I've been linking to and telling you lately about all the different technologies that have been in the works to create energy for sources other than oil, coal, or natural gas - or about additional deposits of oil, coal, and natural gas. One very interesting form of renewable energy comes from the oceans waves, their are a number of ways to take advantage of the oceans waves to produce electricity, the link above takes you to an article about a device that can power 2,000 homes and resembles a sea snake.
While things may look gloomy, remember that a free society will always solve their problems and in ways most of us never even thought of or thought possible. The world may seem likes it on the verge of a global depression - it isn't. It is on the verge of an explosion of technological and biological breakthroughs unlike anything this earth has ever witnessed. It won't happen tomorrow, but the coming decades will knock your socks off.
