Knowledge centre

Through the Knowledge Center you can access a wide variety of information and documentation on topics related to energy and the environment, sustainability, energy efficiency or industrial heritage. This virtual space created by the Naturgy Foundation puts at your disposal books, articles, papers, magazines, videos and material of disclosure for free.

Also, if you are interested in collaborating with our work, you can make your contribution to the Energy Rehabilitation Solidarity Fund.


The current project analyses energy taxation in the Spanish legal system. Therefore, it takes into account the regulation from the European Union and compares it with the regulation regarding those taxes that exist in the other countries around us. It also considers the extra-fiscal perspective, which is not different to environmental protection, one of the reasons behind energy taxation, as will become clear.

On 22 February, the cyborg anthropologist, Amber Case, launched a new series of conferences by the Naturgy Foundation, talkson, which encourage reflection on how humans and technology interact in the energy sector. “We shouldn’t have one all-encompassing online solution for everyone in customer relations,” said Amber Case. According to Case, customers must be aware of which electrical appliances increase their bill the most and how they can reduce the cost of heating and refrigeration in their homes so that they can “adopt measures in their consumption habits”.

El biogás. Actualidad y perspectivas de un gas renovable

The biogas produced, with an estimated available primary energy potential in Spain equivalent to 2.3 million tonnes of petrol a year, is a renewable and flexible fuel capable of covering heat, electricity and vehicular fuel demands. Upgrading to biomethane and natural gas grid injection favours its use wherever and whenever transformation efficiency is highest, even as a resource for the chemical industry, integrating geographically distributed production and consumption. Despite its multiple advantages, its present economy depends largely on energy prices and governmental policies in areas such as regional development, waste management, renewable energy and climate change, which allow economic evaluation of the multiple environmental benefits and favour the development of this new industry.


The Naturgy Foundation presents the latest edition of the Energy Efficiency Index for Spanish households, a study carried out since 2004 that makes it possible to identify the home energy behaviour and habits of Spanish citizens.

G-mobility Gas Natural Vehicular

By 2030, according to the EU’s road map for decarbonisation, the EU should have reduced its carbon emissions by 40% compared to the 1990 levels. For the transition towards this objective, the EU must continue promoting low-carbon, cost-efficient technology, taking action in all the sectors responsible for emissions in Europe. Nevertheless, the transport sector has not experienced the same gradual decrease in emissions as other sectors, therefore delaying the bulk of specific advances in emission reduction processes until the next decade. Today, mobility still represents almost a quarter of greenhouse gas emissions in Europe, and in urban areas it is responsible for increased atmospheric pollution.
