Answer:
Energy efficiency is "using less energy to provide the same service". In other words, energy efficiency, sometimes called efficient energy use, is using less energy to provide the same level of performance, comfort, and convenience. In general, efficient energy use is achieved by using more efficient technologies or processes rather than by changing human behavior.
Energy efficiency offers a powerful and cost-effective tool for achieving a sustainable energy future. Improvements in energy efficiency can reduce the need for investment in energy infrastructure, cut energy bills, improve health, increase competitiveness and improve consumer welfare. Environmental benefits can also be achieved by the reduction of greenhouse gas emissions and local air pollution. Energy security – the uninterrupted availability of energy sources at an affordable price – can also profit from improved energy efficiency by decreasing the reliance on imported fossil fuels.
However, it is important to highlight that energy efficiency is not energy conservation. Energy conservation is reducing or going without a service to save energy. Energy efficiency is a way of managing and restraining the growth in energy consumption. Something is more energy efficient if it delivers more services for the same energy input, or the same services for less energy input.
