It's a ploi to instill a sense of urgency amongst the industrial industry to develop alternative fuel sources... They can put heat on the research groups as well as the industrial sites that burn a lot of fossil fuels and contribute to air pollution to move towards cleaner burning alternative fuels or manufactuering methods... This also creates a niche market for corporatations that are at the spear point of creating alternate fuels... The government isn't seperate from our indusrty like a lot of people are taught to believe... Each representative has their own motives and they're all normally pushed by that particular representatives supporters... The reps and congress are just hands of industry... To create an urgency to create alternate fuels sources... creates a market for ethanol and hybrid cars... hm....? who benefits from that??
