Tips & Suggestions
The peak mobile app will educate users on how to modify behaviors in accordance with energy usage levels. Here are the peak mobile app's tips and suggestions to change energy consumption habits and minimize peak demand.
Control Inside Temperatures
Back to top
Ideal Inside Temperature
- In Winter Months:
- When you are in: 68-72 degrees
- When you are out: 60-65 degrees
- When you are away for the weekend: 55 degrees
Unplug Unused Items
- Phantom energy is the electricity that electronics pull from the outlet while plugged in, even when the device is off. This phantom load can account for 13 (a radio) to 1,450 (a TV) kWh of energy.
Let the Sunshine In
- In the winter months, open the curtains during the day if the window is receiving sunlight. Shut the curtains or shutters after dark to trap in the warm air and prevent drafts.
- Use ceiling fans year round:
- In the summer, use the ceiling fan in the counterclockwise direction. While standing directly under the ceiling fan you should feel a cool breeze.
Light Shine Bright
- Dust light fixtures regularly. A heavy coat of dust can block up to 50 percent of the light output.
Rearrange your Furniture
- Keep lamps away from thermostats; the heat produced can cause your furnace to run less than needed or your air conditioner more than needed.
Smart Window Treatments
- In summer months, curtains with light color backing reflect sunlight rather than absorb the heat. During the heat of the day, keep curtains closed to block the heat before it has a chance to enter.
Use Lighting Effectively and Efficiently

Turn off unused lighting
- The more we get used to do this simple task, the greater our impact. The International Dark-Sky Association in Tucson, Arizona, an environmental group, estimates that one third of all lighting in the U.S. is wasted.
Install Energy Star Bulbs
- When replacing lighting, make sure the bulb is energy star rated. Earning the ENERGY STAR means products meet strict energy efficiency guidelines set by the US Environmental Protection Agency.
Replace 60 Watt Bulbs
- An incandescent bulb uses 60 watts, but costs $1-$3, annual cost $11, lasts 1,200 hours and emits 4500/lbs year.
Replace 75 Watt Bulbs
- An incandescent bulb uses 75 watts, bulb costs $1, annual cost $9 and lasts 1,000 hours.
Think About It
- Most dorm rooms have about 5 or more bulbs and there are 6,388 dorm rooms on campus. That is 31,940 bulbs in dorm rooms alone.
Utilize Task Lighting
- Use light where you need it, when you need it. Focus the light wehre you need it so you are not brightly lighting an entire room.
Lighting Control Devices
- Use lighting control devices like dimmers, motion detectors, occupancy sensors, photcells, and timers to provide light only when you need it.
Give the Appliances and Devices a Break

Wait to Dry your Clothes
- Drying a load of wash in an electric dryer generates more than 3 kilograms of greenhouse gas. Use the sun (or a clothes rack) whenever you can-it's the most environmetally friendly dryer.
Clothes Washing Tips
- Wash only full loads of clothes, and be sure to set the water level appropriately. You could be wasting up to $150 annually by not washing full loads.
- According to a recent report by the Natural Resources Defense Council, the cable TV boxes in your home may use more electricity than your refrigerator. The average energy consumption of a typical household setup -- one high definition digital video recorder and one high-def set-top box -- is 446 kilowatt-hours a year. A 21-cubic-food Energy Star top-freezer refrigerator, on the other hand, uses 415.
Energy Star Appliances
- Energy Star rated appliances use up to 40% less energy.
Replace 100 Watt Bulbs
- You can replace a 100 watt incandescent bulb with a 26 watt CFL or a 20 watt LED. You can save approximately $10/year/bulb and they last 50 times longer.
Screen Savers Don't Save
- Energy. Turn off your computer. Leaving the screen saver on will not save any energy. Screen savers can use more energy than when you are us ing the computer yourself.
Use "Smart" Power Strips
- Deploy "Smart" Power Strips. There are three types of "smart" power strip:
- Timer-equipped: These power strips have outlets that are controlled by programmable timers.
- Occupancy sensing: Occupancy sensing power strips have outlets that are controlled by a motion detector.
- Current sensing: These power strips can automatically turn several outlets off or on when they detect that a monitor either enters a low powered sleep mode, is turned off, or is turned on.
- A computer with a 17 inch LCD monitor left continuously running will cost approximately $128 a year. Turning a computer off at night so it runs only 8 hours will cost only $43/year.
Take the Stairs
- If every student on campus took the stairs instead of the elevator once everyday, it wouldsave about $5,600/year.
Wait to charge devices
- A cell phone or a tablet uses about 12kWh/year. Assuming each student has 1.5 of these types of devices, this costs the university an estimated $50,400 annually.
Air Dry your Hair
- Blow-drying your hair uses energy, but air-drying is free. If you shower daily and use the blow-dryer for 20 mintues after each shower, you can cut more than two hours of energy us per week.
- Ensure all fume-hood sashes are cloosed, and all fume-hood lights are turned off.
Communicate and Educate
Back to top
Tell Your Friends!
- If a peak alert has been initiated, let your friends and building mates know what they can do to help the campus to reduce their electric usage.
Office of Sustainability
- The mission of the IU Office of Sustainability is to catalyze a thriving culture of sustainability in academic, research, operations, administration, campus life and community outreach to enhance environmenal health, economic prosperity, and social equity.
What Else Can I Do?

Shorten your shower
- Take shorter showers. Water takes a lot of energy to heat, about 129 watts per gallon. Reducing your shower time by one minute will save 1,355 watts-that's 249 iphone charges!
Mac Energy Saving Tips
- Mac-books uses less energy than i-Macs
- Dimming the screen on your Mac-book prolongs batter life
- Your computer does not use that much energy for a long period of time when sleeping.
