Ocean Wind Energy (continued)
zLong fetch (distance) of
unhindered wind increases speed and available energy beyond land
installations
zOffshore
wind turbines diminish public outcry against wind turbines (low
visibility, monopod supports)
zTurbines are typically placed on
concrete supports in groups; rotors are often 80 m in
diameter
zTurbines
are also placed along a coast on the foreshore area to intercept
the prevailing wind from over the ocean
zMust avoid bird
migration routes; turbine ~20 to 30 rpm
