Green energy is not the energy of the future is the energy of the present

Solar, wind, hydro, biomass or geothermal… Green or renewable energy can come from different sources: however, its production process must also be ‘green’,  mean, it must not involve the emission of greenhouse gases (especially CO2), in addition to other polluting gases.


When it comes to producing other fuels, for example, those obtained through the combustion of fossil wastes (coal, gas or oil), these polluting gases are generated, unlike green energies.

In order for green energy to reach your home, it must pass through the usual distribution network, mixing with the rest of the energy produced by other means. However, your marketing company guarantees that the same amount you consume in your home or business has been generated from renewable sources.

The European Union ensures that this is the case through the System of Guarantees of Origin (GdOs) and Electricity Labelling. For its part, in Spain, the National Commission of Markets and Competition (CNMC) is responsible for issuing certificates of Guarantee of Origin, which confirm the amount of green energy generated by a producer for the space of one year. The CNMC website offers consumers the possibility of verifying that the energy they consume is indeed green.

Within the framework of the EU, the rate of renewables in gross energy consumption in the European Union (EU) in 2017 reached 17.5%, half a point more than the previous year and double the 8.5% corresponding to 2004, the first year in which Brussels began to measure this parameter, according to Eurostat data.

Focusing on Spain, Eurostat places green energy consumption in 2017 at 17.4%, one tenth below the European average. Looking to the future, the Strategic Framework for Energy and Climate places the percentage of green energy consumption in 2030 at 42%.

The plans of large Spanish energy companies are to invest in renewables. Thus, by 2020, Nartugy will allocate 955 million euros to renewable energy to grow 1GW, 82.2% over its current production.  Endesa’s investment in renewables stands at 2,000 million euros to reach 1,900 MW in 2021. To this scenario must be added the emergence of Eleia, which will produce exclusively green energy and aims to reach 4,500 MW in 2022.
