  • Dirty Secret Behind Wind Turbines, They Need Lots Of Oil

    Mar 03, 2017Dirty Secret Behind Wind Turbines, They Need Lots Of Oil. Offshore wind turbines may generate green energy, but they use a lot more oil than proponents like to admit. Just installing the foundation of a single offshore turbine can consume 18,857 barrels of marine fuel during construction, according to calculations published by Forbes Wednesday.

  • National Wind Watch

    Wind power has a very low "capacity credit," its ability to replace other sources of power. For example, in the U.K., which boasts of being the windiest country in Europe, the Royal Academy of Engineering projects that 25,000 MW of wind power will reduce the need for conventional power capacity by 4,000 MW, a 16% capacity credit.

  • WIND TURBINE POWER, ENERGY, AND TORQUE

    At standard conditions, the power in 1 m2 of wind with a speed of 5 m/s is 0.647(5)3 = 81 W. The power in the same 1 m2 of area when the wind speed is 10 m/s is 647 W. This illustrates two basic features of wind power. One is that wind power is rather diffuse. It requires a substantial area of wind turbine to capture a significant amount of
