The Grobo is extremely energy efficient due to it's size and LED design.

It consumes approximately the same power as a typical ceiling fan, which is around $5 per month. Please be advised, however, this can change based on your location's rates. 

Rough estimates have the unit using about 1.4kWh per day to operate.
