**Goals:**

Students will learn about Earth's energy sources and how they are being
used. They will also explore how energy is converted and what
alternative energy sources are available when fossil fuels are
exhausted.

**Questions**:

You will be able to answer the following questions at the end of this
presentation:

-   Is there an energy crisis?

-   How much do we have?

-   How fast are we using it?

-   When are we going to run out?
