The Treehugger website is running some good news on an ultra-efficient model home.
This house has the conveniences of a modern house, but consumes only 800Whr on average per day. Compare this to a typical U.S. suburban house that uses 45 kilowatt hours (kWh) per day. How is this reduction possible? It’s through the strategic use of ultra-efficient appliances, daylighting, and green design principles for temperature control and ventilation.
The house also automatically turns off computer peripherals when not in use.
