| solar |
| Heat generation through solar collectors, which fulfil needs such as domestic hot water (DHW), heating or radiant floor heating for different spaces such as homes, hotels, schools, factories, sport centres, etc.; and even climate controlled of heated swimming pools or spas. |
| geothermal power |
| Geothermal energy is the earth’s inner energy which is accumulated in its layers with a constant temperature during the whole year. Thus these inner layers are used as temperature regulators. This is a very efficient source of energy for air-conditioning systems and can also be used as a balancing element for other systems based on renewable energies, such as solar air-conditioning |
| bio-mass power |
| A system based on the combustion of biological resources for energy generation, ranging from the exploitation of forest residues or agricultural residues, to the farming products exclusively aimed at the generation of fuel or gas from the decomposition of organic material |

consultation| wind power |
| This power is obtained from wind currents, and does not require any combustion yielding CO2 emissions, thus not contributing to the green effect nor climate change |
