is the same, the company is supplied engineering services to ship brothers and some petersburg and the black sea region. indeed, the sanctions intended to undermine russia's economy, haven't exactly come to plan with the us treasury. so we can see the what the oil price cap on russian that is the ex was, is when it results by mosca does point to some reduction in the effectiveness of the price gap. they have added to the shadow fleet provided more insurance. and that kind of trade is not prohibited by the price gap. now we have only come over guys, foot richard was and he says, the u. s. should be responsible for repairing the damage done to you in businesses because it was washington that initiated the sanctions. the us insist on damaging the routine economies and is it's getting what it's asking for because us has very much control 0 being commission. essentially, these sections of repair being requested by the united states of america for europe

to adopt orleans because it is quite a valid question. and the sanctions and also from a corporate view point is point of view last design could business of damage. so i think it's very sensible that as low as soon as broad, and i do think more, most of the 2 people, because it is a matter all right and wrong. whether these sanctions, all actually, right. and when the damage and dense inflict it needs to be compensated and really european governments to get the money from the us. well, but, so for this thing is out as always, is going to have your company here. let's see, i'm allow me the,

[000:00:00;00] the 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. i'm christy, i, today we're going to be analyzing the costs 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 worldwide. 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 winds 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 to the setup. costs can vary depending on the location and the capacity of the farm. for commercial winds turbine, each turbine costs between $2.00 to $4000000.00. and this investment is expected to be recruit 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. 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 terrel. what 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, the wind turbines can operate with high availability, generating electricity up to 80 percent of the time given a stable energy supply because of the causing movement of the wind turbines. these tend to break down over the course of 20 years and need to be replaced often,

even if they are well maintain 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 are considered more efficient than onshore wind farms. more consistent. unlike the physical interference that you have on land, the leaders of offshore wind include china as the u. k, and germany. so let's explain more about the cost of wind energy. we're enjoyed by professor trevor elector, officer of the wind energy engineering. 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? festival of the cost of wind turbines have been dropping steadily and of 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 leveled pegging with the fossil fuel industry. now wind energy is often praised for its 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 the post asians need co need gas. that is, it's great advantage. and that is one of the reasons why it's cost effective. it does not, you don't need to buy, feel to run it. the feel is free. it comes from the sun. there's only 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. we need to know this. 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 was from wind turbines. on average, it's about 27 percent of all electricity made in england. this is um, it is when doing it too well wide wind energy is already making about 78 percent of the electricity in the world. another reason why the u. k. 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 lansing 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 is their efficiency improved and what innovations do 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 areas accepting the wind, and as this, this is equal to pile squared is you know, that they, the destruction lodge of the radius. the greater will be, the amount of energy that you can collect as it goes up a 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, a 300 meters above the lando 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 god. yeah, i mean the radius is a 150, so the diameter is 260 meters. so the answer is, uh, they made like an oil rigs. they made an offshore 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 countries allocating

more or less money towards wind be jody. well, should the wind turbine is, is net number 2 in the, in the, in the hierarchy the most effective today is how do i like to, uh, just to give you an idea hydraulic to produce a 17 percent to the wells. the electricity wind turbine 7 to 8 percent. so and so those are the 4 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. the china is doing and 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 way the release of russian states never is as tight as i mean most on skiing

dress ingles all sense and up the same assist. you must be the one else holes. question about this, even though we will bend in the european union, the kremlin machine, the state on rushes to day and split the r t spoke neck, keeping our video agency roughly all the band on youtube. the question, did you say even twist, which is the 9 meg most and said 3400000. so this it vehicle call yet no blessed assess that will certainly be should use. so just appear to me. i don't need to let us, but that's the algorithm this,

but i'm not physically the showing is the one on the desktop or joseph. this alex is low to me on i. it was the most of the beast to almost 2 months to get continue listening to me as though assistant. certainly if i don't take it easy, it is a new of one of the with the on i box, which is cool, which you put in the 6 in a little boys. even though lynch stuff coming out of the stuff, you got you on the the, to assess the images i was outside. so the saw snow say on the freeze on us. so you, they feel political. some on i saw that about to some, the saw the english american law, so much stuff, you know,

much missing stuff. you'll see lots of deals is does the run that up to you last, but they were 5 you does is a, by any other notes on the pro much he's finding a viable and open the look forward to talking to you all that technology should work for people, a robot must obey the orders given by human beings accept. we're such orders at conflict with the 1st law show alignment of the patient. we should be very careful about our personal intelligence. the point obviously, is to great trust, rather than to the various jobs with artificial intelligence, we have somebody with theme and the the robot must protects his phone. existence was long,

exist. take a fresh look around as a life kaleidoscopic. isn't just a shifted reality distortion by power to division with no real opinions fixtures designed to simplify. it will confuse really once a better wills and is it just because it shows you fractured images, present it is, but can you see through their illusion going underground? can the while when energy bring significant benefits, it is essential to examine the challenges of pauses. now one of the big factors is

that it is completely dependent on the winds of mother nature as to how much when this forecasted for the day. if there is no wind at all, then all of these turbine sit idle. when there's never constant, an overall averages will have turbines, always spinning of 30 to 40 percent. they're rated capacity for onshore. wind power
