Forget alternative energies in the short term: we need to save, save, save

Forget alternative energies: in the short term the only feasible solution to reducing greenhouse gas emissions and petroleum dependencies is energy efficiency. There is much to be gained, especially in the U.S., where energy consumption per person has risen above that of any other country in the world. Professor Jim Sweeney directs the new Precourt Institute for Energy Efficiency on the Stanford University campus. Energy efficiency measures can reduce our consumption significantly whilst not hurting our economy nor lifestyle: there is no excuse not to go this way.
