Alcatraz in San Francisco Bay, Calif.

Speaking of island prisons, the United States’ most famous (or is it infamous?) prison is also known for its green practices. It’s now part of the U.S. National Park System, but Alcatraz still must deal with many of the same challenges from its days as a prison. Because everything on the prison-island has to arrive by boat, one reporter explains that Alcatraz is “green by necessity.”

Alcatraz has a water catchment system for garden irrigation. Workers take home dirty dishes to preserve water. A multimillion-dollar stimulus project is under way, and solar panels will provide half of the prison’s electricity by the summer of 2011.
