Band 8+: The bar chart shows the relative electricity consumption and cost per year of various household devices. Write a 150-word report for a university lecturer explaining the data and making comparisons where relevant.

The bar chart presents data on the annual electricity consumption and cost of various household appliances.

Overall, the electric blanket has the lowest electricity consumption and cost, while the spa pump and heater have the highest. Additionally, kitchen and bathroom devices generally have higher consumption and cost compared to other household devices.

In detail, appliances such as the electric blanket, microwave oven, television, and dehumidifier consume less than 500 kilowatt-hours (kWh) per year, each costing less than 42 dollars annually. The home computer falls slightly above this cost. However, kitchen and bathroom appliances, including the dishwasher, electric cooking, freezer, water bed heater, clothes dryer, washing machine, and refrigerator, cost nearly twice as much as the electric blanket. Particularly, the refrigerator’s consumption exceeds 1000 kWh, costing more than 83 dollars yearly.

Notably, the spa pump and heater have the highest annual expenditure, exceeding 2000 kWh, costing nearly 208 dollars annually. Following closely is the pool pump, costing about 125 dollars yearly. The combined cost of the pump and spa exceeds 4 times that of the electric blanket.
