Energy & Water Conservation at Yellowstone National Park

  • Installed a “tunnel washer” in the laundry and employs a water recovery system that saves 3,500 gallons of water daily for the 2.2 million pounds of laundry we wash annually.
  • In 2011, the Mammoth Hotel Dining Room became certified as a Green Restaurant by the Green Restaurant Association, a non-profit organization that provides a way for restaurants to demonstrate their commitment to environmental sustainability. The Mammoth Dining Room is Xanterra’s first certified green restaurant, and with a 3-Star rating, it’s the FIRST 3-Star certified restaurant in Wyoming, and one of only 71 in the country. To achieve its 3-Star Green Restaurant certification, the Mammoth Hotel Dining Room installed waterless urinals, high-efficiency hand dryers, dual-flush toilets, and super energy efficient LED lamps, and sources of local, organic, and sustainable cuisine, including Marine Stewardship Council certified salmon.
  • During the fall of 2011, several large-scale lighting retrofits occurred in our General Accounting Office and all of the facilities in Gardiner, MT. This project involved the retrofitting of all existing T-12 fluorescent lighting to more energy efficient T-8 bulbs and electronic ballasts. These T-8 bulbs not only consume less electricity, but have a higher light output.
  • Replaces towels and linens in guest rooms after three days to reduce water and detergent use unless visitors request more frequent replacement.
  • Shuts down boilers where applicable on locations during times of low demand. Some boilers operate on clean propane or biodiesel.
  • Replaced to date over 25,000 incandescent bulbs with Compact Fluorescent Lighting (CFL’s). CFLs are 75% more efficient and last 10 times longer than incandescents.
  • Rebuilds vehicles, thereby reducing the need for natural resources and energy to generate new vehicles.
  • Implemented an aggressive energy management program in Food & Beverage focusing on managing and minimizing energy use including water, electricity, and propane. We distribute posters, stickers, and checklists that make managing the program straightforward and user friendly.
  • Housekeeping has created an energy conservation program that includes unplugging appliances (hair dryers and fans) in vacant/due-out guestrooms to conserve energy.
  • In 2008, Xanterra’s engineering department designed, tested, and implemented equipment allows the 10,000 gallons of cooking oil generated from food service to be injected directly into the boiler system for fuel. This project achieves significant environmental gains, most notably by reducing annual carbon dioxide emissions by 223,800 pounds from the replacement of 10,000 gallons of diesel fuel with cooking oil. The project also eliminates the fossil fuels (and the associated 12,729 pounds of CO2 emissions) needed to transport the material offsite for recycling.
  • Replaced 20 watt halogen bulbs with 3 watt LEDs in the gift shop at the Old Faithful Lodge—this reduces greenhouse gas emissions by over 6 tons a year!
  • Upgraded over 500 light fixtures at Mammoth from T-12 to T-8 lamps (which use on average 35% less energy), and reduced number of existing lamps by half.
  • Because on-site generation of renewable energy can be quite challenging within the boundaries of a National Park, Yellowstone has included the purchase of Renewable Energy Credits (RECs) in our environmental portfolio. For 2011, we purchased 5,300,000 kilowatt hours (kWh) of American Wind from Renewable Choice Energy. This accounts for approximately 35% of our total electricity usage. RECs are intended to reduce the impacts from the use of electricity when on-site solutions may not be available. By purchasing RECs, Xanterra is taking responsibility for our environmental impact and raising awareness of the changes that are needed in the way our business operates and how we impact the world around us.
  • Utilizes vendor misers—a power saving device—on most of the parks vending machines.
  • Replaced old coffee makers with Keurig® brewers. On average, the machines save 16 oz of water per day and reduce energy use by 90%.
  • Upgraded Mammoth Dining room lights with 330 LED lights from Eco-Story, which will save 86,000 kwh and reduce greenhouse gas emissions by an estimated 67 tons annually.
