Windsave Turbines are Small, and Can Help Customers Save up to 30 percent on Electricity Costs

Wind turbine noise can be detected at low levels, even when it is heard alongside motorway traffic noise, a study finds. It is possible for louder motorways to drown out turbine noise, however. The participants in this listening experiment could easily detect wind turbine noise, but only once they knew it was present in recordings of environmental noise.

The ecological impacts of micro wind turbines (up to 50 kW) are treated in a diverse way by different local authorities in the UK during the planning approval process, research suggests. The study calls for ecologists, policymakers, planners and industry representatives to improve the integration of ecological information within planning, and for greater guidance for local authorities on the ecological considerations of micro-turbines.

Wind is an important renewable energy source for Europe. The wind power capacity installed in 2014 could produce enough electricity to meet over 10% of the EU’s electricity consumption. However, wind power structures can also be harmful to birds, which can collide with turbines. This study assessed methods of reducing avian collisions with wind turbines and makes several practical recommendations.

Wind energy will likely continue to play a leading role in reaching the EU’s renewable energy targets. However, in some areas wind turbines face social opposition based in large part on the visual impact of wind turbines in the landscape. A new study outlines a novel methodology to measure emotional response to wind turbine visuals, which may assist wind farm planners in gauging public acceptance.

How do offshore wind farms affect marine wildlife? A new study outlines a systematic approach developed for Swedish waters that could also be useful for assessing wind energy impacts on the marine environment more widely.

Only about two or three small birds are killed by wind turbines each year for every 225-300 houses supplied with renewable energy, new research suggests. The study collated data from 116 US and Canadian studies on 156 species of passerines (small birds). The study suggests some species are affected more than others, but that wind turbines generally have only a minor impact on these small-bird populations.

Wind energy is often viewed as environmentally friendly. Still, even if wind turbines are situated so as to not inadvertently kill birds and bats, they may carr

Tyer Wind has based its proposed wind turbines on a hummingbird flapping its wings.

From taller towers to turbines that operate at lower wind speeds, wind energy just keeps on getting better.

Wind turbines can kill birds and bats, but they don't have to. Here are a few ways to help them coexist.

Wind turbine rotor blades include a shell having a leading edge opposite a trailing edge, a structural support member that supports the shell and is disposed internal the wind turbine rotor blade between the leading edge and the trailing edge and extends for at least a portion of a rotor blade span length, and a resistive cellular support structure disposed at least partially about the wind turbine rotor blade that physically supports at least a portion of the wind turbine rotor blade and at least partially absorbs radar energy.

Wind turbine rotor blades with a reduced radar cross sections include a shell having a leading edge opposite a trailing edge, a structural support member that supports the shell and is disposed internal the wind turbine rotor blade between the leading edge and the trailing edge and extends for at least a portion of a rotor blade span length, wherein the structural support member comprises fiberglass, one or more cavities internal the wind turbine rotor blade, and a lightweight broadband radar absorbing filler material disposed in at least one of the one or more cavities to provide the reduced radar cross section.
