The debate is moot for two reasons. First, the growing threat of global warming requires deep reductions in national and global oil consumption starting now, peak or no peak. Second, relying on unconventional oil like tar sands and liquid coal to make up a supply shortage, as the oilmen say we must, would be climate catastrophe. More supply is not the answer to either our oil or our climate problem — reducing consumption of oil is. And right now we have two feasible solutions: greatly increase our vehicle fuel economy and find alternative fuel sources that are abundant, low-carbon and affordable.
