Lately we have been hearing and talking about the term Renewable Energies as one of the main ways to tackle climate change and achieve the fight against decarbonisation. Since these are energies that use natural resources such as the sun, wind and water, they do not pollute our planet.


Despite all the benefits of renewable energies such as solar and wind, there are many who remain suspicious due to the many myths and hoaxes that are told about them. But… Are these truths true? We talk about it.

  1. They are more expensive than conventional energy.

This is one of the most repeated and heard, but the reality is that the opposite is true. Thanks to the increase in demand, as well as the advance of new technologies, the prices of renewable energies are increasingly lower. In fact, according to a study carried out by IRENA (International Renewable Energy Agency), solar and wind energy are among the cheapest in the world. Moreover, it should also be taken into account that these energies do not have as high maintenance costs as polluting energies.

  1. They are not able to cover all the needs of consumers and need the support of other energy sources.

Renewable energies are indigenous and this provides security of supply and economic development. As more and more governments and citizens are becoming aware of the climate crisis, demand for them has increased in recent years, and they are able to cover the needs of a country’s inhabitants.

  1. They are harmful to the environment (landscape and biodiversity).

The impact of renewables on the landscape is a subjective issue that is difficult to measure, as it is an aesthetic impact. In this case, only protected natural areas or areas inhabited by endangered species should be avoided. On the other hand, wind energy is accused of causing damage to wildlife, but this can be avoided with a prior study of the migratory routes that may be affected. On the basis of this study, it can be seen where to locate a wind farm or not.

  1. They pollute more than fossil fuels.

Renewable energy sources are 100% environmentally sustainable, do not produce emissions and are inexhaustible, so they do not pollute more than fossil fuels. Moreover, international experience has shown that their use is more beneficial and fairer for everyone.

There are undoubtedly many demonstrable and proven advantages of renewable energies. They are safe, environmentally friendly and the best option available to mankind to meet its energy needs.
