renewable energy is derived from the natural processes that are replenished constantly. in its various forms, it derives directly from the sun, or from the deep heat generated from the earth. it isdefined as the electricity and heat being generated from solar, wind, ocean, hydropower, biomass, geothermal resources, biofuels, and the obtained hydrogen from the renewable resources. the renewable ...

This paper by using Long-range Energy Alternatives Planning System (LEAP) constructs four different renewable energy scenarios for the Greek transport, energy, and industry sectors. By projecting the demand for renewable energy and the associated resulting carbon dioxide emissions up to the years 2020 and 2030, the paper applies in a second stage data envelopment analysis (DEA) evaluating the G...

This article reviews issues related to the incorporation of non-renewable resources in the theory of economic growth and development. As an o¤shoot of the new growth theory of the last two decades a series of contributions have studied endogenous technical change in relation to resource scarcity. We discuss the main approaches within this literature and consider questions like: How is the new l...

The discrete time –cost trade-off problem (DTCTP) is one of the main aspects of project scheduling. In DTCTP , we treat cost as a non-renewable resource and the availability of renewable resource per period has been neglected. It was recently suggested that the quality of project should also be taken into consideration. Therefore, when renewable resources and quality are considered, the traditi...

Title of Document: OFFTAKE STRATEGY DESIGN FOR WIND ENERGY PROJECTS UNDER UNCERTAINTY Xinyuan Zhu, Philosophy of Doctorate, 2014 Directed By: Associate Professor, Qingbin Cui, Department of Civil & Environmental Engineering Energy use from wind, solar, and other renewable sources is a public policy at the federal and state levels to address environment, energy, and sustainability concerns. As t...

The objectives of this research were to investigate influences of energy inputs and energy forms on output levels and evaluation of CO2 emissions for hazelnut production in Guilan province of Iran. Moreover, the sensitivity analysis was done by marginal physical productivity (MPP) method for energy inputs and energy using linear regression. Initial data were collected from 120 orchar...

the aims of this study were to investigate the energy flow and its modeling in shablon cultivar of plum production in golestan province of iran. data were collected through questionnaires and also interviews with producers. cobb-douglass model and sensitivity analysis were used to determine the effects of energy inputs on plum yield. the results revealed that the total energy inputs and energy ...

nowadays using of new energies in the form of dispersed resources in the worlds is wide spreading. in this article we will design a dispersed production source in the form of a solar/wind hybrid power plant in order to supply the energy of a residential unit according to a sample load pattern. the aim of aforementioned design is to reduce its costs in a period of 20 years. in order to optimi...

use of fossil energy provides greenhouse gases emissions and therefore global warming phenomenon and the incidence of further consequences such as expanding deserts and blasting the dust storms in the middel east, including iran. taking advantage of renewable energy is the most appropriate solution to prevent greenhouse gas emissions. ahvaz region in the southwest of with a population of 133812...
