The first bar chart illustrates data regarding the division of energy in an average home in Britain. The second bar chart demonstrates the proportional amounts of greenhouse gas emissions which are produced by this energy use.
Overall, the charts show that the greatest proportion of energy in a British household is used by heating, although it is water heating which is the largest contributor of greenhouse gas emissions.
In terms of how energy is divided, cooling demands the lowest energy share of a British home at just 2%. Lighting and refrigeration are the next least energy-hungry categories, taking up 4% and 7% of energy respectively. Water heating requires 30%, while over two fifths of an average household’s energy is used by heating. The remainder is accounted for by other appliances.
Turning to the ordinary British household’s greenhouse gas emissions, cooling again reports the lowest figure, contributing 3%. Lightning is responsible for 8%, and refrigeration and heating make almost identical contributions with 14% and 15% respectively. Almost a third of greenhouse gas emissions are caused by water heating, whereas other appliances make up the remaining 28%.
