The power of the main energy source has long been attributed to oil with a consumption of 33.1%. However, in view of the growing problem of climate change and all the measures to be taken to reduce CO2 emissions, the use of energy other than fossil fuels is essential. Renewable, clean and sustainable energy in other words.
 
Renewable energy or “green energy” is the term that designates all the means of producing energy from inexhaustible natural sources.

Unlike fossil fuels, green energy is sustainable, suitable for the current environmental context and the world’s energy needs, whatever they may be, while preserving future generations from possible shortages. It is also said to be clean, because its exploitation does not emit any CO2, thus minimizing the destruction of the ozone layer and the rise in temperature.
 
These are the different types of renewable energy:

Geothermal energy

The earth, generous as it is, did not want to leave Man to his own devices: it puts at his disposal a hidden energy reserve, better known under the term geothermal energy. Very simply, geothermal energy is the exploitation of the heat stored in the subsoil, either for the production of electricity or heat.

Wind energy

What would a living being be without the wind? Absolutely nothing. Therefore, in addition to guaranteeing the survival of all living species, the kinetic energy of the wind is an inexhaustible source. Whether mechanical or electrical, this type of renewable energy is “decarbonized”, meaning that its greenhouse gas emissions are minimal, especially during the operation phase. Another great plus is that the size of the wind turbines can vary according to the energy needs.
 
Hydraulic energy
 
Hydropower
 

Produced from the movement of water, it is the most important source of renewable energy by producing 19% of the electricity. Knowing also that it is drawn from all existing water sources (the sea, groundwater, rivers …) this inexhaustible energy not only fights against the waste of water but also does not emit any greenhouse gas. The advantage of this renewable energy also lies in its speed of use, it is enough to have the volume of water and the necessary pressure. The more movement and force there is, the more electricity will be produced. As simple as that.
 
Solar energy

Without surprise, we guess that solar energy means the energy produced by our good old star of the day. This type of energy is not very complicated, the energy of the sun is captured by what we call photovoltaic panels, or simply solar panels and is directly converted into direct electric current, then an inverter reconciles the electricity into alternating current that it distributes in the network whose quantity is then measured by a meter.
 
The great advantage of this type of renewable energy is that as long as the sun continues to shine, wherever we are in the world, solar energy will never dry up, so we are safe for some 4.5 billion years.

Biomass

Let’s talk about the energy produced by animals and plants. Biomass is probably the oldest renewable energy used by man. It consists in transforming materials of biological origin into heat, electricity and fuel by combustion or mechanization. We distinguish three main families: solid biomass or wood energy biogas biofuels
The transformation of wood is another type of renewable energy, but not the only one. Other residues such as straw, corn bunches, sugar cane and olive-pomace are also sources of energy.

One can imagine the questions on the environmental repercussions in relation to the forest harvesting and the natural growth of the trees, even if for the moment there is not too much to worry about. In France, as elsewhere, we take fewer trees than we grow. Phew.

This energy supplier is already on the market, for companies and individuals, as much for wood as for other fuels.
