Band 9: The first chart below shows how energy is used in an average British household. The second chart shows the greenhouse gas emissions which result from this energy use. Summarise the information by selecting and reporting the main fea- tures, and make comparisons where relevant.

The pie charts illustrate how energy is used in an average British household and the resulting greenhouse gas emissions.

Overall, heating is the largest consumer of energy, while water heating is the primary contributor to greenhouse gas emissions.

In terms of energy use, heating accounts for the largest portion at 42%, followed by water heating at 30%. Other appliances consume 15%, while lighting and refrigeration account for 4% and 7% respectively. Cooling is the least significant, using only 2% of the total energy. These figures indicate that heating and water heating are the primary areas where energy conservation efforts could be most impactful.

When it comes to greenhouse gas emissions, water heating is the leading contributor at 32%, followed closely by heating at 28%. Other appliances contribute 15%, while refrigeration and lighting account for 14% and 8% respectively. Cooling has the smallest impact, at just 3%. This suggests that focusing on improving the efficiency of water heating systems could significantly reduce overall emissions.
