Analysis of the energetic dynamism between solar and wind energy available in the south of Brazil

Based on the concept of sustainability, which covers the energy issue as well as its rational use from natural resources, conventional sources do not meet the real requirements of the current production methods. In that context the west region of Parana state in Brazil presents a vocation for developing projects that involve energy production from alternate sources such as biomass, water, wind energy and solar. Thus, the aim of this research was to verify the behavior of solar and wind sources in the city of Cascavel, Parana, under different time series of a weather station, subjecting them to quantitative and qualitative analyses of their available energy, by using a statistical approach with Spearman’s correlation coefficients (CC). Solar radiation and wind speed were observed. The correlation coefficients used in the analyses of behavior among alternative sources showed weak correlation with independence between variables in all parameters. Solar energy availability was proportionally more representative than wind availability in all periods assessed, mainly between inter seasonal averages. Key words: Energy availability, renewable sources, correlation coefficients, clean energy.
