MidAmerican Energy has issued a "Peak Alert" in Iowa because of the hot, humid weather.
The utility is suggesting customers raise the thermostat at home a degree or two.
Spokesperson Tina Pottoff tells WHO Radio News setting your thermostat a few degrees higher can make a big difference on your next bill – reducing electrical usage 3 to 5 percent for each degree. She says if you are not at home during the day, close the house and turn off the air conditioner.
MidAmerican Energy also recommends customers close drapes to shut out sunlight during the day and using big appliances early or late in the day.
The Peak Alert will also be in effect tomorrow (Friday).
