Hundreds of photovoltaic cells, groundwater wells and heat pumps. These are some of the features shared by some net-surplus-energy buildings: those capable of producing more energy than they consume.

For years, the sun, wind and water have been used to generate electricity. Now researchers in Japan are experimenting with a new renewable energy source: snow. The plan is to exploit temperature differences to help ease energy supply problems.

Using skyscraper lifts to store energy when there's a surplus and generate it when it's scarce. That's what a team of researchers aims to achieve with a new gravity-based system, details of which have been published in the journal Energy. We analyse the potential and the limitations of this technology.

Gonzalo Sáenz de Miera, Director of Climate Change and Alliances of Iberdrola, explains the main action lines Iberdrola has put in motion to fight against climate change and how innovation is a key element to achieve those goals. 

Reducing the impact of the transport sector on air quality, natural habitats and climate is one of the challenges of this century. Although LNG is presented as an alternative for more sustainable transportation, it comes with a major drawback: it generates greenhouse gas emissions and contributes to global warming.
