# Wind Energy and Wind Power Calculator

Calculate the kinetic energy of wind and wind power based on given parameters.

The Wind Energy and Wind Power Calculator allows you to estimate the kinetic energy of wind and the corresponding wind power. By considering the surface area, wind speed, duration, and air density, you can calculate the energy and power associated with the wind. Wind energy represents the kinetic energy of air in motion, considering its density and velocity. To estimate wind energy, the calculator employs the formula:

where:
E is the wind energy,
A is the surface area perpendicular to the wind direction,
t is the duration of the wind,
ρ is the density of air, and
v is the wind speed.

Additionally, wind power is the energy per unit time, so the wind power formula is:

The Wind Energy and Wind Power Calculator utilizes these formulas to provide the estimated wind energy and wind power. #### Wind energy and wind power

Surface perpendicular to the direction of the wind
Default value is density of air at sea level standard pressure and temperature.
Digits after the decimal point: 2
Wind energy, Joules

Wind power, Watts

However, it's important to note that wind energy, as calculated, represents the kinetic energy of the wind and needs to be converted into another form of energy, such as electrical energy. Albert Betz's research showed that the maximum amount of kinetic energy that can be captured from the wind is around 59.3%.

To give you an idea about wind energy and power, below are some fun facts for reference.

Energy:
The heat required to raise the temperature of 1 liter of water from 20°C to 100°C is 335 000 Joules
1 kW·h is 3 600 000 Joules
Energy of explosion of 1 tonn of TNT is 4 184 000 000 Joules

Typical power of electric kettle ranges from 800 to 2500 Watt
Eurostar train has a power of 12 000 000 Watt.
