- A high-end computer gaming system may use more than 450 watts of electricity.
- A laptop in sleep mode uses only 1 watt or less.
- An average campus desktop computer and monitor using 100 watts for 10 hours (1 kWh) consume electricity that emits an estimated 0.0016 pounds of nitrogen oxide, 0.0066 pounds of sulfur dioxide and 1.2 pounds of carbon dioxide.
- You can estimate your annual emissions with EPA’s interactive Power Profiler.
Here’s how you can reduce computer-related carbon emissions:
- Activate your power management settings
Energy Star recommends setting computers to enter standby or hibernate mode after 15-60 minutes of inactivity and monitors to enter sleep mode after 5-20 minutes of inactivity. On your laptop, activate both AC and battery power-saving profiles. To find out how, consult your computer’s online Help or see Activate Power Management on Your Computer.
- Deactivate your screensavers
Screensavers are not needed to “save” modern computer screens. They use a lot of power and may override your power management settings.
G Suite, web conferencing, NCSU Libraries’ Electronic Resources, the Virtual Computing Lab, online courses, webinars, and other IT tools at NC State make it possible to work and study online instead of driving to and from campus.
- Turn IT off
Don’t leave your computer running all night unless you are using it and don’t power up your peripherals (e.g., printers, scanners) until you need them. It does not take more energy to power up your computer than it does to keep it running.
Did you know?
- Since the early days of the digital revolution and the idea of “the paperless office,” the use of paper globally has actually tripled.
- In 2006, an average office worker printed 10,000 sheets of paper a year – that is 20 reams of paper or about 83 percent of one tree, in addition to an outrageous use of water and energy for processing.
- The USA consumes the most paper of any country – six times more per person per year, which translates to approximately 3.2 billion reams, or about 168 million trees.
Here’s how you can help to reduce these numbers:
- Print less
- Read documents and emails onscreen.
- Prepare “print-on-demand” .pdf files instead of printing.
- Print on both sides of paper when you can.
- Conduct business transactions electronically instead of in-person or by mail – this will save gas and transport emissions, too.
- Recycle more
- Use paper that has recycled content.
- Remember to recycle printed paper.
Save the planet!
Did you know?
- “Greening with IT” is part of The Solution!
- Globally, information and communication technologies (ICT) are said to contribute about 2 percent of the world’s carbon emissions.
Here’s how we all can all reduce that impact:
- Purchase EPEAT-certified electronics
EPEAT ranks electronics based on environmental impact from factory to landfill.
- Donate old computers and mobile devices to others, but make sure you delete any personal information first!
- Bring your unusable electronics to a reputable e-cycler.
- Visit Recycling Guide.
- Think big!
- In your studies and research, use ICT to learn new ways to create sustainable solutions for the world’s problems.
