Global warming is not about producing more energy, it’s about burning fossil fuels instead of clean energy (renewables, nuclear…) and about wasting energy.
But it’s not as easy, technically everytime you use your car you become “part of the problem”, or everytime you buy some useless single-use crap from temu, but I think it’s unfair to blame yourself for it. The system allows and encourages wastes and “problematic behaviour” because it’s either more profitable (see bigger cars in the US) or changing is more difficult and politically inconvenient.
I used modern gnome and I seriously don’t understand how it’s “more modern”, most changes feel a downgrade, I cannot divide apps by categories anymore, I only have a big menu that takes all my screen and shows me like 15 apps at a time, unlike “traditional” desktop apps I can control with Alt+Some keys I have the same toolbar filled with burger menus and icons with no text so difficult to use, gnome file manager is objectively inferior in features to Nemo, and don’t get me started on the desktop, when you click an application icon on the application bar it doesn’t even minimize like on every other desktop interface.
Either ubuntu ships a broken version of gnome or it just sucks, and there are also all kind of management issues that make development very inefficient.
