SALT LAKE CITY — Beginning this month, Rocky Mountain Power customers will receive their billing statements in new reusable envelopes they can also use to send their payments. This switch aims to help keep operating costs low and benefit the environment. Last year, the utility sent more than 16 million return envelopes to customers and 5 million were used to return payments, said Karen Gilmore, Rocky Mountain Power vice president of customer service.

"With reusable envelopes we're eliminating the need for a separate return envelope," Gilmore said. "This change has the potential to conserve up to 1 million pounds of wood, 3,200 trees and 3.7 million gallons of water and avoid nearly 1 million pounds of carbon emissions each year."
