Sorry to be so negative, but people being angry, still requires them to be organized and work on overthrowing Putin. Unfortunately Putin killed all opposition leaders.
This makes Putin falling more likely, but it needs a spark of hope and that will be hard to find in Russia.
This is a lot more complicated. The jobs in the oil and gas industry are well paid and will be hard to replace for a number of communities. A refinery creates a lot of union jobs, with great pay for example. Combustion engines also provide more jobs then electric drive trains. So fewer jobs in the car industry. Also companies like Rolls Royce. It is hard to find a replacement for jet engines, which can do something similar. Airbus in general is a big employer in the UK, especially with the entire supply chain.
That is just some stuff coming to mind. It really is not that simple. Obviously there are new green jobs created, but those jobs are not necessarily in the same places, as the old fossil fuel ones.
