Households with high incomes are the main beneficiaries of subsidy programmes supporting the clean energy transition. A team of researchers from the University of Freiburg, Stanford University, Indiana University and the University of Pennsylvania has analysed why this is the case and how energy policy can be made more equitable. The results have now been published in the journal Nature Reviews Clean Technology.
Indoor air quality in modern buildings is increasingly difficult to maintain without high energy costs, and while vertical green walls offer a natural solution, their inconsistent performance and complex maintenance have limited widespread use. VertINGreen, developed by researchers, solves this by using AI, remote sensing, and plant data to both predict how green walls will perform before installation and monitor their health in real time, making them a reliable, efficient, and scalable tool for improving air quality and reducing energy consumption.
