Low-carbon electricity

Low-carbon electricity or low-carbon power is electricity produced with substantially lower greenhouse gas emissions over the entire lifecycle than power generation using fossil fuels. The energy transition to low-carbon power is one of the most important actions required to limit climate change.

This article is about electricity generation that aims to minimise greenhouse gas emissions. For broader concepts, see sustainable energy.

Low carbon power generation sources include wind power, solar power, nuclear power and most hydropower. The term largely excludes conventional fossil fuel plant sources, and is only used to describe a particular subset of operating fossil fuel power systems, specifically, those that are successfully coupled with a flue gas carbon capture and storage (CCS) system. Globally almost 40% of electricity generation came from low-carbon sources in 2020: about 10% being nuclear power, almost 10% wind and solar, and around 20% hydropower and other renewables.
