Ugly side of crude oil
Oil spills during transportation
Releases carbon dioxide when burnt
Drilling for oil have become more difficult and expensive as we are drilling deeper than 20,000 metres to find new reserves.
Non-renewable
Contains sulfur compound, contributing to acid rain
Average age of worker in the oil industry:50 years old
Much of our remaining crude oil reserves are located in politically unstable countries, such as the middle east countries, making it difficult to obtain them.
Transportation of biodiesel is costly and difficult
clean burning, so lesser pollutants are produced
Cons of biodiesel
can be used directly without refining
Why choose biodiesel?
Additional land is required to produce more plants, in order to meet the demand
Increases nitrous oxide emission
made from 100% renewable resources, so it is sustainable
biodegradable and non-toxic
More expensive than petroleum
