We all need different types of energy in our daily life to perform different tasks. We get energy from different natural resources like coal, petroleum, and electricity. Again, electricity comes from different sources hydro-electricity, thermal electricity and some alternate sources of energy like electricity from solar energy. Alarming Situation of Natural energy sources Stock Natural sources of energy are limited because of their limited stock. It takes several years in formation of natural energy sources but if the consumption of energy sources will be too more (like in current situation) than the rate of their formation, they will not last longer. Even the stocks of energy sources like petroleum are limited to certain areas and they have monopoly on petroleum market, resulting drastic increase in rates of petroleum during last decade.
