A Renewable Energy Guarantees Origin or REGO, certificate was developed to meet an EU requirement for all member states to record an report the proportion of electricity consumption from renewable sources. One REGO issued per MWh of electricity generated. However these certificates can be purchased from generators for as little as 50p, enabling suppliers to create ‘green’ tariffs and charge a lot more for the energy, despite doing nothing significant to generate green energy or reduce carbon emissions. Also REGOs from already subsidised generation are not considered truly green by many because they do not incentivise new renewable developments
