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 diagram above illustrates how much electric

power

is needed during normal days in

winter

and summer in England.

Overall

, the people's

demand

for electric

power

is much higher during the cold when compared with that in the summertime, with the majority of it being used for heating and household appliances. Looking at the first chart,

it is clear that

during

winter

, the public tends to use more

electricity

with the

demand

ranging from 30000 units to about 50000 at its peak, more than doubling the numbers reported in the summertime, which ranges from 15000 to 20000 electrical units. Demands reach their lowest during the early morning at around 7-9 AM and peak during nighttime at 10-11PM for both seasons.

Moreover

, the

demand

for

power

during

winter

fluctuates a lot,

while

the

demand

in summer tends to be quite stable. The difference in

demand

can be explained by looking at what people are using

electricity

for - with over half of it being used for heating purposes, and

this

correlates with the

demand

graph since during

winter

, people need to stay warm.

Electricity

is

also

used to

power

big household appliances, namely ovens, kettles and washing machines - taking 18% of

electricity

used. Smaller appliances

such

as lighting, TV and radio take up 15%, and so do vacuum cleaners, food mixers and electric tools.
