Life Cycle Assessment (LCA) of Electricity Generation Technologies: Overview, Comparability and Limitations

Renewable and Sustainable Energy Reviews
Dec 2013
Turconi, Roberto, Alessio Boldrin, and Thomas Astrup
This study presents a review of 167 case studies involving the life cycle assessment (LCA) of electricity generation based on hard coal, lignite, natural gas, oil, nuclear, biomass, hydroelectric, solar photovoltaic (PV) and wind to identify ranges of emission data for GHG, NOx and SO2.

Greenhouse gases, climate change and the transition from coal to low-carbon electricity

Environmental Research Letters
16 Feb 2012
Myhrvold NP and Caldeira K
A transition from the global system of coal-based electricity generation to low-greenhouse-gas-emission energy technologies is required to mitigate climate change in the long term. The use of current infrastructure to build this new low-emission system necessitates additional emissions of greenhouse gases, and the coal-based infrastructure will continue to emit substantial amounts of greenhouse gases as it is phased out. Furthermore, ocean thermal inertia delays the climate benefits of emissions reductions. By constructing a quantitative model of energy system transitions that includes life-cycle emissions and the central physics of greenhouse warming, we estimate the global warming expected to occur as a result of build-outs of new energy technologies ranging from 100 GWe to 10 TWe in size and 1–100 yr in duration. We show that rapid deployment of low-emission energy systems can do little to diminish the climate impacts in the first half of this century. Conservation, wind, solar, nuclear power, and possibly carbon capture and storage appear to be able to achieve substantial climate benefits in the second half of this century; however, natural gas cannot.
