German discount supermarket chain Aldi has announced it will install 96,000 solar panels across more than 50 UK stores by the end of 2017. The panels will be added to the 85,000 units already installed across 275 stores and all nine of Aldi’s regional distribution centres, which generate more than 17,500MWh of electricity a year. The installations will take Aldi’s total store investment in solar to almost £17m, and will enable the retail giant to produce enough electricity to power the equivalent of more than 6,200 households.

For years, scientists have tried to emulate the process of photosynthesis. Finally, those efforts are blooming. The magazine Scientific American, together with experts from the World Economic Forum, has named the artificial leaf one of the breakthrough technologies of 2017. Laboratory-based efforts are attempting to go one better on nature by generating not plant food but fuels that can be stored for later use. Such projects offer the promise of making new forms of energy while mopping up carbon dioxide, an unwanted greenhouse gas, from the atmosphere. That makes artificial photosynthesis one of the potentially cleanest technologies on the energy horizon. Daniel Nocera and Pamela Silver, from Harvard University, have taken early steps along this road. Their system – the “leaf” is actually a container – uses a catalyst, activated by sunlight, to split water molecules into hydrogen and oxygen molecules. The container is home to hydrogen-eating bacteria, which feast on the newly liberated molecules plus carbon dioxide to churn out liquid fuel.
