  • 1

    what is the foundation of the onshore turbines

    under the ground

  • 2

    the base is under the water and it cannot be seen. the base is floating but a sufficient mass to support the turbine weight and all the forces exerted on it and to hold it upright

    offshore turbines

    pic

  • 4

    one of the varieties of vertical axis wind turbines

    egg beater style Darrieus Model

  • 5

    this turbines are unidirectional meaning they don't need to be adjusted the point in to the wind to operate

    vertical axis turbines

  • 6

    have three blades and operate "upwind" with the turbine pivoting at the top of the tower so the blades face into the wind

    horizontal axis turbines

  • 7

    two types of wind turbines

    horizontal axis turbines and vertical axis turbines

  • 8

    type of wind energy 3

    utility-scale wind energy offshore wind energy small-scale or distributed wind energy

  • 9

    this type of wind energy is the opposite of the others as this wind turbines are smaller in physical size and are used to meet the energy demands of a specific site or local area

    small scale or distributed wind energy

  • 10

    these are generally utility-scale wind energy projects that are planned in the waters off coastal areas

    offshore wind energy

  • 11

    they can generate tremendous power near larger cities since the wind blows more consistently and strongly in offshore areas than in land
