Energy: Friend or Enemy?
Modern life would be inconceivable without the friendly side of energy.. in recent decades, energy has also become an enemy. Presidents have lamented our “addiction to oil,” we have gone to war to protect oil fields from hostile powers, and air pollution from fossil fuels kills tens of thousands of people every year... most worrisome, the accumulation of greenhouse gases threatens to change the earth’s climate in ways that are unpredictable and dangerous.
