Concrete is considered the 3rd largest CO2 emitter, accounting for 4 to 8% of the world's CO2. A typical wind turbine uses approximately 550 tons of concrete. The production of 1 m³ of concrete requires 2,775 MJ of energy. Most of this energy comes from oil (90 barrels or so per turbine base).
* Note all the steel also required.
 The remote locations add to the huge cost and emissions, and the massive expense of connecting them to the grid.
 One might argue that their life expectancy ensures they cannot pay back for the emissions produced to install them.
