Wind gradient

energy

The rate of increase of wind strength with unit increase in height above ground level.

Wind hybrid power systems

energy

Wind hybrid power systems combines wind turbines with other storage and/or generation sources.

Wind lens

energy

The wind lens is a modification on the wind turbine created by Professor Ohya from the Kyushu University as an attempt to be more efficient in production of electricity and less invasive to both humans and nature.

Wind power

energy

Wind power or wind energy is the use of wind to provide mechanical power through wind turbines to turn electric generators for electrical power.

Wind power density (WPD)

energy

A quantitative measure of wind energy available at any location.

Wind power forecasting

energy

A wind power forecast corresponds to an estimate of the expected production of one or more wind turbines (referred to as a wind farm) in the near future.

Wind power industry

energy

The wind power industry is involved with the design, manufacture, construction, and maintenance of wind turbines.

Wind profile power law

energy

The wind profile power law is a relationship between the wind speeds at one height, and those at another.

Wind profiler

energy

A wind profiler is a type of weather observing equipment that uses radar or sound waves (SODAR) to detect the wind speed and direction at various elevations above the ground.

Wind resource assessment

energy

A process to estimate the future energy production of a wind farm.

Wind rose

energy

A wind rose is a graphic tool used by meteorologists to give a succinct view of how wind speed and direction are typically distributed at a particular location.

Wind shadow

energy

A turbulent and/or low-wind-speed region downwind of an object such as a buildings or trees.

Wind shear

energy

Wind shear (or windshear), sometimes referred to as wind gradient, is a difference in wind speed or direction over a relatively short distance in the atmosphere.

Wind speed

energy

In meteorology, wind speed, or wind flow speed, is a fundamental atmospheric quantity caused by air moving from high to low pressure, usually due to changes in temperature.

Wind tree

energy

A wind tree contains "leaves" that act as mini wind-turbines to generate electricity.

Wind turbine aerodynamics

energy

The shape and dimensions of the blades of the wind turbine are determined by the aerodynamic performance required to efficiently extract energy from the wind, and by the strength required to resist the forces on the blade.

Wind turbine blades

energy

The aerodynamic surface that catches the wind.

Wind turbine blades balancing

energy

Adjusting the weight and weight distribution through 2 axes so that all blades are the same.

Wind turbine design

energy

Wind turbine design is the process of defining the form and specifications of a wind turbine to extract energy from the wind.

Wind Turbine Installation Vessel INNOVATION

marine

Delivered in August 2012, the INNOVATION is a self-propelled powerful jack-up built by CRIST S.A. shipyard in Gdynia (Poland).
