energy price forecast is the key information for generating companies to prepare their bids in the electricity markets. however, this forecasting problem is complex due to nonlinear, non-stationary, and time variant behavior of electricity price time series. accordingly, in this paper a new strategy is proposed for electricity price forecast. the forecast strategy includes wavelet transform (wt...

abstract i n this paper we investigated total energy consumption and its individual forms (oil, natural gas, electricity, renewable energies and coal) relationship with real gross domestic product (gdp) in iran. we employed hsiao’s (1981) methodology and annual data which cover 1967-2010 for investigation. the empirical findings indicate there is bidirectional causality effect with real gdp and...

-Waste heat from electronic components in information and telecommunication equipment is not trivial. Especially, contemporary Integrated Circuits(IC’s) in computers, servers and telecommunication equipment dissipate more amount of total energy as heat energy to the environment. Additionally, coolers have to be used in large amount to dissipate the heat from those equipments. Companies often sp...

Speed and availability of information, delivered in past years by Internet technologies, made it easier for any company to outsource primary activities, which resulted in unbundling of many companies’ traditional value constellations into networks of different companies. In the electricity power sector decomposition of the value constellation is not only enabled by technological advances such a...

abstract in this study, we applied recently developed panel unit root and cointegration techniques to examine the long-run real income per capita and price elasticities for demand of electricity in selected middle east and north african (mena) countries using an annual data series from 1990 to 2011.our main finding from the panel analysis is that the demand for electricity is highly price elast...
