Should I plug in my electric car?


Both the demand for electricity and the carbon footprint of the electricity produced is low. Demand for electricity is likely to remain low for several hours. Now is a very good time to put your electric car on to charge.

Why are our carbon figures higher than other carbon footprint calculators elsewhere on the web?
Our carbon calculator not only takes into account the generation of the electricity at the power station, but also the carbon footprint for extracting and transporting the raw materials to the power stations and the generation losses between the power stations and the consumer.

The figures also take into account the construction of the power station and the decomissioning at the end of its life.

For this reason, our carbon figures are typically 70-80g/kWh higher than most other calculators on the web.
