Electric car emits more CO2 than diesel, but cost less than a third to run!

Buying an electric car could be seen as ultimate green statement, especially when the showroom is filled with zero emissions brochures extolling the eco credentials of these cars. Okay, there are no tail pipe emissions as you travel, which is a great thing if you live and travel in an urban environment, however, the green credentials – in terms of CO2 emissions – become a little hazy when you factor in the CO2 generated in electricity generation.

Electric car emits more CO2 than diesel

We’ve recently added electric car running cost to the Sust-it site, our calculations include CO2 generated from electricity generation.  This has certainly thrown-up some interesting emission figures for an electric cars, charged by standard mains electricity.  For instance, the Nissan Leaf the first mass-produced electric car emits more CO2, than the most efficient diesels available today, according to Vehicle Certification Agency energy label testing data.

If you are considering purchasing an electric car on eco grounds, it’s worth remembering that you will need to buy or generate your electricity from renewable sources for the CO2 emissions to be substantially lower than the most efficient diesels!

    If you are going to look at the whole end to end chain of electricity production costs, then you also need to look at the end to end cost of producing petrol and diesel. This will include crude oil production, transport, refinement, transport etc etc. For every ltr of petrol refined, it takes 1 kw of electricity !!!

    Also whereas as all fossil fuel cars have to be fuelled by oil company products, EV’s can be fuelled from solar roof panels, wind turbines etc at your own property.

    Electric cars emit 50% less greenhouse gas than diesel, study finds.

    Electric cars emit significantly less greenhouse gases over their lifetimes than diesel engines even when they are powered by the most carbon intensive energy, a new report has found.

    What a load of tosh. With no reference to any source for this urban myth whatsoever.

    The process of refining ONE liter of petrol / diesel uses roughly 1 kWh of electricity alone. And that electricity is bound to not be from slightly more expensive renewable sources, like the electricity used by most electric cars.
