RENEWABLE ENERGY
In this section we will present what renewable energies are, the types and technologies that we can find on the market.
Renewable energy is energy that comes from natural resources such as sun, wind, rain, tides and heat, which are renewable (naturally replenished).
Sustainable development
O desenvolvimento que procura satisfazer as necessidades da geração actual sem comprometer a capacidade das gerações futuras de satisfazerem as suas próprias necessidades. Significa possibilitar que as pessoas, agora e no futuro, atinjam um nível satisfatório de desenvolvimento social e económico e de realização humana e cultural, fazendo, ao mesmo tempo, um uso razoável dos recursos da terra e preservando as espécies e os habitats naturais.

Sustainable development
Development that seeks to meet the needs of the present generation without compromising the ability of future generations to meet their own needs. It means enabling people, now and in the future, to achieve a satisfactory level of social and economic development and human and cultural fulfillment, while making reasonable use of the earth's resources and preserving species and natural habitats.

WATER
Water energy comes from the movement of water. It is produced by taking advantage of the hydraulic potential existing in a river, using natural unevenness, such as waterfalls, or artificial ones, produced by deviation from the original course of the river.

Solar energy is that which comes from the Sun (thermal and light energy). This energy is captured by solar panels, hydro energy comes from the movement of water. It is produced by taking advantage of the hydraulic potential existing in a river, using natural unevenness, such as waterfalls, or artificial ones, produced by deviation from the original course of the river.
SOLAR
Solar energy is that which comes from the Sun (thermal and light energy). This energy is captured by solar panels, formed by photovoltaic cells, and transformed into electrical or mechanical energy. Solar energy is also used, mainly in homes, to heat water.

WIND
Wind energy is the kinetic energy contained in moving air masses (wind). The use of this resource is done by converting the kinetic energy of translation into kinetic energy of rotation, using wind turbines, also called wind turbines, for generating electricity, or windmills (and windmills), for mechanical work. like pumping water.

BIOMASS
Biomass refers to natural residues and residues resulting from human activity. Biomass can be used directly as fuel or through its biodegradation to produce a combustible gas, called biogas. In either situation, the heat produced can be used directly for heating or for the production of steam that will drive a turbine to produce electricity.

WAVES AND TIDES
Wave and tidal energy comes from a renewable energy source that results from the transformation of energy contained in sea waves and tidal waves into electrical energy. This type of technology, although not commercially available, has been developed since the 1970s in a number of countries with the potential to exploit this type of energy.

GEOTHERMAL
Geothermal energy is the energy obtained from the heat coming from the interior of the Earth. The earth's heat exists in a part below the surface of the planet, but in some parts it is closer to the surface than others, which makes it easier to use. In certain places, drilling holes of just 100 meters it is possible to obtain useful heat, as well as there are areas where there are completely spontaneous hot springs.
