US Offshore Wind Energy Potential Is Staggering

The Lake Erie Energy Development Corporation recently wrote a piece highlighting the potential for offshore wind development in the US, specifically, in the midwest: The simple message? “The potential for offshore wind power generation in the U.S. is staggering.”

And the figures presented in the opening paragraph back this up: The US has a projected 4,223 GW worth of offshore wind generating potential — with 50 GW from the Ohio waters of Lake Erie alone.

The Lake Erie Energy Development Corporation was founded in 2009 to initially build wind turbines in Lake Erie, before desiring to turn its attention towards stimulating “an entire offshore freshwater wind industry.” And they make a strong case: As they write, “offshore wind offers a viable, untapped opportunity for large-scale clean energy projects that produce zero emissions in operation, consume no water, and displace the generation from some of our nation’s dirtiest power plants.”

But as Lake Erie notes, “the U.S. lags woefully behind the rest of the world in offshore wind power generation.”

One need only cast their eyes over the last few months of offshore wind energy news here at CleanTechnica, to see how thoroughly Europe figures in the industry. Danish juggernaut DONG Energy alone claims to have built more offshore wind farms than any other company worldwide, and a quick look at its installations show these clumped heavily in the west of Europe.

Lake Erie claims that Europe has at least 80 offshore projects in operation or under construction, compared to the US, where “offshore wind development is in its infant stages”.


Five innovations that could cut the cost of offshore wind

The expense is largely down to the difficulty of installing and maintaining large wind turbines able to withstand the elements.

This week the Royal Society has published a special journal issue devoted to offshore innovation. It has 16 papers covering everything from designing better turbines using computers and miniature models to cutting the cost of installation and maintenance through remote sensing. Here are five ideas from the special issue that caught our eye.

Screw-in turbine foundations
Good vibrations
Tiny models
Vertical axis floating turbines
Machine learning

DONG Energy - Wikipedia explains the source of that company's name: the acronym of Dansk Olie og Naturgas (Danish Oil and Natural Gas).

Another Legal Victory for America’s First Offshore Wind Project - rather difficult for me to think of a good summary of that latest round of litigation.

Cape Wind is currently in its financing and final commercial contracting stage. Cape Wind will complete its financing soon and construction will begin in 2015.

This year. Let's see if it does so.

And here's the question of the day: why not build onshore wind farms along the shoreline for a fraction of the cost instead? Same wind blowing as out over the water. Could it be for the same reason offshore east coast wind farms have been delayed for many years and why much of the EU wind power is generated offshore: NYMBYism. Texas built the first offshore wind test facility in the country despite the press touting east coast progress...progress that as of yet does not include even one offshore turbine.

And thanks to Texas developing more wind power then the next two states combined and providing the cheapest alternative energy in the country the plans for Texas offshore wind have been put on hold. Turns out that even though we can build such offshore farms cheaper than any other state (thanks to the oil patch infrastructure and virtually no NYMBYism from our coastal residents) they still can't compete with our onshore wind projects.

Thanks to cheaper electricity and NG a number of European manufacturers are relocating to S Texas. Just as a great many other businesses have relocated here.

New wind farm in service off the British coast

Unread postby AdamB » Thu 30 Nov 2017, 22:51:20

Norwegian energy company Statoil said Wednesday its Dudgeon wind farm off the British coast is now feeding the grid from its 67 wind turbines. The Dudgeon wind farm is about 25 miles off the coast of Norfolk. Its turbines, with a combined capacity of 402 megawatts, can meet the energy demands of around 410,000 average households at its peak. The Norwegian company, one of the main energy suppliers to the European market, said Dudgeon is part of its efforts to add more green components to its portfolio. "As part of our strategy to develop from an oil and gas company to a broad energy major, Statoil will grow significantly in profitable renewable energy, with an ambition to invest around $12 billion towards 2030," CEO Eldar Sætre said in a statement. Statoil placed the last of the 67 turbines at the Dudgeon wind farm
