In our country, carbon dioxide (a key greenhouse gas that cause climate change) comes mostly from electricity generation which is based on coal. Coal is a non-renewable energy source, at some point it will all have been dug out of teh ground, and there will be no more.

However, there are resources we can use which are renewable - they dont get used up. Examples of renewable energy technologies are those that use wind and sunshine to create electricity.

There are a number of websites you can visit to find out more about the different types of renewable energy sources that are available. Here are just a few:

Renewable Energy and Renewable Energy Partnership

Renewable Energy Development

World Watch Institute

There are also local reports which provide an overview of renewable energy potential in South Africa:

Restio Energy

Sustainable Energy Africa (look for the download "smart approach to power" under the "renewable energy and energy efficiency section"
