Some energy fundamentals
Don Lancaster's Guru's Lair News newsfeed turned up his now-several-years-old article called Some Energy Fundamentals today. It might be worth your while to read, if you figure the transition to the replacement for gasoline is going to be easy. While I haven't checked all his calculations and statements, it seems more scientifically based (or engineering-based) and less alarmist than many such essays. It doesn't paint a rosy picture, though. I'll be curious regarding the critiques any of you might provide.
