World energy consumption is the total energy produced and used by humans.

The World Bioenergy Association (WBA) is an international NGO and non-profit association that represents the bioenergy sector globally.

A place where work is conducted, workers interface with machines or systems monitoring system status, entering commands and recording data.

The working fluid of a heat engine or heat pump is a gas or liquid, usually called a refrigerant, coolant, or working gas, that primarily converts thermal energy (temperature change) into mechanical energy (or vice versa) by phase change and/or heat of compression and expansion.

Work hardening, also known as strain hardening, is the strengthening of a metal or polymer by plastic deformation.

In physics, work is the energy transferred to or from an object via the application of force along a displacement.

A gasification unit which converts timber or charcoal into wood gas, a syngas consisting of atmospheric nitrogen, carbon monoxide, hydrogen, traces of methane, and other gases, which – after cooling and filtering – can then be used to power an internal combustion engine or for other purposes.

Wood gas is a syngas fuel which can be used as a fuel for furnaces, stoves and vehicles in place of gasoline, diesel or other fuels.

Wireless slip rings do not rely on the typical friction-based metal and carbon brush contact methods that have been employed by slip rings since their invention, such as those explored above.

Wireless power transfer or electromagnetic power transfer is the transmission of electrical energy without wires as a physical link.

Wire gauge is a measurement of wire diameter.

Wire drawing is a metalworking process used to reduce the cross-section of a wire by pulling the wire through a single, or series of, drawing die(s).

A wire is a single usually cylindrical, flexible strand or rod of metal.

Winter diesel fuel refers to diesel fuel enhanced to prevent it from gelling in cold weather conditions.

Windward is the direction upwind from the point of reference

WindMade is a global (Brussel's based) consumer label for companies, events and products using wind power in their operations or production.

A windcatcher (wind tower, wind scoop) is a traditional architectural element used to create natural ventilation and passive cooling in buildings.

In fluid dynamics, wind waves, or wind-generated waves, are water surface waves that occur on the free surface of bodies of water.

Measures wind direction and communicates with the yaw drive to orient the turbine properly with respect to the wind.

The disturbance of wind speed and direction due to obstacles.
