We use many different energy sources to do work for us. Energy sources are classified into two groups - renewable and nonrenewable. Non-renewable energy sources are those that take millions of years to form and will run out some day. It is energy that comes from fossil fuels such as coal, crude oil, and natural gas. Fossil fuels are mainly made up of carbon and were formed millions of years ago. The chemical reaction which takes place when we burn fossil fuels releases carbon compounds such as carbon monoxide and carbon dioxide into the air. Carbon dioxide is one of the green house gases which is contributing to global warming and air pollution. On the other hand, renewable energy sources will never run out, are better for the environment and do not cause pollution. Renewable energy is often called green energy because it is a natural energy, always available and does not have to be formed like nonrenewable energy. The green energy is always there. For example, the Sun consistently shines, water is abundant, and the winds blow throughout the year. The five types include solar, energy from the Sun; geothermal, energy from heat within the Earth; hydroelectric, energy from moving water; biomass, energy from dead plants and microorganisms and finally, energy from the wind.

In a lost age, the world is divided into four nations: the Water Tribes, the Earth Kingdom, the Fire Nation, and the Air Nomads. Within each nation, there is a remarkable order of men and women called the "benders" who can learn to harness their inborn talent and manipulate their native element. Bending is a powerful form combining martial art and elemental magic. In each generation, only one bender is solely capable of controlling all four elements. That bender is the Avatar. The Avatar is the spirit of the world manifested in human form. When the Avatar dies, it reincarnates into the next nation in the cycle. Starting with the mastery of his or her native element, the Avatar learns to bend all four elements. Throughout the ages, the countless incarnations of the Avatar have served to keep the four nations in harmony. Then, the Fire Nation launched a war against the other three nations. Just as the world needed the Avatar the most, he mysteriously vanished. A hundred years later, the Fire Nation is near final victory in its ruthless war of world domination. The Air Nomads were destroyed, the Air Temples ravished, and all airbender monks eradicated. The Water Tribes were raided and driven to the brink of extinction. The Earth Kingdom remains and fights a hopeless war against the Fire Nation. Many believe the Avatar was never reborn into the Air Nomads and the cycle is broken. In the desolated South Pole, a lone Water tribe struggles to survive. It is here that the village's last remaining waterbender Katara and her warrior brother Sokka rescue a strange 12-year-old boy named Aang who has been suspended in hibernation in an iceberg. The Water tribe soon discovers that Aang is not only an Airbender--the extinct race no one has seen in a century--but also the long lost Avatar. Now Katara and Sokka must safeguard the child Avatar in his journey to master all four elements and save the world from the Fire Nation.
