Sustainable Housing - Turbines and windpower

The Dallas Observer published a great article this week on North Dallas homeowner Paul Westbrook who incorporated a styrofoam core into the construction of his home to reduce his heating and cooling bills. His neighbors pay as much as $500 in monthly electric bills, whereas he pays $70 to $100! His most recent enhancement to the property is the installation of a turbine which harnesses windpower which will contribute to reducing energy costs even more.
