I received a post today from my electric company listing ways to save money on your electric bill. It list the common ones like use ceiling fans, close blinds and curtains, etc. Then I noticed this one:
Use a slow cooker when you can, since it uses less power than an electric stove top. When you do cook on the stove, use covered pans with well-fitting lids so contents cook faster. - See more at: http://energyinyourlife.com/know-unique-ways-save-power/#sthash.qawuwp8u.dpuf
Just another good reason to keep that slow cooker out!
