How schools can cut their power bills, with smart metering and LED lighting

South African schools spend about R5 billion per year on electricity, and reducing these bills with energy efficiency interventions can have a massive impact on school finances - while benefiting the environment.

The electrical engineer Jason Samuels has highlighted some of these energy-efficiency interventions in a PhD about his research in the field.

After graduating with his master's and completing an internship with Eskom, Samuels decided to stick to academia for a little while longer. One of his research supervisors, Professor Thinus Booysen, nudged him to look into energy-efficiency interventions at schools.
