PG&E has some tips to stay cool and save energy during the hot summer months.


* Set your thermostat to 78 degrees when you're at home. Three to five percent more energy is used for each degree the air conditioner is set below 78 degrees.


* Shut windows to keep in pre-cooled air from the early morning hours and draw shades to keep the sun from warming the house.


* Use ceiling fans when you're at home but turn them off when you leave because ceiling fans only move air around and that wastes electricty.
