2007 League Table
WhichGreen exists to help you choose the best green supplier you can, so you have the best chance of actually making a difference with your electricity bill.
At WhichGreen, we believe the best way to measure who's green and who's not is to look at who's building new sources of renewable energy. After all, only by building new capacity can we hope to reduce carbon emissions and fight climate change.
Some energy companies are far bigger than others, so we thought the best way to measure a supplier's green credentials was to look at how much new build they were developing per customer. New generation is based upon the Ofgem commission date of the renewable energy project.
That works out as a simple measure: how many pounds each supplier spent per customer, per year, on building new sources of green energy. In 2007 the average spend per customer of all suppliers was just £8.06.
This is the fourth year the WhichGreen table has been running. And this time we've also produced a new table looking at the average expenditure per customer over the four years WhichGreen has been around.
As ever, we'll leave you to draw your own conclusions.
