Using Energy Judiciously:
The total coal reserves in our country are estimated to be about 80 billion tonnes, but we are consuming it at a rate of 250 million tonnes per year. At this rate the resource that nature produced over millions of years will be consumed in just a few hundred years! The situation is more alarming in the case of oil (petroleum) reserves. The known oil reserves of our country are about 500 million tonnes only, of which we are consuming 30 million tonnes per year. So, the oil reserves will last for a few decades only. The demand for energy is increasing every day.
The increasing demand cannot be met for a long time unless new resources are harnessed, since conventional, nonrenewable energy sources are depleting very fast.
