The line graph illustrates the consumption by four sectors during the period from 2005 to 2020.
Overall, it is obvious that the amount of electricity consumed by sector A and D witnessed a steady increase, whereas the figure by sector B experienced a gradual decline over the period shown. Besides, that of sector C showed a steady fluctuation throughout the period.
In 2005, the consumption of electricity by sector B was the largest, standing at 60 terawatt hours before seeing a steady decrease from 60 to 30 terawatt hours throughout the period. Meanwhile, both sectors A and D consumed electricity at around 30 and 10 terawatt hours respectively in 2005. However, from 2005 to 2008, sector D remained relatively stable, staying at 10 terawatt hours before witnessing a slight rise, reaching over 30 terawatt hours in 2020.
In contrast, the amount of electricity consumed by sector A climbed gradually, increasing from 30 to over 50 terawatt hours between 2005 and 2020. Additionally, there was a steady fluctuation in the figure by sector C, fluctuating in the range from 20 to 30 terawatt hours over the period.
