Fuel manufacturing involves the production of various types of fuels used for energy. This process includes refining crude oil into gasoline, diesel, and jet fuel, as well as producing biofuels from organic materials. The goal is to create fuels that can power vehicles, machinery, and generate electricity. In addition to fossil fuels, manufacturers also focus on renewable energy sources. This includes the production of ethanol from crops and biodiesel from vegetable oils. These alternative fuels aim to reduce greenhouse gas emissions and reliance on non-renewable resources, contributing to a more sustainable energy future.
