This article talks about making private schools in Egypt more energy efficient by changing the way they use energy. Right now, these schools use a lot of electricity for air conditioners without thinking about better ways to keep students cool. The researchers want to show how to upgrade these schools so they need less energy. By improving the buildings and using solar panels, the researchers found that energy use can go down by 33% and the schools can even make their own energy. This helps the environment by reducing carbon dioxide emissions. Essentially, by fixing up school buildings with better technology, they can become more energy efficient and produce their own power.
