A giant plane for giant wind turbines

May 22, 2025 By EarthWise Leave a Comment

Wind turbines have been getting bigger all the time. Larger turbines have real advantages. They can operate at lower speeds so they can be deployed in more places. They capture more wind, so they make more power. Large wind turbines can have blades more than 200 feet long and even larger ones are on the way. An offshore wind farm in China has turbines with 400-foot blades.

Giant wind turbines face a thorny problem: getting the blades to where they are to be installed. The enormous blades can’t be easily shipped across aging roads and bridges. Tunnels are too narrow, bridges are too low, and roads can be too tight to allow turns when transporting these massive turbine parts. Some developers have actually had to build special roads for wind projects.

For nearly a decade, a Boulder Colorado company called Radia has been working on what would be the world’s largest plane. The WindRunner aircraft would have a dozen times the cargo volume of a Boeing 747. The WindRunner will be 356 feet long and 79 feet tall. While its primary purpose would be transporting wind turbine blades, the plane could also be used to aid the military or businesses that are thinking really big. Product developers often don’t even try to invent really big things because there is no way to transport them. Radia expects the WindRunner to be rolled out before the end of the decade.

The wind industry is currently facing strong opposition from the Trump administration, but wind energy is not going away and bigger and better wind turbines will ultimately be built and will have to be transported.

Offshore wind in Massachusetts

February 1, 2024 By EarthWise Leave a Comment

On January 2nd, the first large offshore wind farm in New England started producing electricity when its first turbine came online. The Vineyard Wind project, located off the coast of Martha’s Vineyard, will by the end of the year have a total of 62 turbines with a capacity of 800 megawatts, enough electricity to power 400,000 homes.

Power finally flowing from Vineyard Wind is an important milestone for an industry that has struggled to get going. It is the second utility-scale offshore wind farm in the U.S. to begin generating electricity. The South Fork Wind project off the coast of New York began producing power in December. That project will eventually produce 132 megawatts of electric power.

The offshore wind industry in the U.S. has faced some difficulties in recent times. A combination of rising costs, high interest rates, supply chain delays, and incidents of local opposition have created headwinds. Developers for several large planned windfarms in the northeast have terminated contracts because of inflation and high interest rates. The second phase of Empire Wind, located southeast of Long Island, has been at least temporarily shelved awaiting more favorable contract terms.

To fight climate change, many Eastern states are hoping to install dozens of large wind farms in the Atlantic that can generate electricity without emitting greenhouse gases. But as a result of the recent project cancellations, analysts are now projecting that U.S. offshore wind capacity in 2030 will likely be about a third less than previously predicted.

So far, the United States remains far behind Europe, which has already installed more than 32,000 megawatts of wind capacity in its waters.

More Offshore Wind Proposed For New Jersey | Earth Wise

September 13, 2023 By EarthWise Leave a Comment

There have been three offshore wind projects previously approved by utility regulators in New Jersey. New Jersey is vying to become an East Coast leader in the fast-growing offshore wind industry and now developers have proposed four new projects off the New Jersey Shore.

Two of the projects would be located far out to sea where they would not be visible at all from the shore. One of them, called Community Offshore Wind, would be built 37 miles offshore from Long Beach Island. It aims to generate enough electricity to power 500,000 homes.

A second project, called Leading Light Wind, would be located 40 miles off Long Beach Island and would consist of up to 100 turbines that would generate enough electricity to power 1 million homes.

The two companies that are building the already-approved Atlantic Shores Wind Farm have submitted a bid for a new project located 10 to 20 miles offshore. In addition, a fourth application to the New Jersey Board of Public Utilities has also been submitted, but there is yet no public information about it.

Existing offshore projects have drawn intense opposition from homeowners in part because they are close enough to the Atlantic City and Ocean City shorelines to be seen by beachgoers, albeit as tiny objects on the horizon. The new proposed projects located far offshore would not have this problem.

The new projects can take advantage of existing federal tax credits, but the bidders say they will not seek the tax breaks from New Jersey that the earlier project received as they have also been the subject of legal challenges by opponents of offshore wind.

Floating Offshore Wind | Earth Wise

April 21, 2022 By EarthWise Leave a Comment

According to a new report by the Global Wind Energy Council, floating offshore wind technology is on track to grow from a miniscule market to a substantial contribution to the world’s energy supply over the next decade. Furthermore, the United States represents one of the countries with the greatest potential.

Wind power is stronger and steadier in the ocean than on land, so the use of offshore wind is rapidly expanding. However, because most installations are based on fixed structures attached to the sea bottom, they cannot be installed in very deep or complex seabed locations.

Floating offshore wind is based on structures that are anchored to the seabed only by means of flexible anchors, chains, or steel cables. Apart from making it feasible to place wind turbines in deeper and more distant locations, floating turbines and platforms can also be built and assembled on land and then towed to the offshore installation site.

The floating offshore wind industry is currently in a pre-commercial phase but has great potential. Many offshore locations with great potential in terms of their wind resources are unsuitable for conventional installations either because of the depth of the seabed or its complex structure. This is particularly true of the waters off the coasts of California, Oregon, and the Gulf Coast, which otherwise offer excellent wind resources.

There are many issues to deal with in expanding the use of floating offshore wind, including transporting the power to shore and the ability of the local power grids to handle the incoming power. On the other hand, distantly placed floating offshore wind reduces environmental concerns and eliminates issues associated with the visual impact of wind farms for coastal residents.

Is U.S. Offshore Wind Finally Happening? | Earth Wise

March 26, 2021 By EarthWise Leave a Comment

Offshore wind capacity has been growing rapidly in recent years, especially in Europe and China. Globally, there is now more than 30 GW of offshore wind and industry experts predict that there will be well over 200 GW of installed capacity by 2030.

Meanwhile, the U.S. has only two small pilot projects, one with five turbines off Rhode Island and another with two turbines off Virginia. But after many years of battles with determined opponents, false starts, regulatory struggles, and other hurdles, the U.S. offshore wind industry appears to be poised to take off.

A combination of significant commitments by power companies to purchase offshore wind power, strong support by the Biden administration, and billions of dollars in investments is creating the new-found momentum.

New York, New Jersey, Virginia, Massachusetts, Connecticut, Rhode Island, and Maryland have collectively committed to buying 30 GW of offshore electricity by 2035. (That’s enough to power roughly 20 million homes).

Among the first major offshore installations to be completed in the next few years in the U.S. will be Vineyard Wind, 15 miles off of Martha’s Vineyard, another wind farm 60 miles east of New York’s Montauk Point, a third fifteen miles off Atlantic City, New Jersey, and a fourth off the Virginia Coast.

Offshore wind projects will create nearly 40,000 jobs just in the New York-New Jersey area over the next ten years. There is still some opposition from elements of the commercial fishing industry and from some coastal residents. However, with state and federal governments committed to reducing carbon emissions and rapidly reducing regulatory barriers, and with the price of offshore wind continuing to get lower and lower, most observers agree that the U.S. offshore wind industry is finally on the verge of really getting going.

Surging Wind Power In The U.S.

June 16, 2017 By EarthWise

So far, it has been a big year for the U.S. wind industry, which experienced its fastest first-quarter growth since 2009. In total, about 2,000 megawatts of new capacity was installed, enough to power about 500,000 homes. With this addition, wind now produces 5 1/2% of the country’s electricity.
