My friends across the pond at Ovo Energy have partnered with Stuff Parents Need today to bring you a sobering look at just how much money you might be throwing away, even in your sleep, by leaving appliances plugged in and/or turned on. Before we had kids, Tim and I were actually pretty good about turning off most things before heading to bed. Not so much, anymore. But this is a good wake up call for me. Honestly, this is a pretty simple way to save some money! And just to help you with conversions, 1 British pound = roughly $1.50 .Brought to you by Ovo Energy the cheaper, greener and simpler energy supplier.
