As climate change causes severe effects like global warming, the rise of the sea level, extreme atmospheric phenomena, desertification, and the extinction of many species, a series of agreements and initiatives have emerged to try to mitigate it. Solar and aerothermal power are two allies that have been gathering momentum in this fight.
Both were created with the purpose of having a renewable and non-polluting energy source for domestic use. Many homes are already using them in Spain, but its use and advantages continue to be unknown for many. Experts estimate that this could become the cheapest energy generation method by 2040. However, due to its current high installation costs, the Spanish government has created subsidies to promote its use.
El Plan de Energía y Clima no evita que la dependencia energética de España siga estando muy por encima de la media europea en 2030 @greenpeace_esp @AmigosTierraEsp @ecologistas @WWFespana @NuModEnergetico @twitt_odg @ocenergia https://t.co/EJObGlUZ9v vía @ERenovables

Clean solar and aerothermal power
Solar energy is generated through electromagnetic radiation from the sun, which enables to obtain both electric and thermal energy. The technology used to harness solar power in homes is photovoltaic, produced with solar panels and solar counters.
For its part, aerothermal power is a technology that facilitates extracting energy contained in the air. Windmills (still not developed) and aerothermal systems (currently utilized) are used to harness this energy. These systems consist of heat pumps designed to achieve an adequate temperature, be it for refrigeration during the summer or heating water throughout the year. These pumps extract heat from the air and transport it to the room or the water.
While the elements to obtain most of this energy come from nature and are free, it requires a small amount of electricity to reach the desired temperature. In order to eliminate this cost, companies in this sector have integrated small PV panel installations that supply the energy needed to power this heat pump. The combination of solar and aerothermal power achieves energy efficiency and cover the household’s thermal requirements completely free of charge.
