Electricity changes people’s life in many ways. Before electricity was widely used, people lived a very simple and hard life. They had no electric lights, so they could only use candles and oil lamps at night. They could not watch TV or use fridges to keep food fresh.
Today, electricity supports almost all modern life. We use lights to brighten rooms, fridges to store food, and heaters to keep warm. Factories depend on electricity to run machines and produce goods. Hospitals use electrical equipment to save people’s lives.

Second, hydropower stations make use of flowing water. They are built on rivers and use water power to turn machines. This kind of electricity is clean and causes no pollution.
Third, solar power stations collect sunlight energy. Solar panels can turn solar energy into electricity directly. It is completely green and renewable.
Fourth, wind power stations use wind power. Wind turbines work on windy days to produce electricity. More countries are choosing wind and solar power now, because they are friendly to the environment.

Small changes can bring big results. Saving electricity is a simple way to protect our earth.
