Fuel production refers to the process of creating energy sources that can be used for transportation, heating, and electricity generation. This can involve extracting raw materials like crude oil, natural gas, or coal from the earth, which are then refined or processed into usable fuels such as gasoline, diesel, or jet fuel. In addition to fossil fuels, fuel production also includes renewable sources like biofuels, which are made from organic materials, and solar energy, which harnesses sunlight. The goal of fuel production is to meet energy demands while considering environmental impacts and sustainability.
