Huge energy potential in open ocean wind farms in the North Atlantic
9 Oct 2017 at 12:49pm
Because wind speeds are higher on average over ocean than over land, wind turbines in the open ocean could in theory intercept more than five times as much energy as wind turbines over land. This presents an enticing opportunity for generating renewable energy through wind turbines. But it was unknown whether the faster ocean winds could actually be converted to increased amounts of electricity.
A beautiful wing design solution inspired by owl feathers

Researchers have formulated a mathematical solution that could help minimize noise, maximize aerodynamics in design of porous airfoils (2-D wings) to improve wind turbines and air vehicles.
Energy harvested from evaporation could power much of US
26 Sep 2017 at 9:51am
In the first evaluation of evaporation as a renewable energy source, researchers find that US lakes and reservoirs could generate 325 gigawatts of power, nearly 70 percent of what the United States currently produces.
A sustainable future powered by sea
22 Sep 2017 at 6:40am
Researchers develop turbines to convert the power of ocean waves into clean, renewable energy.
How safe are critical infrastructures from hacker attacks?
9 Sep 2017 at 3:37pm
Critical infrastructures such as wind power stations are partially controlled via mobile phone networks. Using state-of-the-art tests, researchers are investigating how well protected that form of communication is from external attacks. The team is aiming to make critical infrastructures in Europe able to withstand hacker attacks.
Finding better wind energy potential with the new European Wind Atlas
6 Sep 2017 at 10:55am
Over the last 25 years, the world has seen an increased dependency on wind energy that promises to continue growing. This has created an ever-evolving process to develop a method that can accurately assess a region's wind energy potential.
Light-based method improves practicality and quality of remote wind measurements
6 Sep 2017 at 8:46am
Researchers have developed a new remote sensing instrument based on light detection and ranging that could offer a simple and robust way to accurately measure wind speed, which could help scientists better understand how hurricanes form and provide information to pinpoint landfall earlier.
Firebricks offer low-cost storage for carbon-free energy
6 Sep 2017 at 8:46am
Researchers draw from an ancient technology in their latest solution to enabling rapid expansion of wind, solar and nuclear power. Heat-storing firebricks could be used to level electricity prices for renewables, they propose.
How 139 countries could be powered by 100 percent wind, water, and solar ener...
23 Aug 2017 at 9:13am
The latest roadmap to a 100 percent renewable energy future outlines infrastructure changes that 139 countries can make to be entirely powered by wind, water, and sunlight by 2050 after electrification of all energy sectors. Such a transition could mean less worldwide energy consumption due to the efficiency of clean, renewable electricity; and a net increase of over 24 million long-term jobs.
Fundamentals of water repellency revealed
14 Aug 2017 at 6:27am
The frictional mechanism that resists the motion of drops on inclined surfaces and when affected by wind drag has now been revealed by a team of researchers. They have also developed a theory by which sliding of drops off surfaces of different materials can be predicted. This makes it possible to systematically develop hydrophobic surfaces by modifying their base material and roughness.
Night vision for bird- and bat-friendly offshore wind power
11 Aug 2017 at 7:20am
ThermalTracker software analyzes video with night vision, the same technology that helps soldiers see in the dark, to help birds and bats near offshore wind turbines.
Jackdaws flap their wings to save energy
11 Aug 2017 at 6:36am
For the first time, researchers have observed that birds that fly actively and flap their wings save energy. Biologists have now shown that jackdaws minimize their energy consumption when they lift off and fly, because the feathers on their wing tips create several small vortices instead of a single large one. The discovery could potentially be applied within the aeronautical industry.
Prairie-chicken nests appear unaffected by wind energy facility
9 Aug 2017 at 4:33am
Wind energy development in the Great Plains is increasing, spurring concern about its potential effects on grassland birds, the most rapidly declining avian group in North America. However, a new study suggests that for one grassland bird species of concern -- the greater prairie-chicken -- wind energy infrastructure has little to no effect on nesting. Instead, roads and livestock grazing remain the most significant threats to its successful reproduction.
Annual wind report confirms tech advancements, improved performance, low wind...
8 Aug 2017 at 11:55am
Wind energy pricing for land-based, utility-scale projects remains attractive to utility and commercial purchasers, according to an annual report released by the US Department of Energy. Prices offered by newly built wind projects in the United States are averaging around 2¢/kWh, driven lower by technology advancements and cost reductions.
Distributed wind power keeps spinning, growing
8 Aug 2017 at 11:55am
America's use of distributed wind -- which is wind power generated near where it will be used -- continues to grow, according to the 2016 Distributed Wind Market Report.
