1. All About Energy
The energy we use every day comes from a variety of sources. Fossil fuels, such as oil and coal, are nonrenewable. These energy sources can only be used once and cannot be replaced. Other energy sources, such as solar and wind power energy, are powered by sources that are naturally replaced and are considered limitless. These are called renewable energy sources.
