knowledge of energyconsumption has many uses in industry. factors that are energy dependent have already been studied hence decision making on them are easier. energy demand studies of industry helps us to learn factors that are responsive to this demand. therefore planners can use these collected data in their decision making using the above factors. another use of energy demand can be used as...

tinuously increasing and now accounts for about one third of the total electrical energy produced in Europe. Many individuals would be interested in saving energy (and thus also carbon dioxide as well as money), but they lack information on their consumption. Indeed, feedback on household electricity usage is typically only provided by monthly (or even annual) utility bills and therefore remain...

Integrating residential photovoltaic (PV) power generation and energy storage systems into the Smart Grid is an effective way of utilizing renewable power and reducing the consumption of fossil fuels. This has become a particularly interesting problem with the introduction of dynamic electricity energy pricing models, since electricity consumers can utilize their PV-based energy generation and ...

Industry constitutes a substantial share of the energy and fuel consumption in energy systems. Types and patterns of usage within different industrial sectors are diverse. In this paper, we illustrate the energy and fuel use in Danish industry by 24 end-uses and 20 fuels and provide hourly profiles for electricity, space and process heating. The heat profiles are based on measured natural gas c...

Human behavior has the positive and negative impact on ecosystem. To study the interaction between ecosystem and behavior system, per-capita energy ecological footprint (EEF) is selected as the ecosystem threshold. Elasticity coefficient of environmental investment (ECEI) and elasticity coefficient of energy consumption (ECEC) represent the positive and negative human impact on ecosystem, respe...

1.0 Overview In 2009, the electricity consumption in Portugal was 49.9 TWh, which represents a reduction of 1.4% in demand, the first decrease since 1981. By the end of December 2009, Portugal had a renewable energy capacity of 9,093 MW, which represents 51% of the total installed capacity (1). The energy generation by the renewable power plants during this year corresponded to 33% of the gener...

Iran is a large producer of agricultural products. Irrigation water resources are limited and the water use efficiency is low. The micro irrigation system (MIS) is a versatile management tool that can increase water productivity. Although micro irrigation has a lot of advantages, some of its disadvantages are its difficult and time-consuming design. Economical analysis of the design is one of t...

This study describes the performance evaluation of an energy management system, based on electricity consumption, for a Gen 6 Thin Film Transistor Liquid Crystal Display (TFT-LCD) panel plant. Of the various production lines and facility systems, the array system and the compressed dry air consumed the most electricity of 21.8% and 19.8%, respectively, while the public utility used only 1.6% of...

The main objective of this work is to develop a method for sizing window area based on the consumption of electricity in commercial buildings, when integration of daylight and artificial light with hybrid ventilation is considered. The method allows the estimation of the potential for electricity savings and the evaluation of the daylighting performance. Models operating with artificial and nat...
