Given that the Gulf has been the nation’s energy sacrifice zone for decades, GRN has a more-than-passing interest in the ongoing debate about expanding drilling, especially as currently framed by the GOP contenders, as a method of decreasing the price you pay at the pump.Because of that interest, I’m going to be representing GRN on the “Think Tank” this afternoon on NOLA’s WWL radio. Tune in around noon for the beginning of the discussion, I show up around 12:35. I think if I can convey the information from the handy Washington Post animation below, I’ll do alright. Aaron Viles is GRN’s deputy director. You can follow him on twitter here.
