You won’t see this car on the road, at least not yet. It’s a concept car that was developed by a major automaker. Instead of burning gasoline, it runs on hydrogen gas. Using hydrogen for fuel doesn’t produce pollution, and it doesn’t depend on nonrenewable fossil fuels. New technologies like this car may one day help solve our energy resource problems. But even without new technologies such as this, there are many ways we can help solve the problems right now.

Conserving Energy

Everyone can reduce their use of energy resources and the pollution the resources cause by conserving energy. Conservation means saving resources by using them more efficiently, using less of them, or not using them at all. You can read below about some of the ways you can conserve energy on the road and in the home. You can find more energy-saving tips at this URL: http://www.partselect.ca/resources/Home-Energy-Saving-Tips.aspx

Conserving Energy in Transportation

Much of the energy used in the U.S. is used for transportation. You can conserve transportation energy in several ways. For example, you can:

  • plan ahead to avoid unnecessary trips.
  • take public transit such as subways (see Figure below ) instead of driving.
  • drive an energy-efficient vehicle when driving is the only way to get there.

Q: What are some other ways you could save energy in transportation?

A: You could carpool to save transportation energy. Even if you carpool with just one other person, that’s one less vehicle on the road. For short trips, you could ride a bike or walk to you destination. The extra exercise is another benefit of using your own muscle power to get where you need to go.

Conserving Energy at Home

Many people waste energy at home, so a lot of energy can be saved there as well. What can you do to conserve energy? You can:

  • turn off lights and unplug appliances and other electrical devices when not in use.
  • use energy-efficient light bulbs and appliances.
  • turn the thermostat down in winter and up in summer.

At the following URL, play the energy-saving game to see how much energy you can save by replacing incandescent light bulbs with energy-efficient compact fluorescent light bulbs.

Q: How can you tell which light bulbs and appliances use less energy?

A: One way is to look for this ENERGY STAR® logo:

Summary

  • Conservation means saving resources by using them more efficiently, using less of them, or not using them at all.
  • Everyone can reduce their use of energy resources and the pollution the resources cause by taking steps to conserve energy.
  • There are several simple ways to conserve energy in transportation and at home.

Vocabulary

  • conservation : Saving resources by using them more efficiently or not using them at all.

Practice

At the following URLs, find more ways that young people can conserve energy. Then create a poster to show other people your age how they can save energy. Your poster should demonstrate at least four practical ways young people can use less energy in their daily lives.

Review

  1. What is energy conservation?
  2. Describe one practical way that you could save transportation energy in your own life.
  3. Draw a sketch of a house in which energy is being wasted. Then explain how energy could be conserved instead.
