The 2021–2023 global energy crisis began in the aftermath of the COVID-19 pandemic in 2021, with much of the globe facing shortages and increased prices in oil, gas and electricity markets. The crisis was caused by a variety of economic factors, including the rapid post-pandemic economic rebound that outpaced energy supply, and escalated into a widespread global energy crisis following the Russian invasion of Ukraine. The price of natural gas reached record highs, and as a result, so did electricity in some markets. Oil prices hit their highest level since 2008.
Higher energy prices pushed families into poverty, forced some factories to curtail output or even shut down, and slowed economic growth. It was estimated in 2022 that an additional 11 million Europeans could be driven to poverty due to energy inflation. Europe's gas supply is uniquely vulnerable because of its historic reliance on Russia, while many emerging economies have seen higher energy import bills and fuel shortages.
The COVID-19 pandemic in 2019–2020 caused a rapid drop in energy demand and a corresponding cut in oil production, and despite the 2020 Russia–Saudi Arabia oil price war, OPEC responded slowly to the demand recovery under new normal, causing a supply-demand imbalance. The 2021–2022 global supply chain crisis further stressed the delivery of extracted petroleum.
Additionally, as Europe sought to replace Russian gas, it bid up prices of U.S., Australian, and Qatari ship-borne liquefied natural gas (LNG), diverting supply away from traditional LNG customers in Asia. Because gas frequently sets the price at which electricity is sold, power prices soared as well. Both LNG producers and importers rushed to build new infrastructure to increase LNG export/import capacity, but these costly projects take years to come online.
In December 2020, after months of restrictions, China fully blocked coal imports from Australia, which was China's largest source of imported coal.

The 2021 United Nations Climate Change Conference, more commonly referred to as COP26, was the 26th United Nations Climate Change conference, held at the SEC Centre in Glasgow, Scotland, United Kingdom, from 31 October to 13 November 2021. The president of the conference was UK cabinet minister Alok Sharma. Delayed for a year due to the COVID-19 pandemic, it was the 26th Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC), the third meeting of the parties to the 2015 Paris Agreement (designated CMA1, CMA2, CMA3), and the 16th meeting of the parties to the Kyoto Protocol (CMP16).
During 2022 and 2023 there were food crises in several regions as indicated by rising food prices. In 2022, the world experienced significant food price inflation along with major food shortages in several regions. Sub-Saharan Africa, Iran, Sri Lanka, Sudan and Iraq were most affected. Prices of wheat, maize, oil seeds, bread, pasta, flour, cooking oil, sugar, egg, chickpea and meat increased. The causes were disruption in supply chains from the COVID–19 pandemic, an energy crisis (2021–2023 global energy crisis), the Russian invasion of Ukraine and some effects of climate change on agriculture.
The 1970s energy crisis occurred when the Western world, particularly the United States, Canada, Western Europe, Australia, and New Zealand, faced substantial petroleum shortages as well as elevated prices. The two worst crises of this period were the 1973 oil crisis and the 1979 energy crisis, when, respectively, the Yom Kippur War and the Iranian Revolution triggered interruptions in Middle Eastern oil exports. The crisis began to unfold as petroleum production in the United States and some other parts of the world peaked in the late 1960s and early 1970s.
