Coal electrical generation (black line), compared to other sources, 1949–2016 Coal power generation in 2011 by state. Coal generated about 19.5% of the electricity at utility-scale facilities in the United States in 2022, down from 38.6% in 2014 [2] and 51% in 2001. [3]
From 2015 to 2020, although coal generation hardly fell in absolute terms, some of its market share was taken by wind and solar. [27] In 2020 only China increased coal power generation, and globally it fell by 4%. [27] However, in 2021, China declared that it limited coal generation until 2025 and subsequently phase it out over time. [39]
This is a list of the 212 operational coal-fired power stations in the United States. Coal generated 16% of electricity in the United States in 2023, [1] an amount less than that from renewable energy or nuclear power, [2] [3] and about half of that generated by natural gas plants. Coal was 17% of generating capacity. [4]
Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry , it is the stage prior to its delivery ( transmission , distribution , etc.) to end users or its storage , using for example, the pumped-storage method.
Part of the utility's transition away from coal-powered electric generation, the shutdown of the power plant is expected to be complete in late 2025. Move away from coal started in 2005.
System loss within the grid includes use in the generation process and transmission losses, as well as unaccounted loads. For 2021, this amounted to 203 TWh, or 5.3% of grid generation. Electricity used directly at the commercial or industrial level added 139 TWh, so total consumption was 3,945 TWh. [86]
The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...
The largest and most long-term effect of coal use is the release of carbon dioxide, a greenhouse gas that causes climate change. Coal-fired power plants were the single largest contributor to the growth in global CO 2 emissions in 2018, [155] 40% of the total fossil fuel emissions, [9] and more than a quarter of total emissions.
