Although about 80% of world’s population lives in developing countries yet the total energy consumed by the developing nation is only 40% of the world total energy consumption, the rest 60% of the energy is consumed by developed nations.
The rapid population growth in the developing nations over the past 25 years has kept the per capita consumption low compared with high industrialised developed countries.
The world average energy consumption per person is estimated to be about 2.5 tonnes of coal.
The industrialised countries use more then 4-5 times more than the world average and roughly 9-10 times the average for the developing countries. An average American uses almost 35 times more energy than an average Indian.
