Solar energy application is a good alternative to replace primary energy source especially for large-scale installations. Heat pumps are also effective means to reduce primary energy consumption. This paper describes a case study with a new design of solar assisted heat pump (SAHP) for indoor...

The potential economic damages from oil supply disruptions could be suppressed by emergency preparedness and response measures. As two of the most feasible response measures, oil import tariff and strategic petroleum reserve (SPR) could alleviate short-run oil supply and demand imbalance...

Biodiesel continues to be an alternative fuel of interest for use in diesel engines. Although biodiesel’s properties are similar to petroleum diesel’s, certain differences create possibilities for parameters, such as efficiency, to be different. The objective of the study is to identify the...
