The energy efficiency of US transportation has improved substantially over the past two decades (both absolutely and in comparison to Europe), and US travel volume has grown more slowly than in most of the developed world. However, the United States still consumes more than one-third of the ...
Energy efficiency in Transportation Fig.1 Refrigerated Trailer nits (RTU) Refrigerated Trailer Units are attached to trailers or vans to transport perishable products. Their compressor is powered by small diesel-powered engines and they use R134a refrigerant. We install 8 units in a 2.5 ton RTU, ...
In the last years Energy Efficiency (EE) has become an important issue in the public policy makers' agenda due to ambitious objectives of the European Commission to reduce energy consumption by 20% in 2020. Many countries have adopted state-level EE programs targeted to include Energy Saving (...
We described three uses of energy for which greater efficiency is feasible: transportation, space heating, and air conditioning. Shifts to less energy-intensive transportation modes could substantially reduce energy consumption; the magnitude of such savings would, of course, depend on the extent of ...

In applications where only low-frequency actuation is practical, this pathway may enable additional drag reduction that improves efficiency and/or performance. In particular, for any oscillating surface actuation the power needed to control a spanwise-driven Stokes layer is proportional to ω5/2 30,...
