Today I was trying to find more the ongoing offshore wind generation project in North America and I found this website. It has some information about the current projects and the locations. Plus it has some basic information about the offshore wind turbine structures that I was very curious about like subsidization of offshore wind and deep water foundations. It is worthwhile to know the potential energy produced from the wind is directly proportional to the cube of the wind speed, meaning a few mile an hour increase in wind speed would produce a significantly larger amount of electricity. For instance, a turbine at a site with an average wind speed of 16 mph would produce 50% more electricity than at a site with the exact same turbine with average wind speeds of 14 mph. The power of the wind is significantly less on land: “The wind is slowed dramatically by friction as it brushes the ground and vegetation, it may not feel very windy at ground level. Yet the power in the wind may be five times greater at the height of a 40-story building (the height of the blade tip on a large, modern wind turbine) than the breeze on your face.” Lager turbines are more economically feasible.

For instance if wind averaged 18 mph, in February of 2005, a 3 MW wind turbine would deliver electricity at a cost of $.059 per kWh while a 5 MW turbine would deliver electricity at $.036 per kWh, or 40% cheaper electricity. Offshore wind can be significantly more marketable.  (From the website)
