3.9 million tonnes of CO2
saved of 6.6 million goal
257 days to go
We're on a mission to lower bills and cut carbon emissions. We've set a goal to save 6.6 million tonnes of CO2 by the end of 2019.
Energy is all a bit abstract. It can be hard to understand the impact you have by being with a renewable supplier. To measure this impact, we compare the carbon emissions you have with Bulb to the carbon emissions you'd have if you were with a non-renewable energy supplier.
To make this comparison, we need to know how much energy an average Bulb home uses in a year. In 2018, this was 4,270 kWh of electricity and 12,669 kWh of gas.
Because Bulb provides 100% renewable electricity and 100% carbon neutral gas, an average home with us emits 0.00 kg of CO2 per kWh of electricity and 0.00 kg of CO2 per kWh of gas. Over the whole year, this adds up to zero kg of CO2.
This government report states that UK homes on the average fuel mix emit 0.283 kg of CO2 per kWh of electricity and 0.184kg per kWh of gas. Therefore, over the course of a year, a home using non-renewable energy would emit 1.2 tonnes of CO2 from its electricity usage and 2.3 tonnes of CO2 from its gas usage.
There are 1.1 million homes in the Bulb community and because they're using renewable energy, they're saving an average of 3.5 tonnes of CO2 per home. Across all the Bulb homes, this adds up to a saving of 3.9 million tonnes of CO2 each year. Not bad eh? To put that into context, that's as much carbon saved as taking 2.7 million cars off the road. Which is like removing every car registered in Scotland!
