Energy is one of the primary inputs in textile processing industries that have a significant impact on the cost of a cotton product. The energy cost-share is reported between 5-10% of the total production cost of woven cotton fabric in textile factories of developed countries. However, it is far higher in developing countries. This study aims to contribute to the understanding of energy use and...

The present study attempts to investigate the potential relationship between input energies, performance production of greenhouse basil, and greenhouse gases emitted from this product. The data were collected from 24 greenhouses using a questionnaire and verbal interaction with farmers. Results of the study showed that the total input energy and total output energy for basil production were 119...

This study investigates the constructs and related theories that drive social capital in energy sector from the intention perspectives. This research uses theories of ‘social support’ and ‘planned behaviour’ alongside satisfaction and perceived value to propose a research model that drives social capital for energy sectors in Malaysia. The model reveals that the Theories of Planned Behaviour (T...

Many cities in the world are involved with air pollution and environmental pollution. The consumption of fossil fuels in buildings has an enormous impact on the pollution. About 40% of the total energy is spent on heating, cooling and lighting of buildings. The use of solar energy is one of the ways that reduce the thermal load of buildings. One of the factors that affect this utilization is th...

Many models of economic growth exclude materials, energy and other intermediate inputs from the production function. Growing environmental pressures and resource prices suggest that this may be increasingly inappropriate. This paper explores the relationship between intermediate input intensity, productivity and national accounts using a panel dataset of manufacturing subsectors in the USA over...

The indexes of multifactor productivity for two-digit manufacturing sectors prepared by the Bureau of Labor Statistics for sectors in manufacturing have been revised and extended to cover the 1949–92 period. These indexes, also called the “KLEMS” multifactor measures, compare changes in output to changes in a composite of all the inputs used in production—capital, labor, energy inputs, nonenerg...

ational statistics on coal-mining productivity show that—except during the 1970s—coal mines have become steadily more efficient. More coal is removed per hour of work, causing a drop in both mining costs and coal prices. However, a new Energy Laboratory study suggests that those national statistics do not tell the whole story. When the researchers analyzed productivity data for more than ninete...

In this paper Malmquist productivity index(MPI) for decision making unit(DMU) with interval data has been evaluated.A method for assessing Malmquist productivity index using cost efficiency also has been developed.The applicability of the methods developed is illustrated in the context of the analysis of groups of teaching of university performance.

Iran’s vision statement 1404, maintains that the nation needs to uphold its productivity and innovative spirit in order to enhance the economy’s competitiveness. Having considered the implications of the vision statement 1404 for the country’s sustainable development, in this paper, an attempt is made to measure Iran’s energy efficiency compared to the neighboring countries and some other natio...

Whether it be a rugby team or a rescue crew, ensuring peak group performance is a primary goal during collective activities. In reality, however, groups often suffer from productivity losses that can lead to less than optimal outputs. Where researchers have focused on this problem, inefficiencies in the way team members coordinate their efforts has been identified as one potent source of produc...
