Here is a news article from the US, about the subsidies that oil and gas companies receive.  The UK Government also provides subsidies to oil and gas companies.  An example of this, is the reduction in corporation tax for the North Sea oil and gas operators.  As the video infers, this is because of the level of political donations received by the politicians.  Except in the UK, it is Party political donations that are the problem along with lobbyists.  And a great number of the British public are not aware of these subsidies, and blame their high energy bills on subsidies for renewable technology.  Renewable technology receives a fraction of the subsidies the oil and gas companies receive.  And nowhere near the £50 billion the nuclear industry has received so far.  And it will cost more than £50 billion for the clean-up of the decommissioned nuclear plants.
