Household Energy Consumption

Helping you to understand where energy is used

The table below shows which appliances in your household are contributing the most to your carbon footprint

We have highlighted the low energy light bulb in red to show you that changing just one will save you about £12 per year in electricity costs compared to using a standard 100W bulb.

The energy saving will easily pay for the initial cost of replacing the bulb, well within the first year, as well as reducing your carbon footprint.
