Bill Gates pushes carbon tax and lectures on energy efficiency while living in a 66,000 square foot mansion with 30,000 a month electric bill


According to Energy Monitoring Products analysis of Bill Gates home: “Not surprisingly, the typical monthly electric bill is also expensive — it averages $30000.”

Bill Gates House – Lake Washington, WA: “When Bill Gates began building his new home on Lake Washington near Seattle, expectations for the dream house ran high. After seven years of construction, the 45,000-sq-ft residence has been appraised at more than $53 million. Not surprisingly, the typical monthly electric bill is also expensive — it averages$30,000.

Because of this expense, Gates needed a way to monitor and track his electrical use down to the subpanel level. Now, thanks to the installation of a full-featured automatic meter reading hardware and software system (E-Mon, Langhorne, PA.), Gates knows exactly what the electrons he buys are doing — anytime, day or night.

As one might expect from the co-founder of Microsoft®, Gates built a compound full of futuristic electronic gadgetry. Visitors wear small electronic pins coded with their preference for room temperature, visual art, music, television programs and movies. Computers track the pins as visitors travel from room to room. All floors, driveways and walkways at the Gates residence are heated, and a 10-car subterranean garage electronically transforms into a basketball court. Automated security systems and hidden cameras cover every inch of the grounds, and floor sensors track visitors to within six inches of their location.

More than 100 electricians were involved in the installation of these systems. Many miles of communication cable — mostly fiber optic — connect computer servers throughout the house, yet no electrical outlets are visable. Operating and maintaining these electrical systems is a huge job, but the E-Mon system helps by providing current energy usage data. The system hardware in Gates’ basement consists of a multiple meter unit (MMU) containing eight E-Mon D-Mon submeters and a single IDR data recorder.

The recorder digitizes the metered electrical readings for use by the E-Mon’s meter reading software.(over)For more information, contact us at (800) 334-3666or via e-mail at [email protected]© 2006 E-Mon
