This review article discusses the impact of tribology on global energy consumption, costs, and emissions. It highlights that approximately 23% of the world's total energy consumption is attributed to tribological contacts, with 20% used to overcome friction and 3% for remanufacturing worn parts. By implementing new surface, material, and lubrication technologies, energy losses due to friction and wear could be reduced by 40% in the long term and 18% in the short term. These savings would amount to 1.4% of the GDP annually and 8.7% of total energy consumption in the long term. The largest short-term energy savings are expected in transportation (25%) and power generation (20%), while potential savings in manufacturing and residential sectors are estimated at around 10%. In the long term, savings are projected to be 55%, 40%, 25%, and 20%, respectively. The implementation of advanced tribological technologies could reduce global CO₂ emissions by up to 1,460 MtCO₂ and result in 450,000 million Euros in cost savings in the short term. In the long term, the reduction could be 3,140 MtCO₂ and the cost savings 970,000 million Euros. The study also emphasizes the importance of tribology in reducing energy consumption, economic losses, and emissions, particularly in the transportation, manufacturing, power generation, and residential sectors. The article discusses various technologies and methods for reducing friction and wear, including lubricants, materials, component design, and new methodologies such as nanotechnology and biomimetics. The findings indicate that tribology has a significant impact on global energy consumption, costs, and emissions, and that further research and implementation of tribological solutions are essential for sustainable development.This review article discusses the impact of tribology on global energy consumption, costs, and emissions.
