FIGURE 4.6 Average wind speeds, m/s, at 10 m height for 1988-1994 for Gulf of Mexico, Texas coast.

Over 1,000 MW have been installed in offshore wind farms in Europe, because in general wind speeds are higher and onshore land has a high value. The United States is considering offshore wind farms near Cape Cod, Massachusetts, and the Gulf Coast of Texas. Wind farm developers have expressed interest in offshore in the Great Lakes and on both coasts. A program for offshore wind resource assessment has began at NREL [20]. The maps will extend from coastal areas to 90 km offshore and have a horizontal resolution of 200 m. The final maps of wind speed and power will be for 50 m height, and the model data will be modified with data taken at sites on the coast and offshore.

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
