ENERGY PRODUCTIVITY INDEX FOR COMPANIES

JUNE 13, 2016

ClimateWorks Australia has  published the Energy Productivity Index for Companies, and it  illustrates the importance of energy productivity performance to both profitability and the reduction of industrial greenhouse gas emissions.

The new guide analyses the energy productivity of industrial companies and provides investors’ guide, information about the percentage of profits that could be saved in the different sectors, as well as other useful resources and guides.

The energy productivity is  described or defied as the amount of economic output per unit of energy input.

Water Productivity - Why Waste Water? - Eliminate The Water Waste





"Why Waste Water?" is the theme of World Water Day 2017.
http://www.worldwaterday.org/theme/
http://www.unwater.org/news-events/news-details/en/c/468902/

The theme is relevant to industrial engineers? What is the water consumption in industry? Is the consumption efficient? Are industrial engineers doing analysis of water consumption. Resource use analysis or productivity analysis is the first part of IE study. The second part of coming out with more productive processes.

Industry uses 19% of the global consumption of water.
Iron & Steel industry uses 95,000 to 150,000 liters of water for producing a tonne of steel.

The uses of water

Only 1% of water used by humans (compared to the global sum of all withdrawals) is for drinking, washing and cooking. An additional 10% is calculated for all other domestic uses (toilet flushing etc). Industry uses 19% and the rest, a massive 70%, is used by agriculture for irrigation, drawing water from rivers, lakes and underground water strata.

The  concept  of  water  productivity  (WP) in Agriculture


The  concept  of  water  productivity  (WP)  is  offered  by  Molden  et  al. (2003)  as  a  robust
measure of the ability of agricultural systems to convert water into food. While it has been
used  principally  to  evaluate  the  function  of  irrigation  systems  as  the  amount  of  ‘crop  per
drop’, it seems reasonable to extend the concept toinclude other types of livelihood support,
such as mixed cropping, pasture, fisheries or forests.

Opportunities for Improvement (eds J.W. Kijne, R. Barker and D. Molden)

The Water Productivity term plays a crucial role in modern agriculture which aims to
increase yield production per unit of water used, both under rainfed and irrigated conditions.
This can be achieved either by 1)increasing the marketable yield of the crops for each unit of
water transpired, 2) reducing the outflows/ losses, or 3) enhancing the effective use of
rainfall, of the water stored in the soil, and of the marginal quality water.

A systematic and quantitative approach to improve water use efficiency in agriculture
Theodore C. Hsiao, Pasquale Steduto, Elias Fereres Pages 209-231

Causes of the differences in efficiency in each step, going from water delivery to soil water
extraction, transpiration, photosynthesis, and conversion to crop biomass and yield, and to animal product are discussed in the paper. Based on an equation quantifying the impact of changes in efficiency of component steps on the overall efficiency, it is concluded that generally, it is
more effective to make modest improvements in as many steps as possible than to concentrate efforts to improve one or two steps.



Beyond irrigation efficiency
Marvin E. Jensen Pages 233-245

This paper describes how efficient management of water for irrigation requires a full understanding of water balance for the field, irrigation project, or river basin under consideration. Development of the classic term irrigation efficiency is summarized along with recent modifications such as effective irrigation efficiency which reflects the efficiency of the system in terms of the amount of water effectively consumed by the system, taking into account outflows water as not wholly “wasted” or “lost” from river basins and that can be recovered and made available for use in the context of the water balance of the river basin. This makes it possible to develop accounting procedures for water use, or water accounting based on the water balance approach for a water basin and analyzing the uses, depletion, and productivity of water.

Economics, adoption determinants, and impacts of micro-irrigation technologies: empirical results from India

R. E. Namara, R. K. Nagar, B. Upadhyay Pages 283-297

The study by Namara et al. (analyses of micro-irrigation adoption and impacts in selected localities of Maharashtra and Gujarat states in India) indicates that micro-irrigation technologies result in significant productivity improvement and hence economic gain over the traditional method of surface irrigation.  The most important
determinants of micro-irrigation adoption identified by the study include access to groundwater, the prevailing cropping pattern (proportion of staples vs. high value crops), level of education, availability of cash, the social stratum of the household, and the wealth or poverty status of the
farmer. The majority of the current adopters of low-cost micro-irrigation systems are the richer section of the farming population. Thus, reducing the cost alone is not yet effective to improve
the outreach of micro-irrigation technologies.

Fluid Intelligence - Productivity - Productivity Science




Total Factor Productivity is an increasing function of ordinary workers’ fluid intelligence.



A Theory of Intelligence and Total Factor Productivity: Value Added Reflects the Fruits of Fluid Intelligence

MPRA Paper No. 43151, posted 7 December 2012


The model of TFP shows that TFP is an increasing function of ordinary workers’ fluid intelligence. It also shows that TFP depends substantially on ordinary workers’ fluid intelligence, and that production is almost impossible without it.


 In this paper, a theory of TFP is proposed, and TFP is suggested to reflect the fruits of human intelligence. That the fluid intelligence of ordinary workers is an important element in TFP is particularly emphasized. Ordinary workers can also create something new (i.e., innovate)  because they have intelligence, just as do researchers and other highly educated or trained employees. Although most innovations of ordinary workers are so minor that they do not become part of the accumulated knowledge of humanity, they are indispensable for production because a large number of minor unexpected problems that ordinary workers must address occur in the process of production.

A model of TFP is formulated on the basis of the finding that ordinary workers’ fluid intelligence is an essential element in TFP. TFP is modeled as a function of fluid intelligence, and item response theory, which is widely used in psychology and psychometrics, is used to specify the functional form. The model of TFP shows that TFP is an increasing function of ordinary workers’ fluid intelligence. It also shows that TFP depends substantially on ordinary workers’ fluid intelligence, and that production is almost impossible without it. Therefore, value added comes from the fruits of humans’ fluid intelligence.
