Energy Efficiency, sometimes simply called efficient energy use, is all about using less energy to provide the same level of energy service.
Energy services are linked to well-being and have the potential to impact on almost every area of human life.
The energy sector can play a significant role in reducing environmental damage and its harmful consequences by introducing renewable energy sources, substituting cleaner fuels for dirty ones, and increasing energy efficiency.
Whether during generation and production, transport or transmission, or end-use, a, increased in energy efficiency can have wide-ranging benefits. It has been proved to be a cost-effective strategy for building economies without necessarily growing consumption.
The ability to capture the full extent of these benefits will depend on the initial cost of less efficient appliances and that of replaced energy-efficient technologies and on the existing technical standards for energy efficiency.
In industrial settings, there are abundant opportunities to save 70% to 90% of the energy and cost for lighting, fan, and pump systems; 50% for electric motors; and 60% in areas such as heating, cooling, office equipment, and appliances. In general, up to 75% of the electricity used today could be saved with efficiency measures that cost less than the electricity itself.
