Energy sources are different ways that are used to make electricity. There is non-renewable and renewable energy. Here are some energy sources:

|| Fossil Fuels || Fossil fuels is not very good because you burn stuff down which creates lots of smoke and it is not good for the earth. || Here are some windmills put together to spin a turbine creating electricity. They are getting the wind from the drafts. || Thermal Energy This a model of what a real life machine that gets the steam from under the ground. || ||
 * Solar Energy || These are some solar panels that are put together to make more electricity.

How do they work?
Thermal energy is when we put water in the ground through tubes and very hot rocks heat up the water which turns the water into steam and the steam turns a turbine creating energy. Fossil fuels are dead animals and plants that get covered in rocks/sand over time. Once the animal or plant gets turned into a solid we pump it up and what we pump is fossil fuels. We use windmills to make wind energy. When the wind hits the windmill the fans spin causing wind turbine spin creating electricity.

Solar Energy!
Our community should use solar energy. Solar energy is energy that is created by the sun. The sun makes electricity because it rays knock out a electron causing the others to go forward making electricity. Photovoltaic cells can convert sunlight directly into electricity. There are advantages and disadvantages to solar energy. Here are some listed below.

Advantages:

 * Does not create any pollution!
 * Photovoltaic cells are easy to install and can be used anywhere.
 * Can provide some or all of a buildings electricity.
 * Can connect to batteries to save electricity.

Disadvantages:

 * Solar pannels can be expensive.
 * Photovotovaltaic cells only work in places where the sun is shining.
 * If the sun does not shine brightly every day batteries are needed to produce power.
