Planning areas correctly\, while respecting e xisting environmental constraints\, is not an easy task and requires the c ollaboration of a panel of experts with different skills.\n\nThe need to s earch for new sites to be allocated to renewable energy generation plants is dictated by the most pressing current events\, the search for non-impac ting energy sources to whose research and development specific points of t he National Resistance and Resilience Plan are dedicated\, to which are ad ded the consequences of the newborn Ukrainian conflict that has definitive ly discovered the problematic relationship-dependence of Italy and Europe with energy supplies from non-European countries. Both issues are pushing the country towards a rapid search for new energy strategies for environme ntal reasons and to make up for natural shortages that require massive imp orts of gas and other resources from abroad. \nIn particular\, the Nationa l Recovery and Resilience Plan (PNRR)\, part of the European Next Generati on EU (NGEU) programme\, a 750 billion euro package allocated by the Europ ean Union to counteract the economic damage caused by the Covid-19 global pandemic\, is an economic plan worth 248 billion euro that Italy can use i n the five-year period from 2021 to 2026 to implement various reforms and repair the damage created by the pandemic crisis. \nThe plan\, presented t o the EU under the name 'Italia Domani'\, envisages investments along thre e main axes: digitalisation and innovation\, ecological transition and soc ial inclusion. These economic interventions are intended to resolve the dr ama caused by the advent of the Sars-Cov2 virus and help solve structural problems in the Italian economy\, accompanying the country towards a path of ecological and environmental transition. It also aims to resolve import ant issues such as territorial\, generational and gender gaps. \nIt is in this context that the national legislation is undergoing a revision\, whi ch has entrusted the regional administrations with the task of identifying the territorial criteria that favour or prevent the establishment of cert ain plants in the various areas of the territory. Each regional administra tion has the right to graduate the criteria according to the specific geom orphologic characteristics of its own territory and therefore the most eff icient procedure would be to verify\, with simulations in GIS environments \, the effect of defining certain criteria on the territory to assess in a dvance which and how many areas could have greater or lesser suitability. On the basis of this consideration\, we proceeded to experiment with the e ffects of the most common constraints by developing a real simulation on t he territory of the Lazio Region.\n\nThe experimentation used the well-kno wn open environment QGIS 3.22\, which made it possible to exploit the poss ibilities offered by the open territorial databases of the Lazio Region.\n It should be noted that the Lazio Region (like most Italian regions) has m ade many spatial data available in open format in recent years. The Europe an directive called "Inspire" gave a boost to the use\, standardisation an d free dissemination of spatial data. It provides for the creation of a Co mmunity data infrastructure that simplifies the sharing between public adm inistrations and user access to spatial information. In Italy\, the direct ive was transposed into Italian law by Legislative Decree no. 32 of 27 Jan uary 2010\, which established the National Infrastructure for Spatial Info rmation and Environmental Monitoring as a node of the Community infrastruc ture. As a result of this implementation\, the National Geoportal was crea ted\, which was followed by the various Regional Geoportals\, such as that of the Lazio region.\n\nThe implementation of the open data in QGIS 3.12 made it possible to identify topological inaccuracies in the files provide d and shared on the Lazio Region site\, which led to necessary decisions s uch as the correction of some polygons that presented errors\, such as the ir overlapping or imperfect closure (the correction of the latter case was suggested by QGis itself\, through the "reopen geometries" function). \nA possible inaccuracy was also found in the "lowland species" and "mountain species" files of the Regional Ecological Network\, which seems to show a n error in the transcription of the relative geodetic datum on the website \, where it is reported as WGS84\, UTM33N and resulting from verifications and overlapping more likely ED50 . Uncategorised areas also emerged in th e file called "PTPR Regione Lazio (Tav. A - Tav. B)" which were however ex cluded from those considered to be unsuitable since a more detailed analys is revealed the area of the Parco della Caffarella in Rome\, which is hard ly conceivable as the site for a wind farm or large-scale photovoltaic pla nt. Extraterritorial areas within the Region's territory belonging to the State of "Vatican City" were also added as "unsuitable".\nThe first result s show that the remaining areas after eliminating all those that are certa inly unsuitable are a limited part of the Region itself. It should be note d that these areas are not definitely suitable areas but those that are no t unsuitable or potentially suitable\, even if further investigation is re quired to ascertain their suitability.\nThe limited extent of the areas re maining after the exclusion of the unsuitable areas suggested that we make an initial estimate of the sustainability of a total conversion to these energy sources for the whole region in order to assess its potential energ y autonomy.\nThe analysis was extended to individual municipalities by com paring average yields per conceivable plant area\, then comparing them wit h inhabitants for an initial estimate of energy needs at least for domesti c use.
