Which is the most used renewable energy in the world?

Renewable energies

Renewable energies are understood as all those that come from a natural source, are clean and almost inexhaustible resources. There is a wide variety of renewable energies, but in general they are distinguished according to the final energy obtained from them. We highlight electrical energy, thermal energy and biofuels.

If we look at the total electricity generation from renewable energies, we see that 66.8% corresponds to wind energy. This is followed by photovoltaic solar energy with 11.2%, mini-hydro with 8.2%, thermoelectric solar with 7.1% and biomass with 6.7%.

Thus, the EU heads of state and government, represented at the European Council, agreed in 2014 that by 2030 the share of renewables should rise to 27% at EU level.

On November 28, 2017, the European Parliament’s Energy Committee endorsed changes to the Renewable Energy Directive. The amendments include a more ambitious target of 35% for renewables by 2030.

The vast majority of the world’s scientific community agrees that the main threat to the planet’s equilibrium is anthropogenic global warming, and that the main factor contributing to this complex situation is the use of fossil fuels en masse as the main source of energy.

This is the most widespread renewable energy and one of the oldest. It consists of harnessing the power of water courses to generate electricity by means of turbines, generally through the creation of dams.

Hydroelectric power currently produces 16% of the world’s electricity, and 65% of that from renewable resources. However, it is important to consider the potential negative impact of dams, both environmentally and culturally.

The sun is the basis of the third largest renewable energy source and one of the most diversified in the world. Among its most common forms are photovoltaic and thermoelectric energy, although there are many variants.

Percentage of renewable energy use in the world 2020

Renewable energy is energy that is obtained from virtually inexhaustible natural sources, either because of the immense amount of energy they contain, or because they are capable of regenerating themselves by natural means.[1] Renewable energy is obtained by means of wind turbines that harness the kinetic energy of the wind, transforming it into electrical power.

The energy is obtained by means of wind turbines that harness the kinetic energy of the wind by transforming it into electrical energy. This resource can be described as perpetual, and the amount potentially obtainable in a given geographical area depends on the wind regime and the orography of the site.

A similar, but not identical, concept is that of renewable energies: an alternative energy, or more precisely an alternative energy source, is one that can replace conventional energies or energy sources,[2] either because of its less polluting effect, or fundamentally because of its possibility of renewal.

Energy consumption is one of the great gauges of a society’s progress and well-being. The concept of energy crisis appears when the energy sources from which society is supplied are exhausted or become drastically more expensive. An economic model such as the current one, whose functioning depends on continuous growth, also requires an equally growing demand for energy. Since fossil and nuclear energy sources are finite, it is inevitable that at a certain point the demand cannot be met and the whole system will collapse, unless other new methods of obtaining energy are discovered and developed: these would be alternative energies.

Renewable energy statistics in the world 2019

Renewable energies are those that are obtained from natural sources and are inexhaustible or renewable. These energies have become a key part of achieving the Sustainable Development Goals (SDGs) and the goal of achieving the sustainability of the planet. Among them we can find solar, wind, hydro, geothermal, tidal, wave, biomass or biogas.

This type of renewable energy consists of harnessing electromagnetic radiation from the sun by means of photovoltaic cells, solar collectors or heliostats. Solar energy itself can be photovoltaic or thermal. The difference is that photovoltaic solar energy produces electricity directly from solar radiation. While thermal energy consists of taking advantage of solar energy to produce heat.

Solar energy is one of the renewable energies with the greatest potential for development, since the sun can be used to a greater or lesser extent as a source of energy anywhere on the planet. One of the key milestones for understanding the development of solar energy dates back to the 1970s, when the oil crisis led to the search for alternatives to reduce the price of crude oil.
