Cut your electricity bill.

You may not be able to pick up the phone and get batter rates here (as these companies tend to be local monopolies), but you can go out and purchase a smart thermostat.

With these thermostats (some even have an app!), you can control when your heat or A/C are turned on and off.

This can save you a lot of money per month.

If nobody is home from 9am - 6 pm, why should your heat or A/C be on the whole day? Turn it on from your mobile phone while you are in traffic on the way home.
