downfall is awful cause for the coming day. and polls in mainland spain of closed in the country's general election an election that looks set to transform the country's political landscape the campaign has been mocked by its surge and support for smaller parties especially the far right. wing is up next shift living in the digital age thanks so much for watching. i'm not nothing out of the germans because sometimes i am but they sound nothing with the time and even to have been thinking deep into the german culture of. newton seem to think that his grandmother. it's all that who knew time rachel join me for me to get something to post what's the connection between bread. and the european union the nose gear. job you correspondent and the baker john

stripes this second line with the rules set by the team. smoking recipes for success strategy that make a difference. baking bread on d.w. . of you stream the video today i suddenly have and that's not good for the environment but i saw a lot of data in the cloud instead of putting it out so that should reduce my environmental footprint or does it just how green is our digital lifestyle today on ship. did you know that every google search consumes electricity zero point three you want always to be precise that's what a sixty watt light bulb. in eighteen seconds. like much but when you consider that

process is three point five billion search requests every day it adds up so should we do without google i can't imagine it to be honest even though it would save energy the internet is too much a part of my life. just of course like going to an actual store instead of ordering online or using a good old fashioned map instead about. can we make the digital revolution more sustainable we spoke with environmental economist stephanie. green world he tries to answer the question so what really is better for the environment. or streaming in generally speaking watching a d.v.d. consumes less electricity because transmitting data from the cloud uses lots of energy but if you drive to the video that increases the environmental burden. of.

twenty kilometers streaming is better than that a d.v.d. is better if you walk to pick it up a d.v.d. is always better than a cap and that's. the rule of thumb here is that it's best to print paper. talking about files and documents the cloud is a paperless office is the way to go. purchasing things if the market is more environmentally friendly online shopping. and then transportation packaging to both of which result in significant c o two emissions. of all the things you can do online. since it's a second hand online market. better than buying new one amazon. paper book or here it depends on your own habits the more books you read. in a printed version the greater the environmental benefits. the tipping point

comes between thirty and fifty books that's when it becomes greener than paper. shopping mall or online shopping a brick and mortar store is still more environmentally friendly delivering individual. energy efficient. working at full capacity online shopping could be more environmentally friendly ironically though when you shop online you're barraged with advertising which makes you consume even more. like she's very easy to do streaming storing files in a shopping online it will take just a few clicks but the fact is even and energy efficient process if you repeat it often enough and stopping creasing energy consumption so if you still isn't automatically green. digitalisation isn't going to increase the strain ability automatically. we need to transform society and the economy to make it sustainable

and then see what positive role digitalisation complaining that. digitalization doesn't always make things more environmentally friendly so it's worth thinking about which solutions are more beneficial take sharing platforms for example the sharing economy is booming nowadays we can share bicycle apartments in the name of and that called all of your for instance lets you share food that would otherwise be thrown away anyone can use it private individuals supermarkets and restaurants it's a clever use of technology what are your thoughts on this stephanie. sharing economy is a great idea. has been good for some things food sharing sort of thing. but it's important to realize that there are also some negative examples. so. there have been several studies on car sharing and this. concluded that people tend to

use car sharing instead of walking or taking the subway. so in reality it's like a substitute for buying a car to get out of the gulf so caution erring may actually puts more cars on the street and it doesn't seem to affect the number of new cars purchased and what about our buying habits when it comes to smartphones i'm already on my tenth which does make me feel a little ashamed and then just one of many people who always want the latest and best in these seven billion smartphones were manufactured between two thousand and seven and two thousand and seventeen at a high cost for the environment first the other raw materials smartphones use rare earth and precious metals from cobalt in the battery to india in the touchscreen they have to be mined and chemically processed all of which is environmentally damaging. even companies invest heavily in advertising to get us to buy the latest devices as a result many smart phones are replaced even though they still work that's also

true for computers t.v.'s kitchen appliances that can hardly be considered green than this energy consumption the more complex the device the more energy goes into making it and even surfing uses much more energy than you might think. that the factories of the digital age. sentenced to a vast amounts of data so that users can access it whenever they want with an extreme in a film using a search engine or storing clouds transferring this data he maps of energy. if the internet were a country it would be the world's fifth or sixth biggest energy consumer. currency mining is especially energy intensive minus one when bitcoins to make that computing power to keep the network up and running that powell helps to complicate complex mathematical equations to. verify financial transactions keep server farms

are being built to mine bitcoin it's estimated that each transaction consumes as much energy as a refrigerator freezer uses in an entire idea video streaming is also an energy hog it's a ready accounts for sixty percent of data traffic and energy consumption that set to rise. of the in germany data centers are currently increasing their power consumption by six percent a year for the worldwide that figure is ten percent of its official unless we generate this energy from renewable resources for all contributing to climate change. and around the world the number of internet users continues to increase last year it rose by nine percent. what can i do to save energy the internet of things or for short could help the i.o.t. is a system that network smart devices a washing machine and say well then only run when it gets enough power from your rooftop solar installation will be io t.

help or hurt the environment let's take a look. heating and cooling a building takes a lot of energy do light. it's estimated that hundreds that energy is wasted intelligent io t. systems measure energy use with smart sensors and send the data to the cloud. there it's analyzed to see how energy might be saved. as the internet of things continues to grow it will transmit ever more data and that too consumes energy not all of this data delusion is useful to the cloud or data center intelligent gateways can help it that data flow to pass on only what's relevant which helps save energy. these smart windows generate electricity built in solar cells transform light into power which you can even use to charge your smartphone. and smart senses in the windows respond to environmental

influences in order to help keep indoor temperatures pleasant while saving energy. so not even experts as sure whether the internet of things will be an environmental boon it will depend on two things how much energy the devices consume and how much data they transmit another new technology that could benefit the environment as artificial intelligence could i help save endangered species and maybe help save our forests at the earth live forum hosted by microsoft berlin some experts and environmental pioneers whether it can boost sustainability and arrived at some fascinating results. can process huge amounts of data in a short time that allows us to tackle projects that would otherwise be impossible. hey i cannot save our planet however i can tell you that without a i will not get there we cannot manage what we don't measure so we need to start

by mentioning earth resources so that we can little by little improve how we monitor model and ultimately manage earth resources for example the wild need project identifies and tracks wildlife populations photographs of animals are uploaded onto an open source platform for researchers and private citizens. system identifies each animal by its markings and other features and records of the location in time the image was captured that allows scientists to monitor migration patterns for example. and lets users trace the movements of an animal they photographed on their last holiday. to sylvia tierra start up wants to use ai to improve forest management in the united states the software assesses forests using satellite imagery recording species of the tree use their height and the density of the forest this information allows from. fission forest management biodiversity and

helps ensure the water supply. right now scientists that are focused on conservation and are spending hours just sit through images by using artificial intelligence you save the time why did you use to take one hundred days you can take only a couple of hours and that time is now spent back in research instead of sifting through images. most ai systems that seek to protect the environment are still in development. how effective will be remains to be seen. as processing all that data takes a lot of energy. for a project to be worthwhile it will have to be effective enough to offset that energy consumption. here's one thing you can do use a search engine that plants trees in directly of course because the s.s.

they invest eighty percent of their ad revenue and reforestation and conservation project for every forty five searchers a tree is planted it cause it is a search engine mask and the results are powered by big how about you could you imagine only going online when you really need to watching a film on d.v.d. rather than streaming it and using your smartphone until it actually gives up the ghost could changing our digital lifestyle help save the planet changes like this just a drop in the bucket compared to what's truly needed tell us what you think on facebook or on d w dot com. and see you soon.
