Explanation: Conventional energy sources like Coal, Petroleum, Natural gas, etc, are major causes of pollution and ozone layer depletion. There are limited reserves of conventional energy sources, which are bound to be finished. At the current rate of consumption, the approximate lifetime of the world’s petroleum, natural gas, and coal reserves are 50 years, 52.8 years, and 153 years, respectively.
