These subsidies are mostly implicit. Particularly in countries like the US, Canada etc. Implicit are basically environmental costs. The only countries that government actually is subsidizing growth to any extent are countries like Saudia Arabia, Iran, Russia. To a lesser extent you have Western nations like Germany and the UK that are subsisting energy to your house so you don't pay so much.

In other words the biggest cost or implicit subsidies as they call it is not subsidies to companies but the environmental costs us consumers do not pay to use energy.
