2021 Texas power crisis; 2021 United Kingdom natural gas supplier crisis and 2021 United Kingdom fuel supply crisis; 2021 global energy crisis. The record-high energy prices were driven by a global surge in demand as the world quit the economic recession caused by COVID-19 pandemic, particularly due to strong energy demand in Asia.

A power outage (also called a power cut, a power out, a power blackout, power failure or a blackout) is a loss of the electric power to a particular area. Power failures can be caused by faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit , cascading failure ...
A 2016 report by Oil Change International, concludes that the carbon emissions embedded in the coal, oil, and gas in currently working mines and fields, assuming that these run to the end of their working lifetimes, will take the world to just beyond the 2 °C limit contained in the 2015 Paris Agreement and even further from the 1.5 °C goal.
The MIT report calculated the world's total EGS resources to be over 13 YJ, of which over 0.2 YJ would be extractable, with the potential to increase this to over 2 YJ with technology improvements – sufficient to provide all the world's energy needs for several thousand years. [30] The total heat content of the Earth is 13,000,000 YJ. [29]
UHV transmission and a number of UHVAC circuits have already been constructed in different parts of the world. For example, 2,362 km of 1,150 kV circuits were built in the former USSR, and 427 km of 1,000 kV AC circuits have been developed in Japan (Kita-Iwaki powerline). Experimental lines of various scales are also found in many countries. [7]
As of 2022, more than 10,000 power plant and energy storage projects were awaiting permission to connect to the US grid — 95% were zero-carbon resources. New power lines can take 10 years to plan, permit, and build. [33] Traditional power lines use a steel core surrounded by aluminum strands (Aluminium-conductor steel-reinforced cable).
EIA projected power demand will rise to 4,086 billion kilowatt-hours in 2024 and 4,165 billion kWh in 2025. That compares with 4,012 billion kWh in 2023 and a record 4,067 billion kWh in 2022.
Curtailment is a loss of potentially useful energy, and may impact power purchase agreements. [5] [6] However, utilizing all available energy may require costly methods such as building new power lines or storage, becoming more expensive than letting surplus power go unused. [7] [8] [9] [10]
