U.S. oil imports have dropped from a peak of 8.9 mbd (million barrels per day) in 1977 (6.2 mbd from OPEC countries) to 5 mbd in 1982. Simultaneously, U. S. demand for oil has dropped from 18.4 mbd to 16 mbd, and our dependency on imports has dropped from 43 percent to 37 percent. Unfortunately,...

Most energy conservation analyses assume various future paths for energy prices and other parameters and then proceed to calculate the optimal value of conservation investment under the specified assumptions. Sensitivity analysis is used to examine the amount which the calculations change as...

Population growth, continuing suburbanization, and higher labor-force-participation rates, combined with a virtual halt in new freeway construction, have led to rapid increases in traffic congestion in the U.S. This congestion is costly, for example, the cost of highway congestion in the Lose...

It is unlikely that roadway construction or vehicle automation will be able to alleviate most major urban congestion in the near future (5-15 years). What else can be done to reasonably reduce congestion? Several approaches to reducing congestion by capacity allocation are reviewed:...

Engineering models of the physical processes of energy use in individual houses are quite complex. We investigate simple statistical models of summer electricity use and compare them to engineering models. Our data include interviews, energy audits, and utility billings for a random sample of...

Total electricity use and cooling loads for a three month cooling season (July–September, 1980) in single-family detached houses in Davis, California, are estimated and compared with measured data. Total electricity use is estimated by predicting cooling loads and appliance electricity use...
