This is s direct quote from my first link in the story from Yale.edu.

"Coal, oil, and natural gas received $5.9 trillion in subsidies in 2020 — or roughly $11 million every minute — according to a new analysis from the International Monetary Fund.

Explicit subsidies accounted for only 8 percent of the total. The remaining 92 percent were implicit subsidies, which took the form of tax breaks or, to a much larger degree, health and environmental damages that were not priced into the cost of fossil fuels, according to the analysis."

I doubt any Medium writers are doing deep research, but rather depend of reputable news outlets for their source material. This is originally sourced from the International Monetary Fund, Yale University.

Oil subsidies implicit or explicit are designed to shield the consumer from the real price of the fuel.
