The sun release a very little of energy everyday.

Oil, coal and natural gas are infinite. People around the world can use them for more billion years

Water power gives energy without polution.

If the wind does not blow, there is wind energy.

Solar panels on the roofs of houses may not create enough energy to heat or cool an entire house

In the future, alternative sources of energy may replace fossil fuels.

Solar energy is not only plentiful and infinite but also clean and safe.

Geothermal heat is available only in a few places in the world.

In the central of Vietnam, we can see a variety of windmills.

People must develop and use alternative sources of energy for human beings' needs in the future.

The sun, water, and the wind are other alternative sources of energy.

Water power is inexpensive, so they are used a lot. For example, there are a lot of hydroelectricity in Vietnam.

Because power demand is increasing very rapidly, fossil fuels will be exhausted within a relatively short time.

The solar energy is convenient because this can be changed into electricity.

The wind can't turn windmills and move sailboats.
