Should I plug in my electric car?


Demand for electricity is at acceptable levels and the carbon footprint is below average. However, 78% of the electricity supply is currently being generated from fossil fuels.

Electricity demand is likely to gradually increase over the next few hours, and the carbon footprint is likely to increase with it. If you need to charge up your electric car in the next few hours, do it now, not later. Consider a SHORT CHARGE if this is feasible.

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.
