To save energy at school, I always turn off the lights and air conditioners before leaving the classroom. I also make sure to shut down computers in the IT lab after use. I do these actions every day to develop good habits. These efforts are important because they reduce electricity waste, protect the environment, and help our school save on monthly utility costs for a greener future.
