Im amazed at the difference a few years can make. How many of you remember that about 20 years ago the doomsayers were talking about how we were at the beginning of the end of the hydrocarbon based economy? There was great fear that we wouldnt have enough oil to do all the things that we were used to doing. Then came a push to find non-petroleum ways to fuel our cars and to boost fuel economy. Governments leaped into the fray to legislate the new era of reduced expectations. Some of the benefits of all these activities were ethanol in our gasoline, subsidies for hybrid vehicles, mandated hikes in corporate average fuel economy standards, grants for solar and wind power projects, and so on.
