The possibility of developing a machine that would “think” has intrigued human beings since ancient times. Artificial intelligence (AI) systems comprise two major areas, expert systems (ES) and artificial neural networks (ANNs). The major objective of this paper is to illustrate how artificial intelligence techniques might play an important role in modelling and prediction of the performance of...

Current conventional agricultural systems using intensive energy have to be revitalized through new integrated approaches relying on renewable energy resources, which can allow farmers to stop dependence on fossil resources. The aim of this study was determining the amount of input–output energy used in onion (Allium cepa L.) production in Khorasan Razavi province. For this purpose, the data wa...

In the recent years, renewable energy sources are an important component of world energy consumption. GDP is one of the main measures of a country’s economic activity. Most of the studies examine the impact of renewable energy consumption on GDP with single equation model and the others use dynamic panel data. Since the Granger causality analysis’s findings of this paper establish bidirectional...

Developing countries like Iran face increasing energy demands due to population growth and economic expansion. The country has numerous renewable energy resources that account for the majority of its total energy supply. As fossil fuel resources are running out, the government plans to increase its renewable energy share. Many studies have already been conducted on renewable resources. However,...

Energy as one of the factors of production along with labor and capital has an important role in development and social welfare. Due to the pollution of non-renewable resources and its negative impact on welfare, the use of renewable resources can improve social welfare by eliminating pollutants. In this study, the effect of renewable and non-renewable energy consumption on social welfare of de...

The overarching goal of ASES is to inspire an era of energy innovation and to speed the transition to a sustainable energy economy. With growing concerns about global climate change and energy costs, the development of photovoltaic (PV) and solar hot water (SHW) systems has drastically increased in the USA to accommodate the demand for renewable energy sources. Here, we describe a collective ac...

In order to achieve self-sufficiency, increasing national milk production is a priority of the Algerian government. This will increase on-farm demand for electricity supplied primarily from fossil fuels, which contribute to the emissions of greenhouse gases and accelerate climate change. Hence, there is a need for promoting the use of renewable energy and low carbon technologies for the sustain...
