Spain exhibits a high level of energy dependence and has significant solar energy resources. These two facts have given rise to the prominence that renewable energy, particularly solar photovoltaic technology, has enjoyed in recent years, supported by a favorable regulatory framework.

The exploitation of renewable energy resources poses great challenges regarding the manner in which they can be integrated into the modern electrical distribution infrastructure.

Electric power losses are constantly present during the service life of wind farms and must be considered in the calculation of the income arising from selling the produced electricity. It is typical to estimate the electrical losses in the design stage as those occurring when the wind farm...

The present research explains and analyses a technically feasible and economically profitable alternative for concentrated solar power plants recently constructed in Spain. The proposed solution is hybridization with biogas. The method is more economical than investment in salt storage systems,...

The growth of the world energy demand, the limited fossil fuel reserves and the increasing greenhouse gas emissions require improvements in energy-generation technologies. Specifically, urban wind energy is a source with great potential that is currently being wasted.

The purpose of this paper is to highlight water consumption as a key design parameter in determining the most convenient cooling system and selecting the most appropriate location for Solar Parabolic Trough (SPT) plants. Considering the importance of water in guaranteeing environmental...

The Spanish economy faces two key issues. The first of these is the significant reliance on non-renewable energy, which reached 76.4% and was 22 points over the European Union average. Secondly, the threat that the fee deficit poses to the sustainability of the National Grid. This fact is...

A diesel or gasoline vehicle heating is produced by the heat of the engine coolant liquid. Nevertheless, electric vehicles, due to the fact that electric motor transform directly electricity into mechanical energy through electromagnetic interactions, do not generate this heat so other method of...

In the need to find efficient manageable and available energy, economically and environmentally, there is a clear shift to renewable energy sources, but currently it does not seem to provide the final solution. Cogeneration, in all its variations, has to be a part of the solution to this...
