is 2021. the technology behind it is cold director here capture. eat collection times extract the carbon dioxide with high tech filters and fans. first they use heat to separate the carbon dioxide. then it is mixed with water and injected deep into the earth. they are, the carbon cools and solidifies, and no longer contributes to global warming. the plant is the largest of its kind and can capture and bind for 1000 tons of c o 2 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's the 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 caea to the plant. we have an ice length. its efficiency is higher than 90 percent,
4:46 pm
which means that for one come we are capturing. we omit about 10 percent, so we make about 100 kilos. plane works 1st direct here. capture plant went into operation in 2017 at the swiss site. the c o 2 was not stored in the ground but uses fertilizer and nearby green houses. 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 at 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 have only had limited success, seth, a j gambit of impure college london. much older. so i'm ologies with common culture storage, which they so the seo to out the atmosphere is such but actually capture carbon
4:47 pm
dioxide from the combustion. fossil fuels and things like that, industrial manufacturing, glancing poll gas light stations. and that comes out from storage. technology has been a bit of a disappointment in terms of the rate which has been able to be pilots. it's demonstrated in standoff, 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 pon guts. 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
4:48 pm
a lot of carbon per square meter, but every year around, $15000000000.00 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 to 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 route. drones wants to use similar technology to plant 1000000000 trees by 2030. the seed copter plant trees from the air. drone selectively spread seed falls over areas to plant new for us or to strengthen weaken for us. a drone can carry 10 kilos of feed ball each holding 4 to 5000 feet. this technology offers new opportunities for reforestation,
4:49 pm
says the raj petty, co founder of margaret drones. india is a very witty, evaded geography, and that in like desert him rather than the ice in that are gone, are among rules in west bend for there are many regions of people are unable to reach for. there are not many activities that are going on at present here, that can please be serious. unbeatable area with is the for sewing the drone 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 miseries they can be done from specific algorithms, which can process the image to create the optimum. and with unlike understand optimum environmental parameters. but a maximum plan growth. so based on this information,
4:50 pm
we understand like which spot of the forest needs to be taken care where there is in the very low growth of 3 covered. and also, what is the optimal seed bulk on progression that needs to go in? artificial intelligence is decisive in monitoring the a for a 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 the area of india to meet one companies, carbon emissions rather than just actually get to fossil fuels. so these can sometimes be being the unintended impact of being a distraction from much more positive 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 shock for nearly 800000000 people were
4:51 pm
wide? 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. adding is delight the going to get out there for study, falla, there at a youth and he visual freezer. if i don't want to be muffled full on life in our mic, are they doing possess, coma, the cross all to put in the way the guy from the drinks? they're called glad erica will come by this community solar powered mini greece is
4:52 pm
designed to solve 2 problems at once. first, provide much needed access to electricity. second, reduce greenhouse gas emissions. the renewable energy p d centralized energy system works in remote areas. also, the national power group and intelligent control systems are able to capture any superfluous energy. the powergen company installed the microgrids for manager mohammed. so leo county is a promising concept. is community 5 years down the road? it was completely dug was low. today we have electricity here for me going for, for the rest of the all. this is of a good, valuable, offshore are microgrids or local solar energy greats. really, a global solution. we asked energy expert marie fo barza from kenya. microgrids,
4:53 pm
i'm not the be all and all seem up lead. so every but they're in integral part of the electrification process in the, in the global thought. like for example, the solution found by dr. m. a thing in the indian state of rochester. he has installed solar panels, both on his hospital and on the family farm land, missouri like i feel like i'm contributing to the needs of my village put live on it for 220 megawatts. and i am generating 5 megawatts here on my land regards, the new to go good. so i am contributing to 2 percent every single my village's power needs. i feel good about that. i know you regularly feed 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. there needs to be an understanding that is not centralized. great vices smarter. microgrids or vices standalone solutions. it's
4:54 pm
really what's the best solution within each context. oh, 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 pump. the kite is flown automatically with prevailing when conditions been taken into account. they fly higher than the tops of existing wind turbines. and i noticed in cool enter, kate 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
4:55 pm
a generator on the ground. he's either or not and get it out for you, but hug the kites, are designed to generate twice the power of conventional wind turbines. a decline only the small turbine blade tips are actually effective with summers. we've reduced our system to that and replaced the stability of steel and concrete with a very reliable control system. baton, which i didn't get to for that. so you're going 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 and greenhouse gas emissions. there are innovations, however, the technologies we have seen today are only a small part of the solution. the theo,

guardians of truth with my name is john dinner. and i have paid almost every price of being a journalist in a country like to a key taking on the powers that be they risk everything they want to kill me and they try me anytime. john, don't dar? asks activists, journalists and politicians, living in exile to which and what drives them too much on my shoulders. but i have to hold this weight because i'm responsible for the future of our country for the people far behind the past. the courageous effort against corruption and political crimes
5:00 pm
in our series, guardians of truth and watch now on youtube. d. w documentary. ah ah. this is the w news. live the world's biggest space rock. it explodes the and crude space act. starship lifts off from texas, but fails minutes later. the craft is designed to take humans back to the moon and one day on tomorrow.
