This is the relative percentage of the capitation grant that a school pays in electricity (and other energy) since 2007. If we were to say that 10% of a school’s capitation grant was spent on electricity in 2007, relatively depending on the grant each year, this is how much it cost. This graph alone should tell you everything you need to know about why schools are struggling financially. https://pod.fo/e/2c0e58 (Link in bio)
