There is an indispensable need to develop geothermal technologies to supplement the long-term energy needs of Pakistan to a significant level. Geothermal energy is one of the oldest, most versatile and also most common form of utilization of renewable energy. Pakistan is rich in geothermal...

The paper provides a critical overview of water desalination using geothermal resources. Specific case studies are presented, as well as an assessment of environmental risks and market potential and barriers to growth. The availability and suitability of low and high temperature geothermal...

The ability to discover and utilize a reliable source of renewable energy is vital in order to reduce the effects of global warming and to decrease and/or eliminate reliance on fossil fuel. Recently, countries around the world have been recognizing the immediate need to tackle the current energy...

In this review, general features of the renewable energy sources in the North African upper zone have been studied. The primal renewable sources of energy have been identified in Algeria, Morocco and Tunisia. Taking into account concordances and divergences of the different actors in the region,...

An overview is presented on the last decade of geothermal heating by ground source heat pumps (GSHPs) in Europe. Significant growth rates can be observed and today's total number of GSHP systems is above 1 million, with an estimate of about 1.25 million mainly used for residential space heating...

Fossil fuel reserves (coal, oil, natural gas, etc.) diminish day by day. In addition, rapid advancement of technology causes an increase in the amount of energy needed. This emerging situation resulted in ever increasing importance of renewable energy sources, and various systems are being...

An experimental system was developed and tested in order to investigate the energetic performance of a solar photovoltaic system (PV) assisted earth-to-air heat exchanger (underground air tunnel) that is used for greenhouse cooling at the Solar Energy Institute, Ege University, Izmir, Turkey....

In the current study the savings of CO2 emissions due to the use of ground source heat pump (GSHP) systems was investigated in comparison to conventional heating systems. Based on a subsidy program for GSHP systems in southwest Germany, the regional, average, and total CO2 savings of 1105...

The aim of this paper is to review the current status and prospects of the renewable energy sources that are more suitable for the production of electricity, and to present the views of the EURE Group on the role electricity utilities could play in deploying generating plants based on these...
