Maybe I'm the ignorant one but are you conflating gas from oil with natural gas, which actually has been driven to record low prices[1], so much so that utilities have switched from coal to natural gas at such a fast pace that it reduced our greenhouse gas emissions by a considerable amount in 2012[2]? "Prices as high as ever and destroy the environment as a bonus" may be doubly wrong.
