Wind energy becomes the main energy producer in Spain in 2021, surpassing nuclear

There are still a few days until the end of the year but the data does not lie: this year wind energy will be the main source of electricity supply in the country, ahead of nuclear.

And it is that, so far this year, there have been up to 64,053 GWh of wind energy in front of 56,343 GWh from nuclear, assuming almost a quarter of the energy produced and leaving behind the rest of sources and favoring that the generation of clean energy in Spain is increasing.

Almost half of the energy produced in Spain comes from renewables

During the 11 months that we have been in the year and with a few weeks until the end of 2021, wind energy has been responsible for the 24% of energy production in Spain, doubling hydraulic, surpassing nuclear for the first time.

The third source of energy in Spain has been the combined cycle, a technology that combines a gas turbine and a condensing steam turbine in a way that increases efficiency, in this case for large power plants that produce electricity. In other words: natural gas.

During 2021, renewables have produced 47.3% of energy, increasingly close to the dirtiest energies and practically half of the country’s demand.

That wind energy is positioned as the main source of supply for the country shows how the commitment to clean energy is being effective.

Since, renewable energies are still behind in the generation of electricity at the national level, but during the year it has been seen as on some occasions, clean energies have been the main source of supply in the country.

Little by little, Spain is distancing itself from the most polluting energy sources, albeit with brush strokes.

While the nuclear power plants are expected to gradually close down, by the year 2035, the great electricity demands of recent months have led to the As Pontes coal power plant being re-ignited, as the latest cold waves have needed support of this energy to be able to cover the necessary demand.

It is true that the use of this energy source only accounts for 1% of all electricity produced.

Last month and during the COP26 Climate Summit, an agreement was reached to suppress coal as an energy source in what was a joint declaration where they commit to end international public support for the fossil fuel energy sector to end of 2022 and prioritize support for clean energy transition.
