Global wind power capacity has increased more than fivefold over the past decade, leading to larger turbines, but low-level jets are one cause for concern. The effects of these strong, energetic wind flows depend on how high the wind flows are in relation to the turbines. In the Journal of Renewable and Sustainable Energy, researchers considered three different scenarios in which the LLJs were above, below, and in the middle of the turbine rotors.

A recent study found that 2 to 3 gigawatts of electricity from winds off the coast of Oregon could be carried by current transmission lines. That’s enough to power up to 1 million homes—a significant number since there are 1.5 million homes in Oregon. But just as significantly, it also means that delivering that power would not require much additional investment in new transmission infrastructure.
Iowa now generates more than 40% of its electricity from wind power. But wind-dominant electric grids aren’t designed to meet a typical, step-by-step blackout recovery after storms. Iowa State’s Hugo Villegas Pico will lead a team that will research how to orchestrate the restoration of wind-dominant grids.
A new interdisciplinary Cornell University research project is designed to unlock the power of wind energy by optimizing the spacing between wind turbines and wind turbine arrays to maximize power production.
PNNL has deployed (10/8/20) two research buoys in waters off the West Coast for the first time in deep water, supporting a U.S. Department of Energy and Bureau of Ocean Energy Management effort to gather measurements that support offshore wind locations and technologies.
With the growing role of renewables in the nation’s energy mix, Tulane University’s A. B. Freeman School of Business has launched a program to teach students how to bring renewable and sustainable energy projects from concept to completion.
As the climate of the planet is changing, many researchers are looking to more renewable energy sources. In the Journal of Sustainable and Renewable Energy, researchers investigate whether the power generated by solar and wind farms would differ between current and future climates. The researchers focused on sites in Australia where variable renewable generators are located or are likely to be located in the future based on the Australian Energy Market Operator’s system plan.
To meet the current and anticipated demand for offshore wind, we’re going to need marshalling ports, large waterside sites with the acreage and weight-carrying capacity necessary to assemble, house and deploy the huge wind turbines ready to ship out into the ocean. A new study from the University of Delaware has identified two prime east coast locations for marshalling ports on either side of the Delaware bay.
Florida is one of several states in the Southeast where wind energy is virtually nonexistent, which is one reason wind farms have not been an economically viable energy source in the region. But a new study from the FAMU-FSU College of Engineering shows how upcoming technological advances could make wind energy a hot commodity in the Sunshine State.
Could we create massive sulfuric acid clouds that limit global warming and help meet the 2015 Paris international climate goals, while reducing unintended impacts? Yes, in theory, according to a Rutgers co-authored study in the journal Earth System Dynamics. Spraying sulfur dioxide into the upper atmosphere at different locations, to form sulfuric acid clouds that block some solar radiation, could be adjusted every year to keep global warming at levels set in the Paris goals. Such technology is known as geoengineering or climate intervention.
