Energy efficiency is the ratio of energy input to energy output. It can be thought of as the percentage of energy going into a process or usage that is beneficially consumed rather than being wasted. Energy is widely used for heating and cooling, to produce electricity, and to power vehicles, equipment, and industrial processes. Whatever the purpose, energy efficiency is maximized when energy waste is minimized.
Optimizing energy efficiency has many socioeconomic and environmental benefits. The world is heavily dependent on fossil fuels, which are a finite resource. Obtaining the highest energy output possible for each use helps conserve fossil fuels and saves consumers money on energy costs. It also limits the environmental damage caused by fuel production and consumption,...Read more
