The name of the game for homes today is energy conservation and the next thing you would need are devices or gadgets that can help you monitor your power consumption. For that requirement, here are two devices worth considering.

The Tweet-a-Watt, a power meter that automatically publishes your power usage wirelessly via Twitter for friends and followers to see. The Power-Hog took second place with its own unique “metering” concept: it’s an energy-consumption piggy bank that teaches kids the monetary value of electricity.

Both gizmos are indication of the growing “eco-metering” market—perhaps soon-to-be mandatory in some countries. Rising to meet the overwhelming demand, other energy-savvy gadgets include the Home Joule, an i-device which plugs into a power outlet and displays energy usage data transmitted wirelessly from your energy meter. Combined with information from the energy company, including the real-time price of energy, the changing color-coded monitor tells you when you might want to reduce your levels of consumption to keep costs down.
