I looked for some decent (non-partisan) sources on this [1] and was surprised that the number was so "small" in the US (given how large the industry is): $21bn. But about $290bn worldwide, down from $500bn in 2013. So they're on the downward trend which is promising.

Whenever we see the multi trillion dollar numbers, they are counting "implicit" subsidies to me feels a bit more vague. I'm not sure how this compares to renewable energy subsidies. But they work in increasing adoption. I'd be ok with having those sunset too once they reach ubiquity like fossil fuels.

In the U.S., which is among the largest oil producer as of recent years, the fossil fuel industry is heavily subsidized.[1]
