It wasn’t clear (at least for me) why gas has such an impact on the economy as a whole because many articles concentrate the debate on the private households heating only.

But currently, most of the gas is used in the industrial sector (chemicals, power supply, food preparation), also for electricity generation and for producing materials such as ammonia, plastics, methanol and hydrogen.
