Wind energy
Each area of this earth needs its own energy source.
A renewable form of energy that is also sufficiently available there.

In addition to the infinite solar (sun) energy
is wind energy, the subject of this page. An outstanding source of energy.

But if you are looking for a “right” system, you will face questions about size, yield and cost. The offer for this is huge worldwide. Just search the internet!
In search of a system that corresponds to our idea to enable all functional contents by self-construction of a wind turbine, we came across the DIY Open Source System by Hugh Piggot.
