United States power stations by type and nameplate capacity Generation by source [14] The United States is the world's second-largest producer and consumer of electricity. It generates 15% of the world's electricity supply, about half as much as China. [80] The United States produced 3,988 TWh in 2021. Total generation has been flat since 2010.

Projections from NEMS are provided at the national level; however, regional results are generally available consistent with the modules' regional definitions. For example, energy consumption by fuel and sector is reported for the nine Census Divisions, the geographic definition used by the four end-use energy demand modules. [5]
The base load [2] (also baseload) is the minimum level of demand on an electrical grid over a span of time, for example, one week. This demand can be met by unvarying power plants [ 3 ] or dispatchable generation , [ 4 ] depending on which approach has the best mix of cost, availability and reliability in any particular market.
The duck curve is a graph of power production over the course of a day that shows the timing imbalance between peak demand and solar power generation. The graph resembles a sitting duck, and thus the term was created. [2] Used in utility-scale electricity generation, the term was coined in 2012 by the California Independent System Operator. [3] [4]
The 1973 and 1979 energy crisis had caused petroleum prices to peak in 1980 at over US$35 per barrel (US$129 in today's dollars). Following these events slowing industrial economies and stabilization of supply and demand caused prices to begin falling in the 1980s. [ 26 ]
[31]: 22 Total energy demand continues to increase through to 2050. [31]: 23 Total energy investment remains at about US$3 trillion per year. [31]: 49 The Announced Pledges Scenario (APS) assumes all national energy and climate targets made by governments are met in full and on time. The APS is associated with a temperature rise of 1.7 °C in ...
Domestic energy consumption refers to the total energy consumption of a single household. Globally, the amount of energy used per household may vary significantly, depending on factors such as the standard of living of the country, the climate, the age of the occupant of the home, and type of residence.
