Embrace natural light. Open up your curtains and let the sun shine in! Using natural light whenever possible instead of relying on artificial light can greatly reduce the amount of electricity you use during the day. The same is true whether you work in an office or spend your days in your house. Exposure to natural light also increases happinessฺ
Try to arrange your workspace so that natural light floods your desk. Keep the overhead lights off when possible. When you need extra lighting, use a low-powered desk lamp instead.
Buy curtains or blinds in a light shade that provides privacy but still allows light to come through.
