Graph 1 shows that the total consumption peaks between 5 am and 6 am and between 8 pm and 9 pm. This is when people might be using the most electricity at home (making breakfast in the morning and cooking and using technology at night). There’s also a small peak at 3 pm which could be when school children arrive home.
