Thousands of miles apart, in vastly disparate environments, the Gulf of Mexico and Alaska's Chukchi Sea have something in common: Both illustrate the increasing futility of an energy policy heavily dependent on oil.
The risks in the Gulf's offshore drilling became brutally apparent in April 2010, when a BP deep-sea well exploded, killing 11 oil rig workers and causing a massive spill of almost 5 million barrels of crude. The disaster led to new regulations for offshore drilling.
In the Chukchi Sea, off Alaska's northwest coast, the challenge is not the depth of the water but the ice upon it. Floating sheets of ice, along with powerful waves, have confounded Royal Dutch Shell's so-far six-year, $5 billion effort to drill offshore. Approaching winter and persistent problems with an oil-containment barge recently forced Shell to postpone its efforts for another year.
The difficulties and risks, both in the Gulf and in the Arctic -- as well as off the east and west U.S. coasts and in shale formations -- were summed up in last Tuesday's Herald-Tribune by Houston Chronicle columnist Loren Steffy: "Quite simply, the easy stuff is gone. All require expensive and time-consuming drilling techniques."
Consequently, claims by candidates or elected officials that America could achieve oil independence if government would only get out of the way are just a lot of hot air.
The U.S. Department of Energy has established that America has only 2 percent of the world's proven oil reserves. Yet, we use 25 percent of the world's supply.
Only the high price of oil (more than $90 a barrel) pushes companies like BP and Shell to attempt to extract it from mile-deep wells or the frigid Arctic seas. Read More
