Renewable energy sources can solve the problem of energy production in a more environmentally friendly way, mainly due to the low greenhouse gas emissions. Wind energy, and specifically the use of wind in the offshore areas, has been developing rapidly over the last decade on a global scale. Greece is restarting the procedures for the construction of offshore wind farms. As with onshore wind farms, there may be concerns about whether their creation could have a negative environmental impact regardless of the potentially positive impact they have on mitigating climate change.The purpose of this thesis is the life cycle assessment (LCA) of offshore wind farms. LCA is a standardized method that systematically analyzes and records the inputs (materials and energy) and outputs (waste and emissions) that occur throughout the life of a product from the extraction of raw materials, construction / production, use and disposal and which can assess the potential environmental consequences.The case study refers to Offshore Wind Farm planned to be built near a Greek island, where favorable conditions related to the performance of the farm exist and in accordance with the restrictions for navigation, protected areas etc. The LCA will consider different scenarios for the Offshore Wind Farms, as they are formed based on project characteristics such as different depths, different types of foundation. The thesis will assess the carbon footprint, as well as other categories of environmental impact. In addition, the phases and parts of the life cycle that contribute most to these effects will be identified, as well as the options that reduce them.
