How Can We Save Energy?

Saving energy means decreasing the amount of energy used while achieving a similar outcome of end use. Using less energy has lots of benefits – you can save money and help the environment. Generating energy requires precious natural resources, for instance coal, oil or gas. Therefore, using less energy helps us to preserve these resources and make them last longer in the future.

The sun warms us and gives us light during the day.

At night, and during the colder months, we need light and warmth from other sources…

Since early times, people have lit fires ….…. but fires make smoke, and are not convenient in modern homes.

Clue 2Clue 1

The electricity which we use is mostly made by burning coal or gas in power stations.

And our central heating boilers usually burn gas or oil.

The trouble is, this makes lots of ‘greenhouse’ gases which scientists believe are warming up the Earth and the air around it.

The ice in the arctic is melting, and the polar bears’ habitat is shrinking.

In some hot countries, there is less rain, and rivers are drying up.

In some places the land is becoming so dry that the farmers can no longer grow crops.

So what can YOU do to stop global warming?

You can turn off the lights when you don’t need them!

Suggest that the grown ups who do the shopping buy energy saving light bulbs.

and set the clock so that it is on for less time.

Remind everyone to keep the doors and windows shut when the heating is on, to keep the warmth in.

You wear clothes to keep in your body heat.

Find out if your home is insulated to keep the warmth from escaping through the roof.

That way it will take less energy to bring it to the boil.

If you can see a light like this when the TV is off, it is using almost as much energy as if it was on!
