you're watching the w news coming to live from berlin. i'll be back at the top of the hour with another news updates for you. up next, our tech show shift looked at the energy balance of going online. i'm mary, and i haven't seen from me and the entire news team. thanks for watching the news. the news? loosely, the listen carefully. don't know how to go. i feel the magic, the discover the world around subscribed

to the w documentary on youtube. where all online, all the time, streaming, chatting or checking social media at the same time. many of us worry about climate change. so how much to our digital lifestyles, damage the environment, and can apps and tech help us manage climate, change climate protection and a digital lifestyle? can we have both? that's our topic today. on shift me, the a single google search use us as much electricity as an energy saving

a light bulb for 5 minutes about point 3. what hours? currently the internet account for more than one percent of the world's electricity consumption. that may not sound like that much, but it's in fact or internet use consumes more electricity per year than canada. 35000000 population and most of the power is used to do exactly what you're probably doing right now. streaming videos, the internet consumers more than $500.00 tara one hours of electricity, and almost 80 percent of use for streaming videos on netflix, youtube, or vimeo. similar platforms, less data and thereby, and tricity. we should download content instead of streaming it multiple times. watching the regular tv broadcast uses even less than the gene. you can also save electricity by playing videos for lower resolution. and if you're watching on your phone, you hardly notice the difference in quality. finally,

turning off your camera during video conferences can save up to 90 percent of c o 2 emissions. but how much of a difference can that make when other parts of our digital lives are consuming more and more energy like bitcoin? in mid april, the crypt currency hit a record high of more than 50000 zeros. even more miners on our hunting for kinds the server farms are expanding and all the minors are in a race against each other. because whoever is the fastest gets the new bitcoin, this consumes so much energy that these days entire power plants are being run just to mine bitcoin, this power plant in siberia used to belong to a nickel smelter and is now being used for bitcoin server far over in the us state, new york, this old coal power station, which revised and converted to gas solely to provide a bit coin farm with the energy it's it is that at present,

the global bitcoin block chain uses around $110.00 tara watt hours a year. which is roughly equal to the netherlands electricity consumption for climate researcher, you will not turn down this. this has become a societal issue. the crypt currency is like bit court already require lots of computing power was that they just, they grow. so to do their energy in solution. so isn't this also a dangerous development be from the climate? we need to look for a tentative to use less energy for many se crypto currencies also need to become cleaner. 70 percent of all bitcoin mining takes place in china where cold generated or is cheaper chinese bitcoin mines alone produce more c o 2 every year than the whole of denmark. this troubles china's government. and it also bothers in may most tweeted he was thinking customer purchases with bitcoin and said,

tesla may hark with a massive collection this late cause the price of the crypto currency to knows die from around 50000 euros to under $35000.00 euros. if bitcoin is going to be greener, it needs to use renewable energy. but if that even realistic considering how much electricity bit con uses its big competitor, if theorem is going another way, rather than having all computers in the network check transactions at the same time as bit kind of they are working toward having single computers through the verifying this could save up to 99 percent of the energy use. of course not old tech harms or planet. some can even help us understand climate change, better, like in and or to come. this robot uses big data to protect marine life. the battery powered blinder collect data on the iceberg. 868. hey. and transfers it twice. hello right. when it broke away from tom taylor in 201768. he was one of the

biggest icebergs ever recorded since december 2020. it's been melting in the south atlantic. the robot measures the effect, the melting ice is having on salinity temperature, chlorophyll levels. this will help us understand how melting icebergs affect water quality and death marine life. one important consequences of climate change is that the water surrounding the on the soft tick is getting warmer. this could really accelerate the melting of places, which in turn would lead to rising sea levels. so we need to understand these processes better. so that's one of the data from this region. even if we don't have much of that, it's really important ah, in the u. k. trends like the help the monitor river conditions with that high resolution images, they can actually document changes in the flow of course. and in

a fraction of the time it would take to do a field study, ah, researchers then work with the images to assess the effects climate change is having rivers, which also helps plan flooding protection. the research teams mapping the indian ocean near the same shelf, hoping that work will provide an ocean health check. the depth of the ocean on this bio diversity remain largely a mystery. now marine research is a using so not to mention the ocean floor measure on catalog the animal world that they are working with high tech submarines remote control vehicles and 15 different camera systems to create details. 3 or a day trip being processed by artificial intelligence. a good example of how digital technology can protect rather than harm the climate and tech isn't

just helping us collect and evaluate data. it technique combining a i with 3 d printing is helping to repair the damage. climate change has cost in our ocean just dr. pounds or canola high research as a catherine data to create virtual 3 d model of the color reeks. this is what such a model looks like. the scientists have algorithms and software examine the virtual roofs. and i can then help construct a cult official cover race, which closely resemble the natural structure. the largest official coal re from the world is constructed of the movies, where hundreds of 3 d printing structures in fastening to the ocean floor. living coals were planted on the ceramic and concrete mulkins. the world's coral systems have been severely damaged by climate change. the hope is that 3 d printed greeks

can help preserve for may or even help systems recover. that corals can only survive if the oceans don't get even warmer. and although the international community signed the paras climate agreement, which aims to limit global warming to $1.00 degrees celsius by the year 2100. right now, it doesn't look like we're keeping this goal. some say there are alternatives, such as geo or climate engineering. these are technologies that intervene in our planet cycles. computer models exist of how these could help reduce the seo to getting into your atmosphere or stop too much sunlight reaching the earth. here's how they work. the airplane could disperse millions of terms of so pure acid in the stratosphere, the cell for what combined with water vapor and create arizona which reflect

a part of the sun's rays so that the atmosphere underneath one step less. but we don't know what long term effects such an intervention would have. just come to that matter if it could have dramatic effect. it could disrupt the monsoon or other large whether phenomena. we could see significant ground floods or other events. these technologies are untestable attention and to be in one area of research that has been pushed for years in carbon capture. and now there are several technologies intended to filter c o 2 out of the atmosphere and counteract global warming. thousands of c o 2 collectors would extract the gas from the atmosphere or filter it out from power plant chimney's. this would relieve the atmosphere of c o 2 and help curtail global warming. the filtered c o 2 could be stored indefinitely and former natural gas facilities like in this pilot project. in iceland, however,

there are answered questions surrounding this technology to but it's you, it's the question with c o 2 storage is whether you can store the c o 2 i've been captured. because unless you store it where it is being captured, you have to transport it, which is very energy intensive. you engineering radically altered nature, and the consequences are still very much unknown. so before we find ourselves, depending on it, we should do a bit more for a planet ourselves. and there are apps that help we can all do something to help protect our planet. one possibility is using environmentally friendly search engines, like because the company has helped plant more than 100000000 trees and more searches, the more trees flaunted ocean here was another search browser extension. select money to help clean up the engines with a german plate. plastic scanned bulkheads of items packed in the loss of plastic

and get re enroll. tentative stamp database currently contains mostly or in products, but more of being added replace. lasting, available for ios and android. also also master key creates an email template that you can send the manufacturer to let them know you think the packaging is walle. can such measures really help save climate? those who want to test the impact can register for a simulated climate time travel due to start soon. scientists hope the online games kiara will prove educational. this is post by which card do i draw? how much do i travel? i? so on devices in the simulation didn't see the effects this has on climate change today. also tomorrow. and in 100, you can see the package you can have as an individual was a crude and we can whole learn about our behaviors. consequences and researches

could also find out who would be ready to do what from gamers, which could lead to viable policy and business recommendations. but let's get back to our initial question. how good or bad are our digital lifestyles for the environment? i think the answer isn't clear, but i'm definitely going to pay more attention to my environmental footprint. and if you think about it, we can all have a big impact with little effort. some people worry, we've lost the fight against global warming and think fleeing to another planet could be an option. it must have plans to fly to mars with a rocket, which was explained on our youtube channel. check it out to find out why mars can substitute the earth as our home. that's all for me for today by and see you next time. ah.

100 percent evolution 0 percent emissions a rocket given between a motorcycle and and a bike with battles. and it tells me the ac kilometers now on me read on the w o o the news is increasing every year. many i'm gonna working on landfills to work very holiday destination drowning and the way we look at the year 0. 1000000 tons of ways

there another way. after all, the environment isn't recyclable. the make up your mind. d. w, made for mines. i know you need to be quite bored to the we are living during the most extraordinary time history of transport fully electric.
