The frequent power outages which characterises Ghana's electricity sector have raised serious concerns among policy makers and stakeholders. The causes of this problem have been cited as growing demand and inadequate investment. The objective of this study, therefore, was to identify the factors...

The main objective of the present study is twofold: (i) to analyze thermal loads of the geothermally and passively heated solar greenhouses; and (ii) to investigate wind energy utilization in greenhouse heating which is modeled as a hybrid solar assisted geothermal heat pump and a small wind...

CPG (CO2 Plume Geothermal) energy systems use CO2 to extract thermal energy from naturally permeable geologic formations at depth. CO2 has advantages over brine: high mobility, low solubility of amorphous silica, and higher density sensitivity to temperature. The density of CO2 changes...

The objective of the current study was to assess the technical and economic factors that influence the design and performance of vertical GSHP (ground source heat pump) systems and to evaluate the spatial correlation that these factors have with geographic components such as geology and climatic...

We study the valuation of preferences for small scale initiatives in renewable electricity generation. We analyse the results of a stated choice experiment among 507 respondents in The Netherlands and provide valuations of characteristics of small scale initiatives. Respondents prefer installing...

The continuing increases in oil prices have renewed the argument over the real culprits behind these movements. The growth in demand for oil in international markets, especially from the United States and China, is often identified as the main source of consumption pressure on prices, and thus...

This paper analyzes the evolution of real energy efficiency in the European Union and the attribution across countries of its percent change. Relying on a multiplicative energy intensity approach that is implemented through the Sato-Vartia Logarithmic Mean Divisia Index method, we decompose the...

This study presents a thermal and economic performance analysis of a LT-MEE (low-temperature multi-effect evaporation) water desalination system coupled with an LiBr–H2O ABHP (absorption heat pump). A 60–78% water production increase over a stand-alone LT-MEE run at the same heat source...

This study aims at analyzing the relationship between oil production and economic growth in major oil exporting Eurasian countries; Azerbaijan, Kazakhstan, Russian Federation and Turkmenistan for 1993–2010 periods. Empirical results reveal that oil production and economic growth are...

This study estimates electricity demand functions for Sri Lanka using six econometric techniques. It shows that the preferred specifications differ somewhat and there is a wide range in the long-run price and income elasticities with the estimated long-run income elasticity ranging from 1.0 to...
