Last week, electricity used at night decreased by 5.7% compared to the average over the last year. Keep this up and the school will save £150 over the next year.
Bad News! Your school's electricity use in the Spring half term 2025 holidays has increased by 24% compared to Spring half term 2024. Between Saturday 15 Feb 2025 and Sunday 23 Feb 2025 you used 250 kWh at a cost of £75. This is an increase of 49 kWh compared to the same period in the holidays last year and released an extra 1.3 kg CO2.
There is a large variation in seasonal overnight electricity usage from 2 kW in the winter to 0.69 kW in the summer. This suggests electric heating is left running overnight during the winter or the school has inefficient security or flood lights. Change electric heater settings and improve lighting efficiency to save £440 annually.
Over the last year 37% of electricity was used when the school was closed, costing £2,700. This is good compared to many schools, but could you reduce out-of-hours electricity use even more?
