The knowledge of tribology is useful in reducing the unnecessary friction and wear between two rubbings surfaces or tribopair. Using tribology appropriate lubricant and lubrication mechanism can be adopted to minimize the friction and eliminate wear which would reduce the wastage of energy and enhance working life of tribopair.
Please add some more answers
Friction and wear cannot be correlated always, a low friction coefficient of friction (COF) material may give high wear rate than a high COF material. So talking in terms of energy conservation the best part will be minimize the frictional power loss and not to directly concentrate on wear loss.
COF of material can be improved in several ways. Some of them include modifying the surafce, using lubrication, adding fillers etc.
In short where ever we have contact surfaces that are in relative motion there will be friction and there will be power loss due to friction. So a tribologist can look into these areas to improve the COF and to reduce frictional loss there by conserving energy.
Friction is a process that could be considered as the one having double meaning in terms of transmitted power and absorbed energy. Reducing friction and wear is useful for bearings while for braking systems it is more high friction coefficient constancy that matters. In the latter case, therefore, the friction power absorbtion (dissipation) should be as high as possible. The main economic factor in this case will be wear of the material and possible pollution by toxic wear particles
Friction is a direct factor in increasing entropy and contribute to inefficiency due to wear and waste of rubbing parts. So when minimizing friction and wear by enhancing lubrication and optimizing other variables such as speed and temperature you will increase efficiency and thus conserve energy. So understanding Tribology cal factors will contribute to the overall saving of the industry.
Optimization of friction and wear will prevent energy losses and will positively impact the conservation of energy
I just want to recommend the science of Tribology to all people working with machinery or doing anything related to contact mechanic. Understanding Tribology will save lots of mone.
In the last few decades of the twentieth century the field of tribology has undergone a great surge in interest from industry and the scientific community. This is likely due to greater interest in conserving energy and natural resources. By lowering friction we conserve energy, and by lowering wear we increase product life, which conserves raw materials and the energy needed to turn raw materials into useful technology. However, there are many challenges to be overcome in the study of tribology...

"Tribology" means it deals with the friction, wear, and lubrication. whenever two solid surfaces are in sliding contact that moment friction and wear will occur. It arising as a result of change in the contact surface properties. Results, energy losses. One way to reduce these energy losses from the friction is by efficient lubrication. In addition, optimizing the process parameters (Load, sliding velocity, temp, environment and contact surface roughness) is important for controlling the tribological behaviors. Hence, we can conserve energy through effective usage of tribology.
I have so many publications and stated previously that whenever we lessened friction we save energy and when we optimize the parameters that contribute to friction and wear such as temperature and lubricants additives we increase efficiency and thus we conserve energy

Let us discuss this issue from the aspects of machining. If with application of suitable coolant-lubricant, the apparent coefficient of friction at the chip tool interface can be reduced, it would lead to less hinderance to the chip flow. This will provide less thickening of the chip, less deformation, and less cutting forces and associated cutting power. Thus, appropriate tribological condition in machining would result in less energy consumption.
Now instead of application of coolant-lubricant, one can reduce the friction at the chip-tool interface by application of suitable anti-friction coating on the cutting tool. The earliest such coating was TiN. Nowadays, hybrid coatings like TiN + MoS2, TiN + WS2, TiAlN + MoS2/WS2 are being attempted to achieve similar reduction in energy consumption along with enhancement of productivity. Dry turning using such coated tools also saves the environmental cost of manufacturing activity.
Right lubricant can increase engine efficiency and can also lengthen tooling life during milling or turning or ....

"Given how much energy is lost through friction in mechanical components nowadays, tribology is extremely crucial. We must reduce the quantity of lost energy if we want to utilize less of it. In sliding contacts, significant energy is lost owing to friction. Therefore, a greener and more sustainable future depends on developing ways to reduce friction and wear using innovative tribology technology. In the following years, there will likely be an increase in global energy use, placing pressure on the environment and resources. At the same time, friction wastes a significant quantity of energy; for instance, seven quads of energy are lost yearly due to friction in passenger cars worldwide. Further waste is produced when contacting materials wear out since it takes a lot of energy to replace them and wear-induced failures can have high financial, environmental, and safety impacts. In addition, a lot of the difficulties that new energy-efficient technologies, like wind turbines, face are tribological in nature. As a result, tribology is crucial to solving some of the world's most pressing problems about energy efficiency and the effects that energy use has on the economy and society. Wear and friction issues can reduce a machine's efficiency and increase its energy usage. [1] presented their research on the consequences of friction on worldwide energy output, business, and the environment in the transportation and industrial sectors in 2015. They arrived at the result that reducing friction requires 20% of the power generated globally. Therefore, reducing friction and wear can result in significant energy and financial savings, as well as lower CO2 emissions. One of the primary study areas of actual tribology is the development of novel lubricants that can accomplish these objectives without harming the environment."
