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. 

Up to a quarter of Europe's energy needs come from Russian imports. Faced with possible supply cuts in the wake of the invasion of Ukraine, the EU has come up with a plan. It aims to end its dependence on Russian oil and gas through energy efficiency, renewable energies and diversification of supply.
