Look at the gulf oil spill, we drilled a hole to the oil and it came up on its own without the need for pumps. Oil wants to come up to the surface (it happens naturally) we simply give it the path of least resistance.
@Oberon: I don't believe in renewable energy. There is no such thing. Any source of energy requires just as much energy to create as it generates. (To test: Get a plumb bob, hold string in one hand and and pull the weight to the 3 O'clock position with the other, release weight and it will never exceeded the 3/9 O'clock position) This "Renewable" energy is just feeding off of long term decay of a system. The sun will die and Solar will stop working, the Earth will stop spinning and the winds and tides will stop (no turbines), Uranium will decay to lead and nuclear will stop working. Eventuality all heat will die from the universe and all that's left will be the cockroaches.
Unless you are tapping Zero Point energy and that's not even a certainty.
