Why do we need renewable energy?

Renewable energy characteristics

Sustainable sources are experiencing a constant growth that will allow changing the paradigm of energy consumption. With zero environmental impact, they represent the future and are fundamental allies in the fight against climate change.

Turning on the light, opening the faucet or turning on the stove are indispensable actions in everyday life. Automatically and unconsciously, we never think about what is behind such simple movements.

Energy comes from various sources, categorized into two main groups: non-renewable and renewable. While the former are limited and pollute, the latter provide great benefits to the environment and are infinite. Among the renewable ones, there are solar, wind, biomass, tidal and hydraulic energies, which are available according to the geography of each territory.

The natural characteristics of our province position it as a favorable place for the development of clean sources, especially for solar energy, which obviously has the sun as its protagonist and gives rise to the other forms of energy on Earth. Barletta indicated that Mendoza is one of the areas with the highest solar radiation.

Advantages and disadvantages of renewable energies

Global temperatures are rising, creating major imbalances. From droughts to thaws, from species extinction to increasingly radical weather phenomena. Climate change is a risk for the planet’s ecosystems.

For example, in countries like the United States, almost a third of emissions come from the electricity sector. And most of these are generated by the use of non-renewable fossil fuels (such as coal or gas).

For example, in 1999, it was calculated how much CO2 was produced by solar electricity generation, taking into account the emissions of three countries. The result was just 50 grams per kilowatt/hour produced.

The most interesting thing about this is that, today, solar panels are much more efficient in generating electricity than in 99. In fact, even calculating the CO2 emission to also include the manufacture or installation of such panels, it is still minimal in comparison.

Renewable and non-renewable energy

There are many advantages that renewable energies are able to provide for the care and welfare of our planet, hence their great importance. If you are considering studying a master’s degree in renewable energies, you should know that you will be contributing to the care of the environment:

Betting on clean energy is to contribute to the energy of the present and the near future, so it is increasingly important to have professionals who have a master’s degree in renewable energy, professionals who are able to promote, manage, apply, analyze, know, understand and enhance the use of clean energy.

The so-called renewable energy sources (sun, wind and water) are those that can be used permanently because they are inexhaustible, unlike non-renewable sources (oil or coal).Tags: From an environmental point of view, we can speak of the existence of two types of energy sources: renewable and non-renewable.

Among the types of renewable or non-depletable energy sources are: solar energy, wind energy, hydroelectric energy, biomass and biofuels, geothermal energy and energy generated by waves, tides and ocean currents.

It is the energy obtained directly from the sun (which is, at the same time, the source of all renewable energies). Depending on the mechanism used, heat or electricity can be obtained.

Low-power wind power installations (as well as photovoltaic solar energy installations) enable any consumer to generate his own electricity, i.e. to generate his own electricity.
