Summary
Today most of our energy needs are supplied by the fossil fuels. In one hundred years coal will be the only one left as petroleum products may remain only for 3 to 4 decades. Little of stored energy will be left if we continue to use energy at the same rate. Fossil fuels are non..
Sun, the natural source of energy
We derive heat energy by burning fuels like coal, charcoal, wood, kerosene, petrol, etc. Electricity is another source of heat energy. Electrical energy is converted to heat energy and thus, used as a source of heat energ..
