of the questions.
Almost all our energy comes from oil, coal and natural gas. we call them fossil fuels. The
earth's fossil fuels are running out. What would happen if there were no oil, coal and gas on Earth?
Scientists are trying to find and use other alternative sources of energy. We can use energy from the
Sun, the wind and the water.
Solar energy is unilimited. It supplies all the energy used to grow plants, to evaporate water
for rain and to maintain the temperature of the plants. All are necessary for human life. If we're
able to collect solar energy, we'll be sure to make good use of this abundant source of power.
Another source of energy from nature is the wind. wind power is clean and plentiful. Enegry from
the wind has been used for centuries to move ships, grind grain, pump water and do other kinds of
work. In more recent time, wind power has been used to generate electricity.
Water can also provide power. For a long time, people have used water to power machines.
Some early uses of water were to mill grain, saw wood and power machinery for the textile industry.
today water power is mostly used to generate electricity.
