Solve your doubts about green electricity


The use of the term green electricity or green energy is becoming more frequent  . The electric companies begin to offer the hiring of this type of energy and there are more individuals and companies, sensitized with the care of the environment, who acquire it. 

But what does the term green energy mean? How does this energy reach homes or businesses? Can I be sure that the electricity I contract is 100% renewable ? Is more expensive? 


What is it?

Green energy is understood as one that comes exclusively from 100% renewable and inexhaustible sources (wind, solar, hydraulic, biomass, geothermal …). Greenhouse gases, in particular CO 2,  and other polluting gases are not emitted in the green electricity production process , unlike the energy produced through the combustion of fossil waste (coal, gas, or oil).


How do you get to homes or businesses?

The electricity produced (green or conventional) in the different generation plants is poured directly into the distribution network . From that moment, the energy is indistinguishable, it can not be differentiated that which has a renewable origin from that which does not.


However, when a consumer contracts with his commercializadora green electricity , what is guaranteed is that the same amount of electrical energy that will consume in your home or company, will have been generated from renewable sources and, therefore, will have been avoided the pollution of the environment.


What guarantees are there that it is 100% renewable?

Throughout the European Union there is a mechanism called System of Guarantees of Origin (GdOs) and Labeling of Electricity. In Spain, the National Commission of Markets and Competition (CNMC) is the regulatory body that issues Guarantee of Origin certificates , which certify the amount of renewable energy generated by a producer of electricity for a full year. 

The green energy producers transfer these Guarantees of Origin to the trading companies so that they, in turn, can sell the green energy and the end user can contract it. We can consider that the system is safe, because the official agencies in charge are concerned with recording each transfer of certificates to avoid double counting. 

Any consumer who decides to contract green electricity can check the guarantee of the origin of said electricity, by entering their CUPS (unique number for each supply point that identifies it, appears on the electricity bill) and fiscal identification (NIF or CIF) directly in the web of the CNMC .

This way you will have the certainty that you are producing a quantity of renewable energy equivalent to the one you are consuming.


Is more expensive?

As in the case of conventional electric power, the types of rates that can be contracted in the renewable energy sector are many (rates for companies or individuals, tariffs with or without hourly discrimination …). Recruitment can be done well with large traditional companies or with small traders and renewable energy cooperatives that are dedicated solely to the commercialization of this type of energy.

Depending on the selected marketer and the type of tariff, a final price will be obtained. In any case, the rates  do not have to be more expensive than the conventional ones and have the advantage that with their hiring they contribute to the care of the environment.


What implications does it have?

Currently, the demand for green energy in our country is much lower than what is actually produced. In Spain, during 2016, 41.1% of the generated energy came from renewable sources. If the demand increased and approached the supply, electricity producers would probably opt for new renewable energy production plants which, in turn, would imply a lower demand and production of conventional, more polluting electric energy. 

Knowing all this about green energy … What is your choice as a consumer?

Do you join the change?
