Energy Sources

 

Have you ever wondered how electricity is produced?

Nearly all the electricity produced in the United States depends on a technology called magnetic induction. Magnetic induction creates electricity by using copper wire, a turbine, powerful magnets, and an energy source to turn the turbine.

What energy sources do we use to "turn the turbine"?

We use non-renewable energy sources like coal, nuclear power, and natural gas. We also rely on renewable energy sources such as wind, water, sunshine, heat from the earth’s core, gases released by decomposing garbage, and other forms of biomass energy.

In addition, there are many intelligent people trying to figure out new, cleaner, cheaper, and safer ways to generate electricity. Some ideas in the works include oil shale, CNG, fusion, hydrogen fuel cells, and more.
