Energy suppliers can claim to offer environmentally-friendly green tariffs by paying as little as 93p per customer per year to renewable power plants, it has emerged.
Companies which supply electricity to Britons can buy green energy certificates cheaply from wind farms and hydroelectric power stations.
They then have the right to call their tariffs ‘renewable’, even if the power they’re supplying might come from ‘dirty’ fuel such as wood pellets and other non-renewable sources.
