The 167-million dollar Quilt Block Wind Farm in southwestern Wisconsin is expected to produce enough electricity to power about 25-thousand homes.  Each of the 49 towers erected in Lafayette County generates about two megawatts.  Dairyland Power Cooperative has signed an agreement to buy the wind farm’s power for the next two decades.  Landowners will be paid about 23-million dollars to host the towers.  Dairyland says it made the agreement so it can diversify its sources for energy and become less carbon-intensive.
