To wit, Vail Resorts will power its 15 U.S.-based ski resorts with 100 percent wind energy beginning in 2020, and is well on its way to achieving its ambitious 2030 goal of "zero net emissions, zero waste to landfill and zero operating impact on forests and habitat." Nearby, Aspen Skiing Company is big on solar, donates six figures annually to local non-profits working on climate mitigation and related issues, and lately has focused on firing up its customer base to encourage climate-friendly voting in Congress. Meanwhile, the list of ski resorts now deriving all of their power from on-site renewables (e.g., Berkshire East, Jiminy Peak, Squaw Valley, Wolf Peak, Arapahoe Basin, Breckenridge) is growing every year. Coordinating and facilitating much of this activity is the National Ski Areas Association (NSAA), a trade group representing over 300 U.S-based ski area owners and operators.
