本文严格筛选了153项涵盖广泛的风能和太阳能光伏（PV）发电技术的生命周期研究，以确定41项最相关，最新，严格，原始和完整的评估，以便确定其温室气体（GHG）排放曲线的动态。从整体来看，包括最初的材料提取、制造、使用和处置/退役，这41项研究表明，风能和太阳能系统都与温室气体排放直接相关。因此，它们实际上不是无排放技术。此外，通过突出这些技术的生命周期阶段和物理特征，这些技术是最负责任的排放，可以做出改进，以降低其碳足迹。因此，通过深入研究这些研究的结果及其变化，本文揭示了风能和太阳能设计和部署的最佳实践，可以更好地为电力部门的气候变化减缓工作提供信息。(C)2013爱思唯尔有限公司保留所有权利。
This paper critically screens 153 lifecycle studies covering a broad range of wind and solar photovoltaic (PV) electricity generation technologies to identify 41 of the most relevant, recent, rigorous, original, and complete assessments so that the dynamics of their greenhouse gas (GHG) emissions profiles can be determined. When viewed in a holistic manner, including initial materials extraction, manufacturing, use and disposal/decommissioning, these 41 studies show that both wind and solar systems are directly tied to and responsible for GHG emissions. They are thus not actually emissions free technologies. Moreover, by spotlighting the lifecycle stages and physical characteristics of these technologies that are most responsible for emissions, improvements can be made to lower their carbon footprint. As such, through in-depth examination of the results of these studies and the variations therein, this article uncovers best practices in wind and solar design and deployment that can better inform climate change mitigation efforts in the electricity sector.
