Energy Sources

Although California uses more renewable resources than many other states, much of the state's electricity still comes from nonrenewable sources. Find out how using renewable energy sources to create electricity helps reduce fossil fuel consumption and how it has the potential to have the largest impact on climate change.

Energy Sources

This video segment illustrates a variety of energy sources used to generate electricity, some of which are in use and some of which are under exploration.
