Bio-diesel: green fuel we can use today
Take some rapeseed, sunflower or soya oil, or recycle some used cooking oil, refine, mix with a diesel engine and voila! A non-toxic, biodegradable green fuel that can be used in any diesel engine.
Although the plant-based fuel is not pollution-free, it is significantly cleaner than its petro equivalent and causes just half the damage to the climate. Its widely used in the US, Germany and France, so why isn't the UK enjoying the environmental, economic and health benefits too?
