Question

New Energy in the Twenty-first Century Energy from the wind.

All over the world, people use the power of the wind. It is a clean source of energy, and there is lots of it. But if the wind does not blow, there is no wind energy.

Energy from the water

When water moves from a high place to a lower place it has the power to make electricity. In Britain, waterpower produces enough energy to power a town with 40000 people. Waterpower gives energy without pollution, but people have to build dams(大坝) to use this kind of power, and building dams is very expensive.

Energy from the earth

There is heat in the rocks under the earth. Scientists use the heat to make geothermal(地热的) San Francisco gets half of the energy it needs from geothermal power. This kind of energy is cheap, but it is only possible in a few places in the world.

Energy from the sun

Solar panels(镶板) on the roofs of houses and buildings can turn energy from the sun into electricity. These panels can create enough energy to heat the whole house during winter. Solar power is clean and plentiful, but when the weather is bad, it can’t produce power.
