Energy is everywhere. We use energy every day.
Electricity is a form of energy and this is what powers the TV, hairdryer, phone, fridge, electric toothbrush and more! Our growing need for energy is one of the problems facing the world today, because producing electricity also produces pollution.
Here are some simple ways to make a big difference when using electricity.
On or off? Leaving televisions and computers on with the little red light showing still uses electricity, even though they might look like they're turned off. To stop this you can turn them off.
Lights out! Turning lights off when you're not in the room can save a lot of energy.
Fridge door closed. The fridge is an important part of the kitchen, because it keeps food fresh, cool and healthy! But it takes a lot of energy to keep cool, so try not to leave the fridge door open or put hot things inside.
Use the sun's energy. An increasing number of people are fitting solar panels（太阳能电池板） to their houses. They create electricity from sun-light, which can then be used to power our homes. Solar heating panels make hot water, reducing the need for electricity or gas.
