What are the cons of renewable energy?

Advantages and disadvantages of renewable energies pdf

Renewable vs. non-renewable energies but… What do we mean by renewable and non-renewable energies? We often refer to clean energies as those that come from natural sources and can last over time (are sustainable).

It is no secret that humans have had a serious impact on the earth’s climate. Much of this influence has been carried out by the use of non-renewable energies such as coal or oil.

In tus Placas Solares we work in a specialized and professional way in renewable energy projects, especially solar. Solar energy can generate electricity or heat water, through solar photovoltaic panels or solar thermal panels. This translates into savings even without incentives or aid from the government or Junta de Andalucía for solar panels 2020.


Renewable energies are the present and the future of global electricity production. The term captures the essence of this type of energy, embodied by its availability in nature and its capacity for continuous regeneration, without human intervention, spontaneously and in inexhaustible quantities.

They are those that are obtained from natural sources and are inexhaustible or with a capacity for renewal. These energies have become a key part of achieving the Sustainable Development Goals (SDGs) and the goal of achieving the sustainability of the planet. They include solar, wind, hydro, geothermal, tidal, wave, biomass and biogas.

Producing renewable energy means using the sun, the power of the wind or water and the earth’s heat, which are abundant and widespread in nature, to generate electricity. Energy that, compared to that produced by conventional sources, is capable of drastically reducing emissions levels.

Advantages and disadvantages of conventional energies

But are there only advantages to the adoption of renewable energies in Chile, or are there also negative aspects to be taken into account? To have a broader view, it is necessary to first understand what renewable energies are and what is behind their operation.

They are those energies coming from sources that are naturally replenished or virtually inexhaustible. These sources are the so-called “renewable resources”, which are considered inexhaustible in duration, either because of the immense amount of energy they contain, or because they are able to regenerate at the same rate at which they are being consumed, unlike coal or oil.

Arguably, the main disadvantage of solar and wind power plants is their intermittency. These plants do not deliver constant energy, so it is still necessary to produce energy from fossil sources when NCREs are not producing, or to use previously stored energy from some other source.

For example, during the night, when electricity is most in demand for lighting and heating, solar power plants do not generate energy, so it is necessary to use thermal power plants, for example, to supply the base energy.


The advantages and disadvantages of solar energy refer to the benefits and risks of using technologies to capture and use light energy from the sun. of all the solar energy that reaches the Earth:
