Sunapee General Manager Jay Gamble said the resort will start using biodiesel fuels in its operations this winter. Biodiesel B-20 will be used in snow grooming equipment and snow removal heavy equipment. Biodiesel B-5 will be used to heat base lodges and buildings.
The ski area will be using wind energy again this year. Along with sister resorts Okemo in Vermont and Crested Butte in Colorado, Mount Sunapee renewed last year's agreement with Sterling Planet to replace onto the grid 100 percent of its electrical power consumption with wind-generated energy.
Mount Sunapee is also pushing energy efficiency programs, which include more efficient snowmaking, and on-going recycling efforts.
