Milling is performed through a sequence of breaking, grinding, and separating operations. Quality of the wheat determines the type(s) of flour to be produced. Different types of flour produced at a mill can be combined to create further variations. Wholemeal flour contains all parts of the kernel, including the bran, germ, and endosperm.

Energy consumption fell in most countries, except in China, the largest energy consumer (24% of the global energy consumption in 2020) which rapidly recovered from the COVID-19 crisis. China's energy consumption rose by 2.2%, a much slower pace than in previous years (+4%/year over the 2008-2018 period and +3.4% in 2019).

Energy. The mining industry consumed an estimated 551 trillion British thermal units (Btu) in 2002. 3 Major energy sources include fuel oil, electricity (purchased and produced on-site), coal, and natural gas. The energy-intensive nature of mining is evident by the recovery ratio of the various materials being mined.
