Are Offshore Wind Turbines the Answer to Clean Energy?

In the continuing effort to switch to renewable energy, offshore wind turbines, whose positive effects are being stressed in many studies, may be the solution.

The clean energy debate swirls amidst rising oil prices and tragedies like the Upper Big Branch Mine disaster and BP's Gulf oil spill. Offshore holds new meaning for many these days, but when you're talking about wind turbines, the picture changes completely, and around the world many are turning to offshore wind turbines as the answer.

Used in Denmark since 1990, the potential for large-scale offshore wind farms is huge. One study suggests 130 turbines alone could supply 3,000 megawatts, a far greater output than any power source we currently have today.

As with any energy source, however, controversy surrounds this project. Fortunately, with the positive results of research studies, some of it seems to be dying out. The concern for marine life has been documented to be wholly unfounded in study after study. Many environmental groups suggest it may even help marine life, as it will provide them with a safe haven to repopulate after over-fishing in recent years. Naturally, extensive studies will have to be completed in any area where wind turbines might be placed.

The bigger controversy, however, is the cost of energy from any potential wind farm. The wind farms themselves, as well as the consumers who would pay the final cost, are raising concerns about pricing. The New York State Energy Research and Development Authority, however, authored one study that suggested an eventual reduction in payments to the tune of $305 million per year.

To date, more studies are being launched in the United States to find areas for offshore wind turbines and to analyze the sustainability and costs of such projects. The first proposed project, located on Nantucket Sound, has finally won approval. With the 2020 deadline ticking ever nearer for utility companies to obtain 15 percent of their energy from renewable sources, this looks like one of the most viable options for coastal areas.
