shouldn't conservation of energy be just as important as finding new sources of electrical mechanical energy? It seems like everyone always talks of finding more energy, but everywhere you look, energy is constantly being wasted.
Take for example the automobile. Everyone is concerned with gas prices and peak oil, so they are looking for alternate fuels to power one of the most inefficient forms of transportation. Moving one person around in a five thousand pound transporter is a horrible foundation for a national transportation network. Instead of focusing on such an automobile centric economy, people should focus more on bringing things to people and improving mass transit.
I have traveled extensively, and I have seen much more efficient means of moving people than the single occupant automobile. The key in these places was that the automobile was not the center of planning.
