Increasing activities of geothermal development especially in the last three years result in a geothermal boom in Turkey. Not only the addition of new sites, but also updating the data of existing ones increased the currently identified capacity significantly. With the discoveries of 13 new...

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...

Heating is a major requirement in many regions, and growing energy demands and pollutant emissions have allowed unconventional heating technologies to be considered, including geothermal. Geothermal heat pumps are reviewed, including heat pump technology, earth connections, current world status...

The temperature response in the soil surrounding multiple boreholes is evaluated analytically and numerically. The assumption of constant heat flux along the borehole wall is examined by coupling the problem to the heat transfer problem inside the borehole and presenting a model with variable...

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...

The impacts of recurrent droughts have increased vulnerability and reduced the adaptive capacity of the people living in arid and semi-arid lands (ASALS) of Kenya. Current interventions are short-term and curative in nature, hence unsustainable. Some of the most arid and semi-arid lands are...

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...

The purpose of this survey is about to analyze the heating coefficient of performance (COP) of geothermal district heating systems. Actual system data are taken from the Salihli GDHS, Turkey. The collected data are quantified and illustrated in tables, particularly for a reference temperature...

Access to modern energy services is key to economic development and progress towards millennium development goals (MDGs). Yet only 20% of Kenyan population of which 5% are rural residents have access to electricity. The study focuses on East Pokot and Marigat Districts, commonly known as Baringo...
