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 greenhouse gases
which is contributing to global warning 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.
