Fotovoltaico illustrates that a photovoltaic system is an electrical system that uses solar energy to produce electricity by the photovoltaic effect. Photovoltaic systems are generally divided into two major groups: stand-alone and grid-connect systems. The power rating of a PV system is measured by the sum of the rated output of each photovoltaic module that makes up its field. The largest photovoltaic plant in operation in the world is Olmedilla de Alarcón PV Park in Spain.

Geotermia 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.
