Chapter 1 - basic energy concepts solar, water and wind energy, as well as geothermal energy fossil energy is contained in coal, oil and natural gas. The peak wind energy occurs at wind speeds considerably above both the modal and average wind speeds since the wind energy content is proportional to the cube of its speed very little energy is available at low speeds and most of this will be needed to overcome frictional losses in the wind turbine. What is wind energy wind energy is energy from moving air, caused by temperature (and therefore pressure) differences in the atmosphere irradiance from the sun heats up the air, forcing the air to rise.
To understand wind energy, we subscribe to the theory of conservation of mass and conservation of energy a duct shown below is assumed to represent wind flowing in and out of the blades of the turbine the blade element theory assumes that the flow at a given part of a wind turbine blade does not .
