Do fossil fuels remain essential to U.S. energy supply and grid reliability?
Core argument: Carbon-based fuels — oil, coal, and natural gas — supplied 81% of U.S. energy demand and 71% of electrical demand in 2020.
In 2020, carbon-based fuels, including oil, coal, and natural gas, supplied 81% of the U.S. energy demand and 71% of electrical demand, underscoring their critical role in the economy. Despite rising natural gas prices, coal generation surged, with a 37% increase in the Midcontinent Independent System Operator (MISO) and a 42% rise in the Southwest Power Pool (SPP) in June. This shift highlights coal's role as a price shock absorber and its importance in maintaining grid reliability amid increasing reliance on intermittent renewables. The Biden administration's push for renewable energy, while reducing fossil fuel reliance, risks undermining energy security and economic stability. As rolling blackouts and grid challenges persist, maintaining a balance between renewable additions and existing fossil fuel capacity is crucial to avoid potential energy crises and ensure a reliable power supply for the growing economy.


Steve note: So according to theAEIcarbon based fuels (so coal, natural gas and petroleum) generated 2691 billion kilowatthours of electricity in 2000,71%of total US electrical generation that that year.
Note this includes transportation. The number is 71% for electrical generation from the EIA
