CLEAN AND RENEWABLE ENERGY

A topic that is increasingly discussed today, clean energy is all about electricity generated through renewable sources and without the emission of pollutants or impact on the environment.

Climate change and global warming make this an issue fundamental for the whole society. Nowadays, the best known representatives of this type of generation are solar and wind energy.

Types of clean energy

The most used energy sources are the waters of rivers and oceans, winds, sunlight, biomass, waves and tides and heat from Earth.

And all are available to a greater or lesser extent for everyone.

Wind energy

Produced by propellers fixed on top of high towers that rotate according to the intensity of the winds, generating energy through the driving force of the turbines.

This technology is more mirrored in centralized generation due to its availability and is more restricted than sunlight.

Solar energy

It allows the generation of electric energy through two types of technology: photovoltaic and heliothermic.

Photovoltaic consists of the transformation of solar radiation directly into electric current through photovoltaic cells, which make up the modules exposed to sunlight. This technology already exists in millions of homes and businesses around the world through the so-called photovoltaic systems connected to the network that integrate distributed energy generation.

The heliotérmica uses several collector mirrors that reflect, in a concentrated, sunlight to a specific point in a large central tower, heating specific materials at high temperatures that, with their expansion or vaporization, drive turbines that generate electricity.

Renewable energy sources, mainly solar and wind, gain increasingly stronger as countries around the world invest in their use in the search to increase its options of energy sources that pollute less.

A very positive side is that the more these types of technologies, the lower the production costs become. Solar energy, for For example, it has already become the cheapest form of electricity generation in many places.
