When the Soviet Union chucked Sputnik into space in 1957, it galvanized America to come from behind and win the space race. The federal government opened its checkbook to finance an array of projects. Students shifted to new subjects like astronautical engineering and Russian studies to help the United States understand and eclipse the Soviet Union. The moon shot inspired a patriotic nation and produced useful commercial technologies along the way. The space race was expensive, but it worked.

Thomas L. Friedman’s latest book is a plea for a new Sputnik moment. His breezy tour of America’s energy policy documents a nation that has become dangerously dependent on fossil fuels. The bulging bank accounts of oil exporters like Russia, Iran and Venezuela give them the swagger and ability to cause lots of mischief.
