  •  According to New Jersey's Clean Energy ... (3+ / 0-)

    program, the average NJ residence uses 8400 kWh per year, not 58,000 kWh, 7x less. The average U.S. home consumes about 10,000 kWh annually.

    7 x 327 = 2289 homes.

    8440 x 2289 = 19,227, 600 kWh

    19,000,000 divided by 10,000 = 1900 homes.

    As for the wind turbines, they usually do generate - depending on wind speed, etc. - about one-third of rated capacity. In the earliest years (2005-2006), the Jersey-Atlantic site produced 21 million and 20 million kWh respectively.

    •  Energy vs Electricity (0+ / 0-)

      I believe the discrepancy is because the 58,000 KWh is the total energy the average NJ house uses, but 8400 KWh is the total electricity. I live in NY, effectively the same as NJ, and before I superinsulated my house it did use about 7x as much energy (actually somewhat more) for heating air & water as it did for electrical appliances & lighting.

      The windfarm article does say "energy for 2000 homes", but of course windmills produce only electricity. So it really should say "electricity for 2000 homes", since that's only a small fraction of the energy required for a NJ home, about 14%.
