Business Week highlighted in their Oct. 11-17 magazine the cost for green energy. Some green energy sources such as wind energy has become almost so competitive with coal that it will start making sense to use more wind energy. Some other sources while reliable, are having a hard time finding banks willing to lend money. The chart below highlights the costs of producing electricity based on dollars per kilowatt-hour (range from low to high cost).
Coal- $56-63
Geothermal- $52-112
Wind (on shore)- $62-119
Biomass- $86-189
Wind (off shore)- $143-260
Tidal- $194-453
Solar (c-Si PV)- $226-424
Solar (thermal)- $238-313
