When was renewable energy started?

History of renewable energies pdf

Hydropower, wind, solar, biomass and geothermal energy are clean and inexhaustible energies. As renewable energies, they play a predominant role in the energy transition. It is therefore essential to promote their development to combat climate change.

An energy is said to be renewable when its energy source is based on the use of natural resources, such as the sun, wind, water or biomass. Renewable energy is characterized by the fact that it does not use fossil fuels, but natural resources capable of unlimited renewal.

In addition to being inexhaustible energies, they do not produce greenhouse gases (GHG), the main cause of climate change, or pollutant emissions, so they have a very low environmental impact. It can be said that renewable energies are clean energy sources.

Why is nuclear energy not renewable? Nuclear energy is a decarbonized and non-polluting energy. It does not emit greenhouse gases into the atmosphere. However, uranium, the fuel used in nuclear reactors, is a limited resource. Therefore, nuclear energy is a clean but non-renewable energy.

When renewable energies were created

Renewable energies are those that come from sources considered inexhaustible, and which are characterized because in their transformation and exploitation 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.

Clean energies

Renewable Energy is the energy 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.

The use of renewable energy sources by man is very ancient. Since many centuries before our era, renewable energies such as solar, wind and hydro were used by man in his domestic, agricultural, artisanal and commercial activities. This situation prevailed until the advent of the First Industrial Revolution in the 18th century, when renewable energies had to give way to fossil resources such as oil and coal, which at that time were offered as abundant and cheap sources of energy. The industrial revolution also triggered the social and economic changes that led to the subsequent development of the large hydroelectric industry, now considered a conventional renewable energy source.

Nowadays, when the availability of fossil resources plays a determining role in the global and national energy supply, and when environmental factors appear among the main concerns of contemporary society, Renewable Energies are re-emerging with increasing success in all latitudes of the planet, encouraged by the constraints of energy supply and the presence of favorable regulatory frameworks.

Who invented renewable energies

– In Distributed Generation, the CELs meant an opportunity to reduce the investment return periods of solar panel users throughout the country, thus promoting the growth of medium scale projects, generating jobs, development and clean energy for all with new investment and new generation capacities.

– The modification of the guidelines for the allocation of clean energy certificates will devalue the value of the certificates, as it allows CFE to be recognized CELs for energy generated with legacy plants, when the objective was to generate clean energy with new plants.

– In medium-scale distributed generation, there are more than 2,200 projects that, due to their size, were seeking to accredit CELs and thus have an extra income from clean energy generation; there are also new projects that were also thousands and are being held back due to the uncertainty of the return on their investment.

– In fact, this will delay investments, affect those already made and dozens or perhaps hundreds of distributed generation projects in the country will be delayed, reducing the income of the installers and therefore that of their families, affecting the energy market and the environment.
