From a news release issued by the Public Service Commission:

MADISON – – Utility bills can soar with rising temperatures. To stay cool this summer while conserving energy and keeping costs down, the Public Service Commission of Wisconsin (PSC) offers these easy, low-cost steps:

 Use cold water for doing laundry and air dry your clothes on clotheslines.
 Wash dishes with cold water and air dry.
 Turn off lights when leaving a room.
 Check the weather-stripping and caulking for leaks around doors and windows.
 Use a microwave oven or cook outside instead of using the stove or oven.
 Minimize the amount of time your refrigerator and freezer doors are open.
 Use natural lighting and compact fluorescent light bulbs. Ninety percent of the energy used by an incandescent bulb makes heat.
