outline is provided as an overview of and topical guide to wind energy:
Wind energy – the kinetic energy of air in motion, also called wind.
Wind energy can be described as all of the following:
Wind Energy – Sun heats up uneven surface of earth, which causes motion of air. Hot air and cold air interchanges their places lead to flow of air. As it has force with motion, It carries kinetic energy. This is called wind energy
Energy – an indirectly observed quantity, often understood as the ability a physical system has to do work on other physical systems.
Renewable energy – energy which comes from natural resources which are naturally replenished.
Natural resource – materials and components (something that can be used) that can be found within the environment. Every man-made product is composed of natural resources (at its fundamental level). A natural resource may exist as a separate entity such as fresh water, and air, as well as a living organism such as a fish, or it may exist in an alternate form which must be processed to obtain the resource such as metal ores, oil, and most forms of energy.
Renewable resource – natural resource with the ability to reproduce through biological or natural processes and are replenished with the passage of time.
Atmosphere – a layer of gases that may surround a material body of sufficient mass, and that is held in place by the gravity of the body.
Wind – the flow of gases on a large scale. Wind is composed of:
Air – the gas found in the Earth's atmosphere. Air is mainly composed of nitrogen, oxygen, and argon, which together constitute the major gases of the atmosphere.
Gas – one of the three classical states of matter (the others being liquid and solid).
Motion – change in position of an object (including particles) with respect to time. Motion is typically described in terms of velocity, acceleration, displacement and time. Flow is a type of motion.
History of sails – The earliest known depictions of sails are from ancient Egypt around 3200 BCE, where reed boats sailed upstream against the River Nile's current.
Age of Sail – the period in which international trade and naval warfare were dominated by sailing ships, lasting from the 16th to the mid 19th
Wind power – conversion of wind energy into a useful form of energy.
Variable renewable energy – any source of renewable energy that is not continuously available due to some factor outside direct control. The variable source may be quite predictable, for example, tidal power, but cannot be dispatched to meet the demand of a power system.
Environmental impact of wind power – relatively minor compared to the environmental impact of traditional energy sources. Wind power consumes no fuel, and emits no air pollution, unlike fossil fuel power sources.
Windmill – a machine which converts the energy of wind into rotational energy by means of vanes called sails or blades.
Windpump – a windmill used for pumping water, either as a source of fresh water from wells, or for draining low-lying areas of land.
Sail – any type of surface intended to move a vessel, vehicle or rotor by being placed in a wind – in essence a propulsion wing
Wind power industry
Wind power industry –
industry involved with the design, manufacture, construction, and maintenance of wind turbines. The modern wind power industry began in 1979 with the serial production of wind turbines by Danish manufacturers. The industry is currently undergoing a period of rapid globalization and consolidation.
Wind farm – group of wind turbines in the same location used to produce electric power. A large wind farm may consist of several hundred individual wind turbines, and cover an extended area of hundreds of square miles, but the land between the turbines may be used for agricultural or other purposes. A wind farm may also be located offshore.
Community wind energy – projects are locally owned by farmers, investors, businesses, schools, utilities, or other public or private entities who utilize wind energy to support and reduce energy costs to the local community.
Wind power in Colorado – has been growing significantly in recent years due to international mass adoption of wind power and the state's aggressive renewable portfolio standard that requires 30% of the state's electricity to come from renewable sources by 2020.
Wind power in Illinois – has been supported by a renewable portfolio standard, passed in 2007, and strengthened in 2009, which requires 10% renewable energy from electric companies by 2010 and 25% by 2025.
Wind power in Indiana – was limited to a few small water-pumping windmills on farms until 2008 with construction of Indiana's first utility-scale wind power facility, Goodland (phase I) with a nameplate capacity of 130 MW.
Wind power in Massachusetts – has vast wind energy resources onshore as well as offshore and the installed capacity has been growing in recent years due to a variety of regulatory actions and financial incentives enacted by the state government.
Wind power in Ohio – has a long history, and as of 2011, Ohio has eleven utility-scale wind power installations installed or under construction, with a combined nameplate capacity of just over 1051 MW.
Wind power in New Zealand – generates a small but rapidly growing proportion of the country's electricity, as the country makes increasing use of its outstanding wind resources.
Wind-powered vehicle – typically uses a sail to harness the wind to propel it. Also includes kite-driven vehicles. The predominant type of wind-powered vehicles are seafaring vessels (sailboats and yachts).
Wind-powered vehicles by type
Sailing ship – a ship with a hull, rigging, and at least one mast to hold up the sails that use the wind to power the ship. The crew who sail a ship are called sailors or hands.
Rotor ship – ship designed to use the Magnus effect for propulsion. To take advantage of this effect, it uses turbosails which are powered by an engine.
Alcyone – ship operated by the Cousteau Society. It was created as an expedition ship and to test the operation of a new kind of marine propulsion system, the turbosail.
E-Ship 1 – a RoLo cargo ship that made its first voyage with cargo in August 2010. The ship is owned by the third-largest wind turbine manufacturer, Germany's Enercon GmbH.
Windmill ship – wind energy conversion system ship or wind energy harvester ship propels itself by use of a windmill to drive a propeller.
Formula AE – a solar and wind powered car. Initial startup is by solar power; as the car travels at faster speeds, strategically placed air intakes are designed to direct air flow to power the wind turbines.
Greenbird – a wind-powered vehicle that broke the land speed record for the fastest wind-powered vehicle at the dry Ivanpah Lake on March 26, 2009.
Racing Aeolus – racing event, for which the student participants were required to design and build a wind-powered vehicle that could drive against the wind, powered by a wind turbine.
Wind-powered vehicle propulsion systems
Sail – any type of surface intended to move a vessel, vehicle or rotor by being placed in a wind—in essence a propulsion wing. Sails are used in sailing.
Turbosail – naval propulsion system based on an application of the Magnus effect. First attempted by Anton Flettner on the Buckau, it was later developed by Jacques-Yves Cousteau who commissioned the Alcyone.
Wingsail – a form of marine propulsion similar to conventional sails.
Wind energy organizations
Airborne Wind Energy Industry Association (AWEIA) – founded in 2009 to serve globally companies and institutions dedicated to converting wind energy for useful loads (airborne wind energy technology) by use of tethered and free-flight aircraft (airborne wind energy AWE); the tethered and free-flight mode is in contrast to using non-tethered ground-connected wind turbines.
BlueEnergy – a non-profit organization building sustainable energy and water systems on the Caribbean coast of Nicaragua.
Citizen Partnerships for Offshore Wind – a collaboration of communities and organizations that believe the United States must move towards indigenous clean energy sources like offshore wind and that public education and citizen engagement are essential to making that transition.
WindEurope, formerly the European Wind Energy Association (EWEA) – an association based in Brussels, promoting the use of wind power in Europe.
Makani Power – an Alameda, California-based company that develops airborne wind turbines.
World Wind Energy Association (WWEA) – an international non-profit association representing the wind power sector worldwide, with members in 100 countries, amongst them the leading national and regional wind energy associations.

Poul la Cour (1846–1908) – Danish scientist, inventor and educationalist. Today, la Cour is especially recognized for his early work on wind power, both experimental work on aerodynamics and practical implementation of wind power plants.
Outline of energy development – Energy development is the effort to provide sufficient primary energy sources and secondary energy forms for supply, cost, impact on air pollution and water pollution, mitigation of climate change with renewable energy.
Betz's law – that may be derived by means of an infinitely thin rotor from a fluid flowing at a certain speed.
Capacity factor – of a power plant is the ratio of the actual output of a power plant over a period of time and its potential output if it had operated at full nameplate capacity the entire time.
