The debate over the availability of conventional natural gas has been nearly as strong as that for conventional oil. In … availability of natural gas in the region. This is done by estimating a cumulative availability curve showing natural gas endowment … versus production costs. The findings indicate that natural gas in Europe is more available and economic than often assumed …

We develop a theoretical model of long-run investment decisions on capacity in the context of a liberalized electricity … the level of capacity that maximizes social welfare, and compare it to a decentralized outcome. We show that in the … absence of any regulation, private investment decisions on capacity unambiguously lead to a socially sub-optimal outcome, and …

The present study examined unit roots, causality, cointegration, and efficiency of the natural gas market using the … Northwest US natural gas markets as a case study. The results indicate that the natural gas market prices are stationary after … the first differencing, and that spot and futures natural gas prices move in a similar direction. Spot prices tend to …

An exergy-based thermoeconomic optimization application is applied to a subcooled and superheated vapor compression refrigeration system. The advantage of using the exergy method of thermoeconomic optimization is that various elements of the system—i.e., condenser, evaporator, subcooling and...

We show that thermoelectrics can generate power from environments experiencing temporal temperature fluctuations; this source of power is useful for low-power devices in remote locations. We design and characterize devices that employ a thermoelectric module sandwiched between two heat...

A new method has been developed to determine the area of waste heat recovery heat exchangers considering the lowest saving-investment ratio corresponding to the area at the tag end of the heat exchanger. Applying this method to any existing heat exchanger, the saving-investment ratio performance...
