Find out what the five major types of renewable energies are and what their specificities are.

There are five main types of renewable energies: solar, wind, hydro, biomass and geothermal. Their common characteristic is that they do not produce polluting emissions (or little), and thus help to fight the greenhouse effect.

Photovoltaic or thermal solar energy

Solar energy is produced by the sun's radiation. One distinguishes the photovoltaic energy which, as its name implies, transforms the energy contained in the solar radiation into electricity, solar thermal energy which, in turn, transforms this same radiation into heat.

The air at the origin of wind energy

The ancestors of windmills are windmills. Wind turbines generate energy, for example electricity, from the displacement of air masses.

Hydro power thanks to marine currents

Hydraulic energy is directly obtained by water, whether from dams, tides and currents, waves, or the encounter of fresh water and salt water. In order to remain renewable, the thermal energy of the seas, which derives from the difference in temperature between deep and surface waters, must be used with caution, in particular to avoid any disturbance of the natural flows of the seas.

Biomass energy from organic matter

Biomass energy includes wood, biofuels (from plants such as rapeseed or beetroot) or biogas. This energy is produced by burning or metabolizing organic matter.

Draw energy from soil, geothermal energy

Geothermal energy is a renewable energy derived from the extraction of the energy contained in the soil. It can be used for heating as well as for electricity production. It is one of the only energies not dependent on atmospheric conditions.

It should be noted, however, that for geothermal energy to remain durable, the rate at which this heat is drawn must not exceed the speed at which the heat travels within the Earth.

Renewable energies

Renewable energies (hydro, solar, wind, geothermal and biomass) are developing intensely throughout the world, driven by the need to combat global warming by reducing greenhouse gas emissions.

What is renewable energy?

An energy is said to be renewable when it is produced by a source that nature constantly renews, unlike an energy dependent on sources that are exhausted. Renewable energies are very diverse but they all come from two main natural sources:

• the Sun: emits radiation that can be transformed into electricity or heat, generates unequal temperature and pressure zones at the source of winds, generates the water cycle, allows plant growth and generation biomass;

• Earth, whose internal heat can be recovered from the surface.

The renewable nature of these energies, their low emission of waste, polluting discharges and greenhouse gases are advantages. But their power, relatively disseminated, is much lower than that of highly concentrated non-renewable energies. They can be - in the case of solar and wind - "intermittent" and hardly storable because they are immediately transformed into electricity, requiring then the punctual contribution of other energies. Their implementation also involves heavy investments, even if over time they become increasingly competitive in the face of fossil fuels.
