The World's attention has been on COP28 that finished this week. For the first time this summit has made a clear commitment to transition away from fossil fuels, and the ambition remains to limit the global warming to 1.5 degrees. This means that we have to significantly accelerate the rate of building non-hydrocarbon based energy production and other relevant infrastructure. But there is still no discussion at this global level as to how were actually going to build these greener energy resources - where are the resources, particularly metals, going to come from? There is still the assumption that the metals are going to be available when we need them, but that is not necessarily the case. Urgent action is needed to ensure mining can keep up with the rapidly increasing demand.

❤. The second law of thermodynamics provided by far the best way to get out of the energy production needed. The differential of temperature,( heat pumps) no needs for electric system.😊

As long as I can figure out, they don't worry about Earth.

They do care, but only when they can sell it.

There are many sources already known but has been waiting for demand to increase, I live alongside one such mine, a tungsten mine. It's ready to go and could be producing within 6 months. Mining has been necessary for the progress on man and old mines can be covered over and re-wilded, some of the old mines near me has already been turned back to nature. There are plenty of resources in the world for instance Lithium, Lithium salt is in every cup of sea water and the rock form has massive deposits in Australia and USA, Australia already mines 40% of the worlds Lithium and it's much more environmentally friendly extraction than Oil Tar Sands which destroys thousands of sq. miles of wilderness

Even without sea based lithium there is enough lithium on land for 3 billion cars, which is plenty. Trucks, home and grid storage can use sodium batteries which are heavier but sodium is more plentiful. Cargo ships can use ammonia made from green hydrogen and nitrogen. Planes and passenger ships can use synthetic liquid hydrocarbon fuels.

It can change look at the UK, it used to be coal driven now less than 2% of energy comes from coal and oil. Even Coal Australia is almost green, it can be done, it just depends on the time scale, some countries are doing it faster than other. This year China has built twice as much solar as the rest of the world put together. Businesses are realising you have to pay for coal and oil but the wind, tides and sunshine is free, so they can see the potential and investing fast. All the metals are available and which ever way you cut it, all wealth comes from the ground. Mining is huge now and it will expand to cover any slight increase in demand

How much coal has China built in the last decade compared to solar?

It's interesting how South African you sound - not Dutch or Scandinavian - I spent some times with Finnish girls and they did not have that accent either (my accent is Cleveland Ohio so ...) I really like the practical technical applicational (not a word) way about these video's - there's a whole 'world' underneath our feet and keeping us alive as I type on plastic made of oil and these video's remind us of that and they are very good graphics as well

Hi I'm Al, I stumbled acrross your vids and I enjoy your productions, you have an engaging style with well thought out and delivered content. I understand the work and effort that goes into these videos. I thought I might offer some unsolicited editing / shooting advice, which, of course, you're free to totally ignore.... :) After listening to the audio, I went looking through your different vids to see if I could find your setup, and I suspect you're using a headphone and intergrated boom mic for your voice overs. If so, it would be worth investing in a studio condensor mic ( buy it used, you'll save a truckload cuz all production gear is WAY overpriced :) ) with a pop filter (quite important for you, no offence intended) to soften your S's. Maybe put a little 3 sided wall of sound foam around it to stop reverb, particularly if your editing in that little office, it's a Location Sound Engineers nightmare....... :). Your field recording in windy conditions could use a bigger dead kitten on your lav to cut wind noise, which is apparent in some outdoor scenes. If you're concerned with the lav looking unsightly with a bigger dead kitten, hook the mic under your shirt to your bra, hidden between your cleaverage to stop any unsightly bulge showing externaly. Make sure the dead kitten stays on, as this will stop any rustle caused by your shirt rubbing on the mic. Thin cotton shirts have very minimal effect on sound degredation. Now, if it's too cold to be wearing a simple Tee shirt and hiding a dead kitten is awkward, it may pay to consider using a camera mounted shotgun mic, paricularly something that has a >3M range. Check out the Rode NTG series. Be aware that most shotgun mics (and indeed, most Pro mics) require Phantom 48V to power them. The Rode NTG 4+ is an exception. ( audio can be a long slippery greased pane of glass that one is forever trying to scale.....) Another thing you may be able to improve, is your video dead space. In your case, the dead space is often where you start / stop talking and cut from / to a studio voice over and assoiated scene. These dead spaces are often a second or more. One of many strategies to mitigate this is to do do the cut immediatly (say 2 frames) after you finish the last word, insert your new clip, then do a short simple fade of about 15 frames (+ / - ) each side, between the two. For your style of production, I think this would work well and is a nice simple starting point. ( I have seen this in one of your vids, but the timing is still a little off, it may be in more ) For your talking head scenes in the office, 3 points; 1. Fill the frame with your upper bust [as in the Bust of a statue, not the top of your breasts..... :) ] more to eliminate background clutter. It looks as though you may be using a wide angle. If possable, try a 35 or 50mm in that space, or simply move your camera closer. 2. Your camera is looking up at you, a big "no no". Raise your camera to eye level or marginally, but only marginally, higher. [Can be on desk, books, desk + books, tripod, it doesn't matter ] 3. Because of the huge amount of light poring in the window, shift the camera toward the window ( if the window glass is on the 12 and 6 o'clock plane looking out, 3 o'clock is outside and 9 o'clock is inside) so it sits on the 4:30 position, then when speaking to the camera, look into the centre of the lens. This will light your face more evenly using available light. Because you don't have a make up department working for you, make sure you stop down (apeture, T stop, depending on lens) so's not to overexpose your skin, this way you'll take the 'shine' ( This is known as 'Blowing out the highlights' ) off your skin. For your camera work, the pans, and pan tilt combo's are very nicely done, albeit sometimes a little quick, the general rule is to pan no faster than a full image width every six / seven seconds. I've hung out with a bit of mineralisation and It seems colour is quite accurate, very important for your subject, however, you're often overexposed. To mitigate this; 1. Use an ND filter, say an ND 8 or ND16 ( Try not to use anything other than Optical Glass ND's as colour cast can be an issue), this way the apeture (T stop) can be dropped, keeping everything correctly exposed. 2. Expose only for the skin tones, because when speaking to the camera, you're the point of importance. 3. If space allows, turn so the sun is on one of your shoulders. [ Unbeknown to most amateur Doco / Film makers / You Tubers, the sun was invented to enable good natural lighting for the professional production of the aforementioned activities........ it also gives what is known as Golden and Blue Hour at both ends of the day :) ] If you're looking for a highly efficient and proffessional editing suite you can grow into, I'd suggest Blackmagic Davinci Resolve Studio, it's a lifetime licence, not a subscription model. You could start with the free version, [ Davinci Resolve] it has a few limitations compared to Studio, but at this stage, that won't affect you. Keep up the good work and good luck. Cheers. Al.

I like these videos a lot. There will never be a solar powered freighter or a million other machines modern society depends upon even if the 20% or so of energy use that could be transitioned at enormous ecological cost were. It appears mainly to be something for investors to peddle. It isn't a realistic something, because it trades CO2 for more harmful industrial waste and can't really slow things down meaningfully even with CO2. It hasn't because it can't. They'd have to restructure society in a way that power can't allow for its survival, so it won't happen. Consumerism would have to end, for instance. Oh well.

Thanks for asking an important question, how will we extract the materials that are needed to make the transition. In the United States, we need to transition from personal ownership of vehicles to community owned fleets of shared vehicles.

"There will never be" has been spoken many times before, and then they built it. But I agree the time frame is short to stay below 1.5 degree c. To little to late.

@@johnkintree763 When we switched to driving cars rather than horses, did anyone worry about metals? We use a LOT more metals in cars than we did in horse drawn transport. The same applies to shipping when we switched from sail to fuels. All those metal ships and no one thinks twice. The biggest mineral mining on Earth, is Iron mining. It literally dwarfs every other kind of mining combined. You have never questioned any of those until now. Suddenly when fossil fuels are threatened, mining is a BIG issue. Just more desperation to stave off the enevitable switch, in everything we can, away from burning fossil fuels.

It's not ironic at all since climate is not weather.
