In many countries today, a lot is being said about harnessing renewable energy technologies – particularly in light of the rising oil prices. But what is renewable energy? And what are some of the common renewable energy technologies in use?

Renewable energy is power which has been generated from renewable resources – in other words, it does not “run out” or eventually become depleted. It can be continuously re-created.

It’s not just the prices of oil that has people searching for clean and renewable energy sources. Global warming concerns, and international pollution problems, have triggered this concern as well. Governments around the world have begun to support research on improving the renewable energy technologies.
