Power companies pay as little as 93 pence per customer to have the right to claim dirty energy prices are in fact green.
There are 111 energy tariffs now classified as renewable out of 282 in the market, or 39% of the total, and the cost of these deals is falling. But a Sunday Times investigation revealed enormous confusion over what renewables really mean, as suppliers can “green” fossil fuel energy by purchasing certificates.
Whatever the tariff applied, each household in the country receives exactly the same energy from the national grid. So even if you signed up for a 100% green energy supplier, you get 40.6% gas, 2.1% coal, and 17.3%.
