CEO Rob Katz issued a mandate this spring to the company's divisions to cut energy use by 5 percent this year and another 5 percent next year.
Energy-saving techniques include new lighting fixtures, new light bulbs and timers for lights and heating. Vail Mountain has also replaced snowmaking equipment so snow guns need less air to blow snow.
The resort is even looking at training SnoCat drivers to manage their throttle and tiller better to save energy.
Solar panels and infrared photography to find where heat is escaping from buildings are other strategies.
