it will be an addition of values, you will be in a society as then they find themselves victims of their own a game. they see it as a voting a game. they see it as a presenting balancing there on the notes and policies and the victims. and in this game, of course, as weekends. okay, have a big new 5 life back home. as this must be for the war was waged by nato in the middle east and north africa. so palestine is a celebrating world teachers day, and your generation of students is certainly take notes. one might hope. over now to our correspondent maria for an option as meeting with one of the world's top 50 teachers. he's bringing all kinds of innovation to the classroom is all of jenny. a miss lays. yeah, a computer science teacher from the palestinian city of denise is one of the world's best 15 centuries. that's off to he won

a global teacher price of the creative and promoting interactive learning to have students or palestinian boys age 5 to $13.00, leaving the city that's mostly makes headlines together with a nearby refugee camp off the same name as an api center of a palestinian arms, the resistance, and for being a target of these really army lanes. the most recent one, the largest ground in error peroration into decades, was in july, it last of 3 days, and ended up with 13 dest, including 12, who israel calls terrorist, while palestinian c as liberators, as well as severe damages to infrastructure. many local youngsters struggle to see any bright future, something that he believes could be changed to education. the nature, despite the events we're leaving here in jeanine. we can evaluate and excel in all

fields and create a awards that originate from palestine in hunting innovation and promoting the extra range of experiences. so that's the posting in students can field global citizenship processing, and students challenge students from all the countries and compete with them. it has won a number of awards in the last 6 years, including outstanding future answer anesco sponsorship european commission, also for the team in the top 10 best teachers now and ward 5, the teacher is better than his student also. so i'm glad i for who, who was that? yes, i know that mister a, it isn't a competition and he deserves to win. it truly deserves to be the best in the world, because thanks to him, i've learned many things and benefit and greatly i've even become ready to program more advanced things than what we're currently learning. thanks to him. i have developed a greater passion for school. this to the staff i live coming to school,

to excel in my studies. and when i succeed, oh, go to university and become a doctor. god willing yard is also the 1st and only palestinian and the 2nd throughout the our world to be in and baffled to often merge q project a powerful educational to engage the students in science with 3 d objects and simulations. they can touch, hold, and interact with whether it's a solar system or a human body making learning, you're fine, and a flash or an officer. we need many label prizes. eod has pushed the government's through stablished, post times, own competition. the international award and scientific research that expects to embrace 40 countries to o'clock. the expectations of that's been 6 months. we'll have the open conference to introduce these awards. we will focus on the 1st part, food security. this means that the students bassoon and most as degree on solving

people's food security issues will receive a valuable money to reprice. the job now hopes to receive a letter and notifying him this has made it into the top 10 best teachers on the planet. so if it happens, you have to want to continue to compete for the main prize over $1000000.00. he's planning to actually donate to promote educational projects. in his homeland. they say big during his dodge was little steps. he, i believe the janine elementary school for boys where he teaches home to around $450.00 students would be a starting point for changes like better education and understand and to growing, make genuine difference across society. and perhaps one day across the world. notion at all t reporting from janine and palestine. yeah, you can see more of a marias report at odyssey dot com. well, that's it for me, real research at this desk here at all. it's international, it most good, but my colleague using a deal is here in hoffman. i was talking with

a whole list and a whole smorgasbord of your wife had lots of 2 of you can join union approximately the we are in contract, the land of fire breathing volcanoes. volcanoes vividly capture the imagination and they define our lives much more than you would expect. so what are they capable of and what makes contract as volcanoes stand up, the high acceptance. and i'm going to plan with you whatever you do. do not watch my new show. seriously. why watch something that's so different. several opinions that he won't get anywhere else. welcome to please or do you have the state department c i a weapons, bankers, multi 1000000000 dollar corporations. choose your fax for you. go ahead. change and

whatever you do, don't want my show state main street because i'm probably going to make you, i'm comfortable. my show is called direction. but again, you probably don't wanna watch it because it might just change the way and say we all know that the future is going to be one of renewable energy. but what kind of renewable energy, hydro, wind, solar, geothermal, they're all very popular sources of renewable energy that we have at our disposal today. and depending on the natural resources and environment, each country has its own unique energy mix of for, in order to optimize its energy needs. the, i'm christy i, today we're going to be analyzing the cost of wind energy. is it worth the investment? and are there any negative consequences to building out these massive wind turbine? the wind

turbines have become a prominent feature of renewable energy landscape, world wide. the energy is created by the wind turning a turbine that uses a series of mechanisms that change the speed of rotation as it leads to a generator. while there's no input cost associated with using wind to create electricity as opposed to coal and natural gas, it is difficult for countries to adopt the wind power as a primary source of energy. first off is expensive to buy or manufacturer, wind mills, and turbines. more over, there are logistical difficulties, such as changing winds, directions, or even inconsistency. the setup costs can vary depending on the location and the capacity of the farm. for commercial wind turbine, each turbine costs between $2.00 to $4000000.00, and this investment is expected to be recouped over a long period of time. on average, it costs around $1300000.00 per megawatt to construct

a wind farm. most commercial winds turbines have a capacity of $2.00 to $3.00 megawatts, but offshore turbines can be as large as $16.00 to $18.00 megawatts. to put it into context, a single megawatt is enough to power a 1000 homes for a month. once built, the maintenance cost is an ongoing expense at around $42.00 to $48000.00 per year. and this number klein's as a turbine age is given the wear and tear these turbines put up with every day. the blade tip regularly changes its speed from a $120.00 to a 180 miles per hour. in china, the us and germany are among the top producers of wind energy. they have invested significantly and harnessing the power of the wind to meet their energy needs. china ranks 1st in the world for wind energy, with a total of annual electricity output at over $650.00 tara watt hours. the us

is 2nd at $379.00 tera, what hours and finally, we have germany at a $115.00, tara, what hours. and as you can see, there's quite a significant gap between all 3 of these leaders in the space. in 2021, nearly 34 percent of global renewable energy investment was directed towards when projects and this highlights the growing importance of wind and our energy mix. when energy has become more affordable due to technological advancements with onshore wind power being one of the most cost competitive sources of electricity. generations, in many regions, wind turbines can operate with high availability, generating electricity up to 80 percent of the time, given a stable energy supply. but because of the constant movement of the wind turbines, these tend to break down over the course of 20 years and needs to be replaced often, even if they are well maintained. this compared to solar panels that are static and

can last up to 25 to 30 years. offshore wind farms are now of growing interest as these farms generate electricity from the wind blowing across the sea. and they're considered more efficient than onshore wind farms. more consistent, lack the physical interference that you have on land. the leaders of offshore wind include china as the u. k, and germany. so it's explain more about the cost of wind energy. we're enjoyed by professor trevor elector. officer of the wind energy engineering. a. so trevor, how has a cost of setting up and maintaining wind farms involved over the years? and what steps can be taken to further improve cost effectiveness says to me, of the cost of wind turbines have been dropping steadily and the last 20 years they've dropped at least 50 percent at least 50 percent. so when did you know, is comfortable to say anything up

a new power station so that it's level pegging with the fossil fuel industry. now wind energy is often praised for it's positive impact on reducing greenhouse gas emissions. could you elaborate on how wind power can play a crucial role in mitigating climate change? the most important thing is that wind turbines do not need feel past actions need co need gas. uh, that is, it's great advantage. and that is one of the reasons why it's cost effective. it does no, you don't need to buy feel to run it. the feel is free. it comes from the sun. is there any one form of energy coming into the service and that is from the sun? and the wind energy is actually a secondary effect, but some parts of the world have a lot more with the notice. so therefore,

it is very good in some places, not to notice the united kingdom is particularly good and we, the u. k. is one of the leaders in, in the, of the window energy. just for example, one day, last year, 70 percent of all the electricity made in england. it was from when the turbines, on average, it's about 27 percent of all electricity made in england. this is a, is when doing it, you, well wide wind energy is that'd be making about 78 percent of the electricity in the world. another reason why the u. k is so fortunate is the to, it has a very shallow coast line and you can erect off show wind turbines of show wind turbines are a lot more effective simply because you have lands breezes during the day. and if

you have not please is at night, so the wind is blowing day and night. and as wind turbines have grown in size and capacity, how has their efficiency improved and what innovations do you see shaping the future of when the energy efficiency of the wind turbine is, is dependent on the, the area of the, the wind to but the area accepting the wind and as this is, this is equal to pile squared is you know, that they, the distinction lodge of the radius. the greater will be, the amount of energy that you can collect as it goes up i squared, which means that to the, to wind turbines have been getting told her and told her and bigger and bigger. nowadays, you can buy the wind turbines with the radius of

a 130 meters. now that's a diameter of 260 meters. so these wind turbines at 300 meters above landel, above the sea. one interesting thing is that they, these 2 button uh, 2 by the so very large that you cannot make them off show because you can put them in the trailer and then try and turn the corner when you get to it depends on the road. they just to, to very low matter. i mean, the rate is a $150.00, so the diameter is 260 meters. so the answer is, uh, they made like an oil rigs they made um, off show on the, on the show line. now of all the renewable energy sources out there, thermo hydro solar and others where the wind rank sure the country's allocating more or less money towards wind, be joy. what should a wind turbine is?

is net number 2 in the, in the, in the hierarchy the most effective today is how do i like to just to give you an idea hydro electric to produce a 17 percent of the wells, the electricity wind turbine 7 to 8 percent. so and the cell is 84 to 5 percent. and so the wind turbine is a very effective way of making electricity and it is increasing daily. and china is particularly good on this. united kingdom is as well, usa is catching up a, the china is doing creatively as well on wind turbines. but it's such a huge country to need so much electricity, that even if all the, they are swamped being the, the amount of turbines being produced worldwide. it doesn't make

a huge difference to the total energy needs because the needs are so very, very large. thank you so much professor trevor lecture for all your time today. but when we come back, we will explain what are the obstacles when energy faces to produce the most energy . so don't go away. the take a fresh look around. there's a life kaleidoscopic, isn't just a shifted reality distorted by power to division with no real opinions. fixtures designed to simplify will confuse really once a better wills,

and is it just as a chosen few. fractured images presented is fine. can you see through their illusion going underground, can the know that'd be due to the missed the shower and the bone, the soldier monument was erected in 1947 in the estonian capital by the soviets. authorities originally built above the burial site of troops remains its memorials of the soldiers who gave their lives in world war 2 will say risk at the department service good morning. and frontier communications is delaney. in 2007, the stony government decided to relocate the monument from the city center for the year on that for me, for some color cops, i, me to a, to really the frustrated to move divided the population. estonia is large of

russian speaking community. strongly opposed to an intense rising pro college and tell in these have since become the as the bronze night drive across the well, when energy bring significant benefits, it is essential to examine the challenges it poses. now one of the big factors is that it is completely dependent on the winds of mother nature as to how much when is forecasted for the day. if there is no wind at all, then all of these turbine sit idle. when there's never constant and overall averages will have turbines, always spinning of 30 to 40 percent. they're rated capacity for onshore. the wind power also won't work everywhere. you need areas where the wind blow strong and

steady in order to make the investment worthwhile. even with ideal locations in coastal areas, hills and open fields, it doesn't blow all the time. and this causes intermittency when energy generation stops or slows down due to the lack of wind. now there are concerns revolving around the potential environmental impacts. earlier this year, 6 whales washed ashore and areas being prepared for large scale offshore wind farms . and while there is no specific evidence that the noise resulting from the offshore wind sides could potentially caused the mortality of wells, there is a strong correlation. and recent studies have shown that certain marine species such as whales and seals, might be affected by wind turbines, under water noise. a study by o she ought to raise the concerns about the distortion of marine species echo location ability due to the presence of these offshore wind farms. however, pro opponents of wind projects continue to claim that correlation does not imply

causation and insist that there are other dangerous to wells that are more of a life threatening risk such as vessel strikes and entanglements in fishing gear. additionally, noise pollution from wind turbines have spark debates and local communities. the turbine leads make a lot of noise as a turn and birds and bats can be kindred, killed or injured. despite these concerns, when the energy is the 2nd most widely use renewable energy source, with global installed wind power capacity exceeding 263 and gigawatts. and this account for approximately 24 percent of the world's total renewable energy generation capacity right behind hydro power. so for this and we're let spring and todd bubble, horwitz ceo of baba trading. now by the, if there is evidence that when energy has its faults, why do companies keep on pushing wind energy?

well, i think it's about money, right, is it's not it's got to do with whether or not it works, not because it does not work very well, has been proven that it's too expensive. it doesn't work very well, and we're really not equipped to handle it either. way, but it's again, it's about the patch credits, it's about money. it's about how much these companies can make by being in bed with the government trying to create these on the climate change products. and what are the primary challenges associated with wind energy that may hinder it's widespread adoption as compared to say, other renewable energy sources? well, i mean, there's really no exposure for fossil deals, or they can talk about all they want. but with the current infrastructure, you cannot produce enough energy to have those turbines that you need to spend the beginning of the work. you know, we, we, we've got one major problem in this country for as long as i'm alive. and that is that every presidential candidate is either i promised to fix the infrastructure,

none of them. so yeah. so what we have is a problem and you have these, these have hardened solutions that are going to work because we cannot personally get put where are you, how many wind turbines can you put up there? there's many wind farms out there that do not allow for the production of the energy that is needed. you know, we use a lot of energy, this country and we have not been able to, to master or, or satisfy the need by using when nor so are you. now why do you say that the government won't invest in this infrastructure when they in fact have poured millions of dollars into subsidies. while the mother is money and those who are producing and are getting, you know, lots of tax credits and lots of tax breaks, which again, is the same as money, right? you know, it, just as if you buy something again that you're, the government is giving you a tax credit. you're getting it directly off your returns. you're actually are getting paid what, no matter how they want to focus it. and that's, that's the bigger problem, right? we we have too many projects that couldn't. busy and we have no plan on how to use

them nor how to get there. and now many critics argue that wins intermittency compose res. # ability issues for the power, red power companies addressing this concern and ensuring consistent energy supply. well, that goes back to the bottom of it, right? you still need new energy to have those turbines disappeared into work, right? they don't just work purely on air only. and of course, you have a power rate that isn't capable of handling every day circumstances. i mean, we have, we have, we have blackouts when weather gets to watch certain parts of the world when you buy in new jersey data charged at night. because of course, the power root canals and what, because we, the, the country is not done a good job at focusing on fixing. the problem is that this goes back to, you know, fixing the lobbies and things in the katrina. right. they didn't want to fix up there to cheap. you guys are busy stealing the money instead of putting into words supposed to be. and the 1st thing you have to do before and it is progress in our

work, is fixing the structure of this country. but of course, if you go back to the colonial pipeline here and present vibes, the size of private companies that are problem, well, is there a problem? because we're very accessible to be hacked by just about anybody right? now. some studies have suggested that when energy projects might not be as economically viable as proponents claim. so what flaws and wind are they pointing out this? this will applies you use the windows not create because of your change of pending . we know the sounds on every day and there isn't a window where you guys are, is not enough to guarantee. i'm not, i'm not fuel. you can even get a guarantee and not using solar power, let alone wind power. and that's the problem you see when from where there's thousands of windmills running around there still can't drive power to power the right. is there any validation to the wind turbines affecting marine life and farming wales seals and see birds?

i don't know, but uh what they do, the environment specifically i i can't accommodate cuz. 1 don't know the answer. i would suspect not other than birds that tire, that bite flies probably get caught up and, and because you know, it was solar, the birds don't get slaughtered in the, in the solar panel. so i would assume similar problems would be in when, but i don't know that that would be any major factor. somebody would stop me from saying that would be something we would do. and now why, what consumers care about where the energy comes from as long as you have energy and electricity, is it only because of climate change? well, i mean, again we, we, we are not, we are not position to replace the fossil fuel. right? and when you go through the globe and you look around china and india are never gonna stop on the call and they represent 40 percent of the work they are going to can do. in fact, china is dropped any, any projection of the climate recently. and of course, it's nothing we do is going to change what 40 percent of the globe is doing. so we

can talk the nonsense and we can talk the climate change all we want. but again, the day we should be using fossil fuels using all fossil fuels and not worry about the climate yet. and joe, the government, who's behind us polio, says i for the, for example, josh, or want to put a plan together for the ones that was the one that's going to be right. and so i'm making ridiculous threats of i'm stopping, you know, different things like gas stoves, water heaters and things like this is totally ridiculous. and the positionally, our end is totally ridiculous. and the energy storage is often considered a crucial aspect of renewable energy integration. so wondering, a viable options for storage excess when energy and wouldn't, that is slight. the cost of the batteries are still very expensive. what was a, again, no matter what we do, we can't control what the rest of the world that, and we are only a minority of compared to the rest of the world. and again, if you have 40 percent of the world bonding call and china and india plus the rest

of them that are, how are you going to do anything we are the cleaning assembly united states is the cleanest country in the world as it is. so now you, you think you're going to stop over a bad day and isn't that best? have you believe it in climate change? and as far as i've or the world is i need to go to the climb for the last 50 years . and yet here we are still in the same position with the temperature change a less than a quarter of the degree. and now the thing is when energy better for urban or for rural areas. i still think that the best energy source that we have and the most for barriers for the fossil fuels. because again, they can burn clean. they can remain clean, and i have not had a dramatic effect on the environment. as the officials would like us to believe, i think more of them is across and, and really not realistic. and i think this is the story that has been told because we, we'd like to tell very tell. busy that are not really legitimate. thank you so much bye for all your time today. so is when energy actually worth it?

is it a worthwhile investment for a sustainable future? and we have the undeniable and advantages of wind energy. sure, including its cost effectiveness, efficiency, and its potential to mitigate climate change as it makes a crucial player with global transition to renewable sources. however, we must still acknowledge the complexities that accompanied this journey. the environmental impacts of wind turbines, concerns about wildlife interactions and considerations surrounding the grid stability call for stable planning and mitigation strategies. i'm christy. i thanks for watching and we'll see you right back here next time on the cost of everything . the

i look forward to talking to you all that technology should work for people. a robot must obey the orders given it by human beings, except we're so shorter is that conflict with the 1st law show your mind, anticipation. we should be very careful about visual intelligence. the point obviously, is to create a trust rather than fit the various mean with the artificial intelligence we have summoning the theme in the robot must protect his phone. existence was on the
