Killington, Vt., one of the largest ski resorts in New England, will use 300,000 kilowatt hours of electricity made from manure generated on 13 farms this year to run its K-1 Express Gondola to the top of the resort's namesake 4,241-foot peak, a spokeswoman for the resort says. The manure-generated electricity is distributed through a renewable energy program at Green Mountain Power, the state's largest utility. The "cow power" program now generates five megawatts using manure from 10,000 of the state's 270,000 cattle.
