Energy advice
- Power saving settings: Enable power-saving modes on computers, printers, and monitors to reduce energy use when idle.
- Smart power strip: Turn off power to all your devices with one switch when you're done.
- Shut it down: Shut computers down completely at the end of each workday. This can help extend the life span of the equipment too.
- Light the right way: Switch to LED bulbs. Save on energy and costs.
- Natural light: Position your desk to make the most of it – less need for lamps.
- Heat smart: Use a small energy-efficient space heater to warm just your workspace.
