Combing windpower and hydropower to decrease seasonal and inter-annual availability of renewable energy sources in Brazil
Schmidt, Johannes; Cancella, Rafael; Junior, Amaro … - 2014
A high share of Brazilian power production comes from hydropower sources. A further expansion of power generation is necessary due to high growth rates in electricity demand. As an alternative to carbon intensive thermal power production and the expansion of hydropower in the ecologically and...

Storage requirements in a 100% renewable electricity system: Extreme events and inter-annual variability
Ruhnau, Oliver; Qvist, Staffan - 2021
In the context of 100% renewable electricity systems, prolonged periods with persistently scarce supply from wind and solar resources have received increasing academic and political attention. This article explores how such scarcity periods relate to energy storage requirements. To this end, we...

Wave power variability over the northwest European shelf seas
Neill, Simon P.; Hashemi, M. Reza - In: Applied Energy 106 (2013) C, pp. 31-46
Regional assessments of the wave energy resource tend to focus on averaged quantities, and so provide potential developers with no sense of temporal variability beyond seasonal means. In particular, such assessments give no indication of inter-annual variability – something that is critical...

Contribution to the study of UV-B solar radiation in Central Spain
Bilbao, J.; Miguel, A. - In: Renewable Energy 53 (2013) C, pp. 79-85
A series of Ultraviolet-B broadband solar irradiance, 280–315 nm, measured during the period 2002–2011 in Valladolid (Spain) is analysed. UV-B daily values follow the pattern of the solar elevation angle. Daily maximum value occurred in June, 50.29 kJ m−2, and minimum, 0.88 kJ m−2,...
