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.
