The importance for conserving energy is as follows:

1. Energy is essential for economic and social development and also improved quality of life. Large-power industrial companies need reliable power and energy supplies. However, the current global pattern of energy supply and use is not sustainable. Encouraging energy conservation among consumers is often advocated as a cheaper or more environmentally sensitive alternative to increased energy production.
2. The substantial increase in global energy consumption in the coming decades will be witnessed in the developing world. Strong economic growth in many developing countries is already leading to a sharp increase in per capita energy consumption. Consumption continues to rise, driven also by the projected two-fold expansion in world population during the 21st century which will occur mostly in the developing countries.
3. In an era marked by a heightened awareness of finite natural resources, there is a incessant need for energy conservation to reduce costs, reduce dependency on foreign energy sources, minimise the environmental effects of consumption and conserve resources for future generations.

Energy conservation is a particularly effective way of reducing living costs and the cost of government operations on external disadvantages promoted by excessive use of natural resources and degradation of the environment.
