Be an ENERGY star!
House-Energy - Tips and information to help homeowners reduce energy use and carbon emissions.
- Drive Less! bike, take the TARC bus (free with UofL ID), carpool, or whenever possible. You'll stay fit, make friends, save thousands of dollars per year, and drastically reduce your energy use and planetary impact. Use Cardinal Directions to set-up carpools and explore all your options. ,
- Avoid the trip all together: Rather than polluting the planet and wasting fuel, money & time to get everyone in the same room, consider holding virtual meetings and classes through Teleconference, Microsoft Teams, Zoom Meetings, WebEx, or other audio and video conferencing services.
- If you must travel, don't fly! Flying causes 5-10 times more pollution per passenger-mile than ground-based options. It accounts for 5.5% of UofL’s total carbon footprint. Consider greener, less sardine-like options that keep you on the ground: carpool; take the train or bus (Megabus, Miller & Greyhound all serve Louisville directly, and you can catch Amtrak in Indianapolis or Cincinnati).
- If you must fly, at least invest a few extra bucks to offset your carbon emissions through a service such as Carbon Footprint Ltd, Native Energy, CarbonFund, TerraPass, or for free (through commissions) with UCapture.
- Keep tires properly inflated to save on gas (efficiency is reduced 1% for every 3 PSI that tires are under-inflated).
- Don't let engines idle longer than about 30 seconds. Idling longer wastes fuel and an idling engine produces more pollution than a moving vehicle.
- Set computers to "sleep" or “hibernate” when idle (under Control Panel > Power Options). Especially important for desktop models.
- Always shut down your computer when you're done. Any system updates can be made when you reboot.
- Turn off any peripheral devices (printers, monitors, speakers, scanners, etc.) when you're done. Just plug them all into one power strip and click it off, or use a "smart" power strip which automatically shuts off power to peripherals when the computer shuts down.
- Do not run a screen saver. They waste energy. Instead, set your monitor to enter power-saving mode when idle.
- Turn off lights, computers and equipment off when vacating a room.
- Unplug chargers, TVs, computers, and other equipment when not in use (many consume electricity even when the unit is turned off!). An easy solution is to put everything on one power strip and click it all off when you're done.
- Set thermostats moderately (<70°F winter / >75°F summer) & adjust 10°F when vacating a room.
- Get a handle on your residence hall's real-time energy consumption and observe the impact of your efforts to reduce with !
- Replace wasteful halogen or incandescent light bulbs with more efficient LED or compact fluorescent lamps (CFLs).
- In labs, always keep the fume hood sash closed while not in use.
- Air-dry laundry with a clothesline or rack instead of energy hogging clothes dryers.
- UofL energy supplier, LG&E offers a series of short videos with basic tips to help you stop wasting energy and water.

Green Your Laboratory to reduce toxins and waste:
1. Inventory Control: Keep chemical inventories updated to minimize duplicate ordering. Chemical purchases can also be reduced by borrowing and sharing chemicals between labs. DEHS offers a Chemical Exchange Program (CHEMEX) for chemicals that are unopened or partially used.
2. Product substitution: Review procedures with an eye to eliminating the use of hazardous chemicals by replacing with a less hazardous or non-hazardous alternative.
3. Replace mercury-containing thermometers with non-toxic substitutes.
4. Reuse empty chemical bottles to collect chemical waste.
5. Switch from disposal plastics items (beakers, pipettes, culture dishes, tubes, etc) to reusable glassware that can be autoclaved or disinfected/inactivated with a mild chemical solution (most inactivations effectively use 10% bleach, which can be sink disposed).
