Here is a post from the International Energy Agency (IEA). Energy Subsidies,with an interactive graph and data in an Excel spreadsheet. The data is in Millions of USD and you’ll see that the subsidies aren’t insignificant.
The value of global fossil-fuel consumption subsidies in 2015 is estimated at around USD 320 billion, much lower than the estimate for 2014, which was close to USD 500 billion.
Interestingly, the U.S. isn’t in the chart or Excel file and so the global subsidies likely don’t include the U.S. Still, the data is useful.
