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.Read more
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.Read more
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.Read more
World’s forests are growing younger, U.S. wind plant performance changes with age, and fungi food choices opens the door to better methods for producing bio-based productsRead more
Generating power through wind or solar energy is dependent on the abundance of the right weather conditions, making finding the optimal strategy for storage crucial to the future of sustainable energy usage. Research published in the Journal of Renewable and Sustainable Energy identifies key indicators that will help achieve balance between green energy storage capacity and harvesting capability and determine the energy potential of a region.Read more
The United States could generate 20% of its electricity from wind within 10 years, without requiring any additional land, according to Cornell University research published in Nature Scientific Reports.Read more
The wind over deep-sea waters offers the potential to become one of the country’s largest renewable energy sources.
University of Texas at Dallas researcher Dr. Todd Griffith has spent years working on an offshore turbine design that can convert those deep-ocean winds into electricity. Recently, Griffith received a $3.3 million grant from the U.S. Department of Energy to take his technology to the next level. The Advanced Research Projects Agency-Energy (ARPA-E) award provides support for his team to design and build a prototype for a floating offshore wind turbine.
The new grant was part of $26 million in funding from ARPA-E for 13 projects to accelerate floating offshore wind turbine technologies through the Aerodynamic Turbines, Lighter and Afloat, with Nautical Technologies and Integrated Servo-Control (ATLANTIS) program.
Much about the aerodynamic effects of larger wind farms remains poorly understood. New work in this week’s Journal of Renewable and Sustainably Energy looks to provide more insight in how the structures necessary for wind farms affect air flow. Using a two-scale coupled momentum balance method, researchers theoretically and computationally reconstructed conditions that large wind farms might face in the future, including the dampening effect that comes with spacing turbines close to one another.Read more
Wind energy holds great promise as a source of renewable energy, but some have wondered addressing climate change has taken precedence over conservation of biodiversity. Wind turbines, for example, kill some birds, and the fatality rate for bats is even higher. In the Journal of Renewable and Sustainable Energy, scientists report the results of a survey of stakeholders in the wind energy field about attitudes toward the relative emphasis on climate change versus biodiversity issues.Read more
Scientists at Berkeley Lab have designed an affordable ‘flow battery’ membrane that could accelerate renewable energy for the electrical grid.Read more
Wind energy pricing remains attractive, according to a report released by the U.S. Department of Energy and prepared by Lawrence Berkeley National Laboratory (Berkeley Lab). With prices averaging below 2 cents per kilowatt-hour (kWh) for newly built projects, wind is competitive with other generation sources.Read more
