39. Who’s House Bush or Gore HOUSE 1: 4 bed rooms, single story using native limestone and position to absorb sunlight to heat the 4,000 square foot residence. Geothermal heat pups circulate water through pipes buried 300 ft deep in the ground. A 25,000 gallon underground system collects rainwater and grey water from the house and uses it to irrigate the landscaping of indigenous grasses, shrubs, flowers. This house consumes 25% of the energy of an average American Home

40. HOUSE 2: 20 room, 8 bathroom house consumes more electricity each month than the average American household uses in an ENTIRE year. In 2006 it used 221,000kWh. More than 20x the nation average. The average monthly bill 1,359. In this house 30,000 in combined electricity and natural gas bills for 2006. 20 room, 8 bathroom house consumes more electricity each month than the average American household uses in an ENTIRE year.

42. Practice Thorpeville is a rural community with a population of 8,000 homes. It gets its electricity from a small, coal burning power plant just outside of town. The power plant’s capacity is rated at 2 megawatts with the average home consuming 10,000kWh of electricity per year. Residents pay $.12 per kWh. A group of entrepreneurs is suggesting that the residents support a measure to install 10 wind turbines on existing farmland. Each wind turbine is $1.5 million dollars to purchase and operate for 20 years. The existing power plant runs 8,000 hours per year. A. How many KWh of electricity is the current plan capable of producing?
