For mankind to be able to continue life at a high level of comfort and satisfaction, first of all it is necessary to provide a significant amount of energy. Electrical and mechanical energy as well as thermal energy in the form of heat or domestic hot water over 75% is ensured by combustion of fossil fuels, which generates a large amount of gaseous and solid pollutants. In the last decades, mankind has searched for new sources of primary energy that, transformed into electricity or heat, do not pollute the environment, under the generic name of renewable energy. Currently, the most used renewable energy source is wind energy, which has grown, mainly due to the financial support policies adopted in most countries in the world. Making an onshore / offshore wind turbine involves a series of energy-consuming activities, both in wind turbine components manufacturing and building on a given location. Wind turbines also affect the environment, directly and indirectly throughout their life cycle. In addition, the decommissioning of these colossi with growth tendencies has a number of difficulties, especially for offshore winds, generating enormous quantities of waste. Depending on the type of turbine and its power, the work involves research, design, manufacturing and experimentation. These activities, as well as the actual realization of wind turbines in the current technology, are energy consuming and produce a series of waste in fuctoning and especially decommissioning. In this paper, an assessment of the embodied energy and energy produced by a wind turbine at an onshore site is made. [ABSTRACT FROM AUTHOR] |
