The sources of renewable energy
As everyone surely knows, not all energy sources are available to us indefinitely. In fact, there are energy sources that are not renewable and their fate to run out over time; they are needed to regenerate them millions of years, which is why you cannot define ” renewable ”.
Among them is the type of fossil fuel, ie oil, coal, and natural-gas type, also there is the fuel that generates nuclear energy. But when it comes to renewable energy sources, we refer to all non-fossil sources of energy, such as solar, wind, hydro, wave, geothermal and biomass, which are always played in a short time.
This guide will talk about three very important sources of renewable energy: wind, solar and photovoltaic energy.
Wind energy has been used since ancient times; with it is possible to make use of simple installations and with excellent reliability. The wind is an inexhaustible source of energy, clean and free of charge. It has an irregular and its intensity can vary. Therefore, to be able to get ” good ” electricity. We need very high speed of the rotation of the blades.
Systems with thermal panels capture and take advantage of solar energy can heat the water carrying it and distributing it in the normal network. Are placed on the side exposed to the sun of a building (roof, terrace, garden) placing them at an incline (from 30 ° to 60 °), to catch the best-rays.
In homes, the system with solar panels involves heating to heat the water of the various rooms and any pool. Sometimes you can even get 80% of the entire heating requirements of the house but since everything depends on the Sun, in this case, it is necessary to integrate this thermal system clean with a traditional system.
The solar thermal energy is a type of energy that comes from the heat then obtained thanks to the sun. It can be captured in different ways, and it is not any use for different energy needs. A photovoltaic system consists of an electrical system that uses the energy of the sun.
An attacker could then transform solar energy into electricity. The latter may accumulate in batteries to be able to always have been available (giving origin to autonomous solar installations), or it can be immediately distributed to the user without the need for batteries.
