How Is Wind Energy Produced? Sciencing

The Wind Energy Foundation explains how the generating capacity varies with the square footage of area swept by the rotors, by wind speeds and even by the density of the air due to variations in temperature and altitude. The energy available in wind increases by the cube of the speed -- that is, a twofold increase in wind speed yields eight times the power. The most precise measure of a

How Much Power Does a Wind Turbine Generate? Sciencing

For example, a 1.5-megawatt wind turbine with an efficiency factor of 33 percent may produce only half a megawatt in a year -- less if the wind isn't blowing reliably. Industrial scale turbines usually have capacity ratings of 2 to 3 megawatts. However, the amount of energy actually produced is reduced by efficiency and wind availability -- the percentage of time a unit has enough wind to move.

Overblown: Wind turbines don’t take more energy to build

A viral post on Facebook claims that wind turbines cost more energy to produce than could ever be gained back from them. This is incorrect. This text is selectively quoted from an essay written by scientist David Hughes, and published in 2009 in an anthology edited by Thomas Homer-Dixon.

How To Calculate Power Output Of Wind Windpower

26/01/2010Although the calculation of wind power illustrates important features about wind turbines, the best measure of wind turbine performance is annual energy output. The difference between power and energy is that power (kilowatts [kW]) is the rate at which electricity is consumed, while energy (kilowatt-hours [kWh]) is the quantity consumed.

The cost of energy generated by wind power

The Cost of Energy Generated by Wind Power. The total cost per kWh produced (unit cost) is calculated by discounting and levelising investment and O&M costs over the lifetime of the turbine, and then dividing them by the annual electricity production. The unit cost of generation is thus calculated as an average cost over the turbine’s lifetime. In reality, actual costs will be lower than the

Calculating the energy production of a wind turbine

The bottom line with a wind turbine is how much energy it produces. Do not confuse this with the maximum power output! Rated power output is only achieved at rated windspeed, which will only occur from time to time. The energy produced depends on the average power and not the peak power. This in turn depends mostly on the turbine’s physical size (diameter) and the site average windspeed
