Stop Funding Climate Change

Your energy provider matters: One of your biggest household outgoings is likely to be your energy bills. Make sure that money is spent wisely.

It’s easy to fall victim to greenwashing when it comes to your energy supplier. Many of the ‘Big Six’ suppliers offer ‘Green tariffs but are not necessarily generating or delivering renewable energy. They are just offsetting usage using REGO (Renewable Energy Guarantees of Origin) certificates. 

REGOs on the surface, might seem like suppliers are purchasing ‘green’ energy to match your usage but there is a loophole in the system that allows REGO certificates to be traded and sold separately from the energy. So a wind farm owner for example, might sell their green electricity to a supplier but then sell the certificate separately to another energy supplier. This practice can lead to double-counting. 

There are now so many surplus REGOs in the system that an energy supplier can buy enough certificates to supply a typical household with electricity for a whole year, for as little as £1.50 without putting any renewable energy into the grid themselves. So your ‘Green’ Tarriff is not being used to invest in renewable energy generation and might even be funding fossil fuel generation instead.

Ecotricity have produced an easy guide on how green your electricity really is:

So if you’re on one of these ‘Green’ tariffs, check the small print. It might be time to switch. It might even save you money!
