While Donald Trump’s administration is pedalling back on American commitment to green energy, China is rapidly expanding renewable energy across its vast landscapes, building huge solar and wind installations to reduce reliance on fossil fuels. In some desert regions, solar panels are not only providing shade but also slowing land degradation, giving farmers renewed hope. The country now produces more solar panels than the rest of the world combined and aims to peak emissions by 2030 and reach carbon neutrality by 2060. Yet the transition brings tensions. Oversupply has hurt manufacturers, while some rural communities lose farmland or feel excluded from decisions. Concerns also remain about labour practices and environmental impacts linked to mining and construction. At the same time, coal still supplies much of the nation’s electricity, meaning the shift must balance economic growth with environmental responsibility. The changes show both promise and hardship as society adapts to a new energy future.

‘Sand batteries’ could be a key breakthrough in storing solar and wind energy all year round. Solar energy stored in sand batteries could help get Finns through the long cold winter, which is set to be even tougher after Russia stopped its gas and electricity supplies. The new technology has been devised by young Finnish engineers Tommi Eronen and Markku Ylönen, founders of Polar Night Energy. This innovation could be used worldwide. Whilst a number of other research groups are testing the limits of sand as green energy storage, the pair are the first ones to successfully rig it to a commercial power station.
