Capture clean energy from the wind and the Sun to produce enough electricity to run the town. Move your wind turbine up and down to keep it in the strongest, fastest winds. Keep your solar panels in the bright sunlight and out of the rain. See if you can light up the whole town. Win the clean energy Platinum Award!

Where does our electricity come from?

Like the town in the game, electricity is mostly the kind of energy we use in our homes. Where does our electricity come from? How much of our electricity comes from clean sources like wind and sunshine?

Most of the electricity that powers our homes in the U.S. is produced in power plants that burn coal or oil. These fuels are burned to heat water and produce steam. The steam turns a windmill-like machine called a turbine. The turbine is part of a machine called a generator, which converts the energy from the rotating turbine into electricity.

The trouble is, burning fuels like coal and oil produces carbon dioxide and other pollutants. Carbon dioxide is a powerful greenhouse gas that adds to global warming.

Can we produce electricity without producing more carbon dioxide and making global warming worse? Yes, we can!

The Best Things are Clean, Free—and Renewable

Earth gets enough energy from the Sun every hour to power every light, appliance, and TV on the planet for a whole year! If we could just capture a tiny part of that energy and convert it to electricity, we would never have to burn another lump of coal.

Also, there's energy to be captured from the wind.

We have the technology! We can make electricity from sunlight and wind without creating any carbon dioxide. We can make clean energy.

To make electricity from sunlight, we use solar panels covered with "photovoltaic cells." These cells are small cookie-sized wafers made of materials like those used in computer chips. You may have seen solar panels on the roofs of some houses helping to make electricity for that family.

To make electricity from the wind, we use wind turbines. They work similarly to the turbines used in fossil-fuel-burning power plants, except these turbines are turned by the wind, not steam from water heated by burning stuff.

How much of the electricity coming to your house was made using clean energy sources like wind and solar power? Ask your parents or a teacher to help you find out.
