I want to write a novel that takes place sometime in the latter half of this century (let's say 2075), where the premise is that we've more or less achieved what could be described as a Solarpunk society globally, albeit not a perfect utopia. I am just an amateur, so don't hold your breath for the next literary masterpiece, but I am hoping that, if finished, it could at least inspire some people to envisage a better future. The novel itself will only use this as the setting, as a contrast to the often bleak and dystopian visions of the future - the plot will not be related to how this was achieved.

I am currently looking for inspiration for the world-building. What have happened between now and then on a big scale, particularly in terms of geopolitics? How did the tensions of today resolve so that we eventually landed in a Solarpunk society? I am happy to read both critical analyses of probably futures as well as speculative fiction on what could become, but that still remains rooted in the realm of the possible. The world should be mostly stable at the point of the novel, but many turbulent things could've happened on the way there.

A few examples of things I am looking for:

• Which regions/peoples gained independence? Are The Republic of Ireland and Northern Ireland reunited, is Scotland independent from the UK, is Catalonia a sovereign state? Other examples outside of Europe?
• How have e.g. the African Union and/or the East African Federation progressed, and what role do the play on the global scene? What about other would-be superpowers?
• How did what today looks like an uncrossable divide between the left and right in the United States resolve? Was there ever a new civil war? What did that look like? Are they still united? Any new states?
• Has the United Nations undergone any changes to become a more effective organization?

Have you read or seen anything like this that you could share? Articles, books, movies, TV-shows etc.? Do you have any thoughts of your own you would like to share?
