'We're in the position of somebody that can't keep the bathtub full because the water keeps running out. Before we buy a bigger water heater, we ought to get a plug.' -- Amory Lovins

Since the 1970s Hunter and Amory Lovins have been the foremost proponents of an energy policy that concentrates on efficiency and the appropriate use of renewable energy sources such as the sun, wind, and water. The Lovinses call this the 'soft path' and in this classic film argue for its practicality as opposed to the 'hard path' which favors increased energy production and the use of coal and nuclear power.
