Heating and cooling accounts for almost half of our annual home energy consumption. You can personally reduce nearly 2,000 pounds of carbon emissions annually with a few simple adjustments. The American Council for an Energy Efficient Economy has more tips for saving energy on heating and cooling.

Here are a few things you can do to make a difference:

Move your thermostat down 2° in winter and up 2° in summer

Install a programmable thermostat
Programmable thermostats will automatically lower the heat or air conditioning at night and raise them again in the morning. They can save you $100 a year on your energy bill.

Clean or replace filters on your furnace and air conditioner
Cleaning a dirty air filter can reduce nearly 350 pounds of carbon emissions annually.
