Analysis of wind and irradiation data for possible alternative energy use at the University Gozo Campus

Abstract

It is now considered a fact that increased greenhouse gas emissions will result in serious climate change consequences. Reducing the world's fossil fuel dependence via the installation of alternative energy systems will play a key role in averting future climate change catastrophes. An assessment of the in situ wind and solar irradiation characteristics present at the University of Malta- Gozo Campus in Xewkija, Gozo was carried out with a view to installing hybrid wind and solar powered systems within the building grounds. The setting up of two 15 kW horizontal axis wind turbines at 18 m height and a 21 kWp double-axis tracking photovoltaic system (occupying around 65% of available roof area) was estimated to generate approximately 74,000 kWh/yr. Such electricity generation would make up for, and exceed, an estimated future consumption of 55,000 kWh/yr. Should only one turbine be installed, and should the photovoltaic system be installed on fixed mounts, an estimated 47,000 kWh/yr would be generated. Installing this renewable energy system would also help Malta reach its 2020 commitment with the European Union that 10% of the final energy consumption must be sourced from alternative energies.
