It is the kinetic energy in the wind, which is half the mass times the velocity-squared, summed up for every small element of air in the wind.

How much windenergy of the total windenergy directed at a windturbine is converted into heat and electricy and so how much of the total windenergy that was available to the windturbine is left over?
modern wind turbines are only about 30% efficient
What are the 3 basic components of modern windenergy systems?
the three are BATTERIES, INVERTERS, and RECTIFIER (whatever that is.)
What are apparent environmental impacts associated with this?
Wind power is blamed for several impacts on health and the environment:Claim: Wind power kills birds that fly into the blades of the turbines. Discussion: Some birds may die this way but no data is available, However bird deaths associated with windows on tall city buildings, home window collisions, car impacts, and free roaming domestic cats are calculated to be in the 100s of millions up to billions a year. Turbine related deaths are probably minimal compared to theseClaim: Wind power sites create subsonic noise that impacts people's health. Discussion: Not supported by actual scienceClaim: Turbine sites change wind speed and direction altering the climate. Discussion: Wind power sites are small in comparison to the Earth'a surface. Windenergy is shed or modified by trees, landforms, buildings and city heat islands effects and similar effects, The impact of turbines would be insignificantClaim: Wind power sites are ugly Discussion: A matter of taste. Smoke belchinf power plants have always been low on the artistic scale to many
