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.
The United States has some of the best renewable energy resources in the world, with the potential to meet a rising and significant share of the nation's energy demand. A quarter of the country's land area has winds strong enough to generate electricity at the same price as natural gas and coal. [29]
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 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]
Over this same time period solar( including small scale) has increased by 13.1X and now provides 3.37% of US electric energy needs. Utility scale solar has grown 11.1X over the last decade and in the last eight years of estimating small scale solar it has grown by 5.4X.
Heating degree day (HDD) is a measurement designed to quantify the demand for energy needed to heat a building. HDD is derived from measurements of outside air temperature. The estimated average heating energy requirements for a given building at a specific location are considered to be directly proportional to the number of HDD at that location.
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.
