Lighting the Darkness?

The Renewable Energy for Refugees (RE4R) initiative seems to be a very sensible/cost-effective move (https://www.theguardian.com/environment/2022/apr/02/green-energy-refugee-camps-rwanda-solar-panels). More than 40,000 refugees, living long-term in three Rwandan camps, have had their lives transformed by the introduction of solar panels (for lighting) and cleaner-burning stoves (for cooking). The RE4R scheme has reduced crime, illuminated the night-time studies of children and facilitated commerce. Improving the cooking equipment has even reduced rapes and beatings of women, who formerly had to leave the camps to gather wood. Best of all, the equipment costs very little to run and reduces the camp's total 'greenhouse gas' emissions. There is bags of scope for doing something similar in lots of locations. For example, it could benefit people, temporarily displaced by natural disasters like earthquakes, floods and hurricanes. It could even benefit punters, camping at music festivals?
