E10
In short
E10 is a type of petrol in the United Kingdom that contains up to 10 per cent bioethanol.
In plain words
It is a blend of regular fossil fuel and plant-based alcohol. This mixture is designed to reduce the amount of carbon released when driving.
A simple example
When you visit a petrol station, you might see a pump labelled E10 instead of standard unleaded. This fuel is often cheaper than pure petrol.
Why it matters
Using biofuels helps lower the carbon footprint of transport. It is a key part of moving towards more sustainable energy sources.
Easy to mix up
Do not confuse it with E85, which contains much higher levels of ethanol and requires a special engine.
