Case studies electric utility

The major cause for the 38% increase in C02 was a more than doubling of the coal use in electric utilities and a near doubling of coal use in industrial use. The energy efficiency path still increased C02 production to 1.5 billion metric tons per year. The high-efficiency case does use less coal. Other energy studies predict a decline in energy-growth rates and a decline instead of an increase in C02 emissions.

This case study shows how shared resources can simultaneously improve efficiency and reduce vulnerabiUty through resource reuse. Heller et al. (1999) discuss the coucept of shared resources as a means of achieving regional eco-efficiency. In this context, information system boundaries are extended to coordinate the shared production, consumption, treatment, or reuse of electricity, water, and wastewater resources among regional utilities and manufacturing facilities. 

Self or mutual It is worth mentioning that the model of a pole made of only a type of charge (all positive or all negative) does not utilize the internal capacitance (self-capacitance) but the mutual capacitance, which expresses the influence of another (or several) pole. (See case study D4 Coulomb s Law in Chapter 7.) The reason is that, in electrostatics, an electric charge does not create its own potential on the location of the charge itself but creates a potential at distance, through the electric displacement and the electric field. 

Ideal case. The thermoelectric junction constitutes the basic system in the domain of thermoelectricity. It is not utilized alone as in the case study treated here but with another junction for making up a thermocouple, each junction being raised to a different temperature. The reason is quite logical In order to electrically connect the two materials of a junction with the exterior and make an electric circuit, it is compulsory to use somewhere at least another junction, if only for closing the circuit with the same materials used in the junction. 

Dynamic case. It can be remarked that no utilization of electric current and of entropic flow (heat flux ) is made in this model, although devoted to dipoles that are endowed with the possibility of using them. This is because of the absence of an external circuit for allowing these flows to circulate. It does not mean that it is impossible to utilize a junction in an electric and thermal circuit and to make these flows cross it, while keeping the same model of coupling (see case studies J9 Seebeck Effect and JIO Peltier Effect ). 

The most important lesson learned from these case studies is that reliability and safety are of paramount importance for HEB and EBs utilizing LIBs for energy storage in their hybrid drive for electric propulsion. 

In reality, however, CWS represents a family of fuels. They are variable based upon the sources of fine coal, the size fractions of the fine coal, the extent of coal processing, the density of the slurry, and related factors. If produced from coal pond fines these fuels can be high in ash and high in certain trace metals. In order to consider these opportunity fuels, this chapter first considers the basic published properties and then examines case studies of CWS production and utilization. Following the consideration of CWS, the chapter discusses analogous fuels and then the direct use of waste coal products in electricity generating stations.
