This document summarizes the electricity consumption patterns at a secondary school and vocational college over various time periods. It shows that consumption begins to increase in the mornings when classes start and is highest during weekdays. Consumption drops on Fridays and is lowest on weekends and during summer holidays when fewer people are at the school. Charts of daily, monthly, and weekly consumption patterns demonstrate that off-hours and vacation usage remains too high. The document concludes by suggesting energy efficiency strategies like using fewer lights, controlling technology usage, and installing solar cells.

12. THINK FOR THE FUTURE:
FUTURE
• ECO-GUARD
• One bulb instead of two (outside lights)
• Fewer spotlights at night
• Greater control of electric gadgets:
switching off our computers
(not stand by)
• Solar cells

13. That’s
all
folks!
