Nest Learning Thermostat, $249

Some green gadgets save power when they turn off automatically. The Nest Learning Thermostat, which works fine in an office environment, can save on your heating and cooling bills based on when you are not around. You train the thermostat by adjusting the temperature at the end of the day when you leave. There’s also a motion sensor that learns when no one is around. Entrepreneurs with a penchant for control can even adjust the temp using a mobile app.
