Water is used around the world for the production of electricity, but new research results show that there will not be enough water in the world to meet demand by 2040 if the energy and power situation does not improve before then.
New research outlines the path to a possible future for California in which renewable energy creates a healthier environment, generates jobs and stabilizes energy prices.
By using sophisticated GPS tracking to monitor seals' every movement, researchers have shown for the first time that some individual seals are repeatedly drawn to offshore wind farms and pipelines. Those human-made structures probably serve as artificial reefs and attractive hunting grounds, according to a study.
Fire is the second leading cause of accidents in wind turbines, after blade failure, according to research. Wind farming is one of the leading industries in the renewable energy sector. However, the industry faces a number of challenges, such as opposition by wind farm lobbyists. Today's research suggests that incidents of wind turbines catching fire are a big problem that is not currently being fully reported.
Scientists have developed a rechargeable battery that is all organic and could be scaled up easily for use in power plants where it can make the energy grid more resilient and efficient by creating a large-scale means to store energy for use as needed. The batteries could pave the way for renewable energy sources to make up a greater share of the nation's energy generation.
A first-of-its-kind study using snow during a Minnesota blizzard is giving researchers new insight into the airflow around large wind turbines. This research is essential to improving wind energy efficiency, especially in wind farms where airflows from many large wind turbines interact with each other.
Researchers have carried out an environmental lifecycle assessment of 2-megawatt wind turbines mooted for a large wind farm in the U.S. Pacific Northwest. They conclude that in terms of cumulative energy payback, or the time to produce the amount of energy required of production and installation, a wind turbine with a working life of 20 years will offer a net benefit within five to eight months of being brought online.
The SOPCAWIND tool is a piece of software that facilitates the design of wind farms, bearing in mind not only the aspects of energy productivity but also the possible impact the wind farm may have on the environment, radars or other telecommunications systems in the vicinity. It also assesses acoustic noise, the effect of shadow on nearby housing, and applies criteria for heritage protection or clearance from transport networks and certain facilities.
As an outcome from the continuous hybrid renewable energy research, an innovative outdoor lighting system powered by a shroud-augmented wind turbine and a solar panel was installed in the Kuala Lumpur campus of University of Malaya (UM).
Under favorable atmospheric conditions any elevated structure can generate upward lightning flashes. Even aircraft can do so —- in fact, height and movement are two of the factors that contribute to this phenomenon. The tips of wind turbine blades move at speeds of several tens of meters per second. However, no one had previously demonstrated the relationship between this movement and the triggering of electrical discharges.
Sandia National Laboratories has finished eight days of testing a full-scale mock unit representing the aerodynamic characteristics of the B61-12 gravity bomb in a wind tunnel. The tests on the mock-up were done to establish the configuration that will deliver the necessary spin motion of the bomb during freefall and are an important milestone in the Life Extension Program to deliver a new version of the aging system, the B61-12.
