The growth of renewable energies is conditioned by the energy policies of governments, by investment in research and by the change of attitude of citizens towards responsible consumption.
However, more and more people are concerned about reducing CO2 emissions to the atmosphere and maximizing the resources of the environment in their day to day lives in order to achieve a much cleaner world.
There are some types of little-known renewable energies that individually can supply, if not completely, most of the energy needs of a home, and it is the duty of each person to inform themselves of what they are since they can later be most commonly used all over the world.
In this article, we will take a look at those renewable energies that are practically unknown and how they would help the world.
It is a type of energy that takes advantage of the heat energy that contains the air of the environment and is in constant renovation through the solar energy that receives the terrestrial crust.
The thermal heat pumps transform the heat into energy, regardless of the temperature of the outside and both in winter and summer.
It allows reaching temperatures above 60 °c, which makes this renewable can replace conventional heating systems, and also, with the same system, refrigerate a house in the summer months.
Geothermics uses the energy stored in the form of heat that is below the surface of the Earth. The weather conditions do not influence its use, it is available the 365 days of the year 24 hours a day.
It can supply 100% of the heating needs and the consumption of hot water of a house or building, with the possibility of being used as refrigeration in summer.
This renewable energy completely eliminates the dependence of other fossil fuels, however, it requires an external installation (ground drilling) and interior (installation of thermal floors).
Biomass is another type of energy obtained from organic compounds transformed by natural processes. It is the organic matter originated through a biological process, spontaneous or provoked, usable as a source of energy. It is clean and its residues are biodegradable.
In addition, due to human activity CO2 is produced continuously with maximum utilization of the matter. That’s why renewable energy is being installed in many places in the world, through the construction of large biomass plants.
All three are energies that reduce CO2 emissions and are alternatives to traditional electricity consumption. Only through research new methods are improved to take advantage of the resources that nature gives us.
