Geothermal resources in Italy and world-wide: scientific debate and market evolution - This paper describes the state of the art in development and utilization of geothermal resources in Italy and Tuscany. Departing from the geological peculiarities of this region, which have contributed to Italy’s leading role in technological innovation since the beginning of geothermoelectric power generation (GPG), recent evidences from the market and scientific community are here analyzed in order to answer the question whether the economic downturn will put geothermal energy on the back burner, or if it will function as a catalyst for change. The first section explores the role of geothermal energy within the renewable energy mix. After an introduction on the strengths and weaknesses of the Italian energy system, the evolution of the matches between different types of geothermal resources (high, medium and low enthalpies) and technologies is analyzed from an economic, technical and environmental point of view. Here, the evolution of the regulatory framework emerges as one of the main driving forces behind incremental innovation and the spreading of technologies. The move towards sustainability seems to stimulate the market in spite of the barriers to entry linked to capital intensiveness and the risks related to geothermal investments. Beside the growth of relationships between industrial actors, public administration and scientific community, the analysis identifies the downscale of plants, the integration with other "renewables" and the industrial integration as the main next challenges in the field of geothermal competitiveness. To this end, the implementation of such new tools for territorial management as the ones based on LCA (Life Cycle Assessment) and SMCE (Social Multi Criteria Evaluation) is expected to stimulate further improvements and innovations. The second section analyzes the present regulatory framework at the communitarian, national and local level and the allocation of economical resources to research and development in particular in relation to the distribution and characteristics of the geothermal resources. The specialization of Italy in GPG appears not to be adequately represented within European programmes and the Tuscany region is still considered not a leading market by the investors in geothermal heat pumps and geothermal district heating. Both according to the communitarian prescriptions and the requests from local actors, a few scenarios for the development of guidelines, certification schemes and regulations are here described. These elements are consistent with the purpose of sustainability and competitiveness of local economic activities. On the basis of these evidences, the third section describes the perspectives of development of medium and low enthalpy utilizations in Italy. According to the present financial incentives schemes and the predicted modifications in relevant regulations (i.e. city plans, building regulations, etc.), a booming growth of installations is expected. This geothermal "green new deal" is pulled by the increasing number of life-long learning programmes for professionals (i.e. geologists) and, even more, is expected to be pulled by the implementation of risk management tools and certification schemes. As result, the analysis sets a roadmap for addressing the needs of geothermal actors and removing the barriers to successful investing in this local and renewable energy resource. When we return to the initial question, it seems to be the moment for changing attitude towards energy production and to win back competitiveness and sustainability in the geothermal market.
