Adjust Window Blinds to Naturally Heat & Cool Your Home
A simple way to reduce home energy costs is to use your existing window blinds to help maximize your comfort, changing and adjusting them with the season. In the winter, open the binds on the windows that face south to let some sunshine and heat in during the day, and then close them at night. In the summer, be sure to keep the blinds and curtains on the south side of your house closed to protect against the sun's rays heating up your otherwise nicely air conditioned interior.
You'll save money on your heating and cooling bill, and adding natural (and free) light to your house in the winter will also reduce your electric bill.
In much of the spring and fall, you can turn off your heating and cooling system entirely -- open your windows and use natural fresh air to provide a comfortable temperature in your home.
