Household Energy Consumption

The table below gives you an idea of 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 it could save you £12 per year in electricity costs if used instead of a standard 100W bulb.

The energy saving could therefore pay for the initial cost of replacing the bulb within the first year, as well as reducing your carbon footprint. To buy these at low cost please click here
