It's 2016. Of course we're going to be renewable. That's why 100% of our electricity comes from renewable sources. Green gas is a little more tricky, since almost all of the UK's gas is natural gas from the North Sea and other non renewable sources. 10% of our gas comes from renewable carbon neutral sources. This is 100 times higher than the national average of 0.1%.
We've partnered with Icknield Farm who take slurry from piggeries in Oxfordshire and then anaerobically digest it to create biomethane. Biomethane is gas that naturally occurs through decomposition of organic matter. When bacteria break down plant material, sewage and organic waste this releases methane. This can then be captured, refined and fed into the gas grid. It's carbon neutral, meaning there is no net release of carbon dioxide into the atmosphere. In other words, it doesn't contribute to an increase in global warming. You can read more about the environmental benefits on biomethane.org.uk.
All of the biomethane that we source is certified by the Green Gas Certification Scheme. This ensures our green gas is tracked from production to end use, and is indeed renewable. All of this gas comes with a Renewable Gas Guarantee of Origin certificate which lets us prove our fuel mix.
As you might expect, we're planning to grow the proportion of our gas that comes from clean and renewable sources. We'll continue working with more green gas producers to support this exciting new technology.
