Storms and microbes are behind the mystery of the wandering stones

Thu, 05/21/2015 - 8:18am
The 'sailing' stones of Death Valley in California are famous for apparently moving by themselves, with the phenomenon not being exclusive to this North American desert but also occurring in Spain, in the Manchego lagoon Altillo Chica. Researchers have observed that wind from winter storms generates currents that can push the stones over a surface colonized by microbes. Then once the water has vanished, the mysterious trail is left on the dry bottom of the lagoon.

American energy use up slightly, carbon emissions almost unchanged

Wed, 05/20/2015 - 11:28am
Americans' energy use continued to grow slowly in 2014, fueled by increases in the use of natural gas, wind and solar, according to the most recent energy flow charts.

Offshore wind turbine construction could be putting seals' hearing at risk

Tue, 05/19/2015 - 8:02pm
Noise from pile driving during offshore wind turbine construction could be damaging the hearing of harbour seals around the UK, researchers have found. They say more research is needed on how noise affects marine mammals' hearing and into engineering solutions to reduce noise levels.

Shifting winds: An early warning for reduced energy

Tue, 05/12/2015 - 11:39am
Chinook winds can precede large shifts in wind power output from wind farms -- a challenge for companies seeking to provide a constant stream of green energy to consumers. By establishing a connection between local meteorological events and power grid output, the researchers hope that they may ultimately help grid operators more accurately predict fluctuations in flow and manage the grid accordingly.

Wind turbines: Generating eco-friendly power with metal rotor blades

Thu, 05/07/2015 - 7:19am
Wind turbines deliver environmentally friendly electricity. Yet the fiber-reinforced plastics often used in very large rotor blades are almost impossible to recycle. Not so with steel blades: since these are composed of steel, their recyclability exceeds 90 percent. Plus they cost significantly less than comparable plastic blades.

Vulnerable grassland birds abandon mating sites near wind turbines

Wed, 05/06/2015 - 3:42pm
Shifting to renewable energy sources has been widely touted as one of the best ways to fight climate change, but even renewable energy can have a downside, as in the case of wind turbines' effects on bird populations. In a new paper, a group of researchers demonstrate the impact that one wind energy development in Kansas has had on Greater Prairie-Chickens (Tympanuchus cupido) breeding in the area.

Industrial virtual factory lowers costs and reduces emissions

Thu, 04/23/2015 - 7:51am
Scientists have developed a cloud-based, easily customized, modular software platform for improving the sustainability performance of industrial products by lowering production costs and reducing emissions. The platform provides a virtual collaborative environment for organizations that are jointly developing the same product and/or service. The system, created during the recently completed EPES (Eco-Process Engineering System for composition of services to optimise product life-cycle) project, effectively combines a context-aware approach, cloud services, industrial internet, collaborative networks, simulation and assessment of environmental impacts.

Shifts in electricity generation spur net job growth, but coal jobs decline

Tue, 04/07/2015 - 11:41am
In four years following the 2008 recession, the US coal industry lost more than 49,000 jobs, while the natural gas, solar, and wind industries together created nearly four times that amount, according to a new. Few of the new jobs were added in states hardest hit by coal's decline, particularly West Virginia and Kentucky.

Stormy weather ahead for wind farms?

Mon, 03/30/2015 - 3:24pm
Researchers will study the vibrations of wind turbines at a large Chilean wind farm along with health impacts on nearby residents. The goal is to make wind turbines more acceptable. Currently, scientists lack sufficient understanding of wind turbines' noise and best ways to mitigate the effects, they say.

Benefits of adding a second, smaller rotor to wind turbines

Mon, 03/09/2015 - 4:45pm
Aerospace engineers are developing dual-rotor technology to improve the energy harvest of wind turbines. The idea to look for better performance by adding a second rotor to wind turbines came from a previous study. The researchers used wind tunnel tests to see how hills, valleys and the placement of turbines affected the productivity of onshore wind farms.

Borrowing from whales to engineer a new fluid sensor

Mon, 03/02/2015 - 7:08am
Researchers have borrowed from biological structures called tubercles that humpback whales use to maneuver in the ocean to make a piezoelectric energy harvester for use as an airflow or fluid speed and direction-sensing device.

Wind-powered freighters

Fri, 02/27/2015 - 8:45am
To make ships more eco-efficient, engineers have been working with alternative fuels. A Norwegian engineer is currently pursuing a new approach: With VindskipTM, he has designed a cargo ship that is powered by wind and gas. Software will ensure an optimum use of the available wind energy at any time.

Numerous bats killed by German wind turbines: Migratory bats at risk

Tue, 02/10/2015 - 9:18pm
Numerous bats are killed by German wind turbines. The number of such turbines, already very high, is planned to be increased further. More than two-thirds of bats being killed by wind turbines on German ground are migrants on their way between summer and winter habitats. Due to its geographical location in Europe, Germany has consequently a central responsibility for the conservation of migratory bats.

Fishing vessel transformed into a wave power plant

Mon, 02/09/2015 - 9:49am
Researchers are demonstrating that it is possible for a redundant fishing vessel to be used as a power plant. The first vessel of its kind is now anchored offshore in the Stadthavet area west in Norway, with the aim of generating electricity from the natural forces of the sea.

Solar and wind power will be the cheapest forms of energy in the future

Thu, 02/05/2015 - 8:30am
A new study demonstrates that an energy system based completely on renewable forms of energy will be economically viable in the future. Within ten years, solar and wind power will be the cheapest forms of energy production for Asia's largest energy markets.

How is noise produced by wind power plants experienced?

Tue, 02/03/2015 - 9:43am
The disruptiveness of the noise generated by wind power plants in Finland is the focus of a new study that combines the measurement of the noise produced by wind power with the noise experienced by humans in relation to sound pressure levels and the time and frequency behavior of sound.
