shaft
Wind blows past the blades
The blades rotate around a hub
The hub is connected to a shaft inside
the head.
The rotanting shaft powers a generator
to convert the energy into elecricity
Electricity is sent via pylons and
cables to homes around the couyntry.
The Gheothermal energy
is a another renewable
Energy.This energy
develops the stream
