Advantages and disadvantages of renewable energies


When the use of renewable energy is analyzed, there are generally arguments that widely support it for its benefits for the planet. However, they are not being used to fully replace non-renewable energy. That said, what are its advantages and disadvantages?

It is necessary to know in detail the advantages and disadvantages of renewable energy. To make this assessment, we will present both aspects below.

Advantages of renewable energies

They are often called clean energies due to their characteristics. Its main advantages are:

  • They generate less pollution than non-renewable energies. Therefore, the harmful effects on the health of the population due to pollution are practically nil.
  • Reduces the carbon footprint.
  • They will not be depleted because they come from unlimited sources. Therefore, they do not depend on the decrease in reserves over time.
  • They are less affected by geopolitical conflicts due to the exploitation of unique deposits in specific countries.
  • They do not depend on large fluctuations in prices due to the discovery of new deposits or the depletion of others. Something that does happen with fossil fuels such as oil that can promote speculation in the markets.
  • They are well received by the general public opinion.
  • They stimulate self-consumption.
  • They can reach remote places on the planet.
  • It can help reduce energy dependence.
  • They do not require exploration like fossil fuels or water sources, which implies assuming lower costs and risks.

Disadvantages of renewable energy

But not everything is positive, there are also risks that are also worth exploring in order to make an objective analysis. So the main disadvantages are listed below:

  • They depend on atmospheric phenomena. For example, in some cases they depend on the Sun or the wind blowing at a certain intensity to ensure the supply of energy to a certain population. Therefore, if only renewable energy was used at this time, the energy demand would not be fully assured for any country.
  • In some cases, such as the generation of solar energy, it requires a large space.
  • It requires a greater investment because in many cases it is not yet on the market.
  • In some cases it is not easy to carry out its storage, so it is necessary to consume at the moment.
  • Not all latitudes on the planet have the same natural resources. Therefore, it is impossible for all countries to obtain the same amounts and types of energy. Something, let it be said, that would force them to continue making use of another type of energy to satisfy their energy needs.
