Transformation to wind and solar achievable with low indirect GHG emissions

Different low carbon technologies including wind and solar energy, and fossil carbon capture and sequestration (CCS) differ greatly when it comes to indirect greenhouse gas emissions in their life cycle. This is the result of a comprehensive new study conducted by an international team of scientists, now published in the journal Nature Energy. Contrary to some arguments, the researchers found that wind and solar energy are more favorable when it comes to life-cycle emissions. They also show that a full decarbonization of the global power sector by scaling up these technologies would induce only modest indirect greenhouse gas emissions—and hence not impede the transformation towards a climate-friendly power system.
