Roof integrated solar chimneys use solar radiation to heat air and induce natural ventilation through a house. They can improve the performance of roof integrated photovoltaic arrays by removing heat absorbed by the panels, and enhance buoyant free cooling at night. This paper studies an...

Photovoltaic (PV) solar energy is a promising source of electricity generation, but still at a relatively high cost. Nevertheless, distributed photovoltaic generation does not compete for land use, as it is incorporated into existing buildings, and should be analyzed from the standpoint of the...

This article analyses the current state of the debate over competition for land use, by means of an index of the main arguments in favor and against the production of liquid biofuels and the impacts on food production. Based on this index, an analytic framework is constructed to establish the...

The availability and reliability of wind power depend a great deal on current and future climate conditions, which may vary in light of possible global climate change (GCC). Long-term energy planning, however, does not normally take possible future GCC into consideration, which may turn out to...

This study analyses the Concentrated Solar Power (CSP) potential in Brazil and evaluates the impact caused by a large-scale integration of this alternative into the Brazilian electricity system in the long term (horizon 2040). Four types of CSP plants with parabolic troughs (simple plants,...
