I don't have any exact figures but my guess is that the money made by all sources of alternative energy in the whole world for a year is probably about what the oil companies make in a week. You can trace nearly all attempts to distort the science back to oil companies and conservative politicians. It's hard to even discuss the issue with the no-politics rule of ETS. Take away politics and there is no discussion to be had, at all. Virtually no credible scientist endorses the view that anthropogenic warming is a "hoax." It all comes for talk radio and paid flacks.
