The Environmental Defense Fund really puts out good science. They are truly non partisan and report the facts as they are known. I just read this posting called "Getting Natural Gas Right" and I was both intrigued and encouraged. The conclusion is simple (and those who take ideological positions on science will not like it): If large amounts of methane are released into the atmosphere due to leakage, the use of Natural Gas will be worse, not better, than what we are doing today.
However, there is great news. If prudent measures are taken to ensure the proper drilling, transportation, storage and combustion then natural gas becomes a fantastic fuel to help us move to a low carbon future.
I like science.
