Wind Turbines are NOT Green. Can you prove this wrong?

This incredible analysis only considers the environmental effects of the base, not the tower or blades. Heavens, we can’t even manufacture turbines with electricity produced from turbines, if we force fossil fuel plants to close b/c turbines are not energy dense and reliable enough…
The base of this 2.5 megawatt turbine …used 45 tons of rebar and 630 yards of cement.  This computes in barrels of oil and in tons of CO2 for each base:
For the Concrete
478.8 Barrels of oil in 630 yards of concrete.
409.5 Tons of CO2 released for 630 yards of concrete.
For the Rebar
Taking a conservative 3 barrels of oil per ton the rebar would require 135 barrels of oil for the base of the 2.5 MW Turbine.
89 tons of C02  released for 45 tons of steel for the base.
All Together
The concrete and steel together for one base use 
613 barrels of oil for each base alone. 
Each base release 498 tons of CO2
(A barrel of oil is 42 gallons)

 

…With various iron making processes, iron has a range of Btus per ton.   Converted to barrels of oil the range is 2.17 to 4.83 barrels of oil per ton of rebar. 

Taking a conservative 3 barrels of oil per ton the rebar would require 135 barrels of oil for the base of the 2.5 MW Turbine….

CEMENT ENERGY 
         Multiply 1.10231 to convert tonnes to tons
            One yard of concrete equals two tons
                Two tons equals 1.81437 tonnes
              4426832.62 Btus in a yard of concrete
                 5800000 Btus per barrel of oil
              0.76 barrels of oil in a yard of concrete
            32.06 gallons of oil in a yard of concrete
              0.65 tons of CO2 per yard of concrete
         478.8 Barrels of oil in 630 yards of concrete
          20195.52 Gallons of oil in 630 yards of concrete
              409.5 Tons of CO2 per 630 yards of concrete
