Impianto minieolico illustrates wind turbines for domestic use. Such a turbine is primarily made up of a tower with a height of 10 to 30 feet, planted in the ground and fastened by several bolts. On top of the tower is installed a wind generator that consists of a series of blades (usually three) and an alternator. The higher the position of the turbine faster the wind, the greater the power generated.

Impianti geotermici illustrates that the energy stored in the subsoil can be harnessed by humans using different technologies. The most common applications are: geothermal probes, ground coils, heat pump wells, energy rods and thermal spring water.
