Challenge Climate Change

The challenge of climate change confronts us with the question, under which conditions we want to live on our home planet mother earth. A sustainable development so that also future generations can satisfy their needs seems necessary. We must sustain our living basis, because there is no second earth where we could fly to.

The power of the wind.

Stefan Jung • 24. Juni 2024

The power of the wind is used since a very long time, like sail-ships and windmills.

The origin of the winds has a simple explanation. The rays from the sun are shining on the different surface structures of mother earth, like deserts, seas, forests, land and mountains. The respective air masses are heated - more or less. Different temperatures and pressures lead to different air densities and air movements, while the earth is rotating.

One vital formula to describe a given wind power is:  P = A * v³ * 0,5 * ϱ

P stands for power, A for a certain area (the blade wide of a wind turbine), v is the wind velocity, 0,5 is a physics factor, and ϱ stands for the air-density. The higher the variables are, the higher the harvested wind power could be. It depends on the local conditions and the efficiency of the used technologies. Usually, the wind speeds are higher more above the earth surface, because the surface acts like a brake. Most types of wind turbines work against the wind.
