Life-cycle greenhouse-gas emissions of energy sources
Comparisons of life-cycle greenhouse gas emissions or global warming potential is an attempt to calculate the global-warming potential of electrical energy sources by doing a life-cycle assessment of each energy source and presenting the findings of the assessment in units of global warming potential per unit of electrical energy generated by that source; which uses the global warming potential unit, the Carbon dioxide equivalent(CO2e) and the unit of electrical energy, the kilowatt hour(kWh). The assessments attempt to cover the full life of the source, from material & fuel mining, construction, to operation and waste management.In 2014, the Intergovernmental Panel on Climate Change harmonized the Carbon dioxide equivalent(CO2e) findings of the major electricity generating sources used worldwide by assessing the findings of hundreds of individual scientific assessment papers published from each energy source.It is important to note that for all technologies, advances in efficiency and therefore reductions in CO2e since the time of publication have not been included. For example, the total life cycle emissions from wind power may have reduced since publication, similarly, due to the timescales over which the studies were conducted, nuclear Generation II reactor's CO2e results are presented and not the global warming potential of Generation III reactors, which are presently under construction in the United States and China. Other limitations found in the literature of these comparisons of energy sources include missing life cycle phases and where to define the cut-off point in the global warming potential the energy source may cause when in a combined electrical grid in the real world, as opposed to the established practice of simply assessing the energy source in isolation.
