Each year, students from the module ‘Energy, Environment and Resources in Developing Countries’ are asked to write a short blog on a topic related to the topic of the module. Once again, we were delighted by the quality of the blogs and the range of topics that students address – everything from the role of hydrogen in the Beijing 2022 Winter Olympics to Madagascar’s clean cooking challenge. Here we present the three blogs that received the highest marks. Our congratulations to all the students and particularly to Esther, Nadhira and Matthew!"
