What the next steps are from the side of ground invasion. And of course, perhaps the, perhaps the reason that it hasnt happened yet is because of those hostages. So no definitive answers to that question, but certainly a lot of how its raised. Well, at least, hopefully for one family today, that was the w, rebecca readers in jerusalem. Thank you very much for your reporting. As we reported earlier, how mazda is free to american hostages, the mother and daughter were among more than 200 people, abducted by a most during its terror attacks in israel. 2 weeks ago, he was President Joe Biden said hes overjoyed, and mother and daughter walked to freedom nearly 2 weeks after being taken hostage by the is for mr. Newton group him us to american citizens, held by him us since october 7th were released. These 2 americans are now safely in the hands of israeli authorities. In israel. We expect the team from the us embassy to see them very shortly. Or the coming hours they will receive any support and assistance they need. And of course, were very anxious to be able to re an item with their loved ones. 59 year old you to turn on and his 17 year old daughter and naturally were visiting a couple whats new because of buddha, as positive a trip to israel to celebrate the jewish holidays. They were abducted by humph gunmen as part of the deadly rampage. And to israel that so around 200. 00 captives dragged into gaza. Judas, rabbi in illinois, spoke of his communities relief at the news of this safe return. The phone didnt stop ringing every 2nd and all the community wanted to know if this is true, people reaching out from all over the world. So clearly people are very touched by this and we are beyond over joyed with this news. At the same time, its important to reiterate that there are still over 200 hostages in the hands of terrorists. Loved ones of those still missing says how to is a 200. 00 empty places at us about do not. Intel are viewed, praying that soon they too will be coming higher is realize planning to evacuate, the Northern City of cutie are trombone up near the board with love it on the following days of classes with has full of fighters. The city is home for 20000 people and its just 2 kilometers from the border. Is really, authorities have been steadily evacuated in communities along the northern frontier. The needle goldstein have driven up to k yet simona to pick up the father level to take him to south and out of range of rockets fires across the border by his beloved. So my father is revealing the idea that someone else we take him takes on that, takes it to, to my home and try since ive this is why theyre leaving sirens. Wail is a power outage of rocket streets towards israel from 11 on to yet simona has already been hit by those munitions. Yeah, i me say its time to go because this kind of about to ation allows b i d f to expand this operation of freedom to act against the hezbollah tire business. Civil people. Many residents have in fact already left before the enforced evacuation for the confident no return or action with the situation. Hes here right now, is there a difficult like my body to say . But you know what were going to in . No one is can be tough. Thats no one is, can be done. This is not all over the world. They dont understand. Were going to fight and fight on residents splitting the law. So now joining tens of thousands of israelis who have left the homes in the south near a gaza. Many countries are seen an increase in violence related to the conflict police in london report. A sharp rise in both empty islam and anti semitic incidents are corresponded travelers chosen pill has been meeting members of one of those Jewish Community to say, hey, crimes and intimidation are soaring. A message quickly confident, but not easily raised, anti semitic vandalism targeting a Jewish Community in london to k, seeing a must have search and hate crime since the outbreak of the israel him asked for leaving many feeling anxious and unsafe. I am really a with lily, a bets divide the holocaust deluxe to today. She uses social media to educate a new generation. Im horace of the past. Now a great grandson says hes felt afraid to show his jewish identity in public. And its gary to be able to, ive never felt this way in my life before last friday, when i had of come us code for an International Day of jihad across the wilds. I said for the 1st time in my life, i posted the tweets about this that i felt scared. So why im like it pol visible joy signed in the street from london. But i also put one message that which is that my great grandmother to 5 to holocaust. Not so that people like maybe skaggs and intimidates as in terrorist out of wearing lodges, symbols with pride, incidents across the u. K of raised from assault and abuse, to damage to jewish property. 2 schools in london, golden, red paint this week several closing the doors and tiny as, as they are being targeted. Some parents seem to keep the kids at home in higher education, welfare, helpline, and supporting jewish students facing increased anti semitism on university grounds. Campus has been horrific for students over the last week. We are seeing your students come from including us, scared to express such evidence to students a cooling us offering whether they should we go into campus. We are seeing do a student spacing throughout the physical assaults. And unfortunately the figures are when you go, they often times about the specific incidence a charge, the monitoring anti semitism in the u. K. Says so it was more than a 700 percent increase in incidence in the 12 days following the october 7th. The text. Yeah, thats the highest ever times who reported in that time period, the organization, which one of his anti muslim incidents is also reporting an increase. It says that was a 5 fold rise in cases across a 10 day period. U k. Government says, oh hate crimes will not be tolerated. The immediate warning that events of brewed coffee used to say c for division in the u. K. For them its passion, extra 3000000. 00 pounds in funding to come back to anti semitism. There are also 1000. 00 Additional Police officers patrolling the streets. These measures are being welcomed by the Jewish Community. The one school leader, one safety can never be guaranteed. Its really projecting a message. Is that the jews in this country all, not safe. I think the as a community, we will stand our strong against any of those actions. But at the same time, i do think that it reflects a concern that there are people Walking Around and also saw today that rather than condemn the actions of come us to think for some reason that that means that they can also write to the an anti semitic man, a parents faithful students. Vigilant security stepped up the pain over whats happening, thousands of kilometers away, vibrating on the streets. The u. K. Is communities watch events in the middle east unfolding. Hara, many dreadful could follow at home. Of the conflict is also prompted pro, posted in protests around the world. Here in berlin, theyve been banned because of fears of Public Safety rallies and support of the palestinians have gone ahead. All the same despite the ban. Hundreds of people have been arrested so far and that has raised questions about free speech and the right to demonstrate. For the seems like desktop, played out your tongue. Bell lane streets, large groups of angry men throwing rocks, both tools and even fireworks that police who responded with walter, common hundreds have been arrested. Parts of the city have been on a knife edge since police fund pro palestinian protest with the official saying such gatherings have been used to incite hatred calls for the killing of jews or the destruction of israel about their small skin barrel in worship, or c bonding protest is the wrong approach that started to diminish should be the possibility is this also included in german law for demonstrations as long as they are not violent to this end up applying this. So you have the feeling about the german state use of freedom of speech when it wants. That means freedom of speech movie is really citizens, but not for the palestinian citizens to do for this. And then just look at the Spanish Speaking at the jury school in the capital, the head of the center, right, cd your party said he box, the bond is good to go. So that will have to be a band on activities against people on this. We have not turn this off, and of course it will also have to be a band on demonstrations machine. So if what happens is what we have seen often enough or too often in the last 10 days name is namely that that has been violent demonstrations here. To that, an echo of the political mainstream for gemini, the focus know very much on 0 tolerance of anti semitism. Lets take a look at whats some other stories making headlights around the world. Or 2nd, former lawyer for donald trump has agreed to testify against the x president , candace chest pro pleaded guilty to filing false documents as part of efforts to overturn problems 2020 president ial election laws in georgia. Even fire and find and sent mr. 5 years probation to prove that request. He was republicans have dropped jimmy jordan is as theyre now many for how speaker the hard line from ally failed. And his 3rd bid for the job as members refused to back in the house has not been able to function since the last speaker Kevin Mccarthy was i was did 2 weeks ago for this is andrew watching data in his line from berlin. Heres a quick reminder of the top stories were following for you at this hour. Egypt is hosting an International Conference in cairo in an attempt to end the conflict between israel and the months. Egypt president says the only solution that has an independent palestinian state not in the history of, nor have months or attending. And the 1st e conway allowed in 2000 since the attacks on israel has brought in food, water and medicines for nationals trying to lead concept or hoping they will now be allowed to leave. And thats all for now, but to stay tune coming up next tomorrow today and looked at whether digitization could help protect the environment or until bruland. Thank you for joining us. The most cities they have a key to sustainable season students. And so theres no devouring any see the world as a dissolution. Griggs intention, telenetwork the centralized control. The megacities of tomorrow. Most climate frame be tomorrow today. Next on the dw. But well tell you the story. We have a getting a visa is more difficult than finding gold hosted to use force and for the future in the stories and issues that are being discussed across the country. News africa. In 60 minutes on d w. The news. Im just trying to and have a site to make the right decision. Dw news on the ground to follow the know what days we shop online, watch movies online work online. Digitalization is everywhere, making our lives easier, but it needs energy. All lot of energy. Todays data centers and cloud to gobble up around 3 percent of the electricity produced globally and consume more every year. So digitalization is not really sustainable or is it can Digital Technologies also help us protect the environment and slow Climate Change . These questions and much more this week on dw science show. Welcome to tomorrow today the 2 months on top of the 70 sleet. As i go to work at the institute for ecological Economy Research in berlin, we meet them at the Cities Museum of technology, which is home to an exhibition called the network about the history of modern communication. Analog systems have given way to digital once the birth of the internet drove digitalization forward at a frenetic pace, and thats impacted the environment. Thank you. Tennessee will photos of toys utilization already accounts to 2 to 4 percent of global c. O. 2 emissions on about 10 percent of global electricity consumption. And my Research Group once kind could i did that if the incident where a country it would rank stood worldwide and electricity demand after china on the us. Thats because the net is much more than just a cloud of ones and zeros. In effect, detecting that to bottom line is that behind all these digital applications behind the data streams, theyre also very concrete material. Infrastructure is data centers, cables and of course all the devices and to get a to which are growing a number by the day. Take smartphones, the majority of people have one these days and the average user buys a new phone every 3 years or so. And were in general buying more and more devices that are meant to make our lives more intelligent, like those integrated into what are called smart homes. But just how Climate Friendly are those homes actually . Data from sun, thatd be great. Just to kind of show it in a connected home is with heating energy, energy smoke control certainly can count the amount of energy use sites. English bought them by automatically reducing the temperature in unused rooms for instance. Or if the heating unit communicates with the windows but even so overall smart homes are still under performing when it comes to saving energy until beams and fly in the one major problem is the launch number of additional pat. Just devices that arent designed to save energy, like surveillance cameras or smart tvs and speakers and this stuff hands it once you add them to the equation, the impact is no longer positive and independence, which meant positive you. But also the main problem with over equipping with digital devices is that a piece of hardware, as ecological footprint is mostly dictated by its production rather than its use of positive. More Conscious Consumption would help. We should try to buy fewer devices, use them for longer, and pay more attention to whether they were designed with recycling in mind. The few of us do guns, fish dish or to make devices most sustainable. Its crucial to use them longer. That means im having to be built to be more robust above all, with the modular unrepairable design. Some companies have to both offer Software Updates and provide spare parts over the long term tyler titan. Some Campaign Groups have called for a statutory right to repair an issue. The European Union is looking into despite drawbacks and criticism. Some applications really are helping us to live more sustainably like mobility. Yeah, thats that help you get from a to be candid Climate Friendly way for those that enable you to trade items or buy used products instead of always purchasing new ones. Streaming videos for hours on end however, is problematic. An estimated 3 and a half 1000000000 people now regularly watch videos online. Thats almost half of the worlds population. Streaming streaming already accounting. So 60 to 70 percent of the global data. Yvonne, you can transfer williams hours. One way to make streaming a bit more sustainable list to turn down the resolution, especially on smaller display, fewer pixels means less power consumed in the data centers that drive the network world. If im off for the Energy Consumption for things like Cloud Computing data centers, a Network Infrastructure is old rising rapidly in the front put region, for example, the Cities International apple is no longer the top consumer of energy use up to date to send us off with insulin, according to estimates they are now responsible for around 20 percent of the cities, total power consumption to mine missing today to send as urgent need need to become truly climate neutral. So sourcing electricity from Renewable Energy sources and not just selling indulgences to compensate. Yeah, and to show up last time plus funded some needed to ensure more chopping of waste heat from data centers and what stood servers warm up as they were and have to be cold. But the resulting waste heat could itself be used according to the association of the internet industry by 2030. The waste heat from all of frank for its data centers would be enough to in series heat the entire city. But in practice, its potential has barely been tapped so far. The infrastructure is usually lacking. But there are a pilot projects in the works and the future waste heat from one of the cities Largest Data Centers will be siphoned off the heat. A new housing developments. Now thats a really smart use of digitalization. Another smart idea is heating with water. For millennia, people have used the power of moving water to grind green and irrigate fields. Nowadays, we also generate electricity with hydro power plants. And one river in central germany is now being harnessed directly to heat homes. The wide else, the river, and the german state of julian has energy good law heading in its waters. And not just the kind thats able to keep the wheels of this meal running. Engineer ingle miller has installed a heat exchanger in the channel running through the mill. The river water is used to warm up a mixture of brian and water flowing through the pipes to provide heating. Does the brian water mix front of the heat pump that flows through these pipes or sometimes minus 2 degrees when it arrives on as it moves through the Heat Exchangers warmed up to one degree ink. And that temperature difference enables us to produce up to 60 degrees as soon as i caught a quarter till like in geothermal, heating the brian moore. Its a mixture thats been boned by the rid of water, is vaporized, then transported in case useful to a higher efficiency heat pump. This guys flies to squeeze this vapor, and this generate t t like with a bicycle layer pump. So at the front it warms up when you pump, it looks well for the system to look the reasonable to con, dry up on the white l stuff. Upstream dum. Guarantees a minimum flow even in dry summers. The device now installed in the river hates the mill and the accompanying house. Oh no, ill punch down that isnt worried about his neck stating bill it is my house is really cozy. Now, if i were to heat with oil or down the cost is what the astronomical for me i couldnt afford it. Condition is beside currently, almost everyone in this community hates which fossil fu
