Abstract:
In the last decades, the international energy demand has risen greatly due to the world’s population
growth and the economic development of some big countries (e.g. China, India, Indonesia). The
intensive use of fossil fuels is recognized as unsustainable in the long-term period. In this framework,
renewable energies represent important sources in order to satisfy the energy demand in a sustainable
way. European Union (EU) promotes the use of renewable energy sources (RES) to reduce
greenhouse gas (GHG) emissions, to increase energy independence and to promote the renewable
industry. Renewable energy policy must take into account the technical aspects of energy production
and also the environmental, economic and social aspects, following an integrated approach.
Consequently, sustainability assessment has become a fast developing research field and impact
assessment tools – based on methods that take in consideration stakeholders’ opinions and expectations
– are commonly used to support policies or projects implementation. Sustainability Impact
Assessment (SIA) is a tool that supports decision-makers in identifying potential impacts of possible
policy actions. Environmental, economic and social aspects related to renewable energies are often
analyzed with sectorial approaches. To overcome this gap, it is fundamental to develop practical
instruments useful for an integrated assessment considering environmental, technical-logistics,
financial and social parameters of renewable energy systems. Starting from these considerations,
this research investigates the indicators useful to support the SIA of a policy, a plan or a single action
related to a renewable energy system. Social and economic dimensions and related indicators are
analyzed, also including indicators which straddle between socio-economic and environmental sector.
A comprehensive in-depth literature review has been made in order to create a database of criteria
and indicators. After creating the database, authors selected 308 suitable indicators: 93 relating to the
economic dimension, 152 to the socio-political and cultural one and 63 to the social-environmental
dimension. Furthermore, indicators were aggregated into three main impact dimensions (economic,
social-political and social-environmental) and six general criteria. Finally, some recommendations are
given to contribute at developing new indicators for the assessment of effects of renewable energy
systems on sustainability.
