No owls are not omnivores because they eat mice,lizards,and snakes.
5.3 Operating Expenditures for Offshore Wind There has been no indication that expected operating expenditures for offshore wind projects have shifted between 2010 and 2013. The OpEx baseline for 2013 was assumed to be $40/MWh, equivalent to $136/kW/yr, with a range extending from $20/MWh to $70/MWh.
3. The levelised cost of electricity from wind varies depending on the wind resource and project costs, but at good wind sites can be very competitive. The LCOE of typical new onshore wind farms in 2010 assuming a cost of capital of 10% was between USD 0.06 to USD 0.14/kWh.
