Low-carbon power comes from processes or technologies that produce power with substantially lower amounts of carbon dioxide emissions than is emitted from conventional fossil fuel power generation. It includes low carbon power generation sources such as wind power, solar power, hydropower and nuclear power. 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, 36.4% of electricity generation comes from low-carbon sources. As of 2018 the largest low-carbon energy sources globally were hydropower and nuclear power, with the latter providing over 50% of low-carbon power alone in United States and European Union.

Measurement of life-cycle greenhouse gas emissions involves calculating the global-warming potential of energy sources through life-cycle assessment. These are usually sources of only electrical energy but sometimes sources of heat are evaluated. The findings are presented in units of global warming potential per unit of electrical energy generated by that source. The scale uses the global warming potential unit, the carbon dioxide equivalent, and the unit of electrical energy, the kilowatt hour (kWh). The goal of such assessments is to cover the full life of the source, from material and fuel mining through construction to operation and waste management.
The Blythe Mesa Solar Power Project, also known as the Blythe Solar Energy Center, is a 235 megawatt (MWAC) photovoltaic power plant near the city of Blythe in Riverside County, California.
