Fuel oil and bitumen is 38% in demand

Petrol and Naptha is 27% in demand
Diesel is 23% in demand.
A question asks: Why are these fractions in demand?
I am not sure how to answer this questions and please advise me to how to answer this question.
Thanks in advance

Fuel oil is used for heating homes and industrial plants. Bitumen is another word for asphalt and it is used in a variety of ways. Petrol and diesel are used for automotive and other engines. Naphtha is used a a solvent. I suppose the law of supply and demand is what creates the demand. There is a demand because they are useful for a number of purposes. You can edit this to fit the question.

Thank you very much, this information has helped to answer my question.

To answer why these fractions are in demand, we need to understand their uses and relevance in various industries. Here's how you can approach answering the question:

1. Define each fraction: Start by explaining what each fraction is and its different properties. For example:
- Fuel oil and bitumen: Fuel oil typically refers to a blend of liquid hydrocarbons derived from crude oil. Bitumen is a thick, sticky form of petroleum that is mainly used in road construction and waterproofing.
- Petrol and Naptha: Petrol, also known as gasoline, is a refined product used as fuel for internal combustion engines in automobiles. Naptha is a light distillate obtained during petroleum refining and has various applications in industries like petrochemicals and solvents.
- Diesel: Diesel fuel is a heavier, more viscous product compared to gasoline and is commonly used in diesel engines for transportation, power generation, and industrial applications.

2. Highlight their demand drivers: Elaborate on the factors that contribute to the high demand for these fractions. Some key points to consider are:
- Energy needs: These fractions serve as vital sources of energy for various sectors, such as transportation, manufacturing, and electricity generation.
- Industry-specific requirements: Different industries have specific requirements for fuel or raw materials, and these fractions may be ideally suited to meet those needs.
- Price and availability: The cost-effectiveness and availability of these fractions also play a crucial role in driving demand.
- Infrastructure dependency: The demand for bitumen and fuel oils can be influenced by infrastructure development, particularly in the construction industry.

3. Discuss environmental considerations: Mention the impact of these fractions on the environment, as it is a significant concern for many consumers and policymakers. For instance, while diesel fuel is known for its higher emissions compared to gasoline, advancements in refining techniques and the introduction of cleaner fuel standards have reduced environmental impact.

4. Provide examples: To support your explanation, give specific examples of real-world applications and industries that rely heavily on these fractions. This can include transportation, construction, petrochemical manufacturing, and power generation industries.

Remember to present your answer in a clear and concise manner, and use reliable sources or industry data to support your points.
