The graph illustrates the demand for electricity in England on average winter and summer days. Meanwhile, the pie chart represents the purpose for which electricity is commonly used.
Overall, it can be seen in the graph that the demand for electricity is high during the winters as compared to summers. Whereas, the pie chart shows that more than half of the electricity is mainly used for heating rooms and water.
In the graph, it can be observed that there is a high demand for electricity during winters (30,000-45,000 units). During the daytime (9:00 hours), the units incline at a steady pace from 31,000 units to the highest at 45,000 units by nighttime(23:00 hours). However, during the summer days, the demand for electricity stays between 10,000 units and 20,000 units. There is a slight rise in the demand for electricity from 9:00 hours (at 13,000 units). The peak demand can be noticed at around 13:30 hours, which is around 21,000 units. Later during the day it fluctuates and swells up by 23:00 hours.
Meanwhile, due to utilization, more than half of electricity goes for heating rooms and water (52%). Whereas, other appliances usage is low in comparison. It is close to 48%, which is used for ovens, kettles, lighting, TVs, vacuum cleaners, and other such appliances.
To conclude, usage and demand for electricity differ and fluctuate as per the seasons.
