Energy Sources

NON-RENEWABLE AND RENEWABLE ENERGY RESOURCES Energy resources can be divided into two broad categories namely non-renewable and renewable resources. Non-renewable sources of energy are those that we can use only once and we can not be able to use them again such as petrol, coal and diesel. Renewable sources of energy are those that we can use and still continue to obtain them such as the heat from the sun and wind energy.
