No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

What is the alternative? In France electric cars are expensive, and I don't see chargers around me.
To be fair, that's because the fossil fuel lobby does everything to prevent alternatives.
And it takes time for people to transition. Think about a major corporation. If they want to roll out a new piece of software, that is a three-year commitment, minimum, just to get people to spend most of their water cooler time talking about how much they hate the new software.
That is extra IT hours spent on training users over and over and over again on how to use the new software.
And after three years, somebody will step in and say, "Hey, why don't we try software Y, It's better than the software that we just rolled out", which queues a new three-year software rollout cycle.
Extrapolate that out to 8 billion human beings, well over 2 billion of which drive vehicles or utilize personal transport systems that are internal combustion engine powered, and you'll begin to get an idea of how difficult it is to transition everyone away from fossil fuels.
The good news is that it is happening, and barring major accidents, we will probably get most of the way there during our lifetimes.
Because it is somewhat competitive economically in certain use cases and a ton of existing infrastructure was already built to use various fossil fuels.
The switch to non-fossil fuels was going to take at least a generation in most developed countries since you need to build out electricity generation and storage.
We can't replace it fully.
We can replace it with cars. We can replace it with trains as well, but electrified track is more expensive than just plopping a diesel engine there and filling her up. Track for that is just steel+concrete and rocks and stuff.
We can not replace it with air planes, helicopters, rockets. At all. We could reduce air travel and stuff like fighter jets.
We can also not replace it for cargo ships. And that's pretty bad news. Luckily ships are crazy efficient, so the actual CO2 and other pollution per ton and kilometer is very very low. If you get a delivery, that delivery comes in a fossil fuel truck to your doorstep, that truck will emit more CO2 than the ship will, going either from china to Rotterdam or the US westcoast. And also global transportation is probably more than necessary.
Anyway, the big problem we can solve are cars and planes.
There are also a bunch of chemical and industrial processes that need coal. Fertilizer and steel are two big ones.
You are correct.
Agriculture, shipping, and power generation together dwarf the petroleum used by road vehicles.

besides cars mass energy storage isnt available for all countries yet, so you need a way to balance grids. green energy resources doesnt have the ramp up required when energy usage spikes(e.g people get back from work). we dont suddenly put out more sun, make faster rivers or purposely make stronger winds for power. you balance the spike with the dirtier energy. so you often run into a situation where once green, a majority of your energy can be green, but you always have to reserve space for spike usage.
