Ecotricity more eco than previously reported

It seems that the robot spiders who run the internet have informed Ecotricity about my deliberations: I've received an email from Madeline Carroll of Ecotricity who mentions that the details about the company that I read on the two comparison sites I used (energyhelpline.com and uSwitch.com) are rather out of date. Whereas they claimed the Ecotricity electricity is "10%+ green", the actual figure for 2006/2007 is 30%.

From my point of view this means that Ecotricity's tariff is even more clearly the greenest of those I've encountered, if not the cheapest. But even the cost is pretty vague—energyhelpline suggested that it would cost me £19 a year more than I was currently paying, yet uSwitch insisted I would actually save £19 a year on that tariff. I haven't cross-referenced this any further with other sites, but I guess the message is that this is what you should do before making a change.

Last thing I heard Ecotricity were off on the warpath to harry the comparison sites into updating their details. In the meantime I gather that Ecotricity's Dale Vince has launched his own blog. You can find it at http://zerocarbonista.com/.
