Question

State the difference between Primary Energy (source) and Secondary Energy (source) and two examples of products of fuel as non-energy use.

Answer 1

Primary energy sources are the original sources of energy, while secondary energy sources are derived from primary sources.

Step-by-step explanation:

Primary energy sources are the original sources of energy that are extracted from nature, such as coal, oil, natural gas, wind, sunlight, and uranium. These sources are not directly useful in their natural form and need to be converted into a usable form. Secondary energy sources are derived from primary energy sources and are in a more usable form, such as electricity or hydrogen.

Two examples of products of fuel as non-energy use are:

1. Plastics: Petroleum is used as a raw material in the production of plastics, which have various non-energy applications such as packaging, construction materials, and clothing.
2. Petrochemicals: Petroleum can also be processed to obtain various petrochemicals, which are used in the production of medicines, fertilizers, synthetic fibers, and other non-energy products.
