OIL SPILL - A few technical details

Today I spoke with a friend who knows somebody in the oil industry who has exposure to the undersea drilling business. My friend said that it was likely that the reason why there was a problem with the Deepwater Horizon is because this was such a deep well, that there was a tremendous amount of pressure, more than anticipated. The deeper the well, the more pressure there is. Basically, drilling this deep is something new, and people still don't know everything about how to do it properly.

As more and more older wells run dry, more and more new wells will need to be dug. These newer wells will need to be drilled deeper and deeper to get at the oil which is still present in the earth. Much of these new wells will need to be undersea wells.

I am open to suggestions on using less energy, as well as creating new sources of energy which will be less hazardous to the environment.
