Ecotricity is actually quite competitive if you sign up for their Green Electricity + Car tariff (it includes free electricity for 1000 miles EV use). I would switch except for penalties with current supplier.

Interesting that the 2013 supply mix stats are out, and Ecotricity's proportion of coal generation has risen and thus their CO2/kWh is worse than for 2012. Genuinely surprised at that.

Yes and only sixth lowest in the table of CO2 emissions.
