Just look around you.

Out on the street.

Cars, taxis, trucks, and buses all use gasoline.

And lots of it!

Sometimes there are so many cars that they cause a traffic jam.

Have you ever seen a traffic jam?

That's when a lot of cars are moving very slowly.

And sometimes they are stopped.

But as their motors run, they continue to use gasoline.

And look up.

There's the traffic helicopter reporting on the traffic jam and using a lot of gasoline!

Sometimes while you're waiting to move, you hear a siren.

It might be a fire engine or an ambulance.

How can they get by in an emergency?

It's almost impossible.

So, what can we do?

We can use public transportation.

Lots of people traveling together on a train or a subway can save energy.

People can also form carpools and drive together to work or school.

And how about electricity?

We use a lot of electricity every day.

We use it in our homes to light our rooms and to run our appliances.

And what about elevators and escalators?

All tall buildings have them.

When you walk down the stairs, you save energy.

And when you walk up the stairs, you save even more.

We should turn off the lights when we leave a room and use the stairs to save electricity.

And we should use public transportation and carpools to go places.

We should always be thinking about ways to save energy.
