Below are three examples of using energy from natural resources. Select the use of energy that did not add to air pollution.
A torch burned natural gas, making a flame hot enough to melt glass. The engine on a container ship burned fuel made from petroleum oil. Wind moved a hang glider through the air.
Humans have invented many ways to use energy from natural resources. Some of these uses of energy add to air pollution, and others do not.
Hint: Burning a material such as wood, oil, or coal releases chemicals that add to air pollution.
Humans have invented many ways to use natural resources. We use energy from natural resources in our daily activities, including cooking food, moving objects, and powering machines.
Some ways of using natural resources for energy add to air pollution, and others do not.
Wood, oil, and coal are examples of natural resources that are fuels. Burning a fuel provides energy. But it also releases chemicals that can be harmful to our health and to the environment. These chemicals add to air pollution.
Sunlight, wind, and water are natural resources that can provide energy. Using energy from the Sun, wind, or water does not burn material. These uses of energy do not release chemicals that add to air pollution.
