Gadgets that help you save energy (and money)

Getting a handle on your household energy consumption can benefit your wallet and the environment.

Your heating and cooling usage is an obvious target, but it's also important to monitor your gadgets and electronics gear. The average US home constantly leaks about 50 watts of power from products left in standby mode, according to Lawrence Berkeley National Laboratory. That's about five percent of the residential electricity use in the US. And for every watt of power we constantly draw per year, we pay about a dollar.

Below you'll find devices that help determine where you're losing your money and ensure you keep spending under control.

Saving money on heating & cooling

Black & Decker TLD100 thermal leak detector
You'll see big savings on your monthly energy bill when you stop heat and air conditioning from leaking out of your house. A thermal leak detector, like the Black& Decker TLD100 can show you where your home's leaks are. Once the device has read the ambient temperature, you can start checking around windows, door frames and other places air could be escaping. The light will change to red for warmer spots and blue for cooler spots. You can set the temperature tolerances to one, five or 10 degrees. - $28.70

The Nest Thermostat is smart enough to know when you're away. So if you forget, it can lower the temperature about two hours after you've left. It's continually monitoring your habits, so it can automatically adjust the temperature based on your needs. And, Nest lets you know when you're saving energy, rewarding you with a green leaf icon. Even small changes to your thermostat settings can impact your monthly energy bill. For instance, each degree above 68° F can add three percent to the amount of energy needed for heating, according to the Edison Electric Institute. - $249
