A return to coal in Spain is not feasible in the short term, as many of the old thermal power plants have been dismantled. In the long term, the future of electricity production lies in renewable technologies, not only because of their environmental implications, but also because of energy independence with respect to third countries. In the short term, it is essential to continue using conventional technologies.

A study published in the journal Communications Earth & Environment (from Nature Research) estimates that a reduction of 686 million tonnes of carbon emissions could be achieved each year if the world followed a cycling pattern similar to that of the Netherlands (2.6 kilometres per day). This is about 20 % of the carbon emissions produced by the global passenger car fleet in 2015.

The Council of Ministers on Monday approved a package of urgent energy efficiency and energy saving measures, including limiting the thermostat on air conditioning and heating in transport, workplaces and shops.

Last week, the European Parliament approved a ban on the sale of vehicles with emissions of more than 0 grams of CO₂ per kilometre from 2035 in Europe. In addition, they also voted against an amendment that would allow car manufacturers to buy credits for so-called synthetic fuels. Is this the right measure to accelerate the decarbonisation of the transport sector?

The current climate crisis is not only leaving us with a historically warm winter and a decade of record temperatures, but is overlapping with an almost unprecedented energy crisis. Securing energy supplies in a sustainable way is now a challenge where the war in Ukraine adds to the complexity.

The Joint European Torus (JET) has achieved a relevant scientific milestone related to energy production from nuclear fusion reactions. The results confirm some of the technological options selected for the large international ITER experiment. Spain has proposed to build a scientific facility in Granada to develop materials with which to build future reactors.

The dream of obtaining electrical energy from the fusion of two atomic nuclei is a little closer. Results obtained with some of the most powerful lasers on the planet show that one of the strategies to achieve this, nuclear fusion by inertial confinement, works as predicted 50 years ago.
