about hackers, paralyzing entire societies, computers than elsewhere. you and governments that go crazy for your data. we explain how these technologies work, how they can go in for but how they can also go terribly watch it now. you to ah ah ah, this summer here in germany and in many parts of europe, climate change seem to really hit home recent months have been so dry and hot that harvests have failed. forests have caught fire to right not witnessed in living

memory. and river levels have dropped. here the famous rhine nearly ran dry. the availability of water is something we've previously been able to take for granted, but as awesome as become f, a more extreme, a change in behavior may be in order. the conscious management of our precious resources is a theme this week on made detail. we use business magazine. the scarcity of water is by no means limited to just germany, as well as the problems on the rhine which made parts of the vital river difficult to navigate. other european rivers also suffered at least po, run with only 12 percent, its usual volume of water on the u. k. so it's hottest ever temperature topping 40 celsius for the very 1st time. it's agriculture so that the hardest from the drought instead of burying our heads in the particularly dry sand, about the impact of our changing climate,

though it surely time to act. a good way to start would be to make better use of the water that we have. blue drought in europe harvests are at risk. the natural environment has been hit hard. after so little rain, farmers need water from wells or innovative irrigation ideas. round water levels are dropping, rivers are drying out our storage reservoirs of solution. oh, this electrically driven cropped sprinkler system is watering a sugar bead field day and night to cut the high energy costs 3 li, chicago dean, is using his own solar power. but a far bigger problem is that he needs more ground water than he's permitted to extract. then get us probably him long. if we are to get this problem under control

long term via here, we need a network of storage reservoirs here in the north, where some of the water that unnecessarily wasted is captured in buff on made available and fit for sprinkler irrigation based on what spike muttered the sugar be that he's harvesting can also help to retain water in the region. so how does that work? the beat is sent in huge quantities to the local sugar factory. in the northern germantown of olsen, 80 percent of the sugar is water. the sugar is extracted, but they aim to re use the water that is unable to bring us a substantial amount. you can imagine that if you irrigate a field with about 30 liters per square meter and not wood water, $4700.00 hector's blue, that's the equivalent in area of $6500.00 soccer pitches. the collecting basin is where the beat water from the sugar factory is stored. the farmers use it to

irrigate their fields, and some of the water seeps down into the earth and replenish the ground water reserves. clouds pass overhead with they don't bring rain. the collecting basin was the idea of the district, the head of local water and land associations. we have an, an oil pond dotted with a germany globally and principle finished. and we will have to retain water in lots of places in response to climate change while because ultimately water is pivotal when it comes to climate change, you ma, vanetta, they will have to hurry because groundwater levels are sinking. the pumps of farmer huntsville, him harbor land, reach some 50 meters down into the ground. he has already extracted more groundwater this year than is permitted. and the electricity and running costs of the 5 pumping stations have exploded. capital for my you have the phone for me in

june alone, i've already paid 130000 euros for electricity just those 2 months. and july's bill is still to come in this order. you do fatality up. it's an x to cut water consumption. he's using equipment produced by an israeli company, specializing in desert irrigation. the drip irrigation system supplies his potatoes with water. they spun up pretty downwards. it saves me money because the drinkers lie on the cro league where the water is needed on the field, often face beneath connecticut. oh, the district water associations head has other ideas about how to retain more water, a local waste water treatment plant. he wants to collect the treated output and stop it running into the rivers and out to see it's another example of how they want to stabilize groundwater levels here.

life, that's what i is infant. in principle, the water has been completely purified to meet the latest standards on his bed runs into the basin its form here it is pumped into a woodland area, thus vasa, there, the water is filtered again and it seeps through the soil. this is the cycle waste water from homes is taken by the sewage system to the treatment plant. rather than pumping the treated water into a river, it's diverted into a woodland area. there, it's filtered additionally, as it passes through layers of soil. the clean ground water is pumped up to the service again, where it is sent via pipes to the farmers. they use the treated waste water for irrigation. the water from the treatment

plant comes to this area of woodland does matter, can be a hint, a can years down the line of remove it from the ground water again for field litigation and name treat which ca, bodine will also benefit. at some point, his sons will take over his farm and for them to getting enough water for their fields is set to remain a very hot topic and some encouraging examples that we'll hopefully catch on elsewhere. however, we also need to tackle the root cause of human made climate change if we're to stop it in its tracks. unfortunately, that's become less straightforward. since russia's invasion of ukraine, germany is rushed to end its reliance on russian gas has seen it. switch to even more polluting, coal fired power stations and environmental step backwards for sure. but how green

is natural gas? anyway? i'll to rover common reports. we cook with heat with it, generate electricity with it, and also save the climate with it. natural gas is versatile and cleaner than other fuels, so it's really become the post the child of politicians proving that we don't have to choose between our environment and our con and fossil fuel companies, the cleanest burning fossil fuel. the world needs fuels that are abundant, affordable, and lower carbon fuels like natural gas. but hang on the minutes, should we really trust the fossil fuel industry that's responsible for half of all industrial greenhouse gas emissions since the industrial revolution to suddenly do what's best for the planet? i'm probably not. so let's drill down and see how environmentally sustainable natural gas really is.

oh, broadly speaking, natural gas is a mix of different hydrocarbons. mainly methane. it's found in rock formations deep below the earth's surface, where it formed from the remains of plants and animals over millions of years. we develop techniques to extract it from there and have done so for decades. and global output has constantly gone up ever since. in the early 2, thousands refined processes like fracking allowed companies to access previously untapped reserves, especially in the west, the world's biggest gas producer. this spec to real boom. and behind this boom, there was one big promise that natural gas could clean up the power sector. you burn gas, natural gas, that is meat dime. ah, you get half the c o 2 emissions of burning co. this is james henderson who leads the gas research program at oxford university. so natural gas still emits c o 2 when burned. it's not entirely clean,

but it's cleaner than it's alternatives like coal, well generate getting the same amount of energy. and so the 1st step for many countries is to switch away such as comb, particularly in college and ration. and you can imagine this like switching a color stove for a gas heater just on a much bigger scale. so instead of building a new coal power plant, build a guest power plant or retrofit acorta plan to run on gas kind of like the industry is showing up here. ah, home. as a lot of relatively clean natural gas became suddenly available, it turned into more than just a fuel. it was now a bridge fuel making power, our economy with less of the carbon pollution that causes climate change. the thinking was this gas could be the bridge between fossil fuel power, past and future power by renewables. up until today, politicians and the industry pushing this narrative. and that's because it works in

this sector in the us. typically, gas has been a boon for the climate. naya is a gas market analyst, her research fun, bloomberg. and yet if you work a lot, us carbon emissions from the power back there from 2000 to 2020. the u. s. is probably in the leads in terms of the carbon to carbonite power and much of that can be attributed to the use of natural gas. it's no surprise them that much of the western world like the u. k. and the you have been following similar strategies. and there's great potential for natural gas elsewhere. you move to a country like china or india. black coal plays a huge role in the energy economy. they haven't really gone through that told you gotta switch yet, josh, that can grapple play a role as i feel like is a bridge view to a detox. nice feature, but all that is only half the story because there's one big problem with gas that

those in favor of it don't like to talk about much move simply speaking, once gaskets extracted from the ground, it goes into a refinery, west processed. ready from there, it's distributed usually by a pipelines to power stations, homes or businesses, or it gets cooled down and turns into l. n. g liquefied natural gas, and then shipped around the world. and at every single one of these steps, methane can escape into the atmosphere. methane as a greenhouse gas, that's 80 times more powerful and warming the planet than c o 2 or a 20 year period. it's invisible, but with the help of satellites or very expensive special cameras, it's possible to spotted move, climate change is happening. and natural gas, which is by the way, also called fossil gas, ultimately is a fossil fuel that will make it worse. the science is clear on this. if we want to avoid catastrophic global warming,

we need to be reducing our use of gas drastically. not keep expanding it in countries that still use a lot of coal, particularly in asia, switching to gas can still save emissions. but on a global scale, we need to start phasing it out. that switch from tulsa gas can be one of the initial stages towards reducing emissions. but of course, you know, ultimately as and when that switch has happened, gas then becomes the problem becomes the hydrocarbon that emits c o 2 when burned in facts if gas use were to continue to grow as plans, it would be completely out of line with our aim to limit global warming to $1.00 degrees according to a recent un report. plus every bit of infrastructure we build now will lock in gas use long into the future. new instructor, things like power, land, or elegy. journals have a typical lifetime of 30 years. this is arvin rubbing, humor. research is how to lower emissions in the energy sector. so when you build

a plan right now you make $22.00 is operation, lifetime will extend to 20. but the question is, you know, we do need natural gas, we are using that natural gas structure. we use closed 30 years from now. but despite all these warnings, it seems to be pretty much business as usual. a recent investigation by the guardian reveals that oil and gas companies have plans to massively expand that production. again, we put this to the gas industry. the i o g p said using gas to replace coal is a no brainer. that it's the job of energy companies to meet demand at the job of government to change that them on the edge. and you said that gas is critical for an achievable, affordable, sustainable, and secure the carbon evasion of the global energy system. they also respectfully disagree that there's no room for more natural gas. that's the thing that the gas

industry completely oh, the lows. this is lauren stockman, who had the research at oil change international climate advocacy group that they're locked in for this kind of fantasy that their fossil fuel is the one that is okay and can grow and it still has room for growth and that the others will will carry the burden of getting us to, to our mission is goals and there's really not a credible climate scenario in which gas can grow. but that really backs the question. if we need to use less gas, what should we use instead? well, most importantly, we should tap cleaner energy sources like wind and solar, which are by enlarge also cheaper. however, we do it, we need to cross the gas bridge sooner rather than later. because that's the thing with bridges. they have a beginning end to end. more cars are of course,

a major emitter of harmful gases as well. thanks to the continued dominance of the internal combustion engine. that's why there's been much talk of alternative biofuels are made from wheat or rape seed, for example. over the past 30 years, their production has increased significantly. last year, output reached $1700000.00 barrels of oil equivalent per day. worldwide. there's put that into context. united arab emirates produces almost double that amount of actual oil each day. recently, food prices worldwide have been soaring, driven up as a result of the war in ukraine. now the question is being asked, should we be dedicating farm space to fuels or to food but gas tank is no place for food. environmental step hung a banner on the reach, seed silo in the port of hamburg. they are angry that more and more arable land is

being used to produce biofuel, rather than to grow food crops. bill cuts tougher. imposing biofuel in cartons is environmental. nonsense i, we are facing a global foot crisis and turning valuable grain into gasoline is responsible for the german government has to stop this nonsense immediately. land food belongs on our plates and not in the tank. got often tell our mission and tank biofuel is mixed with conventional fuel to reduce c o 2 emissions in light of the energy crisis manufacturers believe there is more need for this than ever. be a kernel mayor. we could produce more biofuel, but we would have to focus on that one out in focus. but the moment i think germany is caught up in great change and impulse. but that's the challenges that we are facing. those are gigantic history. decent decant ish. farmer court anchor also has

no time for the proposed ban on biofuels. he supplies grain to a biofuel factory near the eastern german city of leipzig, but it's low quality grain that isn't suitable for bread making about 20 per cent of his harvest. his destined for the gasoline tank. thus this craig, north head more for wheat that can be used for bread after all, over the human for high quality wheat with a lot of protein for the past. industry probably get an even better price. i've gotten last of all, there's the wheat that is used for animal feed and bio ethanol. so let's go and put, all right, so the, i don't know if he sells his low quality grain to crop energies. the company uses it to make bio ethanol. and when they entered the market 30 years ago, they got subsidies from the e. u to take the surplus grain off the market. now they have become whipping boys because they produce fuel rather than food. the managers feel

misunderstood, they say they're not destroying anything that could go on people's plate. yeah, he has it's and for being primarily we use animal feed, wheat, risky, which is not suitable for baking. when we use barley and corn syrup, which are also not suitable for baking, as they are of animal feet, quality would accredited by a lot of c o. 2 is produced as a byproduct that can be used in the food industry. for example, to make fizzy mineral water under the product is protein that's used to make animal feel, saving the need to import soybeans from south america, where rain forests are often illegally cut down to make way for so i plantations. the biofuel company sees itself as a reliable local producer that can ease the pressure on germany during the energy crisis. somebody the avoiding them in 2021. for example,

i replaced 1400000000 liters of the fossil fuel gasoline lines with renewable by with and all that's, that is a basis. i'm for further reducing dependency on russian oil wasn't at a light notifying by the p. c. k. refinery in eastern germany was supplied directly by a siberian pipeline up to now, but at the end of the year, that's due to stop with the biofuel manufacturer could partially plug the gap and further expand local production. but opposition is growing much to the annoyance of verbiage o c. e. o. so we are in deutsch mantel junction plants are in germany, asked us, but we are not dependent on our product remaining in germany. as i can deny, i can only repeat the naivety and germany is so indescribable. only do i know what else to say, the fight mechanics. i other countries think about selves much more. and in the

current situation, that is what we should be doing to that we have to have a rethink biofuels, and bio energy are not just positive in terms of the climate. they also ensure security of supply for all of them. see, i'd be critics are unimpressed and are calling for farmers to cultivate food crops and nothing else. they want biofuels to become a thing of the past. and when the and the lose all we have the solution all to with feel electric cars are much more efficient than conventional ones for to some they are more climate friendly with us. we have to speed up the phasing out of combustion engines. latoya slowing, but biofuel manufacturers have a different idea they could gradually switch from grain to energy rich straw and min, newer from livestock pens. while

they say that necessity is the mother of invention when the need is at its greatest, that's when we start to innovate. as you just saw, another pressing requirement is the need for new ways to build 14000000000 cubic meters of concrete al produced each year, but at enormous cost to our environment. so what else could we be building with? let's take a look. hey, ever heard of this? you can build houses with god. ah, no joke. you can make concrete out of carbon dioxide. well, that's what i heard from a startup in canada. wait, right here. hey madison, can your company really make concrete out of the scenario? we can actually me concrete out of out of been here. what we do is we have a c o 2 embedded or enhanced supplementary material,

the very long word. but essentially it's an additive that can replace a portion of cement in a concrete mix. ok, not really concrete odyssey or to, but something that replaces a part of the cement. confused. let's break it down. concrete is basically made out of 3 ingredients, cement, sand, and water. and it seems to me that it is everywhere. right madison colgate right now is the 2nd house you substance on earth, other than water. currently, the rate of growth emitted the built environment is about equivalent to building one new york city every month. while building house has an infrastructure is a great thing with a little problem. this is the bad guy. the production of cement, emits enormous amount of c o. 28 percent of all greenhouse gases are caused by the

construction industry. that's huge. madison said her company has a solution, a substitute made out of surprising ingredients, industrial waste, like ashes and c o 2. when you have time to process technology and that kind of comes in the form of a very large reactor, especially how it works is we put our solid heat stops into the vessel. and then we pressurized that with c o 2. and we rotate the vessel for a number of hours. okay, let's go industrial risk like gotcha. and you are to ah, what's happening in the chemical process? the c o 2 molecule men of the lives with the industrial arches. it is as if the

greenhouse gas fossilize is a completely different material comes out and it can replace up to 40 percent of the cement the production does not emit greenhouse gas, it absorbs it. in other words, the climate damage in greenhouse god is tapped in the concrete madison. you want to build the future with a waste of today me project that by 2030 will be able to achieve 600 make tons of carbon reduction. good luck. using simon substitutes can to make the construction industry completely green, but it can at least make it a bit greener left some more ideas like that place we're going to need them. that's all over this edition of made data. we use business magazine until next time. take care a a,
