Fuel mixes and reselling
The values fo kg CO2 per kWh are based on the fuel mix of each supplier. There is potential uncertainty with these figures in that they do not account for the reselling of renewable energy. For example, although Good Energy are undoubtedly more "green" than most other suppliers, it is misleading to assign them the value of 0 kg CO2 per kWh.
