So, again, you don't bite the hand that feeds you! For all you know it WILL be the fossil fuel researchers and producers, who, will discover the next sustainable fuel/energy source. Your position with regards to subsidies is a political one, not an innovative one. That was my point in my original response to you. What you call "green" may not be the answer- the answer may be another source of fuel- or a better way to deal with shale and sand.
What you seem to missing missing is that I am not advocating removing the subsidies, only pointing out that they deflect from the true cost of fossil fuel use, and that were green fuels to receive equivilent funding, they would be competitive.
