We’re wrestling with an energy disorder: We’re binging on electronics—cell phones, iPads, Blackberries, laptops—then crash dieting by installing LED fixtures and turning the thermostat to 68 degrees.

Are we ahead of the energy game? Only the energy monitors and meters know for sure.

These new tracking devices can gauge electricity usage of individual electronics ($20 to $30) or monitor whole house energy ($100 to $250). The TED 5000 Energy Monitor ($240) supplies real-time feedback that you can view remotely and graph by the second, minute, hour, day, and month.
