Don't forget industrial heat. If we had infinite electricity for free everywhere there would still be fossil fuels burned for industrial heat. We need more technology to finish it like plasma torches.
No need to despair, the technology is being actively developed and a lot of the sub 600 Celsius temps have an electric solution now.
Depends on where you live and your situation. You either limit your personal CO2 or the society's CO2 or even both. Most of my suggestions will make or save you money over time.
For personal you could do these, most of these will pay themselves back within 10 years in savings.
Swap gas stove for induction stove
Swap a gas boiler to heat pump + electric boiler
Buy solar panels for the roof and/or battery
Heat pump for domestic heating for colder regions.
Home insulation such as triple glass windows
For hot regions getting an awning for the windows facing the sun goes a long way.
Selling car to buy EV (CO2 neutral at 1 year, less CO2 after that)
Buying an E-bike if you have short trips and would like to bike more (CO2 negative almost instantly if you prevent car trips)
Otherwise if you don't feel like any of those investing in solar companies or battery production companies will make it easier for them to finance expansions to their operations and maybe even make you some money along the way.
If you live in the UK or applicable countries getting in on Octopus energy co-op energy production is a good way to invest the money and reduce CO2 at the same time.
Don't forget that an easy way to limit your carbon footprint is free. Notably plastics, aluminum, steel, other metals, concrete and beef.
To limit society's footprint you can show up to city Council meetings and advocate for bike paths and public transport which really goes a long way. Showing up with a couple of buddies, making them talk and buying beer for them after in one of the most cost effective ways to stop climate change. Often city council members just need some people to back them up when proposing the CO2 negative urban planning improvements.
Stopping climate change is all about taking small steps towards the solution, asking this question on lemmy is a great start.
Make a text adventure game that runs in the console.
Tic tac toe in the console.
Then if you want to go for a GUI web app with react use "dotnet new react" and create a to-do list with a client/server setup.
If you want to learn to make games you could make a tic tac toe again but with a GUI in Godot.
Once that's done make tetris.
You research what you need right before you need it and use it immediately so it sticks better. You'll need to get comfy with typing systems and I recommend using an IDE like Rider or Visual Studio to program it since they help out a lot.
I use vim mode everywhere I can and vim in the console, it took a bit of effort to learn but it was fun and satisfying. Highly recommend, I'm a vim user now for 7 years.
IUD is not sterilisation, it's a reversible procedure and Denmark has historically done much worse. Currently the relations have been good and the axe has been buried so I see it as a win for Greenland to stay as a part of Denmark.
I think all countries should be allowed to go for independence if they choose to but I'd really suggest Greenland to reconsider. They get a massive amount of expenses sponsored by Denmark compared to how much they pay. It's essentially like having a sugar daddy.
Things are moving fast! Can't wait for them to figure out clinker for cement.
