The two pie charts compare the proportion distribution of energy used in British household and greenhouse gas emissions result from this energy use.
Overall, it is evident that heating and water heating remained dominant components in both charts, although its proportion increased and decreased over time. Meanwhile, other appliances experienced the notable changes, whereas the remaining segments underwent relatively moderate fluctuations.
In British household energy use, heating accounted for 42%, making it by far the most significant segment. This was followed by water heating, which comprised 30%, while other appliances represented a modest share at 15%. Meanwhile, refrigeration and lighting constituted for 7% and 4% respectively. Collectively, these five categories contributed 98% of the total. By contrast, cooling accounted for only 2%, indicating that it made a negligble contribution to the overall distribution.
Turning to greenhouse gas emissions, heating recorded at 15%, despite a significant decrease, whereas water heating rise to 32%. Notably, other appliances experienced the most pronounced shift rising from 15% to 28%. Meanwhile, refrigeration and lighting underwent only a marginal change to 14% and 8%, while cooling rose slightly to 3%, suggesting that the pattern remained broadly similar despite some redistribution among the categories.
