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.

In the midst of a series of global crises—energy, climate and political—many powers have strengthened their commitment to nuclear energy. Although this type of energy aims to reduce greenhouse gas emissions, it suffers from the same old drawbacks: high costs and the need to manage the radioactive waste. Have we learned to control its risks?

Revolutionary inventions such as the compact disk, high-definition television and 3D printers have been unveiled at the CES trade show over the past few decades. We analyse the gadgets and technological trends that will likely gain momentum in 2022, according to the announcements made at the latest edition of the biggest technology fair in the world, which has just been held in Las Vegas.

In 2012, two incidents in India left almost 10% of the world's population without power. Nearly a decade later, the idea has become widespread that we could be entering an era of major power outages, even on an international scale. Is there any basis for this concern? In search of answers, we look back at some historic blackouts that affected millions of people for hours, days and even months.

Eliminating fossil fuels to combat climate change is one of the great challenges of the 21st century. What if the solution were to recreate the Sun on Earth? The ITER project seeks to construct the world's largest nuclear fusion reactor to achieve a clean, inexpensive and inexhaustible source of energy.
