This paper studies the non linear relationship between energy prices, natural resources rent opportunities and renewable energy consumption under different economic growth rates for OPEC member countries during the 2005-2016 period. Using a panel smooth transition regression (PSTR) model, our findings prove a non-linear relationship between renewable energy consumption and the rate of economi...
This paper investigates the potential of Romanian renewable energy across energy production and consumption definitions. Moreover, it presents a model that estimates the regional evolution of renewable energy diffusion, focusing primarily on hydro energy. Statistics showed that Romanian consumers have a key role in developing the renewable energy market, while it is also very important to ensur...
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...
abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...
Renewable energy systems (RES) have a vital role in a country’s rural and comprehensive development programs. Renewable resources for the generation of electricity (e.g., wind, solar, geothermal, etc.) are typically most abundant and practical resources for development in rural areas. Such green development plans create an opportunity for rural electric utilities that are at a geographical adva...
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...
