Many electricity supply companies have introduced green schemes and tariffs of some sort. See the section on greener electricity for background information.
The following are some of the major schemes that Green Choices has come across. The information is taken from the companies’ own websites and the tariffs they offer and the prices they charge are subject to change. Green Choices cannot vouch for the accuracy of the information, or the availability of any particular tariff.
Green Choices does not have the resources to maintain an up-to-date list. However, Sust-it has ranks UK energy suppliers by their fuel mix, form most renewable electricity generation or by CO2 emissions.
