Reality vs theory - "Screw it, why bother?" is the real-world top result. Do you see a concerted international effort to regulate away our dependence on fossil fuels? Because right now, the only concerted international effort I see is OPEC dumping oil on the market to underprice new competitors out of existence.
The "options" of which you speak are mostly what wealthy industrial nations impose on poor and underdeveloped countries. International politics and economics is a seriously hardball game. Sure, it could be better, but it won't be.
"Lack of political will" ignores the complexity of the situation, when actors are motivated to cheat or exclude themselves from consensus. It's not a far cry from saying we lack the political will to end all wars.
I'm an engineer. Rather than complaining about what I wish I could do if I only had the resources, I think about what I can do with the resources that I have. In the case of something like fossil fuel, I think about how to create a less expensive alternative. Truly cheap wind/solar would put oil out of business by default.
This is also why I idolize Elon Musk. Rather than complaining about the lack of political will on the part of governments to get humanity off Earth permanently and stop using fossil fuel altogether, he created SpaceX and Tesla, and is making it profitable to solve humanity's deepest problems.
