Humanity (especially the governments of the world) has had time to change the use of fossil fuels. We have had a lot of time to look for alternatives and the ability to make them come true. Now the world, especially Europe, is under the tyranny of Putin and his huge oil and gas reserves. I would not be surprised if Putin's government accepted Bitcoin, for those who do not know, Europe pays 700 million Euros to Russia every day for gas and oil, and Putin wants to continue receiving that money, in Euros, Dollars or Bitcoin.
