If you’re a college student, you may not have energy efficiency on the top of your mind as you return to campus. But college dorm life can have a big impact on the health of our planet.  

In fact, the average 200 square-foot dorm room can generate as much greenhouse gas pollution as the tailpipe emissions of a car driven more than 2,000 miles.

For Energy Efficiency Day this year, take the challenge to green your college dorm room. Use this checklist:

Keep Your Cool

Air-conditioning packs a big punch for dorm power usage. Residential and commercial cooling alone accounted for 10 percent of total U.S. electricity consumption in 2020. If your room has individual temperature control, you can set it a few degrees higher to help cut back on how much energy the cooling system uses. Never leave a window open when an air conditioner (or heater) is running; and on hot, sunny days, keeping the blinds or curtains closed will block many of the sun’s warming rays. In the winter, this will help keep the cold out, too.

Year-round, report broken windows, cracks in doorways, or any damaged thermostat controls to the university maintenance department. 

Be Bright about Lighting

Switch off your overhead light, desk lamp, and any other lights every time you leave the dorm. To take your environmentalism a step further, if the bulbs provided aren’t LEDs, consider swapping some in. LEDs use at least 75 percent less energy, and last 25 times longer, than old-fashioned incandescent bulbs. (Find tips on how to shop for energy-efficient bulbs here.)

If you decorate with a string of holiday lights, make sure those are LEDs too. Consider putting them on a timer so that they don’t waste energy when you aren’t in the room.

Be smart with your room layout. You won’t have a say in the size of your room, but you can control how you arrange what’s in it. For example, if you put your desk next to a window that gets a lot of natural light, you won’t need to turn on a desk lamp while you’re working during the day.

Unplug Everything

The average dorm room consumes 30.2 percent of its electrical energy while you and your roomies aren’t there, according to one study. That’s because appliances continue to draw power from electrical outlets even when turned off or idle

The Department of Energy found that in the average dwelling, 75 percent of all electricity used to power electronics is consumed after the products are turned off. A power strip or surge protector helps avoid this: You can plug all your appliances and devices into it, then easily flip one switch to stop them from drawing power.

Don’t Make Your Screens Work Too Hard

If you have a television, look for an energy-saving feature called Automatic Brightness Control. It adjusts the picture brightness level to the amount of light in the room. 

Game consoles can be huge energy drainers if used to stream videos or if constantly left on. Instead, stream with apps already on your TV or with a streaming device (like Roku or Apple TV), which require one-fifteenth of the energy. Keep the auto-power-down feature enabled so your console doesn’t consume power unless you are actually using it.

Computers are college necessities, and as with your gaming console, you can typically program your computer to go into a low-power standby mode when you’re taking a break. Look for an energy-saving or eco-mode.

Reduce Water Use

If you have a dishwasher in your room or suite, run it only with a full load; the same goes for doing laundry. Wash clothes in cold water and consider using a drying rack instead of an electric clothes dryer, which often uses as much energy as a new refrigerator, dishwasher, and clothes washer combined. Also, using cold water and air drying means you will be less likely to shrink or discolor your clothes if this is your first time doing laundry away from home!

If you live in an apartment-style dorm, add a faucet aerator to your sink. Aerators can reduce water flow to 1.5 gallons per minute or less from the standard flow of 2.2 gallons per minute. They are inexpensive and easy to screw onto the nozzle of your faucet, and they save energy by reducing your hot water use.

Finally, get your college to join in on Energy Efficiency Day 2021 by asking them to issue a proclamation. You can find all the resources you need in this helpful tool kit:
