Renewable Energies (Energias
Renováveis)
INTRODUCTION – THE ROLE OF RENEWABLE ENERGIES: energy consumption – repartition by source and use in Portugal and EU; renewable energy sources – solar, wind, biomass, hydro, geothermal, wave; renewable energies and sustainable development – present and future position in the energetic context THERMAL SOLAR ENERGY: solar geometry and solar resources; calculation of incident solar radiation on inclined surfaces; thermal solar collectors without or with low concentration – types and applications; water heating systems (domestic and pools), space heating, space cooling, process heating; simplified calculation methods – f-chart, -chart, ,f-chart PHOTOVOLTAIC SOLAR ENERGY: solar cells and its efficiency; photovoltaic collectors and integration in buildings; electricity production systems; simplified calculation methods – PV f-chart. WIND ENERGY: principles – origins, landscape effects, rotor aerodynamics; decentralized electricity production and its integration in the national grid system ECONOMIC AND ENVIRONMENTAL ASPECTS OF RENEWABLE ENERGY SYSTEMS: cost of useful energy; economic and environmental evaluation methods; financial support for the use of renewable energies. Objectives To acquire knowledge related to the main renewable energy technologies. Simplified methods for thermal and photovoltaic systems. Economic and environmental evaluation of renewable energy systems. |
