Green Tip of the Week
Tip 24: Turn off your computer at night
Remember to turn off your computer and monitor screen when you leave the office at night. Computers account for roughly 42 percent of the electricity used in our offices. Although many people think that turning on your computer uses a lot of electricity, it’s really the same as letting it run for only 3 minutes. Computers have a long life and use 67 percent less energy if they are turned off overnight.
Did you know that Chicago Union Station replaced existing lighting with energy-efficient bulbs and installed motion sensors in some locations resulting in a savings of 3,142,932 kWh or $336,402 annually?
This is enough electricity to power 285 U.S. households for a year. These simple changes will also reduce our carbon footprint by 3.9 million pounds!
Did you know that by installing reduced voltage starters on all 12 escalators, Chicago Union Station will save almost $10,000 and 78,418 kWh of energy every year? This reduced energy consumption by approximately 20%, while maintaining uninterrupted, 24/7 service.
Did you know that the average road locomotive spends 50% of its run-time in idle? That’s a lot of wasted fuel!
So, in 2005, Amtrak began installing Automatic Engine Start/Stop (AESS) systems in its locomotives. By the end of 2010, 156 (more than 75%) of Amtrak’s 205 passenger train locomotives had been retrofitted with AESS systems.
AESS is a fully-integrated software solution that monitors critical operating parameters and automatically shuts down an idle diesel engine, while keeping the locomotive in a perfect operating state—ready to restart on demand.
By investing in AESS systems, Amtrak:
• Reduced wayside noise for its passengers
• Improved fuel efficiency up to 10%
• Reduced annual emissions of nitrogen oxides by at least 247 tons and particulate matter by at least 8.25 tons
