What is 100% renewable electricity?
You’ll hear this phrase from your energy supplier, but honestly, not many people know what it is exactly. More often than not, people choose to ignore it (because of all the jargon everyone uses). Simply put, it means all of the electricity we provide you with comes from 100% renewable sources like wind, solar and hydro.
To do this we have supply agreements with independent UK wind generators and purchase renewable electricity certificates and Renewable Energy Guarantees of Origin (or REGOs). The electricity supplied to homes and businesses ultimately comes from the National Grid.
So what are REGOs?
Renewable Energy Guarantees of Origin are proof an energy supplier has bought a specific amount of energy from renewable sources.
We use REGOs to ensure the electricity we supply is backed by renewable sources. It’s as simple as that.
Why is it important?
We want to help our beautiful planet become a better place. A planet where everyone is working towards a zero carbon life. This is an easy and efficient way for everyone to get involved.
If all of us decided to change to 100% renewable electricity, it could literally save us thousands of tonnes of carbon emissions per year.
To be more specific, it can save an average household 1.1 tonnes of CO2 a year**.

**We have worked this out by using Ofgem’s average yearly electricity consumption of a medium house (2900kWh) multiplied by the weighted average carbon intensity of the current BEIS published UK residual fuel mix, covering the period between April 2020 - March 2021, published in August 2021 (2900kWh x 0.392334kg CO2/kWh = 1138kg CO2). To calculate the carbon avoided, we then compare this to the 0kg CO2/kWh Carbon intensity for residential customers in E.ON Next (Sainsbury’s Energy is a trading name used under licence by E.ON Next Energy Limited.) who receive electricity backed by REGOs. (2900kWh x 0kg CO2/kWh = 0kg CO2).
