Demand for electricity increases the colder it gets. In this week's Generations of Energy - homeowners are asking to conserve if they can. P-P-L is one of many utility companies along the east coast that has asked customers to conserve electricity this winter. It's a way to make sure there's enough power supplies to go around. If you lose power for some reason, PPL says you can report it through the toll free number, 1-800-DIAL-PPL.
