Renewable energy deployment is arguably the best way to address the challenges of climate change. This paper investigates convergence in the contribution of renewable energies to the energy supply for a broad set of countries for the period 1990 to 2010. Using a nonlinear time-varying...

The increasing utilization of renewable energy sources (RES) is a major energy policy strategy in many countries worldwide. Germany is a forerunner in the deployment of RES and has ambitious goals for the future. The support and use of renewables affects the economy: It creates business...

Natural gas is a finite resource that may be estimated directly, through geophysical methodologies, or indirectly, through historical production data. The rapid growth in consumption of this limited natural resource, strictly connected to the oil economy, may lead to its imminent depletion and a...

Upgrading biogas, i.e., the removal of CO2 from CH4 is an attractive regenerative energy as it is supplied continuously. Conventional upgrading techniques such as absorption or adsorption require significant amounts of energy and require equipment of large size. Hence, we give an overview on gas...

This review describes the situation and the varying potential of energy supply utilization of countries in the Organization of Islamic Conference (OIC). This exercise reveals that the increase in energy consumption is associated with economic growth and population expansion. The...

This paper presents a review of existing and emerging wind power technologies in light of the evident trends of the industry, and describes the challenges these technologies will face if wind turbines were to become a significant and reliable source of clean energy of the future. Apart from...

Energy storage systems (ESS) have the potential to make a significant contribution to planning and operation practises in power systems. While ESS can be used to provide multiple benefits in the power sector, widespread use has been restricted by high technology costs, lack of deployment...

The growing demand for energy, commitments taken to reduce greenhouse gas emissions, fossil fuel depletion and other issues enforced to accept the decision to analyze financing issues of renewable energy sector worldwide. This paper addresses two financing issues – financing channels and...

The objective of the study is to examine the relationship between macroeconomic factors (i.e., population growth; urbanization, industrialization, exchange rate, price level, food production index and live stock production index) and renewable energy in Pakistan over a period of 1975–2012. In...

Uneconomical extension of the grid has led to generation of electric power at the end user facility and has been proved to be cost effective and to an extent efficient. With augmented significance on eco-friendly technologies the use of renewable energy sources such as micro-hydro, wind, solar,...
