The industrial sector plays a pivotal role in global energy consumption, accounting for a substantial 33% of the world's electricity usage. In the United States alone, manufacturing dominates this consumption, utilizing 77% of industrial electricity, with mining, construction, and agriculture following suit at 12%, 7%, and 5% respectively.
Among manufacturing industries, high energy consumption is notable, with chemicals leading at 37%, followed by petroleum and coal products at 22%, and paper and primary metals at 11% and 8% respectively. The collective energy usage of these top six industries totaled 16.9 quadrillion BTU in 2018, showcasing significant demand.
1. Chemical Industry: Despite its diversity, a select few products such as ammonia, chlorine, and petrochemical intermediates contribute significantly to energy consumption.
2. Petroleum and Coal Industry: From crude transformation to product refinement, this sector involves complex processes like cracking and distillation, contributing substantially to energy consumption.
3. Paper Industry: Energy-intensive processes in pulping and papermaking are essential for transforming wood fibers into paper products.
4. Primary Metals Industry: Iron and steel mills, aluminum production, and foundries drive energy consumption through various manufacturing processes.
