Will the Tour de France prologue in Utrecht get the winner it deserves? New aerodynamic research shows that riders in a time trial can save vital seconds by riding closer to the following team car. Over a short distance like the prologue of the Tour de France, that can save as much as 6 seconds: enough to make the difference between winning and losing.
In 2013, Russia implemented an incentive system for renewable energy sources that is based on the wholesale electricity capacity mechanism. It is intended to increase the share of renewable energy in the country's energy production. New researchers demonstrates that the incentive system can make renewable energy investments in wind, solar and small-scale hydro power profitable for investors. However, in order to be profitable the investments must be within the scope of the full Russian support scheme.
A newly designed material, which mimics the wing structure of owls, could help make wind turbines, computer fans and even planes much quieter. Early wind tunnel tests of the coating have shown a substantial reduction in noise without any noticeable effect on aerodynamics.
Scientists report the development of two novel devices that derive power directly from evaporation -- a floating, piston-driven engine that generates electricity causing a light to flash, and a rotary engine that drives a miniature car.
A new methane bioreactor boosts environmentally friendly energy to the markets. The reactor stores renewable energy and produces synthetic biomethane with good efficiency. The new technology can help in achieving a carbon-neutral society, developers report.
It's technically possible for each state to replace fossil fuel energy with entirely clean, renewable energy, experts say. A new report is the first to outline how each of the 50 states can achieve such a transition by 2050. The 50 individual state plans call for aggressive changes to both infrastructure and the ways we currently consume energy, but indicate that the conversion is technically and economically possible through the wide-scale implementation of existing technologies.
Researchers are using state-of-the-art modelling techniques to study the effects of wind on cities, paving the way for design innovations in building, energy harvesting and drone technology.
Male moths locate females by navigating along the latter's pheromone (odor) plume. Two strategies are involved: males must find the outer envelope of the pheromone plume, and then head upwind. Can understanding such insect behavior be useful for robotics research? Yes, according to an entomologist, whose research using computer simulations shows that such insect behavior has implications for airborne robots (drones) that ply the sky searching for signature odors.
Wind turbines began cropping up across the landscapes of Spain and Germany in the 1990s'. These two countries have the highest wind energy production in the EU. But according to the Global Wind Energy Council, the global installed power capacity in Europe -- which is 134,007 MW -- has been surpassed by Asia with 141,964 MW, at the end of 2014. The wind power industry is arguably the most mature -- and fastest developing -- among renewable energies. But, there is still considerable room for improvement to compete with other sources of electricity.
The Francis turbine is the most common type of water turbine used in Norwegian hydropower plants, and has been for many years. About half of the world’s Francis turbines are found in Norwegian plants.
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.
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.
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.
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 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.
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.
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.
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.
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.
