Revolution Wind installs first turbine

September 27, 2024 By EarthWise Leave a Comment

Revolution Wind installs its first wind turbine

Revolution Wind is an offshore wind farm being built by Rhode Island and Connecticut and is the first multi-state offshore wind farm in the United States.  Once completed, it will deliver 400 MW of power to Rhode Island and 304 MW of power to Connecticut.

Revolution Wind is a 50/50 partnership between Ørsted, the Danish multinational energy company, and Eversource, a major New England utility company.  The wind farm is located about 15 miles south of the Rhode Island coast and 32 miles southeast of Connecticut.  It is fairly close to the recently completed South Fork Wind, the first completed utility-scale offshore windfarm in the U.S. and was built by the same partnership.

The first Revolution Wind turbine was installed at the end of August and construction continues with the installation of foundations for the 65 turbines that will comprise the project.  More than three-quarters of the units were in place by the beginning of September.  Ships have also arrived on scene for cable-laying operations for the wind farm.  Onshore construction continues in North Kingstown, Rhode Island, on the project’s transmission system.  The turbines for the project are being assembled by local union labor in New London, Connecticut. 

Commercial operations at Revolution Wind will not begin until 2026.  Construction of the electrical substation necessary to connect the project to the regional electric grid is taking place on the site of a decommissioned naval air station and it is a time-consuming project because of the presence of buried waste and soil contamination.  The construction of the offshore wind farm itself will be completed in 2025.

Resurrecting The Tasmanian Tiger | Earth Wise

Company plans to resurrect the Tasmanian Tiger

Tasmanian tigers earned their nickname because of the stripes along their back, but they were not felines.  In fact, they were carnivorous marsupials, the type of Australian mammal that raises its young in a pouch.

Tasmanian tigers, also known as thylacines, were once native to the Australian mainland, as well as the islands of Tasmania and New Guinea.  Dog-like in appearance, Tasmanian tigers were extensively hunted after European colonization.  The last known Tasmanian tiger died in captivity in 1936.

Nearly 100 years after its extinction, the Tasmanian tiger may live once again.  Scientists in Australia and the United States have launched an ambitious multimillion dollar de-extinction project to genetically resurrect the Tasmanian tiger.

In order to bring back the animal, researchers will have to take stem cells from a living species with similar DNA – like the fat-tailed dunnart – and use gene editing techniques to turn them into “Tasmanian tiger” cells – or the closest approximation possible.  The team will need new assisted reproductive technologies to use the stem cells to make an embryo, which will then have to be transferred into an artificial womb or a dunnart surrogate to gestate.  The research team is optimistic that there could be a hybrid baby Tasmanian tiger in 10 years. 

The ambitious project is a partnership between scientists at the University of Melbourne and the Texas-based company Colossal Biosciences.  This is the second de-extinction undertaking by Colossal Biosciences, which announced last year it planned to use its technology to recreate the woolly mammoth, and return it to the Arctic tundra.

Cloudbursts And New York City

Cloudbursts are intense rainstorms that drop enormous amounts of water over a short period of time.  Climate change is expected to make cloudbursts occur more frequently.  Cities around the world are looking for better ways to cope with weather phenomena like cloudbursts.
