ENERGY EFFICIENT WORLD

Improvements in energy efficiency usually means a reduction in the energy used for a given service like cooling, heating, lighting, water supply, etc. This can be achieved through change of technology, change of fuels, better organisation of the process, more efficient management or behavioural changes.

Energy efficiency is connected with economic efficiency as the reduction in use of energy means reduction in cost of producing each unit of GDP. But reduction in energy use because of the increase in cost of the energy cannot be included in energy efficiency.

The greatest factor contributing to the improvement of energy efficiency is the advancement of technologies for tapping the renewable energy sources like the sun and wind. When this factor is given enough importance by economists, scientists and political leaders all over the world, the world will be an energy efficient place with all the members of the human race enjoying decent living conditions at affordable cost.
