A global north-to-south shift in wind power by end of century
11 Dec 2017 at 9:04am
Wind resources in the next century may decrease in many regions in the Northern Hemisphere -- and could sharply increase in several hotspot regions down south.
Transformation to wind and solar achievable with low indirect GHG emissions
8 Dec 2017 at 8:35am
Different low carbon technologies from wind or solar energy to fossil carbon capture and sequestration (CCS) differ greatly when it comes to indirect GHG emissions in their life cycle. The new study finds that wind and solar energy belong to the more favorable when it comes to life-cycle emissions and scaling up these technologies would induce only modest indirect GHG emissions -- and hence not impede the transformation towards a climate-friendly power system.
Inspecting rotor blades with thermography and acoustic monitoring
1 Dec 2017 at 7:47am
Wind turbines have a design life of 20 years. The rotor blades must be regularly inspected at least once every four years to verify their structural integrity. This type of work is performed by industrial climbers. But the problem with inspecting offshore installations is that access is only possible when wind and weather conditions permit. This makes it very difficult to plan inspection visits. In the Thermoflight research project, scientists are working together with industrial and research partners to investigate alternative inspection methods. The use of offshore drones equipped with thermal imaging cameras in combination with acoustic monitoring systems could potentially improve maintenance efficiency and help reduce downtime.

17 Nov 2017 at 11:17am
A team of leading computer scientists has developed a novel computational system to aid the design and fabrication of wind-up toys, focusing on automating the intricate interior machinery responsible for the toys' wind-up motion.
Among 'green' energy, hydropower is the most dangerous
25 Oct 2017 at 7:31am
Many governments are promoting a move away from fossil fuels towards renewable energy sources. However, in a new study, scientists highlight some of the ecological dangers this wave of 'green' energy poses.
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.
