• Put on more layers of clothing to keep warm. You can take off a sweater when you're active, then put it back on when you're not.
  
  
• Turn off television sets, stereos and other electric appliances whenever you're not using them.
  
  
• Move furniture away from heating and cooling registers or radiators. Blocking or restricting airflow makes heating and air conditioning systems work harder. If the vent is located inconveniently, install a deflector and direct the hot or cold air right where you want it. They're inexpensive and easy to install.
  
  
• Consider using solid-state dimmers with your incandescent lights. When you finish using a reading or work light, you can dim it for general room illumination.
