ACTIONS THAT WILL TAKE SOME PLANNING AND/OR HOME REMODELING:

1 Shut off lights and appliances when you leave the room.

2 Use task lighting and shut off general and overhead lighting.

3 Change incandescent bulbs to compact fluorescent lamps (CFLs).

4 If you are near a window, use natural daylight, not 

electric lighting.

5 Use the ENERGY STAR settings in your computers, printers, copiers, 

and appliances to power down when idle. But remember to shut 

them off when you are finished using them and at the end of the day.

6 Use a power strip to shut off computers, printers, speakers, and 

mobile phone chargers when not in use (phantom loads).

7 Print and copy on both sides of the paper.

8 If possible, lower air-conditioning use by raising the thermostat.

the door.

teeth, etc.

2 Keep your tires properly inflated.

3 Do not let the vehicle idle for long periods.
