Now you have confused me.  Earlier today you stated Hydroelectric is not dependent on extracting minerals and does not produce by-products that cannot be returned to the environment without special handling. So you included environmental criteria other than just whether it is replenished. That is why I added the section Definition of renewable.  I suspect that most people actually think of environmental impacts when they say renewable. If so, then it should be added to the definition.  00:19, 2005 Feb 1 (UTC)
