the state this innovation green, the green revolution global. so listen to a whole lot of climate problems. if the care is subscribe to those channels, we've got every friday. subscribe to plan. it's a the being a climate journalist is level or loves, but this. okay, let's do it. and do this for you. i think that's beyond 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 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 of all 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 god, it's mine is one degrees celsius outside and the water is only lights, 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 guess, right, the river plays a key role in this story. the magic is happening in the local energy provider is producing, heading 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 other thing that i'm referencing and you only have us on the 5th of the total of 2 of them. and then you may have thought of the some of the data from the shop on the 5th outside. ok. and then, but one of them got in the succeeding context of nashik to, to college inclement for them. it's amazing for them on diet, somebody or step to name, but that doesn't. this one looks a lot. so this deafening done is in fact the heat pump 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 graphs as this kind of output. 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 lower 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 at, 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, 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 moving after world war 2, bringing widespread unexcused 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 this is pamela tenants. 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 the station will probably be shut down by 2033. and one of one of my thoughts is closer to one of the forensic tullison policies. the mid to them also suffer them from. those are fed, another city of my, you know, seeing in the next me, i'm very soon as energy efficient and sustainable. every of the 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. 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 fall and with 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 m b. d. but now i mentioned one of them there with ryan, with a major city, so they're wanting to cover that tie he to month, including industrial tons such as the ss, or could extra funds the rhine will useful to meet 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 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 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 are still in each but installations have started to pick up. a role model is the swedish 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 temperature is 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 to the shoes because it's pretty small to be used in almost any residential building like this one by 20. so the heat pumps 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, particularly in 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 of self and loves it right now in 2024 heat pumps can cost to, to full time small the natural gas boilers. 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 cost cost is when prices became unpredictable and fall the tile. on average, of course, your electricity was around $33.00 times more expensive in gas. so you can see if you're having especially 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 price crosses electricity was 5 times more expensive and gas. so you can see that that would really struggle to be saving some money. so if heat pumps almost sustainable, and it cannot make any viable defense highly on your government's energy policies, whether they favor cheap, green electricity over fossil fuels in man,

i'm the prospect of high to texas local climate targets and states subsidies for the construction of the problem with the size of and the switch to read, the heating that target is to provide almost 100 percent clean heat by 2030 refund will cover all of that would be one important component to eventually shut down the dirty cold power plant behind me in the near future, no matter of smaller scale, deep 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 put into showing that i can say i can't enjoy uh, heat fall is 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 of it all. all right. i made it to the
