Wind Energy Basics - Department of Energy
Wind energy is actually a byproduct of the sun. The sun’s uneven heating of the atmosphere, the earth’s irregular surfaces (mountains and valleys), and the planet's revolution around the sun all combine to create wind. Since wind is in plentiful supply, it’s a sustainable resource for as long as the sun’s rays heat the planet.

Wind energy is one of the largest sources of clean, renewable energy in the United States, making it essential to a future carbon-free energy sector. Wind turbines do not release emissions that pollute our air or water, and they can be built with minimal impact to the environment or livelihoods of nearby residents.
This chapter quantifies these fundamental concepts and discusses the nature of wind. Key words: Wind energy flow rate, kinetic energy flux, wind power density, power coefficient, Betz Limit, capacity factor, source of wind energy. 1 Wind physics basics: what is wind and how wind is generated . Wind is atmospheric air in motion. 1

Wind is a renewable energy source. Overall, using wind to produce energy has fewer effects on the environment than many other energy sources. Wind turbines do not release emissions that can pollute the air or water (with rare exceptions), and they do not require water for cooling.
How Do Wind Turbines Work? | Department of Energy
This video highlights the basic principles at work in wind turbines and illustrates how the various components work to capture and convert wind energy to electricity. See the text version.
Wind explained - U.S. Energy Information Administration (EIA)
Dec 27, 2023 · An introduction to wind energy and how it forms, and to of the daily wind cycle.
Current and projected characteristics for onshore and offshore wind turbines. Offshore wind turbines have higher hub heights and larger rotor diameters. Wind speeds are typically higher, more consistent, and less turbulent offshore. Offshore wind farms are not constrained by land availability but have separate permitting considerations.
