Methodological insights on Life Cycle Assessment of solar energy technologies
2012
Renewable energies are reliable sources to move the world toward a sustainable energy economy, to achieve the emission reduction targets and to face the shortage of worldwide fossil fuels reserves. A reliable energy and environmental profile of renewable energy technologies (RETs) may not leave out considerations on the impacts of the background system, including also the production, use, and disposal of such systems. In this context the Life Cycle Assessment (LCA) is an established methodology to estimate the energy and environmental benefits and drawbacks of RETs and to identify components and life cycle stages having the largest impacts. In the present Chapter the authors focus on the an…
A Comparison of Solar and Conventional Pavements Via Life Cycle Assessment
2023
The sustainable and green development of roads is lately receiving significant attention. As a multi-functional road capable of both accommodating traffic loads and generating clean energy, solar pavements exhibit a strategic opportunity for the future path of development in the road engineering. Although solar pavements have significant environmental benefits during their operation, they can lead to increased carbon emissions during the process of material preparation, construction, maintenance, etc. Therefore, it is essential to implement the framework of Life Cycle Assessment (LCA) to investigate their potential environmental impacts and/or benefits. Hence, this paper systematically anal…
