The first bar chart demonstrates the usage of energy in an average home in Britain, while the second chart illustrates the proportional amounts of greenhouse gas emissions which are produced by this energy use.
Overall, it is obvious that the greatest proportion of energy is allocated to heating, although it is water heating which is the largest contributor of greenhouse gas emissions.
In terms of how energy is divided, it can be said that cooling demands the lowest share of energy at just 2%. Lighting and refrigeration are the next least energy consumers, taking up just 7% and 4% respectively. Water heating requires 30% of energy sources while just over two-fifths of an average household’s energy is used by heating. The remainder is accounted for by other applications.
Turning to the share of greenhouse gas emissions caused by energy sources, cooling contributes to the least share of emissions at just 3%, whereas the opposite is true for the water heating at just below a third. The figures for refrigerating and heating does not show remarkable variations with the former making up 14% and the latter totaling to 15% of greenhouse gas emissions.
