Today, we can burn garbage in special plants and use its heat energy to make steam to heat buildings or to generate electricity. This may sound amazing, but it is really nothing new. More than half of electric power companies already burn another type of solid material to make electricity.

GARBAGE energy


It takes 2,000 pounds of garbage to equal the heat energy in 500 pounds of coal.

That material is coal. Coal is a mineral that was formed from the remains of plants that died millions of years ago. Power companies use the heat energy in coal to make electricity.

Garbage does not contain as much heat energy as coal, though. It takes one ton (2,000 pounds) of garbage to equal the heat energy in 500 pounds of coal

Waste-to-energy plants work very much like coal-fired power plants. The difference is the fuel. Waste-to-energy plants use garbage—not coal—to fire an industrial boiler. The same steps are used to make electricity in a waste-to-energy plant as in a coal-fired power plant:

1. The fuel is burned, releasing heat.
2. The heat turns water into steam.
3. The high-pressure steam turns the blades of a turbine generator to produce electricity.
4. A utility company sends the electricity along power lines to homes, schools, and businesses.
