this be done? Scientists and environmentalists could imagine a whole range of potential solutions, from developing alternative energy sources to expanding nuclear power to simply increasing energy efficiency. STEPHEN H. SCHNEIDER, Stanford University: The first major thing to do is to get efficiency improved. We are not anywhere near as efficient as we could be. We don't all have the best motors, the best light bulbs and the most efficient cars and industrial processes. We're not perfect. And therefore, if climate policy forced us to be more efficient, we actually would be replacing inefficient technologies with more efficient ones that would cost us less money to buy them than the money we're saving in fuels. NARRATOR: A lot of energy is simply wasted. If we made our energy go further, we would need less and therefore emit less greenhouse gas. JONATHAN G. KOOMEY, Lawrence Berkeley Nat'l Laboratory: An important distinction to make in dealing with any of these issues is that there is energy conservation, which is typically defined as deprivation- essentially putting on a sweater, you know, dealing with discomfort in some way. And then there's energy efficiency, using new technologies to do the same thing with less energy. NARRATOR: Many electronic devices leak energy. Televisions are a prime example. When they operate, they draw about 100 watts of power. But even after they are turned off, they may still draw energy. JONATHAN G. KOOMEY: Some of my folks actually went to Circuit City and measured all of the
