Challenges to renovate energy efficiency in Spain

 in the category Blog en, Blog news, news, Press room

At the present time, most of the countries of Europe, and especially Spain faces one of the biggest challenges of the 21st century. It’s about the transformation of the energy efficiency of our country.

We already know that we are destined for switching to renewable energies, firstly for running out of the conventional resources for the energy obtention, and then for the fact of being able to enjoy four seasons without having to support constant scourges of ciclogénesis that do not correspond to the normal behavior of the environment.


According with the RISE report (Regulatory Indicators for Sustainable Energy) made by the World Bank, of 111 treated countries, and the analysis of key factors as they are the investment in renewable energies, energy efficiency and the access to the energy, Spain fills the 22th place. And the fact is that we have some characteristics that affect us to a larger extent (and others in lesser extent) than other leading countries in these terms. The exterior energy dependence (77,4 %) or the conventional models of consumption based on non-renewable energies are an example of it.

Hereafter we sum up to you briefly the energy picture of last times in Spain with three very revealing details: industry is the main authoress of 25 % of the whole energy consumption, the energy intensity (lack of productivity) is superior to the European average and finally, 57 % of the whole demand stocks up with gas or oil, that is to say, non-renewable energy.

It’s interesting (and already necessary) to bring the discussion on the intervention of new technologies, and to begin speaking about Industry 4. 0, a concept that implicitly takes  the change in the productive models. On the part of the industry, the challenge comes from the increase of energy demand and the decrease and prohibitions of non-renewable material. And on the part of the consumers, to take conscience of the energy waste, whether by the fact of poor energy efficiency, or for the unnoticed use of the same one.

The energy companies cluster is clear about it, the technologies have to bring new processes capable of providing with better services to the clients, guiding them towards the demand requests and to the adjustment of supply and demand  in real-time of it. All of this, they’re trying to obtain it by means of development and implantation of new management systems, based on the last technological trends: Big Data, Cloud Computing, or the Internet of Things (IoT). The combination of new energy audits together with the application of this information, they will lead us to new models that monitor the consumption and the demand behaviour.


Spain has set its targets of energy efficiency based on the targets of the European Union. From the targets set in 2007 by the European Council on the subject of increasing renewable industries and greenhouse gases reduction, even further than the well-known block 20/20/20. Unlike these, those energy efficiency measures aren’t of mandatory for the member countries, at least at this moment.

Although this Energy Savings and Efficiency Acton Plan of the EU is only about advices, it’s necessary to bear them in mind.


Between the bundle of measurements that are described, one explains the decrease of energy cost by means of the activities’ implementation to increase the energy efficiency.

At present most of the renewable activity is partly complemented with the fossil energy, and we can only see big successes of energy selfconsumption in particular housings, without connecting to the electrical network (off grid). Probably the blame of encountering that in neighbours’ communities this type of supplying is not established should be put on the extra tax that supposes having these elements connected to the network, since up until now, no energy for sale available individuals is profitable to be able to cover the demand of an entire community.


To be able to guarantee a balanced tuning between the cost and the productivity, it’s essential the factors: use of the energy and also the access to this one. In a rural environment, with seemingly adverse climatology and that ironically gives in for lack of resources, is where more easily we will find renewable and abundant energy, another extra thing that the big city will never be able to provide us with.


The real challenge of the transformation of the energy efficiency in Spain is to find a valid answer for all the agents that intervene directly or by implication in the energy sector. They are public administrations, companies and citizens… All of them with different interests but with a common and an unavoidable target, working to obtain a better energy efficiency. This has to take implicitly the inclusion of measurements of environmental campaigns to raise public awareness so much on the part of the public administrations and on the citizens.
