Renewables win the game

19 January 2017

The former constitute the set of Non-Renewables, which means that their consumption progressively decreases their resources and can reach its extinction.

The sources that supply the energy that constitutes our daily reality, are basically divided into two types:

  • On the one hand, oil, gas, coal, (called fossil energies from animals and plants buried millions of years ago) and nuclear energy.
  • On the other hand, the energies that are obtained from the seas, rivers, winds, sun, and organic waste (biomass).

The former constitute the set of Non-Renewables, which means that their consumption progressively decreases their resources and can reach its extinction. This problem would not be present in the case of nuclear energy, which we know, presents other types of problems arising from its nature (Chernobyl, Fukushima ... besides the huge problem of nuclear cemeteries).

Although the sources of oil, gas and coal are far from being exhausted today according to the immense underground deposits that exist, given the huge quantities that are consumed it is thought that in the not too distant future, they can not constitute the backbone of the supply energetic. But the main problem with these energy sources is the current degree of environmental pollution they generate, increasing CO2 emissions, the reduction of the ozone layer, the emission of greenhouse gases and other problems caused by climate change. Given the current rate of consumption, very serious consequences for the planet and the human life that inhabit it are likewise conceivable, all in the short term. It is necessary to end this harmful (even lethal) self-consumption.
And the only way to find alternative solutions - and since the global energy needs, far from diminishing increase - is to promote the consumption of renewable energy.

Marine energy, river hydraulics, wind power and the two solar energies (solar thermal and photovoltaic) are exempt from all the previous problem of global pollution. They are CLEAN ENERGY. And they are called renewable, because it has to be considered that its duration is unlimited (the solar extinction is not predicted for an immediate future). Therefore they are SUSTAINABLE ENERGY. To all this we have to add advantageous arguments somewhat more prosaic at the national level, such as the reduction of spending by the purchase of CO2 emission rights, the reduction of energy dependence from abroad or the creation of jobs.

It would be enough to observe the path taken by Germany following the Fukushima accident in 2011, as regards the progressive increase in the percentage of renewables in its annual energy mix, in order to have a very reliable indicator of the way forward, especially considering the noticeable lowering In these last years of the cost of production in some of them and we specifically think in the photovoltaic.
That the renewables become the backbone of the energy system will be a huge challenge that will need to be addressed.
