No matter where you live, energy costs are a concern. Some places use more energy during the winter. Other places, like Arizona, use a lot more during summer.
While costs might be low for the moment, those numbers can change on a dime. With constantly rising or falling numbers, how's anyone supposed to figure out if they're wasting money on electricity?
Luckily, a site exists to estimate exactly that. The Department of Energy developed a site that helps you to audit your home's power usage and cut your utility bills.
Figuring out where you're spending more or less money can be very valuable.
