This emerges from a study published in the international journal <strong>Sustainable Production and Consumption<\/strong> in which researchers from Politecnico di Milano analysed the potential environmental impacts of a floating offshore wind farm undergoing authorisation off the coast of Sicily.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The analysis included the phases of procurement of materials, transport of components, assembly and installation with specialised vessels, maintenance during operation, disassembly and end-of-life.<\/p>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<blockquote class=\"wp-block-quote is-style-large is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Overall, the results of the analysis provide a rough indication, which is useful for becoming aware of the environmental loads of a renewable electricity generation system and comparing it with other energy sources.<\/p>\n<\/blockquote>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph translation-block\">Results show that comparing 1 GWh of energy taken from the national grid with 1 Gwh of energy produced by the wind farm, the <strong>overall impacts of wind power are significantly reduced<\/strong> for almost all impact categories analysed: in the \u2018climate change\u2019 category, the benefit is a 92% reduction in impacts, and worsening is only observed in the \u2018abiotic depletion\u2019 category (+95%). Furthermore, this technology would allow to avoid generating energy from fossil fuels, and therefore, as the results show, related investments would be quickly repaid in terms of greenhouse gas emissions and energy, in 2 and 3 years, respectively.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Scientific literature is still insufficient when it comes to life cycle analysis (LCA) of offshore wind farms with large turbines (over 15 MW) installed on floating structures reflecting recent industry developments and current market trends. However, in order to assess their true environmental sustainability, it is important to analyse renewable electricity generation technologies from a life-cycle perspective.<\/p>\n\n\n\n<p class=\"wp-block-paragraph translation-block\">Authors of this study are, <strong>Mario Grosso<\/strong>, professor in Solid Waste Management and Treatment; <strong>Lucia Rigamonti<\/strong>, professor in Methodologies for Life Cycle Thinking; and <strong>Gaia Brussa<\/strong>, researcher at the Department of Civil and Environmental Engineering.<\/p>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>","protected":false},"excerpt":{"rendered":"<p>Gli&nbsp;impianti eolici offshore, sui quali sono riposte grandi aspettative per la decarbonizzazione del sistema elettrico, portano&nbsp;vantaggi ambientali per tutto il loro ciclo di vita. \u00c8 quanto emerge da uno studio [&hellip;]<\/p>\n","protected":false},"author":29,"featured_media":35606,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[9],"tags":[],"class_list":["post-35603","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cat_ricerca"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.7 -
