If you've ever received a high energy bill, it might be time to learn how to read your meter, so that you can begin saving.

Explanation:

Every appliance and electronic device in your home adds to your bill. By calculating your own tab, you can find out which appliances are costing you much more than they should. This awareness can both lower your bill and reduce your carbon footprint at the same time.
