We can't all expect to agree on everything, but I'm confused about why there is so much promotion of a movie in which a review describes his treatment of alternative energy as including --
brisk dismissals of every form of alternative energy ("Ethanol is an absolute joke -- it takes more energy to make ethanol than you can make burning it") http://latimesblogs.latimes.com/the_big_picture/20...
Can one not see why this is problematic?
The response that "well, alternatives can't solve the problems so ignore them" isn't helpful -- to bash alternatives as basically something some hobbyists are tinkering with sets them up for the same swamp that is happening with the hoax claims about global warming being man-made.
What should have happened is both -- the realities of peak oil and the advocacy of alternative energy, regardless of the doomsday scenario and inevitable world oil wars.
It's too bad that Roger Ebert repeats what the real role of alternatives can be and what we can expect without any type of consultation into other views. Not everyone agrees that we should dismiss them all and try to represent them all with a reference to ethanol.
