(Harrisburg) -- The state Public Utility Commission is reminding people to use energy wisely as high temperatures put a big demand on the midstate's electric grid.
The PUC recommends setting air conditioning thermostats to 78 degrees or warmer, and even turning it off altogether when no one's home.
Spokeswoman Denise McCracken says routine maintenance and common sense can save money, too.
"It's really important to make sure your air conditioner filters are clean and in good shape," McCracken says. "Other things you can do, turn off non-essential appliances and lights, and you can also postpone use of your appliances that produce a lot of heat, like your clothes dryer, until later in the evening."
McCracken says people using window air conditioning units should seal off rooms that don't need to be cooled.
She says thermal curtains can also be used to keep out sunlight and cool the interior of buildings.
