Here's today's challenge:
Put on a sweater and turn down your thermostat to 65°- 68° when people are home and active and 55°- 58° at night as well as when no one is home. In warm climates, raise your air-conditioner thermostat 4° or up one setting. Home heating and air-conditioning are responsible for a large portion of our carbon footprint.
