Based on power law (PL), a novel method is proposed to extrapolate surface wind speed to the wind turbine (WT) hub height, via assessment of wind shear coefficient (WSC), by only using surface turbulence intensity, a parameter actually regarded as a merely critical one in wind energy studies. A...

Increasing knowledge on wind shear models to strengthen their reliability appears as a crucial issue, markedly for energy investors to accurately predict the average wind speed at different turbine hub heights, and thus the expected wind energy output. This is particularly helpful during the...

In the framework of regional renewable energy policies, starting from 2008 the Tuscany Regional Authority promoted the “WIND-GIS” project aimed at assessing the large-scale wind potential of Tuscany region, Italy. This goal was achieved by developing an integrated Geographic Information...

In the present work a computation of wind shear coefficients (WSCs) based on 1-h measured wind data has been performed by three stations located over coastal sites in Southern Italy, i.e., Brindisi (BR), Portoscuso (PS) and Termini Imerese (TI). Wind observations have been collected through a...

Among all uncertainty factors affecting the wind power assessment at a site, wind speed extrapolation is probably one of most critical ones, particularly if considering the increasing size of modern multi-MW wind turbines, and therefore of their hub height. This work is intended as a...

An accurate wind shear model is crucial to extrapolate the observed wind resource from the available lower heights to the steadily increasing hub height of modern wind turbines. Among power law (PL) and logarithmic law (LogL), i.e., the two most commonly used analytical models, the former was...

Many governments in Central and Eastern European Countries (CEECs) have offered significant incentives in order to attract foreign investments, motivated by expectations on possible spillover benefits. FDI is usually perceived as a vehicle for transferring technology not only across national...

offered significant incentives in order to attract foreign direct investments (FDI), being motivated to do so by expectations of possible spillover benefits. Using an unbalanced panel of firm level data in Bulgaria, Poland and Romania over the 1995-2003 period, we examine the impact of foreign...

In this paper we analyse whether and to what extent MNEs can generate positive externalities for the host economies by allowing for spatial dependence patterns in TFP growth rates at sectoral and regional level. In order to achieve this research objective we use spatial econometric techniques,...

Several papers have proven that the institutional environment of the receiving country can influence the choice to establish an FDI. Property rights theory suggests that contract enforcement matters differentially across sectors. This paper is the first attempt to test whether institutions...
