Energy and Sustainability Research

Energy efficiency and sustainability are fundamentally rooted by tribology. Sustainability requires that we reduce consumption/demand while replacing non-sustainable energy sources with sustainable sources. Friction and wear drive the energy demand in the U.S.; friction in passenger vehicles alone, for example, accounts for about 8%. Elevated operating temperatures and thermally-tolerant materials can increase carnot efficiency, while improved tribological materials and lubricants can reduce losses from friction and wear. In the wind industy, unpredictable drivetrain bearing failures dramatically increase the cost of wind power; durability is the key barrier to 20% wind energy by 2030.
