True
Fossil fuels like coal and petroleum takes millions of years to form. The rate of usage of fossils is not equal to its formation. As the rate of formation is slow it is important to use energy in an efficient way so that it is not consumed in a wrong way. The transformation of energy should be more efficient to avoid the wastage of energy. By doing this we can decrease the consumption of fossil fuels as it cause pollution in the environment. The burning of fossil fuel releases carbon dioxide, nitrogen oxide ,and other harmful gases which is injurious to the health of people. So, the fossil fuel should be used in a decreased manner.
