The occurrence of the general relativistic instability, as well as the absence of the intermediate stellar phase, led to the denomination of direct collapse black hole. In other words, these objects collapse directly from the primordial gas cloud, not from a stellar progenitor as prescribed in standard black hole models. [15]
The Senate Committee on Energy and Natural Resources held a hearing in October 2018 to examine "black start", the process of restoring electricity after a system-wide power loss. The hearing's purpose was for Congress to learn about what the backup plans are in the electric utility industry in the case that the electric grid is damaged.

Viral images of a helicopter de-icing a wind turbine said to be in Texas were actually taken in 2015 in Sweden. [48] However, wind energy accounts for only 23% of Texas power output. [ 48 ] Moreover, equipment for other energy sources such as natural gas power generating facilities either freezing up or having mechanical failures were also ...
FE's situational awareness was reduced by the development of faults in its General Electric Harris XA21 energy management system (EMS) from 2:14 p.m. to 2:54 p.m. The alarm and logging software in the control room failed first, followed by some remote terminals and data links, then the primary and backup EMS servers.
14 September—Nigeria—a "total system collapse" resulted in widespread blackouts that affected the entire country. [293] 20 September—Tunisia—a "sudden breakdown" at the Radès power station in the southern suburbs of Tunis caused a nationwide power outage that lasted for up to four hours. [294] 9 December—2023 Sri Lankan blackouts [295]
The 1996 Western North America blackouts were two widespread power outages that occurred across Western Canada, the Western United States, and Northwest Mexico on July 2 and August 10, 1996. They were spread 6 weeks apart and were thought to be similarly caused by excess demand during a hot summer.
An energy crisis or energy shortage is any significant bottleneck in the supply of energy resources to an economy. In literature, it often refers to one of the energy sources used at a certain time and place, in particular, those that supply national electricity grids or those used as fuel in industrial development.
