Why is energy renewable?

Examples of renewable energies

Renewable energies are those that come from sources considered inexhaustible, and which are characterized because in their transformation and use processes they are not consumed on a human scale, either because of the immense amount of energy they contain or because they are capable of regenerating themselves over time. Among these energy sources are hydro, solar, wind and ocean energy. Similarly, depending on how they are exploited, energy from biomass, geothermal energy and biofuels can also be classified as renewable.

Our country has confirmed its leadership in renewable energies. We have the highest solar radiation in the world, strong winds from north to south to develop wind energy, a tremendous marine energy potential on our coasts, great capacity to develop biogas and a geothermal resource along our mountain range.

This is mainly due to the record investment in non-conventional renewable energy projects (NCRE), which has more than doubled: jumping from 1.3 billion dollars in 2014 to 3.2 billion dollars in 2015. The ranking considers four variables: enabling framework, investment, value chain and CO2 reduction.

Non-renewable energy

Renewable energies are those obtained from natural sources that produce energy inexhaustibly and indefinitely. For example, solar energy, wind energy or tidal energy are renewable sources of energy. They are also considered renewable when they are obtained from sources that regenerate naturally over time, such as forests.

One of the main advantages of renewable energies is that, in addition to being inexhaustible, they have little or no negative impact on the environment, so they are considered clean energies. Renewable energies are currently a reality in our society and their benefits for the environment are more than evident.

Every society on the planet consumes energy to a greater or lesser extent, but the reality is that most of the energy consumed comes from non-renewable sources, such as fossil fuels and nuclear energy, which have a greater negative impact on the environment. A noteworthy aspect of renewable energies is that they can be applied and exploited at the local level, which helps to reduce the dependence of populations on large energy producers, favoring economic development and job creation.

Clean energies

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.

Renewable energy characteristics

Unlike conventional energy sources, renewable energy sources are those that we find in nature in unlimited quantity, that can be regenerated naturally or artificially and whose impact on the environment is practically null or reversible. Renewable energies include hydroelectric, wind, solar, geothermal, tidal and biomass energy.

Due to these advantages, the production of this type of energy has been supported by the international community through the signing of the Paris Agreement signed during the World Climate Summit held in 2015 in the capital of France. This agreement, which will be in force as of 2020, establishes that the 200 signatory countries will reduce their greenhouse gas emissions to avoid the most dramatic effects of climate change.
