Greenwashing energy

REGOs, GoOs and fake green tariffs. Everything you need to know about how energy suppliers go about greenwashing.

As the world wakes up to the urgency of climate change, more and more people want to do their bit to help fight it. And one of the easiest ways to do so is by switching to an energy company that supplies 100% renewable electricity. 

Or at least it should be. Unfortunately, greenwashing and the broken regulation around green tariffs is making it harder 

Why choose a green tariff?

Our research has shown that 65% of people would switch to a green tariff if it meant that it helped support the transition to a clean energy system.  

More than half of the energy tariffs available today are being marketed as ‘green’. But in the vast majority of cases, the suppliers offering these tariffs are buying dirty power from the wholesale market, and labelling it green through a regulatory loophole. Meaning they are not doing what customers want them to do — supporting the growth of renewables. 

How do fake green energy tariffs work?  

Every electricity supplier must match the amount its customers use with power sourced from somewhere. Suppliers offering green tariffs are supposed to source this power from renewable generators.  

However, instead of most suppliers offering ‘green tariffs’ simply buy power on the wholesale market, which is a mix of all sources including fossil fuels and nuclear. They then separately acquire certificates to label this brown power ‘green’. The certificates are either UK Renewable Energy Guarantees of Origin (REGOs) or European Guarantees of Origin (GoOs).

It is a complex topic, so here we have pulled together all the resources you might need to get to grips with it.
