The to a greater extent energy we meet at our command, the better we can replete our desire for food, clothing, shelter, warmth, light, transport, communication, and manufacture goods. In the advanced countries, the vivification measuring stick of living is already high and populations are stable, so their require for energy is not probable to grow very much. Th is claim whitethorn even decline as energy use becomes more(prenominal) efficient. elsewhere rates of energy consumption are still low, little than 1 kW per person for more than half the mountain of the world compared with 11kW per person in the fall in States. These tidy sum seek better lives which means more energy, and their poetry are increasing rapidly, which means still more energy. A depart of burning fossil fuels is the formation of cytosine dioxide when the carbon they verify combines with the air travel that acts to trap heat by the nursery effect. This is mainly responsible for the warming of the earth?s halo that is going on today, a warming that will apparent have serious consequences for our planet.
