ABSTRACT 
 
 A method is developed for determination of the total energy 
 (direct plus indirect) and the lahor requirements to produce a unit of 
 output from an industrial plant or facility. The total energy and labor 
 requirements are determined by accounting for all energy and labor as the 
 product or raw materials flow from the mine or other natural resource 
 through all production and manufactures to a given production status. 
 In this way, each manufacturing step is accounted for in its contribution 
 to the total energy to produce a unit of product. The work requires an 
 examination and evaluation of the input-output structure of the plant 
 or facility in question, usually from the viewpoint of cost accounting 
 data sources. To illustrate the method, several specific plants are 
 studied.

INTRODUCTION 
 
 A complete energy "balance of a plant or manufacturing facility in- 
 volves both direct and indirect energy flovs. For years, the importance 
 of indirect energy has been largely neglected or avoided and attention 
 has been focused on only direct energy balances and thus the measures 
 that have been taken to conserve energy involved largely direct energy 
 concepts. This led, for example, to turning down thermostats, better 
 insulating, closing doors, and similar measures. Previous research done 
 at the Center for Advanced Computation (CAC), University of Illinois 
 at Urban a- Champaign [1,2] indicates that the percentage of indirect 
 energy in the total energy required to produce a product is often con- 
 siderably greater than that of direct energy for many industry types . 
 Again, for many industries the portion of indirect energy is comparable 
 to or greater than direct energy. The consideration of conserving total 
 energy, of course, adds a new dimension to energy conservation concepts 
 for several reasons. 
 
 A total energy balance for a given plant stems from the idea of 
 "energy intensity". Specifically, it is now known [1,2] that the 
 majority of industrial commodities produced in the United States and 
 similar economic societies require typically from 50% up to 90$ of the 
 energy in the indirect form. Consequently, energy conservation efforts 
 related to reducing indirect energy hold considerably greater potential 
 for a larger net savings in energy per unit of final output made available 
 to the public sector. A second and equally important reason to concen- 
 trate on reducing total energy per unit of final output is that minimi- 
 zation of direct energy by a single plant, for example, involved in only 
 
 -1- 
 
one of the many steps required to produce a unit of final product does not 
 necessarily lover the total energy to produce the unit of final output. 
 In fact, the converse is often times true in that a direct energy minimi- 
 zation at a given step of manufacture can result in an increase in the 
 total energy content in the final output. 
 
 This point may "be illustrated by any of many examples , and all of 
 them fall under the description of what is called exporting one's (direct) 
 energy requirements. In the manufacture of automobiles, consider a manu- 
 facture X who not only assembles the final components comprising the fin- 
 ished automobile, hut also performs many preliminary manufacturing steps 
 including the process of steel making. If one considers merely the 
 energy intensity of X (direct energy) as the energy added during the 
 final manufacturing step in X's factory per unit produced, then X can re- 
 duce his direct energy requirements merely be electing to purchase steel 
 rather than manufacture it. Thus, X has made himself look better instant- 
 ly, on paper at least, because X requires now fewer energy units per unit 
 of final output. Of course, the deeper conservation question is unre- 
 solved but it suffices to state that X's decision, in the national in- 
 terest with respect to conservation, should be predicated on the issue of 
 minimizing the sum of energy inputs in the total of all manufacturing steps. 
 This thus requires a method to evaluate total (direct plus indirect) energy 
 required to produce a unit of final output. In the above we have defined 
 indirect energy as the sum of all energy inputs due to prior manufactures, 
 shippers, supplies and the like.

Previous Studies 
 
 The determination of total energy in producing a unit of final output 
 has long been a topic of discussion, but its determination has been elusive. 
 First attempts have amounted to tampering with and making ad hoc adjust- 
 ments on available direct energy figures. Specifically, a direct energy 
 study in a plant is achieved by metering or counting all forms of direct 
 energy purchased such as electricity (KWH), propane (gallons), natural gas 
 (therms or CCF's), fuel oil (gallons), and possibly steam (BTU's). In 
 order to reduce these to a common unit, BTU's are usually selected. 
 Unfortunately, the conversion factor selected for electricity is often 
 at the discretion of the user. The plant manager prefers to use 3^1^ BTU/KWH 
 from the heat equivalent in physics, however the concerned environmentalist 
 wishes to use 10,000 or 11,000 BTU/KWH which is the usual amount of fossil 
 fuel heat value required by a previous manufacturer, in this case the 
 electrical power utility. Obviously, the net difference is substantial 
 and the adjustment is made so as to make the direct energy seem more 
 realistic. Actually, this is where the attempt to include indirect energy 
 usually stops. 
 
 Now, if a concerned plant manager, of, say, a pencil factory, wished 
 to actually perform a total (direct plus indirect) energy analysis on his 
 manufacturing facility or plant, he might contemplate doing the following. 
 
 He would contact each previous supplier and determine the direct energy 
 supplied per unit of say, wood, glue, pencil lead, paint, erasers, sheet 
 metal. Now, each of these manufacturers would need to, in turn, calcu- 
 late their direct energy and then, contact each of their previous suppliers. 
 
 -3- 
 
The paint manufacturer would, for example, have to contact his suppliers 
 of spirits, dyes, resins, and the like. This, of course, would be the case 
 for the suppliers of glue, pencil lead, etc. It is not difficult to imagine 
 that this procedure leads to a number of problems. In summary, the main 
 difficulties are 
 
 1. The attempt to backtrack to each supplier and to their 
 suppliers, ad nauseum leads one to an overwhelming book- 
 keeping task with regard to the geometric progression of 
 numbers until reaching the original mines, farms, and forests. 
 
 2. The geometric progression backward leads one outside of one's 
 domain of authority in that many (or most) companies refuse 
 to respond to inquiries regarding manufacturing process in- 
 gredients, quantities, and other proprietary data. 
 
 3. The backward search, involves some inquiries, possibly, back 
 
 to the original pencil manufacturer in that his company supplied 
 pencils to the paint manufacturer, the glue factory, and so forth. 
 This phenomena constitutes implicit loops and thus it is diffi- 
 cult to resolve which came first, the pencil or the paint. 
 
 The above cited difficulties obviate all direct energy backtracking, 
 except in all but the simplist and vertically arranged industries. 
 Other techniques for total energy based on physics and theoretical 
 values have been considered, however, in order to become workable, signi- 
 ficant inaccuracies occur because of the estimation procedures required.

In what follows, a summary of the theory behind energy intensity is given. 
 A more extensive description of the basics of the theory, as well as its 
 limitations and assumptions, can be found in a series of CAC reports 
 [1], [2]. 
 
 THEORY 
 
 By definition, the total output of an industry or a sector is the sum 
 of its sales to other industries plus its sales for final consumption. 
 Mathematically, this definition is described by the following equation. 
 
 N 
 X J = I, X JK + Y j (1 > 
 
 IV— 1 
 
 where 
 
 X* = Total output of »th sector in dollars. 
 
 X* = Amount of product • sold to sector K in 
 Jiv J 
 
 dollars . 
 
 Y* = Amount of product sold to final consumption 
 in dollars. 
 
 N = Total number of sectors. In this study 367 sectors 
 have been used which conforms to previous works in 
 this area [3], [h]. 
 By retaining the same line of reasoning, the total energy embodied 
 in a sector's output is equal to the sum of all indirect energy embodied 
 in its purchased inputs from other sectors plus energy extracted from 
 
 -5- 
 
earth by that sector. Thus

 where 
 
 P = Energy types (i.e. which are defined as coal, crude petroleum, 
 refined petroleum, natural gas and electricity, respectively). 
 
 e.p = P type energy intensity of sector i 
 
 E* = P type energy extracted from earth by sector • . 
 
 Theoretically, e._ represents the P type of energy needed to pro- 
 duce one unit of product i if all inputs were obtained domestically. 
 Treatment of the role of the imports and exports in total energy analysis 
 is straightforward and is presented in the previously cited references. 
 It has been shown in previous works, however, that the energy impact 
 of noncompetitive imports is negligible. Thus, only competitive im- 
 ports need be considered in a total energy analysis. 
 
 The approach described so far has a direct relationship to -the 
 well known input-output theory through the definition of a technologi- 
 cal coefficient matrix A which, in this case, is equal to 
 
 X. T 
 A. T = -l£ (k) 
 
 Throughout this study, the matrix A is assumed to be independent of 
 time and scale which is a commonly used assumption of static input-output 
 theory. The errors associated with the assumption of static coefficients 
 
 -6- 
 
and methods to minimize them are discussed briefly later and are, in 
 addition, the subject of continued investigation. 
 
 The energy dependence of a given sector on the rest of sectors 
 of the economic unit can be best understood by defining a set of energy 
 input coefficients, as below, 
 
 . . e Pi X iJ (5) 
 
 PiJ ~ e PJ X J 
 
 where, G^, •, is defined to represent; the total amount of energy type P 
 
 rlu 
 
 required to produce one unit of product • , in that a percentage 
 Gp • entered through *'s purchase of i . 
 
 Thus, with the introduction of the above definition, the equation 
 (2) becomes 
 
 5 N 5 E • 
 
 1 l G pij + l r^F = x (6) 
 
 p=i i=i PlJ p=i £ pj x j 
 
 The theory that is explained above is applicable to any economic 
 unit, e.g., the U.S. economy, a state economy, a group of industries pro- 
 ducing a similar item, a corporation, a single plant, etc. The Energy 
 Research Group at CAC has applied this theory to the U.S. economy by 
 using the data base collected by the Department of Commerce. The 
 results for the years 1963 and 19&7 are available in various CAC 
 publications. The publication CAC Document 105, [3], for example, 
 contains the detailed analyses of energy use in the 367 commercial and 
 industrial sectors of the U.S. economy in 1963. Sectors are also 
 ranked according to several energy use criteria like direct energy 
 and energy intensity. Another related CAC publication is the document 
 
 -7- 
 
lUO, [^]» which presents a more recent improved method of calculating 
 energy intensity. Reference [k] contains recalculated 1963 values and 
 1967 values for the first time. Because the historical data for two 
 times is now available, researchers have focused considerable attention 
 on the time varying behavior of the linear model coefficients and on 
 the task of extrapolating the energy trends into the future for a par- 
 ticular sector. 
 
 D ESCRIPTION OF GENERAL PROCEDURE 
 
 The input-output approach described above can be applied to a single 
 plant's total energy and labor analysis. Due to the homogenity of the 
 U.S. industrial society, it is reasonable to assume that a single plant's 
 inputs, energy wise, are approximately the same as the national energy 
 and labor coefficients. Specific figures are available for the years 
 1963 and 1967. Each coefficient in the University of Illinois model re- 
 presents the inherent energy (and labor) required by each sector to bring 
 its product to final demand. The energy coefficient matrix is a 357 x 357 
 matrix and its units are BTU/$ except for the five energy sectors which 
 are dimensionless. Thus the data concerning the purchased inputs for 
 a plant, except for its energy inputs, must be in terms of dollar figures. 
 In order for a firm to obtain a total energy balance in a fixed time per- 
 iod all input purchases made by the plant are to be classified in one of 
 the economic sectors found in Table 1. If difficulty arises in assign- 
 ing a particular purchase to a sector, one may refer to the Standard 
 Industrial Classification manual [5] which gives a much more general 
 description of where products are assigned. The numbering code in the 
 SIC can then be converted to particular sectors by utilizing the extreme 
 
 -8- 
 
right hand column of Table 1. 
 
 Because the energy coefficients are based on producers' price data, 
 all purchases must be converted to the producers ' price and thus trade 
 and transportation margins must be applied to the appropriate input 
 sectors. 
 
 As mentioned above, the total energy coefficient matrix is avail- 
 able for the year 1967 at the latest . Thus , dollar input purchases of 
 the plant must be deflated to this base year. The best price deflators 
 appear in the "Survey of Current Business", [6], This journal publishes 
 the implicit price deflators for most of the sectors of U.S. economy in 
 its July edition every year. The "Monthly Labor Review", [7], has also 
 price deflators for a large number of sectors and they are presented 
 under SIC format. Similarly, in the labor intensity analysis, the 
 change in productivity between the year in question and the base year 
 must be taken into account. Hence, direct and indirect labor inputs 
 to the plant must be multiplied by the productivity index which can 
 be found in the reference [7]. 
 
 After preparing the data in the above manner what remains is to 
 multiply the dollar figures of each input purchase by its corresponding 
 energy and labor coefficient to get the energy and labor levels embedded 
 in that particular purchase. In particular, application of the equation 
 (6) yields the sectorwise percentage impact of the five energy sectors 
 and labor on the plant's energy and labor flow.

APPLICATIONS AND CONCLUSIONS 
 
 The theory has "been applied to a number of selected industries. 
 Three different selected industries are discussed below. In each case, 
 as the analysis shows, the energy and labor content of the unit of output 
 entered into plant mostly as indirect energy due to the purchase of supplies, 
 materials and other inputs. Again, in each case, indirect energy and labor 
 concentrated at certain of the sectors. This, of course, suggests that 
 efforts to conserve energy most effectively should be directed at reducing 
 these indirect inputs. 
 
 In the first case an iron foundry plant producing a variety of general 
 purpose castings is investigated. In Fig. (l), 19&7 national average 
 energy flow of the iron foundry sector is given. The national average 
 figures should be compared to the actual plant figures which are shown in 
 Fig. (2). As it can be seen, the energy inputs are larger at certain spots 
 with similar percentages. Most of the zero values appearing in the energy 
 flow of the actual plant are due to lack of data, but were assumed & priori 
 to negligible. According to the analysis this particular plant is doing 
 better energy wise than an average foundry because its primary energy 
 intensity (BTU/1967 $) is less than the national average figure. In ad- 
 dition to energy figures, Fig. (2) gives labor analysis of the same plant. 
 It indicates, for example, that in the case of a wage increase in the 
 primary metal sector, this particular plant will be faced with the prob- 
 lem of increasing its dollar expenditure by a predictable amount for the 
 associated input purchases. This, in turn, may force the plant manager 
 to increase the price of the product manufactured by the plant under study.

 Fig. 5. INPUT PURCHASES OF THE IRON FOUNDRY 
 
 -15- 
 
Fig. (3) shows the annual sectorwise input purchases of this iron foundry 
 in dollars. When this study was going on, the plant was planning to change 
 one of the processes in the production line. Fig. (k) shows the energy 
 map of the same plant if the planned process change is carried on. The 
 analysis shows the plant will achieve a degree of energy savings in natu- 
 ral gas sector. Thus this kind of total energy analysis gives an idea to 
 the decision maker, such as the plant manager, to decide on the possible 
 energy savings through certain process changes. Fig. (5) shows the pro- 
 jected annual input purchases of the iron factory if the process change 
 is implemented. 
 
 The second industry investigated in this study is a soap factory. 
 The energy analysis of the factory yielded an energy map similar to the 
 1967 national average energy map of the cleaning preparations sector in 
 which soap production falls. Fig. (6) and Fig. (7) show national average 
 and actual plant energy flow, respectively. In Fig. (8) annual input 
 purchases of the soap plant is given. 
 
 Finally, energy and labor analysis of a paint manufacturing plant 
 is presented. A comparison between the national paint production energy 
 flow shown in Fig. (9) and the actual plant energy flow shown in Fig. 
 (10) results in the same conclusions as stated above. Fig. (ll) gives 
 the dollar input purchases of the paint plant . 
 
 This study has shown that the input-output energy and labor analysis, 
 as given above, closes the gap between decision makers and the problems 
 associated with energy and labor flows in an economic unit. An industry 
 can lessen its dependence, for example, on critically short energy types 
 by making practical substitutions from high energy intensive materials

and services purchased "by the plant to low energy intensive ones. Hence, 
 the industry will ideally be able to reduce the energy intensity of its 
 outputs in spite of fluctuations and other changes in the energy supply 
 situation. 
 
 Appendix A contains a brief user's handbook which summarizes the steps

 CALCULATIONS FOR A SAMPLE PLANT 
 
 The method described earlier in this study will be applied to a 
 plant which is assumed to purchase all its inputs needed to operate 
 the plant from seven different sectors of the 367 level eaonomy . It 
 is again assumed that 100 units of output were produced by this plant 
 in 1974. Let the same plant purchase the following amount of inputs 
 in 1974.

 An analysis in the accounting department of the plant has shown 
 that the plant paid the following amount, for railroad transportation 
 and wholesale trading in purchasing its inputs.

 where the last two rows are now the railroad transportation sector and 
 the wholesale trade sector with sector numbers 320 and 330 respectively. 
 The total energy coefficients of the seven input sectors can be selected 
 from the national data prepared by CAC for the year 1967. Therefore, 
 the total energy coefficient matrix for this plant is; 
 
 e =

 Now, all the input purchases will be deflated back to 1967 using 
 the ratio between 1967 IPD'S and 1974 IPD'S. Hence, the deflated input 
 purchases become

 It is know that 121443.9 BTU equivalent of coal and 88102.62 BTU 
 equivalent of electricity entered directly into the plant. Then, 
 percentage of the coal energy entered directly becomes; 
 
 % Direct coal = 4590000 [q * 100-0 = 2.64 
 
 and similarly for electricity;

 Similar calculations can be easily done for total labor analysis 
 of the same plant. From reference [7], it is found that output per 
 man-hour in manufacturing sector has increased to 129.2 in 1974 from 
 100.0 in 1967. Hence, the productivity index is equal to 1.292. The 
 total labor put into the production in 1974, then, becomes 
 
 1.292 - (x T . L) = 0.005928 man-year

Labor intensity is equal to the total labor divided by the total 
 output. Thus, 
 
 Labor intensity = 0.592 8>10~ man-year/unit output
