Definition - What does Energy Efficiency mean?

Energy efficiency is defined as the use of energy in an optimum manner to achieve the same service that could have been achieved using a common less efficient manner. Energy efficiency is the practice of reducing the energy requirements while achieving the required energy output.

Energy efficiency may also be stated as "efficient energy in use.”

Corrosionpedia explains Energy Efficiency

Energy efficiency and its practices are a part of a sustainable energy policy. Energy efficiency can be achieved with renewable sources of energy such as solar, wind or hydro, or by changing the power consumption requirements so that the overall energy consumption is reduced without compromising the output received.

For example, using the proper insulation material at the necessary locations helps a building use less energy for heating and cooling while maintaining a comfortable temperature. Similarly, using LED lights and natural sunlight helps to reduce the amount of energy required to attain the same level of illumination that could be traditionally received by incandescent light bulbs.

Following proper energy efficiency practices reduces the energy cost to industries and results in overall cost savings to the organizations and their customers. Also, the environment is improved due to a reduction in greenhouse gas emissions and a lower probability of environmental corrosion attack on structures, buildings and equipment.
