摘要: All renewable energy systems make some contribution to climate change. This is due the emission of greenhouse gases from fossil fuels combusted for their construction, and as back-up during operation. Accurate calculation gas emissions per kilowatt hour electricity difficult, but an important part policy making planning. Calculation methodologies results different grid-scale generation are presented in this paper, with emphasis on solar thermal systems. Both material inventory financial-based methods employed, compared other recent studies. For most plants, have a strong dependence capacity factor, fuel, size plant. typical show that approximately 90 g CO2 equivalent released kWh generated over lifetime
