Part of saving money on your energy bill is identifying your high spending habits—which also includes knowing which appliances and electronics are costing you extra. The Belkin Conserve Insight Energy Use Monitor is a simple way to discover how much your TV or microwave really racks up on a yearly or monthly basis, plus it highlights each product’s carbon footprint so you’re aware of how much energy it’s eating. The real money-saver comes from the tracking feature, which observes your device usage over time and projects the dollar impact each has on your electric bill. With the option to set your specific energy rate, and available at a relatively low price point, there’s no reason you shouldn’t grab up one of these go-green gadgets today. Available on Amazon; 34.
