Proper evaluations of this two-way 5 August 2014 climate–renewable energy relationship require detailed information of the geographical location of the Accepted 26 September 2014 renewable energy fleets. However, this information is usually provided as total amounts installed per administrative region, especially with respect to future planned installations. To help overcome this Keywords: limiting issue, the objective of this contribution was to develop the so-called CLIMIX model: a tool that Wind power performs a realistic spatial allocation of given amounts of both photovoltaic (PV) and wind power Solar photovoltaic power installed capacities and evaluates the energy generated under varying climate conditions. This is done Spatial distribution of renewable energy over a regular grid so that the created scenarios can be directly used in conjunction with outputs of plants ° fi Europe climate models. First, we used the 0.44 resolution grid de ned for the EURO-CORDEX project and Euro-Cordex applied the CLIMIX model to spatially allocate total amounts of both unreported 2012 and future 2020 PV and wind power installations in Europe at the country level. Second, we performed a validation exercise using the various options for estimating PV and wind power production under the created scenarios that are included in the model. The results revealed an acceptable agreement between the estimated and the recorded power production values in every European country. Lastly, we estimated increases in power production derived from the future deployment of new renewable units, often obtaining non-direct relationships. This latter further emphasizes the need of accurate spatially-resolved PV and wind power scenarios in order to perform reliable estimations of power production. & 2014 Elsevier Ltd.

Introduction The various data used in this work are listed in Section 2. Section 3 provides a detailed description of the CLIMIX model, as A spectacular deployment of new renewable energy installations, well as of the assumptions made for the creation of the 2012 and in particular solar plants and wind farms, is taking place in both 2020 PV and wind power scenarios. Section 4 presents the created developing and developed countries [1]. The commitment on low scenarios along with the results of the validation and application carbon energies as a substitute of traditional fossil energy resources exercises. Finally, Section 5 summarizes and discuss the main has a double motivation and objective. On the one hand, the conclusions. investments devoted to exploit the free, local and renewable resources, such as solar radiation and wind, are expected to rebound positively on economy by both promoting the local employment and favoring 2.
