Offshore wind farms in the United States | Block Island leads the way

Block Island Wind Farm - the first of many offshore wind farms in the United States

The Block Island Wind Farm

The United States' 1st operational offshore wind farm is the Block Island Wind Farm, developed by the company Deepwater Wind (acquired by Ørsted in 2018). The 30 MW Block Island Wind Farm is 4 miles off the coast of Block Island, Rhode Island; and began operating in 2016. [CLICK FOR MORE INFO. ON THE>>> Block Island Wind Farm from Inside Climate News].

Ørsted is the current owner of Block Island Wind Farm and is the largest energy company in Denmark. Ørsted has built the most offshore wind farms of any company globally. Ørsted has built both the Anholt Offshore Wind Farm in Denmark and the London Array Offshore Wind Farm, both of which are featured in Green City Times.

Block Island is now powered entirely by wind (instead of polluting diesel generators). Based on the success of the Block Island Wind Farm, there is about 30 GW of offshore wind projects in various stages of development off the East Coast of the United States (as of 2020); a few of which should be completed by 2023-2025. In addition, there are other proposed (smaller scale, but as of yet not in development) offshore wind projects in the U.S., such as proposed offshore wind projects in the Great Lakes (as described in this article by Inside Climate News).

U.S. Offshore Wind Farms - Proposed and in Development

                              Among the new developments/ proposed developments for offshore wind farms off the US east coast is the 1.1 GW Ocean Wind offshore wind farm off the coast of New Jersey (also being developed by Ørsted US Offshore Wind) - with a goal of becoming fully operational in 2024.

Large US offshore wind farm projects also include:

Read a more detailed description of the Vineyard offshore wind farm, among other large-scale offshore wind projects off the East Coast, from The Boston Globe.

Other major offshore wind farm projects off the East Coast of the U.S. include more projects off New York, New Jersey, Rhode Island, and Massachusetts; as well as Maryland, Connecticut, Delaware, Virginia, and other states on the East Coast. All of these projects each create hundreds of jobs for the local economy, many of which are permanent; while also creating a highly efficient, clean source of energy.

According to the U.S. Department of Energy, more than 25 offshore wind projects with a generating capacity of 24 gigawatts are now being planned, mainly off the U.S. Northeast and mid-Atlantic coasts. And although some of these projects may not be built, and only one commercial offshore wind farm has actually been constructed —the tiny, five-turbine “Block Island Wind” project off Rhode Island — analysts say that U.S. offshore wind is expected to enjoy significant growth in the coming decade. - quote from

Block Island vs. European Offshore Wind Farms

The Block Island Offshore Wind Farm is just 30 MW; with a total of five 6 MW turbines. This offshore wind farm serves to provide power to the relatively tiny population (>2000 p.) of the Block Island community and Block Island resorts, part of Rhode Island. All combined, the Block Island Wind Farm can potentially provide power for up to 17,000 homes.

London Array Offshore Wind Farm

In comparison, the 630 MW London Array offshore wind farm powers half a million UK homes every year. (see: London array). The London Array has 175 turbines, with each wind turbine at a little more than 1/2 of the MW (3.6 MW turbines compared to 6 MW turbines) of those on the Block Island Wind Farm. The United States has a way to go to catch up with Northern Europe as far as developing offshore wind farms; and as of yet, the U.S. has only developed a tiny fraction of this renewable energy source's potential.

Scotland recently powered most of its country with wind energy. Scotland also boasts the Western world's first operational floating offshore wind turbines, pioneering floating offshore wind turbine projects. Denmark is also one of a few countries that have used offshore wind energy (along with onshore) as their main power source, albeit for short periods of time (see: leading countries in wind energy). GE recently unveiled a 12 MW offshore wind turbine - the Haliade-X - which has been developed and made commercial for use in the above-mentioned Ocean Wind Farm, the Vineyard Wind project (as described in this article by The Boston Globe), and other U.S. and European offshore wind farms.

***UPDATE as of the end of 2018:

After buying the wind farm in 2018, the new Danish owners - Ørsted —[one of the] largest owners and developers of wind farms in the world — took over ownership from Deepwater Wind.
Deepwater Wind still operates the wind farm, and released this statement - Ørsted plans to grow Deepwater Wind’s presence in the coming years, making Providence and Boston the two major [new] hubs of the company’s U.S. offshore wind."    FROM:
