for the company, think attack had less of consequences. it will take days for production to restock again. and the damage is set to go into the hundreds of millions of dollars. all right, hans brought there will be back soon with more common meantime the we are all set and we're watching closely in to bring you the story behind the news. we're rolling about unbiased information for 3 months was caused about why does that mean? because now i'm leaving the new host to join us for an exciting exploration of everything in between

moses a video and audio production 5 d w. i hope that you will tune in the being a climate journalist. it's never all lives but this. okay, let's do it. i'm do this for you, i think that to be on the next level. i want to show you how to eat entire neighborhoods with water as cold as this is like a thousands of negroes in my legs. the answer with a heat pump, a very big one. but even the small ones are indispensable when it comes to the cabin isaac housing. these gadgets can convert seemingly infinite amounts of energy from the environment to warm our homes, even in winter. but how is that zone and why on the every way it

nothing required small energy worldwide and keeping houses. woman providing to industry, teaching accounts for half of the global energy consumption and 72 percent. while heating comes from burning fossil fuels long story short to limit global warming, we need to bring heating, emissions down. but before we get to that, we need some cold facts. i mean, really cold. okay, i'm not ready at all. oh so it's mine is one degrees celsius outside and the water is only like the warmer. thank you planted a why am i doing this? again? it's unbelievable. but in the city of month time in south west germany, this ice cold water is used to heat thousands of homes. we're going to find out how this is possible. my name is the mid sized city of about $300000.00 inhabitants. it's 6 directly on germany's biggest river. right. and you guys,

right. the river plays a key role in this story. the magic is happening in the local energy providers producing electricity. mt thing really makes a fossil fuels and cold water. until today, the region relied heavily on the most climate timing source for heating cooling. this is felix ok. he's energy manage it. energy company m b z. the magic machine we're about to show you is his baby. this single thought plant is responsible for about $6800000.00 tons of c o 2 every year. it's almost one percent of germany's annual emissions, but this is changing for the better. right now. the other thing that i'm asking you sent me in your own that of us on this is of the total of 2 of them being a mess up of the sum of the data from the shop on the 5th outside. ok. and then,

but one of them got in the succeeding outside of fashion to college. no, no gram with them. it's amazing for them. on diets under the doorsteps. the name, but that doesn't. this one looks like the last so this deafening john is in fact the heat for that by pushing to 800 meters over the water per 2nd. it can provide heat for $3500.00 households all year around. yeah. okay, wait a 2nd. let's take this septic, this is what happens in all those pipes. the what that seems co to us, but it's easily warm enough to turn a liquid refrigerant into graphs as this kind of upward. extremely low temperature is the gas expense, and electric pump then compresses this gas. this generates heat. it's

a bit like with a bicycle pump. the longer your pump, so the higher the pressure, the whole tide gets, try it out. the heat is gas is used to warm up water or f, for example. the refrigerator gives up its heat and becomes liquid again and the process can we saw. this mechanism is so efficient. you can generate 3 times as much heat with the same energy as with a gas for that. it doesn't just work with river water, you get the same effect with heat from and the ground. ideally, the electricity for the pump comes from renewable entities. but even if it comes from fossil fuels, it's still more sustainable. the principle of a heat pump isn't new at all. it's based on a concept which has existed for a very long time and on the technology, which most of us have at home a refrigerator. back in the 19th century, the demand for cooling was much higher than for heating. ice was carried from far away. if there was no possibility to keep things cool, in 1859, the frenchman fed,

you know, cause a design the 1st commercially successful ammonia absorb some cooling system. it works the same way as a heat pump. but the other way around carrying heat from inside to outside. from there, another familiar machine evolved. the air conditioning invented to solve hot and humidity problems in the printing industry. only later, the heat pump had it's big moments. the pride and joy of the man of the house is the weather control center. a center that puts you in charge of the electric heating and air conditioning, and the electronic air sales or any of the entire house. with western economies booming after world war 2, bringing widespread electrification and new life style expectations, heat pumps, fitted right in. but as most people were happy to buy and cheap or the gas for decades, it didn't really catch on until now. so now we're going to see the heat storage

from where the distributed over the entire this is pamela tenants. so then, so it's a pulsing cubic meter vasa, fitness up at the end. so it's a 1000000 in this of the safety of often available on the silver for at the moment by far, the largest proportion of this is still heated with cool. only 3 percent of the heat comes from the river, but that was soon changed as the coal fired the station will probably be shut down by 2033. and the volume of one of my daughter is closer to one and us prince to tell us in policy as a meant to them and also suffer them from for us are fed and others, you know, my, you know, seeing and the next to me and the soon as energy efficient and sustainable, really the heat pump is taking heat from the river means that the want to is being discharged 3 degrees quarter after the process with potentially negative impacts on a larger scale. luckily at the moment, most of which is obviously he to, to,

to climate change phase. this beneficial to a point and put you on that you will have need be um, an abscess ecological effect that you might want to avoid. this is probably an odd scientist, a gemini, is calling or a i. e, g, an expert for large scale heat pumps. however, due to the small quantities of water being discharged, the temperature and the river only changes by less than 110000th of a degree according to mtv. but now i mentioned one of them the river ryan with a major city. so they're wanting to cover that tie he to month, including industrial tons such as the b s, s or cook extra punch. the rhine will use ball to mid the might use water for, for heat pumps, for the processes, and suddenly you get, uh, you get an issue with another issue. all the refrigerants that can be terrible greenhouse gases, which are video and f gas. if you want to know more, there are alternatives on the market which have less global warming potential. but some of the other issues such as being easy to ignite and manufacturers tend to

produce business as usual. in my name, the generated heat is distributed by district heating over and on the grounds in germany, around 15 percent of all buildings. and though he does in this way, and most of it could be meant by large heat pumps, cutting out cold and gas. they asked of a nice but installation. so start to, to pick up a role model, is this, we just capital style call and weigh about 90000 apartments. i heated from wastewater and the norwegian city of drummond provides most of the heat for it's 65000 residents with he's permits, coats the water and communities don't even need this strategic heat pumps can be directly attached to a building or industrial side where temperatures up to 200 degrees celsius are needed. the phones can extract energy from almost any see way for the sea and even from the ground. is it only 2 issues? because it's pretty small to and be used in almost any residential building like

this one. by 2030 heat pump, this could save as many emissions as all the costs, and you have produced a year with smaller units taking a central stage, especially as heat pumps can also turn from heating into cooling mode. at a more energy efficient than classic air conditioners. but there is a catch, of course, it's the money, a particular woman, sterling of 1st heat pump, switching from a different hitching system is always going to be more expensive as we all right. now, this is really something that she's a policy expert at nonprofit regulatory assistant project. she has a heat pump itself and loves it right now in 2024. heat pumps can cause $2.00 to $4.00 times small the natural gas for this. it's a big outlay, especially for low income families. on the other hand, long term they could save you money as heat pumps need less energy. in europe, households currently save on average $900.00 per year, and in the us $300.00. but the advantage of fossil fuel heating depends highly on.

yep. energy prices is full. the recent energy price cost is when prices became unpredictable and fall. a tile on average across europe and electricity was around $33.00 times more expensive in gas. so you can see if you having an efficient heat pump getting a 300 percent full 100 percent efficiency, you might be saving some money back in the u. k. where, oh is, is before the press cost is electricity was 5 times more expensive in gas. so you can see that, that you would really struggle to be saving some money. so if heat pumps almost sustainable and be comically viable, depends highly on your government's energy policies, whether they've favor cheap, clean electricity over fossil fuels. in man, i'm the prospect of high su, texas low climate targets and states subsidies for the construction of the plans with the size. if in the switch to rip a heating that target is to provide almost 100 percent clean heat by 2030,

we probably won't cover all of that, but will be one important component to eventually shut down the dirty coal power plant behind me. in the near future, no matter of smaller scale heat pumps, almost sustainable, and can make regions more independent from fossil fuels. and they do work in winter . i hope you appreciate the effort i flip into showing that. i can say i can enjoy a heat pumps pump, you know, where you live. let us know when the comments subscribe to our channel and hit the like button. we have new videos for you every friday and i need to get out, you know, all right. i made it to the big hot dogs make a strong case against smoking in frames because health is needed.

how many platforms can you handle single tenuously without having the feeling that it's just too much you might see me how much can we do simultaneously? multitasking these, the modern because if we do too much, we get it all wrong. we mess things up, risking brain damage. so let's stop this self sabotage humans. animal of the tasking watch. now on youtube dw documentary, this shadows, these pod costs and videos shed lights on the dog is devastating. colonial har is infected by germany across and he employed the schools, tactic farms and destroy lives. what is the legacy of this wide spread races,
