pull c o 2 out of the air and jones, the plant trees, digital innovations that combat climate change, our topic to day on shift, ah, to limit global warming to a maximum of 1.5 degrees celsius. greenhouse gas emissions must be nearly half by 2030. this is what the intergovernmental panel on climate change has recently reported. the consequences are huge forest fires melting polar ice caps and devastating floods. only by consistently avoiding using oil gas and other fossil fuels. can we stop the trend or could digital innovations help humanity? some of them sound too good to be true, like the c. o 2 vacuum cleaner. ah! near iceland, capital reykjavik, a plant the actively removes you to from the air has been operating since 2021. the technology behind it is called directly or capture. each collection times extract

the carbon dioxide with high tech filters and fans. first they use heat to separate the carbon dioxide than it is mixed with water and injected deep into the earth. the are, the carbon cools in solidifies and no longer contributes to global warming. the plant is the largest of its kind. i can capture and bind $4000.00 tons of suton per year, but it meets a lot of energy. iceland is night deal acacia because it has both hydro and u thermal resources. renewable energy is abundant and cheaper. it see only sensible way to run the plant. we are committed to use only renewable energy so we don't want to emit c o 2 while capturing c o 2. the plant we have in iceland its efficiency is higher than 90 percent. which means that for one tom, we are capturing,

we admit about 10 percent. so we're make about 100 kilo claim works 1st direct here capture plant went into operation in 2017 at the swiss site. the c u 2 was not stored in the ground, but uses fertilizer in nearby greenhouses. this closes the carbon cycle and prevents more carbon dioxide from entering the atmosphere. an impressive approach and it really works. but how much influence can it half on global warming? the plant on iceland can capture as much c, o 2 in a year as 250 citizens in the u. s. consume. similar projects such as storing c o 2 under the ocean floor has only had limited success, says a j gambit of impure college london. much older except technologies with carbon capture storage, which they suck the seo to out. the atmosphere is such that actually capture carbon

dioxide from the combustion of fossil fuels and things like that. industrial manufacturing plants in coal gas line stations and the carbon comes from storage technology has been a bit of a disappointment in terms of the rate which has been able to be pilots is demonstrated in scale. industrial c o 2 filtering plans can therefore only stop the rising global warming to a small extent. so let's take a look at a completely natural method photosynthesis. plants grow using only light water and carbon dioxide forests are especially effective at removing c o. 2 from the air, according to german climate expert, julia punk ups from all the a metro so called nitro solutions. forests are the ones that are probably have the largest potential. this is simply because it's large areas that potentially could be a forest. that and forests have a rather high carbon density, so a lot of in per square liter. but every year around 15000000000 trees are cut down

worldwide. this is for firewood or because the land is needed for agriculture, new roads, or settlements. grasslands and deserts continued to spret. this contributes to global warming. at the same time, climate change helps create even more grass lands. it's a vicious circle in spain rangers are trying to stop this trend using drones. they want trees to grow here again. in only 2 days, they have spread around 500000 seats. in india, the start up my roots. drones wants to use similar technology to plant 1000000000 trees by 2030. the feed captor plant trees from the air. drones selectively spread c balls over areas to plant new forests or to strengthen weaken forests. a drone can carry 10 kilos of c balls each holding 4 to 5000 feet. this technology offers new opportunities for reforestation, says storage,

petty, co founder of mark drones. india is a biddy, ready, ready, geography and baron lake deserves hundreds of fun that that ice in oregon are among rules in which bengal. so there are many regions fair people are unable to reach for their not many activities that are going on at present. so you've got that can be to these areas unbeatable areas with is before sewing the drones survey, the terrain afterwards, the seat capture continues to work. it monitors the seedlings from the air and the results are collected in a database to ensure healthy forest growth. so once the immensity stick and beat on some specific algorithms which can process this, emerged it to create that optimum input on like understand optimum environmental parameters for maximum plan growth. so based on this information we understand like which boss of the modest needs to be they can't get mad. there is thin avo,

very low growth of for the color. and also what is the optimal cbl concentration that near still going? artificial intelligence is decisive in monitoring the a for station efforts, but it can take up to 40 years for trees to grow and actually sequester c o 2. according to green i t expert chris adams. they talk about planting a ridiculous amount of trees as in them the, the area of india, i, me, one companies are carbon emissions rather than just actually kettle fossil heroes. so these can sometimes be and not having the unintended impact of being a extraction from much more important conversations. authority colonization. if we are to stop law the warming, we cannot simply keep burning fossil fuels such as coal, oil, and gas. but where will our energy come from? then? could you imagine life without electricity?

for nearly 800000000 people worldwide? that's the reality. most of them live in sub saharan africa. sierra leone in west africa is one of the least electrified countries in the world. only 23 percent of the population has reliable access to electricity. intelligence solar networks are set to change all that solar panels have changed life and to come to a village in sierra leone. there is finally reliable power from renewable sources. a great improvement people here had a youth delay the globe. he therefore study falla, they at a youth, any visual freezer, a fine, you know, going to be muffled full on life in our mic alley doing possess, coma. across all to put a new eric, i need this, they're called, i at erica will come by this community solar powered mini greece is designed to solve 2 problems at once. first provide much needed access to electricity. second,

reduce greenhouse gas emissions through renewable energy. with the centralized energy system works in remote areas off the national power grid and intelligent control systems are able to capture any superfluous energy. the coverage and company installed the microgrids for manager mohammed soleah county is a promising concept is community 5 years down the road. it was completely dark, both low. today we have electricity here for me going forward for the rest of the. busy this is of a good, a viable option, are microgrids or local solar energy grids. really a global solution. we asked energy expert marie for bras are from kenya micro grid and not the be all and all see up will at we saw everything,

but they're in the integral part of the electrification process in the, in the global south. like for example, the solution found by dr. am a thing in the indian state of rochester. he has installed solar panels both on his hospital and on the family farmland, missouri like i feel like i'm contributing to the needs of my village. co put live one for 220 megawatts and i am generating 5 megawatts here on my land. me garden it so i am contributing to 2 percent, every single my village is power needs. i feel good about that. i am the regularly feeds solar energy into the local power grid. individual projects which utilize a i can provide local relief. but other solutions are needed to meet the rising global demand for energy. that needs to be an understanding that is not centralized . great vices smarter microgrids or boss is stumbled on solutions. it's really

what's the best solution within each context the german company enter kite has an innovative and decentralized way of generating energy. it uses the power of the wind. there are no huge wind turbines, but instead a mobile system. the portable system consists of only 3 main components, the stunt kite, the control lines, and the steering cabin. the kite is sloane automatically, with prevailing when conditions being taken into account. they fly higher than the tops of existing wind turbines. like i'd noticed in cool enter kite uses the wind up high, where it blew strongly and consistently above to these wind turbines uses high technology, kate systems that are controlled from the ground and transmit the wind power via the lines to a generator on the ground. he's either a or not and get an artful,

but hug the kites, are designed to generate twice the power of conventional wind turbines. like little decline, only the small turbine blade tips are actually effective with summers. we've reduced our system to that it would see and replace the stability of steel and concrete with a very reliable control system. baton, which i didn't get super litzinger. i'm showing all the costs for solar and wind energy and for batteries are thinking they're down 85 percent since 2010. but time is running out. we must act now and make more use of modern energy technologies. the i p. c. c has warned that we have only 3 years to reverse the trend in greenhouse gas emissions. there are innovations, however, the technologies we have seen today are only a small part of the solution. the c o 2 vacuum cleaner won't help if we still burn
