This paper estimates the impact of a hypothetical change in Spain's energy mix on a number of productive sectors. The change would be brought about by substituting power generation from natural gas with generation from biomass. The total amount of electricity supplied has been calculated to...

Wind energy potential in Iberia is assessed for recent–past (1961–2000) and future (2041–2070) climates. For recent–past, a COSMO-CLM simulation driven by ERA-40 is used. COSMO-CLM simulations driven by ECHAM5 following the A1B scenario are used for future projections. A 2 MW rated...

Generation expansion planning (GEP) is the problem of determining the optimal strategy to plan the construction of new generation plants while satisfying technical and economic constraints. Over the past few years, the environmental issues have become a society concern and the Clean Air Act...

The purpose of this study was to determine the opinions of secondary school students in Turkey regarding renewable energy resources. To this end, a 26-item questionnaire, developed by Kılınç et al. [1], was administered to a total of 445 students in seventh and eighth grades. In addition,...

In this study, the technical effectiveness of solar cooling and heating was investigated for typical low-rise residential building in the subtropical Hong Kong. Since water heating was required for domestic hot water supply rather than space heating, a separate or an integrated provision of...

A model for pressure-retarded osmotic (PRO) power systems is described. The model considers several non-ideal phenomena including internal and external concentration polarization, local variation due to mass transfer, pressure losses along membrane surfaces and other losses throughout the...

Biomass in the form of crop residues and firewood is a major energy source for rural households in China. A survey conducted in the provinces of Shanxi, Zhejiang, and Guizhou shows that 37 percent of rural households use bioenergy for heating and cooking and that bioenergy accounts for 18...

The media shapes and is shaped by public sentiment of emerging technologies. One way to gauge the societal acceptance levels of an emerging technology, such as geothermal energy technology in Australia, is to analyse how the technology is reported in the media. This study identified the benefits...

The continuous growth in size, complexity and energy density of data centres due to the increasing demand for storage, networking and computation has become a worldwide energetic problem. The emergent awareness of the negative impact that the uncontrolled energy consumption has on natural...

One of the features that characterize renewable energy sources is their variability and intermittency. Intermittency covers both the predictable and unpredictable variations of their power outputs and uncertainty in the power availability. To overcome the drawback of intermittency, special...
