Wind Power Is Not the Answer

The debate about renewable energy sources such as wind power is distorted. We can't rely solely on wind turbines, which will not in themselves be able to supply our energy needs, and which have major disadvantages for the environment, animals, and humans.

Although wind power is a renewable source of energy, it has been shown to have major negative effects on the environment. Wind turbines emit a loud noise which disturbs residents living near windfarms and can also disturb and frighten wild and domestic animals – not least birds. In addition, the turbines kill a large number of insects, such as bumblebees and bees, which are fundamental for continued life.

When windfarms are deployed in our oceans and lakes, they also harm marine life.
Just to construct a 10 MW offshore wind turbine, you need either a 5,000-tonne concrete foundation or a 1,000-tonne steel one. The tower requires around 600 tonnes of steel, the hub another 100 tonnes, the generator yet another 450 tonnes and the rotor blades 40 tonnes of composite material. Is this really climate friendly?

Even when windfarms are being deployed places where there is a lot of wind, it is not possible to rely on wind turbines as our only source of energy. There may be long periods without enough wind, and this requires alternative sources for electricity generation.

Also, wind turbines must be replaced after about 15 to 20 years. By comparison, nuclear power plants have a life expectancy of about 80 years and hydropower plants about 100 years. Comparing the material requirements of nuclear and wind power for the same amount of energy produced, wind power requires 70 times more concrete and 20 times more steel than nuclear power.

Many say that wind power is the answer.
But how can it be considered sustainable?
