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.  

First public lighting system that runs on solar and wind energy

Tue, 01/20/2015 - 8:58am
Scientists have developed the first autonomous industrialized public lighting system that works with solar and wind energy.

Wave energy integration costs should compare favorably to other energy sources

Wed, 01/07/2015 - 2:08pm
A new analysis suggests that large-scale wave energy systems developed in the Pacific Northwest should be comparatively steady, dependable and able to be integrated into the overall energy grid at lower costs than some other forms of alternative energy, including wind power.
