Coal is by far the dirtiest fossil fuel. But could it have a shot at redemption… through geothermal energy?

The box! The BOX!
Excellent, thank you
It just occurred to me how dumb the AI's chosen source of thermal energy is in The Matrix. So it seems much more plausible now…
I imagine this would be particularly valuable in places like West Virginia, with an economy very strongly dependent on coal mining. It'll be an important task to bring new jobs in renewable energy to places that might be resistant to change, but employing the skills workers already have would be an easy part of that.
lets use our mistake to fix our mistake.
The distribution network seems like it could relatively easily switch between competing heat sources. Top down policies even ones that make sense scare people especially americans.
geothermal finally receiving the attention it deserves. it has so much potential that it makes so disappointed to see how disregarded it is by policymakers, and even environmentalists ourselves. using old coal mines and repurposing them for geothermal is a bit of a no brainer to me, especially when it's basically a free and 'seamless' transition from fossil fuels to renewables, since it utilizes the same expertise and strategy. I honestly view geothermal as a better source over both nuclear and hydro power, if policymakers actually had the gall to embrace it
Yeah nuclear and geothermal energy will be key in winter peaking grids.
Welp, I've found my favorite quote in this.
"until you reach the asthenosphere, or the upper mantle of the Earth's interior, where the line goes wheeee!"
Why is EVERY BLOODY CLIP OR PHOTO of a nuke plant showing one of those roughly hyperboloid cooling towers? Lots of coal plants use them too, and my local nuke plant is cooled by seawater and doesn’t need one. The nuke plant near where I grew up was built near a small but adequate river that was dammed to create a reservoir of cooling water for it, and doesn’t have a cooling tower either.
Of course I know why: The Simpsons has it that way and of course they’re completely accurate. (Everything radioactive glows as if coated in that green phosphor, even with no green phosphor, by the way.)
This is why the netherlands builds dikes to make polders, as its warmer below sealevel
I thought this would be a debunking video. I love that it wasn't.
Frakking but for geothermal.. that's.. well, more earthquakes is not exactly a good thing.
So… unless this is a “pave the way to be replaced with solar, wind or nuclear energy” video, it is probably just a long winded lie
Stop adding those annoying fake sounds!
THORIUM guys!!!
It has literally zero drawbacks and a plethora of benefits
Undoubtedly the funniest, most informative and inspirational videos
There's plenty of money they just piss it off on war
DrSimonClark! A bit off topic, but I wanted to tell you that your video about e-bikes really got me thinking about how I could use one in my life, and a few weeks later, I bought one 😀 I hope to use it to ride to work and get groceries and feel good about not using my car. Thanks for all the content!
Great video man
This Video was a nice throwback to my project paper that I wrote for my university
AMAZING INFO, RESEARCH AND SKETCH COMMIC . Love it 🎉
According to ur gov info my rough calculation Sugests.
0.03% pick up rate would make coal geo thermal worth wile , Over a medium density area.
Or every new build estate of a decent size.
Plus new build’s ,(incl flats), could be legislated, kick-starter’s ,to get to the infrastructure to connect minimum number homes.
Bonus incentive, subscription might not have to be completely tied to amount of energy u use or atall for first ten years . Hence cosier home’s, unless full utilisation is adopted.
Rather than bit cooler than u would like .
16:58 has me crying!!!! that ssht was so funny!!
I think China said , they aiming to go neutral or cut coal out by 2060.
But not quite yet reached peak coal burning . Be soon. Them soposidly faze it out before 2060
I wonder solar panel waste heat stands in terms of usability. It is not something I know a lot about and haven't seen too many people talk about.
I’m sure this video is enlightening but it’s boring 😐
Not my ass surprised to hear Poland mentioned as a shining example of district heating – even though im literslly sitting next to a district heathing unit and even looking dorectly at it x.x Or rather, looking at my cat, sleeping on their heater hammock, but the point still stands. I really shouldn't have been this surprised by this xd I guess the naming being this far off from Polish name for it could be the reason, cause here we call it centralne ogrzewanie [meaning "central heating"] or ogrzewanie miejskie [meaning "city's utilities", as in provided by the city and not produced individually in the household].
They are way way waaaaay cheaper than any other form of heating, that one I can confirm. That's why a flat having district heating is a strong selling point when it comes to renting flats or rooms, any other options means paying a lot more monthly in utilities.
Really nice video, Simon! My only qualm is that you didn't include the north of Scotland as the north north in the UK. Don't forget about us! : )
As a Dane watching this, I was thinking it all sounded very familiar. Then you mentioned Denmark is 65% district heating and I was like: Ooohhh!!
Fracking also introduces a huge amount of nasty chemicals into aquifers and the whole region in general. So yea, using clean water for geothermal has far less negative environmental impact than fracking.
i once moved onto a new housing estate with district heating…the house was delightfully snug….however this concept proved to be too much for the savages who moved into the housing estate, and after a few years it had to be dismantled…
Geothermal, Hydropower and Nuclear for the baseload!
With a closed loop where the working fluid boils at the heat source, gravity could provide the transportation of the working fluid, and thereby heat, when the heat source is far below the point of utilization of the heat if the working fluid travels up as a gas, and back down as a liquid.
It would even be possible to extract a small amount of power with turbines in the working fluid lines in the mines, if the working fluid is reheated by additional heat exchangers afterwards.
I suspect somewhat obvious and viable energy solutions that we have known about for a long time doesn't get the attention they should in part because they've since long, and over and over, been dismissed after being compared to keep using cheap fossil fuels, that we're used to, doesn't require much investment for a given capacity of on demand power/heat generation, and also has the advantage of highly developed systems for everything from extraction and distribution and utilization, and other aspects.
The graph of temperature to depth shows that the deeper you go the temperature rises slower and slower….
I think it can be a mistake…
Interesrting stuff but it could have all been said in half the time. We all have busy lives.
30kw is not a good estimate for a uk home heating need. a typical gas boiler has a tiny duty cycle. when fitting a HP proper heat calculations point to heat needs for average homes of ~5kw at -2 C . so your example would be more like 1.8MW/km2, i think, and as new builds this would be lower still. but heating networks make allot of sense for new build estates when install costs of the network would be much cheaper. interesting vid thanks
So the heat is there forever and we could never use it up at all 😅… you know what happens next right. 'Scientists are amazed to discover that the geothermal energy. Was not infinite 😮' but nobody cares because the sea is an acidic mess and only a tiny amount of insects are left (somehow the pesticides didn't just work on the crop eating insects, who could have known though). Don't worry though, stay positive, enjoy having a slightly newer car than your neighbours, sarcasm, sarcasm 😢
Nuclear waste is a myth because it can be recycled and used to make more fuel or nuclear batteries or used for cancer treatments and a billion other beneficial uses
Geothermal: its like work from home for nuclear.
Thanks again for the videos
I dunno if this was intentional foreshadowing or something, but the minecraft visuals are really funny given the fact that coal used to be the default minecraft fuel source. But now after the game has evolved, Lava is the most powerful and effective way of fueling furnaces instead
Oh god i was listening to this podcast style and as soon as i heard "Look at this graph" i had to check and you delivered
Everyone thinks the energy transition will lead to net zero and the warming will stop. But the oceans will continue to warm and the ice sheets will continue to melt, ice reflectivity will continue to decrease and feedback processes will keep it going.Veteran climate scientist Jim Hansen has usually been right, and unfortunately his team are now saying that with a doubling of CO2 we’re in for 10°C rise in 400 years. Even 6°C is Armageddon. And with methane and nitrous oxide and the F gases were already at about doubling of CO2 equivalent. Marine cloud brightening could cause another ice age if done to extreme, but it’s not allowed because there’s been too much political capital spent on net zero. Good luck young people. 🙁
Super interesting video mate. Loved it!
I always thought it'd be neat to have glycol loops in buildings, kinda like they used to do with radiators. But have it be bidirectional. Your refrigerator can pull from the "cool" side and dump it's heat into the "hot" side, while your heater can do the opposite.
Funny, how nobody takes into account, that whenever half of the earth has night, the other half has day and that whenever there is no wind in one spot, there is plenty of it in another spot, like in a neighbor country. Why on earth does every country constantly pretend, that it must generate 100% of it's needed energy itself, when already today some countries import up to 20% of their total energy needs from neighbors and at the same time export that much when they have way more energy available than needed? HVDC networks only have an energy loss of 3.5% per 1000 km (620 miles) and we have already built HVDC from Norway all the way down to Morocco. Sure, importing energy costs money but building power plants and operating them costs money as well and all import costs are partly compensated by export income whenever you are the windy spot and everyone else needs to purchase your energy. People just must stop thinking so locally. We have global markets and we also have a global energy market for decades already and it keeps growing and growing. There are locations at the African Atlantic coast that don't even know what a wind calm is because people there have never experienced that phenomena in their entire life. If you would build huge off-shore wind parks there, you could easily transport the energy to UK using HVDC and guess what, the energy would even be cheaper than producing it in UK, as producing energy in Africa is maybe 10% the price, so even with HVDC transport costs, you'd still save money.
