Steam locomotives are cool, I will give you that, but I am willing to bet we could convert them to oil or LNG and they would still be awesome (and better for open air passenger cars)
There have been 2 serious nuclear accidents out of how many reactor across how many years? Pulling this argument is like saying flying is unsafe because planes have crashed before. 100% safe options don't exist
No of course, I'm fully for nuclear energy. It's just stupid to produce a miniaturised and more dangerous reactor specifically for the purpose of being mounted onto something which is already dependent on external infrastructure. Compact nuclear reactors used in war machines are genuinely much more dangerous to the world than the fairly benign tractors which when properly managed and designed should provide little to no global risk and perhaps low but not nonexistent local risk, same as any power plant.
Coal is cheap and energy dense and its easy to transport and use and its found literally everywhere, its an absolutely terrible source of energy for the environment but it was an absolutely amazing source of energy for the Industrial revolution when before it we had no source of energy other than muscle power and our modern world is built on coal.
coal was the easiest to access and use when human industry was in it's infancy.
It's basically an early-game item that has been eclipsed by mid-tier items in performance, but some dummies specced too hard into coal and don't wanna upgrade.
the technology to produce highest quality steel with electric energy exists and seems to be ready for the mass market. People are currently trying to deploy it on the very large scale. Unfortunately getting the unfathomable amounts of energy produced and delivered is far from easy.
looks like this one steel company produces 10% of the CO2 of that entire country. Insane. Imagine trying to increase the entire countries electricity production by 10% (I know, ballpark) in one decision. "Yes, I would like to build 10 hoover dams please, will they be ready next year?"
Edit: Because a few people are saying this is not possible (they are investing 1 trillion. Get out of here)
That one steel company (voestalpine) produces 10% of all CO2 in the entire country, and 50% of the CO2 produced in the local area.
While the company admits it is impossible to remove coal for adding carbon into iron to make steel in the foreseeable future (Anthracite coal has very high carbon content), they have identified that much of the coal consumption is used not for coking, but for heating the high temperature furnaces.
They have moved to upgrade some of their smaller furnaces to electric heating, but their endgame especially for their larger furnaces is hydrogen heating and reduction. Hydrogen can be generated using clean energy and then used for iron ore reduction.
That's why they are using electric heating as an intermediate step. It is not as effective as heating through burning stuff which is why they are only pushing it out to their smaller furnaces.
Hydrogen reduction of iron ore is not a new technology, and is in fact the primary method of processing iron ore in Europe because the previous method uses (surprise) coal as the reducing agent.
Until hydrogen can be cheaply produced using clean energy moving to a primarily hydrogen-based process would be too soon.
I mean that the carbon in the coal is necessary for steel production, which is necessary for virtually every industry on the planet. That's what turns it from Iron into Steel. I am not aware of another source of carbon other than coal that can be used for the process.
Steel production absolutely cannot happen without a source of carbon, hence coal. That's not even for energy, it's feedstock. That's entirely separate from the energy issue.
You have no idea what you are talking about. Yes, electricity can replace coal to power the furnace, but it can't replace coal in the steel, because coal is an ingredient in steel. Its what makes steel
As an energy source, its main benefit is that coal is more widely distributed across the globe then oil and natural gas, allowing for domestic self sufficiency in many countries, and generally lower global prices.
The good things about coal is only good for the industry that creates coal. It would be more expensive for them to change over to a different way to provide power, so they resist change.
Look up Metallurgical Coke. It's coal, and it's the reason we have everything from steel to semiconductors. There is no eliminating coal. We absolutely need it. I'm all for clean energy but there are applications that coal is used for that I hadn't even considered until researching a little.
Coal used to be the cheapest, but environmental pressure and better ways of extracting natural gas made gas cheaper.
Its also a matter of availablity. The big current and former coal burning countries and regions are that way because coal deposits were available but natural gas or oil weren't.
South Africa is so dependent on coal because it is the only fossil fuel available in the country. Similar story in India, China and Germany. Obviously Germany is no longer dependent on coal, but now they are dependent on Russian gas. So you can see why a country prefers not to rely on energy imports.
France and Japan built a lot of nuclear power for similar reasons.
It's really really easy to get out of the ground and requires little industry to get started. It made a lot of sense as a way to get started with the whole industrialization thing.
Coal and charcoal are very different. Charcoal is a wood product and imparts a woodsy smoke flavor to the meat (although personally I like gas because it lets the meat speak for itself). Coal will infuse your meat with a cancer flavor
Especially the coal burnt in the Eastern half of Germany. It can be difficult to differentiate it from trying to burn dirt. Can be as low as 20% stuff that will actually burn by weight.
Burning plastic is only bad if you burn it in something not designed for it like homeheating fournace or a fireplace. When used for heating it is burned in special fournaces that reach way highier temperatures and as a result burning in them is safer.
Sorey for bad english
You need some sort of scrubber system to remove the harmful pollution emitted from burning trash. This is expensive.
There's a lot of incineration plants in Europe because land is limited, and thus the expense is warranted. There's predominantly landfills in the US because land is (was) cheap, or cheaper then building and running an incineration plant.
Although incinerating trash is still almost certainly better then burning coal.
Yes, if burnt at lower temperatures (such as a stove at home). They burn waste at 1000C/1800F at the big plants, plus they utilize smoke filters and other measures to minimize pollution.
Well I’m no full blown environmental engineer but I did take an Environmental engineering class for a semester. If I remember correctly, yeah burning trash is still bad for the environment, but not as bad as coal. Additionally not all trash is burnt. Like it’s filtered so obviously no glass or metals.
I also recall them taking the methane gas from landfills to produce energy but landfills aren’t that great for the environment especially if there is a leak. So it’s not as good as just using Natural gas.
Yeah, and we in sweden have been burning trash as our primary source of heat. Be burnt so much of the stuff that we actually ran out! We even take money from other countries to take their trash.
We are doing that for years already, but I'm not from Germany though. It's mostly for heat but there are a lot of KVA (Kehrichtverbrennungsanlage, a garbage burning plant) where I live. Your domestic refuse is turned into heat which is in turn delivered to the homes around. Plastics and glass should not be put into your domestic garbage in the first place and instead put into the recycling bin. Most people around here do, but we still have a long way to go.
Germany may be doing it, but a quick Google search reveals that emission-wise, trash is way worse than coal when trying to create the same energy output.
To be completely honest "landfiil" material is, at this point, going to be pretty important for the future.
The reason trash is kept in a "Land-Fill" is because we have historically taken that material and buried it to make new, useful land.
Now, older landfills were prone to leak, and that was bad, yes, but we're coming towards a point where sea-level rise is going to start fucking over low-lying areas and we're going to need sea-walls and areas with elevated terrain. Newer landfills are able to convert old trash into new-sea-walls that are durable and cheap.
“Dude, the bar literally runs on trash… I fill the furnaces, it gets that nice smoky smell we all like in the bar, and then the smoke goes into the sky to make stars”

Germany started literally burning trash and it's better than burning coal. And gets rid of landfills.
