semiconductor electric boiler energy saving

Energy conservation - Wikipedia

Energy conservation is the effort made to reduce the consumption of energy by using less of an energy service. 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). Energy conservation is a part of the concept of Eco-sufficiency. ...
