El biogás. Actualidad y perspectivas de un gas renovable

Biogas. News and perspectives of renewable gas


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.


11th Home Energy Efficiency Index


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

The role of “g-mobility” in the current transport system


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.


Designing eco-cities


This article introduces the concepts of eco-city and eco-design. They are tools applied to move current cities towards this new, more sustainable city model. The article also describes some experiences of eco-design in urban settings. These experiences are classified according to the territorial scope and the flow they are involved in. The territorial areas or systems selected are: public space in which both the underground and the above ground part, the building and the neighbourhood are affected.
