From the Jackson Energy Authority –

With the sweltering temperatures outside, the Tennessee Valley Authority is asking customers to help lower the heavy demand on the electric system during the current heat wave by conserving energy.
There are several ways customers can help:

~Set your thermostat no lower than 78 degrees. Use ceiling fans to keep air flowing when you’re at home.

~Remember to turn a fan off when you leave the room. Fans cool people, not rooms.

~Put off chores that involve electric appliances, such as dishwashing and laundry, during peak power times (10 a.m. – 8 p.m.)

~Use the microwave instead of the oven for cooking your meals.

~Turn off lights when you leave the room and unplug unused electronics.

~Keep garage doors closed as much as possible.

~Keep curtains and blinds closed on the sunny side of your home to block out some of the heat.
