The graph below shows the demand for electricity in England during typical days in winter and summer. The pie chart shows how electricity is used in an average English home.

The line graph illustrates the number of units of

electricity

consumed by the British on daily basis during

summer

and

winter

,

while

the pie chart gives information about the domestic use of

electricity

in four different areas in proportions. Looking from an

overall

perspective it is readily apparent that usage of

electricity

is much higher in

Winter

than in

Summer

and towards ,nighttime it shows a slight increase in both seasons.Heating rooms and water are the main purposes of domestic power supply. In

Winter

,consumption is between 30000-50000 units of

electricity

while

it is around 10000-20000 in

Summer

.Early morning hours are considered off-peak in both seasons but during

winter

rise to 40000 units around 3 am.During the late hours( around 20-23 ) usage increases and reaches a peak of just below 50000 and 20000 in

winter

and

summer

respectively. More than half of the

electricity

is channelled to heating purposes (52.5%).Meanwhile , lighting,tv,radio group and vacuum cleaners,food mixers, and electric tools category share an equal proportion of the

electricity

supply, 15% each.
