When using a dryer, wait until you have a full load. Also, separate drying loads into heavy and lightweight items. The lightweight items take less time to dry, so the dryer doesn’t have to be on for as long with these loads.
Do not use screen savers. It is far more efficient to use the power down settings available, or to encourage staff to switch off their computer monitors when away from their desk as they consume power.
Decorate with pale colors on walls, ceilings and floors. Soft tones reflect more light, so you can use lower wattage bulbs and delay turning on lights until later in the day. Using high-gloss paint can help as well.
When installing new lighting, make sure that lights in darker areas, or more remote areas, can be switched on and off independently of other lights this can save considerable amount of Electrical consumption
