# Wind Turbines Yield Calculator

Calculates the production of electricity and revenue of wind turbines of a given size at different wind speeds. n is the number of wind turbines of the same model at the same place. Radius means the length of a rotor blade from the hub to the tip. Average values ​​are preset for air density and efficiency; for an explanation of these values, see Wind Turbine Power Calculator. The electricity tariff is how much is paid for one kilowatt-hour.
In the second table, up to ten wind speeds and their duration in days, hours, minutes and seconds can be entered. For every value, the amount of produced energy is calculated. If the electricity tariff is given, the income is calculated.
The designation of an average wind speed is not useful, because the wind speed is calculated to the power of three. Strong winds more than compensate for a lull. The shutdown speed of the wind turbines is not taken into account; wind with a speed above the shutdown speed should not be entered at all.

Example: two wind turbines with a rotor blade length (radius) of 100 meters produce electricity which can be fed into the grid for 5 cents per kilowatt-hour (0.05 €/kWh). The wind blows for one hour with 12 meters per second and for half an hour with 15 meters per second. I this time, 51.5 megawatt-hours of electric energy is produced, which can be sold for 2575.23 €.

Of course, such a calculator cannot fully reflect reality, as wind speed changes constantly in practice. It can be used to get an overview of the electricity generated and the expected income. The shorter the time periods you specify, the more precise the calculator becomes, but the more complex the entry is.
