A GIS Based Methodology in Renewable Energy Sources Sustainability

The exploitation of renewable energy sources has assumed a significant role, especially in an integrated vision of problems concerning energy policies, The 2009/28/EC Directive of the European Parliament and Council has indicated ambitious energy and climate change objectives for 2020 (according to the so-called “EU2020 Strategy”): greenhouse gas emissions reduction for 20%, renewable energy increase for 20%, improvement in energy efficiency for 20%. The aim of this paper is to present a GIS based methodology able to support decision-making in energy supply from Renewable Energy Sources (RES), focusing on two specific casestudies: Photovoltaic (PV) and Wind energy. To decide what type of renewable energy font is the best choice for a specific territory, it’s important to know the local energetic situation, exploring the potential renewable energy sources available in that specific area, deciding what is the territory more compatible/sustainable among them, and if it’s exploitable by suitable environmental and economic point of view. The methodology is largely directed towards the development of a tool to support siting decision. A GIS Based Methodology in Renewable Energy Sources Sustainability
