Wind power
Wind energy is a form of energy that is discussed intensively and sometimes unobjectively in Germany. At the same time, all scientific studies show that wind energy is elementarily important for Germany among the renewable energies.
But why is this so and how high is the potential of wind power in Germany really?
How does a wind turbine generate electrical energy in the first place?
Wind power expansion - how do we manage it?
Approximately 60,000 new wind turbines are needed to implement the energy turnaround in Germany (40,000 on land and 20,000 offshore.) This is a challenging task. There are often numerous protests against the expansion of wind energy. In the worksheet, the arguments of the opponents of wind power are examined and evaluated.

Potential of Wind Power in Germany or Wind of Change: the Answer Is Blowing In The Wind
Wind power uses the kinetic energy of the wind to convert it into electrical energy. Kinetic energy has always been taught in physics classes. Instead of calculating the kinetic energy of sledding, this topic is a good way to teach the students the meaning of the kinetic energy formula and to practice using formulas.
In order to estimate the potential of wind energy, the kinetic energy of the wind is calculated using the kinetic energy formula and the average wind speed.
Since wind turbines must not be too close to each other, otherwise they will take the wind away from each other, one can calculate the energy yield per square meter and thus obtain the potential of 40kWh per person per day.
