Science News Online published an article this month on the many promising recent and ongoing developments in biofuels.
Biofuels, ethanol in particular, have been embroiled in debates surrounding their net energy return on investment (EROI) and their supposed limited potential due to the large amounts of (potentially food-producing) land needed to grow them. Well, I've been putting my two-cents in on various debates in the blogosphere for a few months now and it seems that some of the points I was making are starting to hit the mainstream. New developments in cellulosic biorefining, biodiesel from algae, and thermochemical processes completely alter the former terms of this debate giving rise to entirely new (and much better) EROI and yield per acre.
I encourage you to read the excellent post by Jim over on The Energy Blog for a great summary of these developments. I won't waste my time duplicating his effort here but merely point you his way
