Įnergy can be conserved by reducing wastage and losses, improving efficiency through technological upgrades, and improved operations and maintenance. It also lowers energy costs by preventing future resource depletion. It is at the top of the sustainable energy hierarchy. Energy conservation measures (ECMs) in buildings reduce the need for energy services and can result in increased environmental quality, national security, personal financial security and higher savings. Energy conservation is a part of the concept of Eco-sufficiency. This can be achieved either by using energy more efficiently (using less energy for a constant service) or by reducing the amount of service used (for example, by driving less). For the law of physics, see Conservation of energy.Įnergy conservation is the effort made to reduce the consumption of energy by using less of an energy service. This article is about sustainable use of energy.
