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.{{cite web |url=https://www.energy.gov/eere/iedo/low-carbon-fuels-and-energy-sources-basics |title=What Are Low-Carbon Fuels and Energy Sources and Why Are They Important? |website=U.S. Department of Energy}} The energy transition to low-carbon power is one of the most important actions required to limit climate change.

History
File:Percentage of electricity generation from low-carbon sources in 2019.png
During the late 20th and early 21st century significant findings regarding global warming highlighted the need to curb carbon emissions. From this, the idea for low-carbon power was born. The Intergovernmental Panel on Climate Change (IPCC), established by the World Meteorological Organization (WMO) and the United Nations Environment Program (UNEP) in 1988, set the scientific precedence for the introduction of low-carbon power. The IPCC has continued to provide scientific, technical and socio-economic advice to the world community, through its periodic assessment reports and special reports.{{cite web|url=http://www.ipcc.ch/about/about.htm|title=Intergovernmental Panel on Climate Change Web site|website=IPCC.ch|access-date=1 October 2017|url-status=dead|archive-url=https://web.archive.org/web/20060825110811/http://www.ipcc.ch/about/about.htm|archive-date=25 August 2006}}
Internationally, the most prominent{{According to whom|date=October 2017}} early step in the direction of low carbon power was the signing of the Kyoto Protocol, which came into force on 16 February 2005, under which most industrialized countries committed to reduce their carbon emissions. The historical event set the political precedence for introduction of low-carbon power technology.

Differentiating attributes of low-carbon power sources

There are many options for lowering current levels of carbon emissions. Some options, such as wind power and solar power, produce low quantities of total life cycle carbon emissions, using entirely renewable sources. Other options, such as nuclear power, produce a comparable amount of carbon dioxide emissions as renewable technologies in total life cycle emissions, but consume non-renewable, but sustainable{{cite web|url=http://large.stanford.edu/courses/2012/ph241/chowdhury2/|title=Is Nuclear Energy Renewable Energy?|website=large.Stanford.edu|access-date=1 October 2017}} materials (uranium). The term low-carbon power can also include power that continues to utilize the world's natural resources, such as natural gas and coal, but only when they employ techniques that reduce carbon dioxide emissions from these sources when burning them for fuel, such as the, as of 2012, pilot plants performing Carbon capture and storage.{{cite web|url=http://news.nationalgeographic.com/news/energy/2012/05/120522-carbon-capture-and-storage-economic-hurdles/|archive-url=https://web.archive.org/web/20120525084232/http://news.nationalgeographic.com/news/energy/2012/05/120522-carbon-capture-and-storage-economic-hurdles/|url-status=dead|archive-date=25 May 2012|title=Amid Economic Concerns, Carbon Capture Faces a Hazy Future|date=23 May 2012|website=NationalGeographic.com|access-date=1 October 2017}}
Because the cost of reducing emissions in the electricity sector appears to be lower than in other sectors such as transportation, the electricity sector may deliver the largest proportional carbon reductions under an economically efficient climate policy.{{cite web|url=http://www.issues.org/23.3/apt.html|title=Promoting Low-Carbon Electricity Production - Issues in Science and Technology|website=www.Issues.org|access-date=1 October 2017|url-status=dead|archive-url=https://web.archive.org/web/20130927013232/http://www.issues.org/23.3/apt.html|archive-date=27 September 2013}}

Hydroelectric plants have the advantage of being long-lived and many existing plants have operated for more than 100 years. Hydropower is also an extremely flexible technology from the perspective of power grid operation. Large hydropower provides one of the lowest cost options in today's energy market, even compared to fossil fuels and there are no harmful emissions associated with plant operation.International Energy Agency (2007).
[http://www.iea.org/textbase/papers/2006/renewable_factsheet.pdf Renewables in global energy supply: An IEA facts sheet] (PDF), OECD, p. 3. However, there are typically low greenhouse gas emissions with reservoirs, and possibly high emissions in the tropics.
Hydroelectric power is the world's largest low carbon source of electricity, supplying 15.6% of total electricity in 2019.{{Cite web|url=https://lowcarbonpower.org/type/hydro|title = Understand Hydropower energy through Data | Low-Carbon Power}} China is by far the world's largest producer of hydroelectricity in the world, followed by Brazil and Canada.
However, there are several significant social and environmental disadvantages of large-scale hydroelectric power systems: dislocation, if people are living where the reservoirs are planned, release of significant amounts of carbon dioxide and methane during construction and flooding of the reservoir, and disruption of aquatic ecosystems and birdlife.Duncan Graham-Rowe. [https://www.newscientist.com/article.ns?id=dn7046 Hydroelectric power's dirty secret revealed] New Scientist, 24 February 2005. There is a strong consensus now that countries should adopt an integrated approach towards managing water resources, which would involve planning hydropower development in co-operation with other water-using sectors.

Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into electric current using the photoelectric effect.{{cite web|title=Energy Sources: Solar|url=https://www.energy.gov/energysources/solar.htm|work=Department of Energy|access-date=19 April 2011}}
Commercial concentrated solar power plants were first developed in the 1980s. The 354 MW SEGS CSP installation is the largest solar power plant in the world, located in the Mojave Desert of California. Other large CSP plants include the Solnova Solar Power Station (150 MW) and the Andasol solar power station (150 MW), both in Spain. The over 200 MW Agua Caliente Solar Project in the United States, and the 214 MW Charanka Solar Park in India, are the world's largest photovoltaic plants. Solar power's share of worldwide electricity usage at the end of 2014 was 1%.http://www.ren21.net/wp-content/uploads/2015/07/REN12-GSR2015_Onlinebook_low1.pdf pg31

Tidal power is a form of hydropower that converts the energy of tides into electricity or other useful forms of power.
