One of the energy hogs in your home is the refrigerator. Set the fridge section to no lower than 37F and the freezer section to no lower than 3F. Don't overpack the freezer as it causes it to work harder.
Viridian's rates in Illinois this month are:
variable 20+% green - only 5.99 cents/kWh
variable 100% green - only 7.49 cents/kWh
You can switch to the variable rate at no cost. There is also no cost to change to another supplier or to a fixed rate later. The price of the energy can, however, change. Regardless, savings over a 12 month period may be around 10% over the utility rate. And just think - You are greening the planet at the same time.
FIXED RATES?
