Landscaping – Increase Shade
During the summer, sunlight streaming in windows forces an air conditioner to work harder, leading to increased energy use. While curtains can be closed, summer shade can be achieved by planting trees around your home.

Refrigerator and Freezer Operation
In most households, the refrigerator is the single biggest energy-consuming kitchen appliance, and a stand-alone freezer uses a comparable amount of energy.

Power Down
Personal computers use about the same amount of energy to start up as when they are on for about two seconds.
