to assign it a is up next with a look at how heat pumps a revolution rising. the way we keep and cool on houses and cities, i'm any troopers mckinnon. i'll see you at the top of the next down the the race. as long as the gun later, when we look back, we recognized at all, that's the moment when everything change. it's all about dominance. in the age of artificial intelligence, 5, you see, i mean, it was in china the us. oh europe. to control the technology

that will shape the future of humanity, the small, it's new world, the a i race start smaller 16 on dw, the being a climate journalist is level all of but this. okay, let's do it. and do this for you. i think that to be on the next level, i want to show you how tweet 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 done and why aren't they 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 binding 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 degree celsius outside and the water is only like the wilma. 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 provider is producing headed curiousity. 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, mtv. 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 thing that i'm definitely thinking you own this of us on this is of the total of 2 of them. and then you may have thought of the some of the data from the shipment home from the states outside

. ok. and then, but one of them got in the succeeding context of nashik truth to college in oklahoma to them it's amazing for them on diets under the doorsteps. the name, but that doesn't. this one looks a lot. so this deafening done is in fact the heat for river by pushing through 800 meters of rid of all type of 2nd. it can provide heat for $3500.00 households audio rooms. okay, wait a 2nd. let's take a separate. 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 gus as this kind of upward. extremely low temperature is the gas expense. and electric pump then compresses its gas. this generates heat,

it's a bit like with the bicycle pump, the longer your pump, so the higher the pressure, the whole tide gets, try it out. the heat of gas is used to low 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 to the principal 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, kind of a design, the 1st commercially successful ammonia up stokes and 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 hauled and submitted to problems in the printing industry, only day to the heat pump. and 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 raise of the entire house. with western economies booming after world war 2, bringing widespread next week's vacation 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 huge storage

from where the distributed over the entire almost 10 in the got. so then so it's a policy and cubic meter bustle. and so it's a 1000000 in this of the safety of often available on the silver fillings 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 power station will probably be shut down by 2033. and the volume of one of my thoughts is closer to one in the forensic tullison policy by the method and also suffer them forms because often the other cinema. yeah, fucked up. seen in the next to me and the soon as energy efficient and sustainable . real, a heat pump is taking each 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. so is this beneficial to a point and put you on that you will have need be um, an access ecological effect that you might want to avoid? this is father and all the scientist at germany's on, with the 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 $110000.00. it's of a degree according to m, v. v. but now i mentioned one of them there with ryan, with a major city. so there was one thing to cover that tie he to month, including industrial tons such as the ss, or could extra funds. the rhine will useful to mid the might use water for, for heat pumps, for the processes. and suddenly you get to, you get an issue with another issue, all the refrigerants that can be terrible greenhouse gases. what's your video and ask us 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 to generate to cheat is distributed by district heating over and microsoft and 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 have to have a nice but installations have started to pick up a role model is this, we just capital style calling way about 90000 departments are heated from wastewater just as the norwegian city of drummond provides most of the heat for it's 65000 residents with he's from its cold sea 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 needed. the phones can extract energy from almost any c. yeah, way for the sea and even from the ground. is it only 2 issues because it's pretty small to be used in almost any residential building like this one by 2030 heat

pumps could save as many emissions as all the costs and you produce per 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 non profit 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 for the tile, on average, of course, your electricity was around $33.00 times more expensive in gas. so you can see if you having an official heat pump getting a 300 percent full 100 percent efficiency, you might be saving some money back in the u. k, where ours is before the press costs electricity was 5 times more expensive and gas . so you can see that, that you would really struggle to be saving some money. so if heat pumps almost sustainable ends, because on the kelly viable defense, highly on your government's energy policies, whether they favor cheap, clean electricity over fossil fuels in man i'm the prospect of high to texas local excitement targets and states subsidies for the construction of the plan with the size, if in the switch to rip a heating that target is to provide almost 100 percent clean heat by 2030,

we funds 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 the problems 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, i'm sorry i can't enjoy uh, heat phones popular where you live. let us know and 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 respect. it's all about what can we have and texting?
