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 will happen when there is no oil, coal and gas on the earth?

The sun supplies all the energy used to grow plants, to evaporate water for rain, and to maintain the temperature of the planet. All are necessary for human life. If we are able to collect solar energy, we will be sure to have this abundant source of power.
Another source of energy from nature is the wind. Wind power is clean and plentiful. Energy 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 power were to mill grain, saw wood and power machinery for the textile industry. Today water power is mostly used to generate electricity.
