It is universally well-known that the tip of the present and the start of the following century might be characterised by way of a thorough swap within the latest developments within the monetary improvement of all nations and a transition to new ideas of monetary administration at the foundation of a source and effort conservation coverage. therefore there's an pressing necessity to check tools, technical aids and fiscal effects of this modification, and especially, to figure out the potential quantities of power assets that may be conserved (energy "reserves") in numerous spheres of the nationwide economic system. An elevated curiosity in the direction of power conservation in undefined, one of many greatest strength shoppers, is sort of common and is manifested via the big num­ ber of courses in this subject. however the majority of guides are dedicated to the answer of narrowly outlined difficulties, choice of power reserves in particular methods and crops, potency estimation of person strength conserva­ tion measures, and so forth. in spite of the fact that, it will be significant to strengthen a basic methodological method of the answer of such difficulties and create a systematic and methodical base for knowing an strength conservation coverage. Such an attempt is made during this e-book, that is curious about equipment for learning power use potency in technological techniques and estimation of the theoretical and real strength reserves in a given strategy, expertise, or commercial area at the foundation in their whole power balances.

It can show how to decrease the volume of energy resources consumed or to change their composition. At present the exergy method is widely used. Among the more important publications discussing the subject are [31, 80, 81, 112-114, 174-176, 179, 184186]. Jeschar and co-authors [31, 80, 81] consider the problem of drawing up an analyzing the energy balance for a ferrous metallurgy plant on the basis of exergy as heat, heat flows and chemical reactions. The concept of exergy makes the energy balance calculated by the general method more exact and clear, as is seen from the comparison made by Jeschar.

Determination of potential and reserves of energy conserved due to process improvement. 4 Theoretical Potential and Energy Reserves 33 to the energy consumption level in the idealized or ideal analog (E1)id. In other words, the energy saving potential is the maximum possible difference between the achived (EI)~ and theoretical energy (exergy) consumption. Similarly to the actual energy consumption, which decreases over time due to process optimization towards the energy consumption value of the idealized or ideal analog, the energy saving potential asymptotically approaches zero with increasing time.

Development of standards on the specific energy consumption per unit of product or labor is a necessary base for calculating the demands of a process, a workshop, or a plant for energy carriers. These data, in tum, are the input data in budgeting the demand for energy resources of economic sectors, which finally, allows a nation's energy balance to be derived. Complete energy balance is the most appropriate means of standardization of the consumption of different energy resources. It can be the basis for determining the specific consumption of conventional energy resources with account of the chemical energy (exergy) of raw and auxiliary materials entering the process.
