The Wall Street Journal yesterday had an excellent article on the technological and economic prospects of biofuels. At today's oil prices, a number of biofuel technologies are competitive with oil.
The article suggests that biofuels could replace about 10 - 20% of US oil needs in the next couple of decades - a modest but still important contribution.
The article is subscirbers-only but luckily for us the Ecological Economics Blog has reprinted some of the really interesting bits.
Your website has a useful information for beginners like me.
