What is energy?

 

Energy is the ability to do work (see Figure 1).

 

Our energy comes from natural resources, which are either renewable, sustainable, or non-renewable (see Figure 2).

Renewable Energy

 

Renewable energy sources offer a cleaner alternative to fossil fuels. Renewable energy sources are widely available, and will be for the foreseeable future. However, this energy supply can be unreliable and the quantities are relatively small and hard to store. See Figure 5 and 6.
