Breakthrough in renewable energy - VPRO documentary
Vložit
- čas přidán 4. 05. 2016
- It’s not in the papers but a silent revolution is moving across the world. Renewable energy is becoming cheaper than from fossil fuels. It means that progressively the choice for wind and solar energy is no longer an ethical one but an economic one. And this will speed up the transfer to renewable energy.
In countries like Brazil, Australia, Chile and parts of the United States people consider renewable energy because of financial reasons. The price of solar and wind energy will continue to drop and in more countries renewable energy will occur.
A surprising newcomer on the market is Morocco, where the government expects that in 2020 more than 40 percent of the energy could come from solar energy.

I am so proud for working in solar energy industry, for our meaningful work. We saw the EPC cost of Per watt from 10 dollars down to 0.8 dollars, this make the solar power cheaper than thermal power, deeply touched by this video.
It’s a bunch of crap ‼️
I'm starting in the solar energy industry do, you have any tips on learning more info about solar energy?
Tell that to, the poor people who slave labor to produce the raw earth material to make you green energy. Now they live in a wasteland of polluted earth.
I live in Tenerife, one of the islands next to El Hierro and the amount of solar panels here and wind turbines has exploded in the last few years, it's a great time to be alive. Great Documentary !
I also live in Tenerife and the system in El Hierro was supposed to make the island 100% ecological. However 60% of the electrical energi there is produced from oil.
Bad calculations? I guess they need to double the size of the system. Pretty straightfoward to do.
Its great to see many countries are taking renewable energy very seriously, especially to the point where fossil fuels are now being seen to be too expensive to produce :)
They always were, without massive subsidies.
Ain't no 'merican gonna touch this devil teeechnologee. We gonna burn God's own blood - OIL! Geddit bubba?
@@norwegianzound Burning Gods blood! What animal or human are you needing to take to the alter for sacrifice and appeasement?
They really aren't. What you just saw was a very onesided documentary.
Renewable energy!? 🤣 What will u do when those wind blades or sun panels finish their life? Where will u fill them up?
I love the lake and the dam battery storage of energy. You no longer have to rely on the sun shining or wind blowing all the time. You just use the solar and wind power to pump water up to the lake and let the water run out of the lake into a dam to get hydroelectric power. As close as we can get to a perpetual motion machine.
pumped storage is an old idea which depends on large differences between supply and demand at different times of the day.
the water is pumped back uphill using off-peak electricity which sells at a low price, due to low demand, while the normal generation gets run at peak demand and can sell its electricity at a high price. You lose about 30% of the energy over the return trip - it is definitely not like perpetual motion... Will it still be worthwhile when there is an abundance of energy and the price differential between peak and off-peak power falls?
Dick Hamilton I think they use renewable energy (wind and solar when it's available) to pump the water. That way they're using the water to store the energy for use when it's needed. This overcomes the disadvantages of renewables, which can be unreliable.
maybe now (not here, actually), but they've been using pumped storage for decades (here, anyway). It's fine, but not free -
we could use the energy to do all sorts of things. you could haul up a huge concrete weight and use it to drive a generator. you could crack water and make hydrogen to burn when you needed it. they are many ways to store energy without a battery but batteries are evolving very quickly these days and are just going to get better and better.
Yes Virgil Pumped Hydro is a great way of storing energy if the geography permits. A great example is the one in Okinawa, Japan, using pumped seawater up to a mountain Reservoir - en.wikipedia.org/wiki/Okinawa_Yanbaru_Seawater_Pumped_Storage_Power_Station
Fantastic documentary, guys. Very well made. No fluff, no filler, no political tiptoeing: just great reporting. Makes me so happy for the future.
We appreciate your feedback. Thank you for watching!
Lol no political tiptoeing
I needed this after all the negative news from Washington. Thank you.
Chris Michael I agree
vpro documentary I am blind woman and I am a resusable energy marketer. I work hard I can admire other countries that have always really have had this issue. I understand. Thanks for sharing.
Excellent video! I would add one thing... the thought (~ 19:00) that America's problem is that government changes every few years isn't quite complete. It's that campaign finance here is absolutely corrupt. With few exceptions, the elected representatives' campaigns are being primarily funded by big money, and they listen to their donors, not the science, and not the people.
Not Bernie Sanders. His campaign is solely funded by private citizens. Please check him out. He's definitely for phasing out fossil fuels and much more that is good.
Peace
@@selah71 fazing means not affected. Think you meant "phasing". Words matter.
@@colingenge9999
I agree words matter. Thank you very much and the misspell has been corrected.
LJ Adkins I like Bernie and Elizabeth. They both are willing to openly admit that our system is utterly corrupt and useless. Reading Art. I of the Constitution, you see that the ONLY party ANY member of Congress (either House or Senate) is answerable to is their CONSTITUENTS. In other words, the roughly HALF of each day they spend fundraising for their campaign should be considered THEFT from the taxpayers that voted them into office and they should be immediately impeached, if not imprisoned for political fraud/malfeasance. If we knew all the little BS that goes on with our taxes and in our name we would all have heart attacks...chiefly among those would be knowing that HALF of our collected taxes go toward servicing DEBT under the Fed. Reserve system. We pay 6%(!!) interest on the money they don’t even print...which is especially painful because the Fed is owned and run by foreign banking families with our well-being nowhere near the front of their minds. Further, the IRS is a private institution illegally run with NO legal mandate as the Fed. Reserve Act was never properly ratified and a non-apportioned tax on income is unconstitutional.
So, if we are to claw our country back into our own clutches so it can work for US taxpayers... not bankers, lawyers (the BAR is a foreign entity as well, the British Attorney Registry that serves the British Empire), lobbyists and especially not OIL COMPANIES!! The fact that oil companies, oil pipeline companies, refiners, etc. are given huge government subsidies...should be SICKENING to those of us that are NOT wealthy and watch as gas/natural gas prices go up at a much higher rate than the cost per barrel would indicate, quickly rising but slowly falling to bleed us dry every week, year and month. When we drive Shell, BP, Chevron, Mobil, Conoco, etc. out of business it will be a joyous day because it will signify no longer damaging our biosphere by continually adding carbon to our atmosphere! Sorry for the long rant, I truly wish we would take renewable energy seriously in the USA...
After Bernie is elected, create a massive push to repeal Citizens United... if ever there was a "corruption enabling" money train, that is the ultimate. As long as politicians can be bought, there will be little change. The levers of control have been taken away from the average working citizen - the MAJORITY! Remove the corrupt purse strings of Citizens United, and we will return to political representation by the people, for the people; NOT by the corporate elitists.
The most terrible is that Spain do NOT allow solar energy ... Costa del Sol, wth 320 sunny days ... NOT ALLOWED TO INSTALL SOLAR PANELS on private houses ... HORRIBLE!!!
Why?
Hell, we still have, gated communities and homeowner associations, being built with no solar considered or allowed, talk about closed minded. But, Mats, that is most bazaar thing I ever heard, can't understand such idiotacy!
Thanks to spanish government... and this is why the country economics is growing: they are without gov for some months
In Spain the utility companies control the Rajoy government through bribery.
That's because the Spanish government is not stupid, they don't fall for these lies. And you can install solar, you just have to pay your taxes. We all have to pay taxes on oil too, so that is only fair.
Brilliant Documentary! It's re-assured my life-long dream of solar and renewable energy autonomy on micro and macro scales.
Finally it is the dawn of the world's sustainable future, in every sense.
Brilliant Bull Shitary
Bravo! It was very clear from the onset that once the renewable technology proves itself, there will be many converts and champions. So happy to see a corporate banker saying he's excited by the future and having fun. Yes, we are at a turning point. Countries which are ahead in the race to embrace this change are securing their energy resources and therefore economy in the post-fossil fuel world.
Thank you for your positive comment Lajwanti.
This is the best documentary on renewable energy, by far. Thank you!
Thank you very much for uploading these videos with Spanish subtitles.
Thank you for watching Deivid. We are glad to read your comment. :)
Excellent .. You well articulated current state of renewables, these should be self evident to detached observer without even an explanation.
Thank you, highly informative. It shows what people can do when there are no walls.
This is sadly depressing from an American perspective where we have "successfully" succeeded in politicizing science, technology, energy and economics.
Hans Hyde It is not too late!
Totally agree same in the UK. If anyone thinks not then please say why, it will cheer me up a lot.
IF mmcc was actually science, and it was a danger, wouldn't people spend 100k to fix the problem? That's all it would have taking in 1979, a single 100k investment would have resulted in a hydrogen based economy.
IF that is true why are we not running the entire world the way Russia tried to do and china is trying to do now. Even the Muslim religion is trying to dictate to the world how it will live. So if the us is the great satan, why haven't we already taken over the world?
@@roberthicks1612 800 military bases around the world, less than 200 countries
The stats for 2016 show wind supplying 4% and solar supplying 1% and it requires expensive storage to ever get beyond their power factor of 15%. The really big growth has been natural gas, which is also the number one choice to backup renewables.
Good documentary! I like the guy at the end : I delay my retirement with 2 years because Iam having so much fun now ! Good point !
The time has definitely arrived to implement renewable energy projects globally. Identification of storage systems to compliment existing PV tech systems is vital at this point. The shift is upon us.
Amazing video I can't believe there is an island that runs totally off renewable energy and California just essentially through away 190,000 kWh of energy last year. Something has to give soon.
Exceptionally good documentary, explaining the economic and financial facts which I have been trying to explain to people for years. Great stuff. I'm sharing it everywhere.

@@vprodocumentary Have you ever heard of Tyrants fighting wars with battery powered WAR MAKING Hardware.. Make a Documentary on that, if you will.. Who is paying you to produce Videos on this subject matter? Sounds to Me like it's the WEF..
This was very straight forward and informative. A bit bias but good;), thank you for sharing. It motivates more and more to continue studying renewable energy and natural resources.
This is a phenomenal documentary!!! Amazing that I didn't find it before.
I love the part (32:20) with the explanation of using cars to store power for the area. Amazing concept indeed!!!
Does the car owner have to pay to replace the energy drained from his car to supply the houses?
Does the car owner pay for the energy that is being drained from his car to service homes?
Does the car owner have to pay to replace the battery? They are rated by number of cycles.
Nowhere in the world are stock EVs allowed to dump power into a utility grid. It’s another comic book scam.
Thank you......good documentary. Its good to see small communities like El Hierro making this commitment and seeing it work. It gives me hope that the oil industry won't destroy the planet.
@@topraginuyanisi It beats letting the planet burn up.
@@RuleofFive we all should learn to use energy wisely. have you heard of degrowth?
@@topraginuyanisi I have and from what I know it makes sense. The trouble is it terrifies the financial industry or any other growth oriented business so some don’t take it seriously.
@@RuleofFive i normally listen to scientists instead politicians and economists, they say that we will have to degrow in any case, we live in a limited planet. Economists ignore that and politicians trust too much in economists.... i think that we, people, should make that changes that we really need.
@@topraginuyanisi Our problem is massive energy systems make a ton of money for the people that own them. They fight like hell to maintain these systems.
Awesome documentary guys, thanks for making it. A real positive outlook on whats become a rather depressing theme.
A brilliant documentary! It covers pretty much all the economics and politics of renewable versus fossils fueled energy.
Thanks Jenkins Dagba!
@@vprodocumentary For a 3 year old documentary, it is still quite relevant and accurate.
Eye opening, will share, thanks!!
Great, informative video, thank you. There is hope that Solar & Wind Energy will continue to expand.

Great video. I'm sharing with my friends and social media groups. Thank you!!!
Thank you!
But the ways to STORE the energy is still lacking.I use lead acid batteries.I need more of them.My wind turbine is small and works best in the fall and winter.Solar is working during the day and charging my batteries.

That's GREAT news!
Maybe I can use BOTH type,when the time comes.
Thanks for the post!
Dave in Seattle.
you can store energy in any one of a number of ways. they even showed you one in the video (did you watch it?). pump water up hill in windy and sunny days and let it flow down to drive generators. they said in the documentary that on that island, the water was good for 4 days of energy use.
Super interesting, really well-made documentary - I highly enjoyed!
I don't enjoy documentaries that are made by the New World Order. They are responsible for crimes against humanity in 2020. They should be held accountable for their fabricated lies and their man-made viruses that are being used to line their pockets with billions of dollars. Why? Klaus Schwab = Dr. Evil. Shove your sustainable energy and your new green deal that hurts the middle class and helps the one per cent. You are all a bunch of psychopaths. Satan loves you.
@@susan638 You really need to see someone.
@@MalteDegener well that was kind of mean-spirited you don't work for Google do you, if not I'd like to debate you on a few of @Susan's Points I CHALLENGE YOU!
Very important and revealing information. Are there any subtitles for this video? Portuguese?
Part of the low price depends on something around 5 hours of peak power equivalent per day. To a first approximation, if you only have 2.5 hours of peak power per day, the price per kWh would be twice as much.
exactly it can only be done in the desert
Amazing! Renewable energy NOW! This is brilliant! Politicians have no excuses now!
Those stupid politicians persist globally, let's vote them out of power while we can!
The whole Earth needs this.
The ideas at the end are pure genius!
But i don't get why all these companies and investors are not backing up Tesla and other electric companies to extend the market no only on Sedans but on bigger structures that run on electricity rather than oil. Beside i want also the opinion from oil producers about this energy shift
The difference being Tesla/Solar City operating in the US market system where everyone is more concerned about what money they can make in contrast to what benefits can be achieved through societal systems. To do what they are doing in The Netherlands example, data related to energy consumption & production has to be a 2-way street, something that is acceptable to many outside the US, but inside the US, it's a no-go.
jonathan Rachid each bussiness is it's own.
Texas politicians have gotten a ban on retrailing Teslas in Texas. Who says that we dont have the best politicians money can buy? Now, does anybudy want to back my buggy making company?
I can't believe anyone would dislike this video. They must be big oil and gas.
Head scratcher...
I can't believe anyone would believe this STORY.
Because they are lying. Badly. It,s 2 years since the video was made. Their numbers are way off on price..
Oil and Gas companies heavily support solar&wind because thats two is a totally failed technology, and will never be able to supply enough energy to us no matter how much money they wasting on the technology. Thats why German's co2 emission barely shrunk, while in other countries like france just using nuclear with much less co2 emission. Germany failed very-very hard, its time to realize, and restart nuclear research and investments.
It's because the whole story is political bullshit.
The earth's climate always changes. So stop worrying about that, and just develop sound energy technology.
The planet will take care of it's self. ( Even if it has to thin us down to do it. )
Thank you for this incredible documentary.
One more thing! In the State of Missouri we've had for fifty years a power station that pumps water to the top of a hill for energy storage.
Where exactly in Missouri? There are man made dams with generators but they don't pump water back above the dam with solar powered pumps.
27:19 They short-sold the stocks of the competition. That shows pride in their product.
Edit: The host resembles Bill Nein.
Creating a renewable energy economy, done correctly, will be the greatest economic opportunity of this century. Fossil fuel companies' subsidies must be tapered to zero, they must start paying for the megadeaths they are causing (they make opioid mfr look like saints with 110,000 premature deaths in the US alone) and the environmental damage they cause.
"but we rely on fossil fuels for power and plastics" yes, but there is currently little incentive for companies like Exxon to plan for vastly increased supply. They are getting away with murder and yes renewables are close to competitive now. When fossil fuel stops its free ride and a free market for renewables evolves, costs will go down so that fossil fuels will not be competitive.
Consider homeowners collecting solar and storing power in their homes and cars that they can sell back to their neighbors based on bid/ ask pricing. If storage is needed, it will be provided in the most competitive means similar to Uber ride sharing where demand dictates price and small players make it run.
For decades the Pacific Northwest has sold power to California which is bought back at night for low price, used to pump water back into dams so it can be sold the next day to CA. Stored solar using the free market.
Solar energy is toxic in its construction and creates deserts due to extreme land usage. Also inefficient.
OMG, that guy in the Netherlands who is combining solar panels with car batteries is a GENIUS!! What a wonderful idea! I am LOVING this! I wish we did that in the States.
Best batteries to start are golf cart batteries, but that was in the 70's. Tesla uses a battery to store power now. But that's big bucks,
Question : when they give a cost of xx per kWh, does it include recycling of the material, decommissioning of the plant, etc?
I believe not (nobody does, especially not nuclear) but at the same time, oil and gas electricity does not include the cost to "compensate" the CO2 emission, I-am right?
Excellent documentary; uplifting yet down to earth, quite wide-ranging in its analysis.

Awesome, very informative documentary. I have been a big fan of renewable energy for the last 20 years, I new the only reason it was not more advanced and accepted was because of big oil and coal. I am so glad to see this trend moving on a world-wide scale.
FYI - Video poster of this: The video translation in the China portions of this show incorrect wording to what is on the film screen. You may want to fix that. It's only after the speaker returns to English that the screen correctly shows correct for the closed-captioning screen option.
Nice. A topic close to me, energy and the Middle East. Once again, the Middle East is lucky for energy generation making the location ideal for solar energy. The oil companies shouldn't fear renewable energy, oil is essential for manufacturing. All they have to do is reduce volume to keep the profit they are used to.
We just painted a solar energy Manufacturing facility in Toledo Ohio. First solar
Awesome news. Don't forget to pay cost plus 10%. If I don't get my 10% for the widows and orphans and the poor. I'll shut off the sun.
excellent documentary, big thanks!
After solar, ITER kicks in.
Great Documentary! An EYE OPENER!
Spread the word and save this world. Every human being on this planet should be able to live in a clean environment, that includes clean provisions and clean water. We can do this, so start lobbying for what really matters renewable energy. We would be stupid not to do so.
Is there a 2019 update to this? This was released three years ago. Frightening enough for 2016. Where do things stand now?
Its doing great at this time. Please google " PV magazine " for all the latest updates.
@@courierton9217 So grateful.
Where do you get ALL THE LAND needed for all these solar panels ?? HOW MANY BIRDS ARE KILLED?? Where can we grow FOOD FOR PEOPLE ??
You are desperated need for math
I was wondering when the would realize that open sand was worth some cash it you put some shade over it. If the price they are quoting is indeed true, then this IS a game changer. The only question is, can the solar power cover the base load? If it can do that then we have a silver bullet. I still think we need something to replace coal for the really heavy generation needs.
The stabilisation of the energy supply, will be a huge stabilizing factor, for the World as a whole. Think of all the wars, that has been fought over energy. El Hiero is amazing. A great example to be followed.
In the future, they will say, it was a no brainier, solar can bring in 20 times as much energy per hectare, without water, or fertilizer, on agriculturally useless desert land. Electric vehicles cost a tenth as much to power, need a tenth of the maintenance costs, the roaring 20's are back, in the first industrial revolution, they made 5,000 miles of railway tracks in a single decade. In the second industrial revolution, the number of vehicles increased by tenfold in one decade 1915-25, in Australia 25% of the deserts, could produce a trillion tons of liquid hydrogen per year. Then there's LED's, in high rise farming, using reverse osmosis desalination, Australia could, using the same 25% of its deserts, produce all of the world's food requirements, don't say energy and transport can't change in a decade. They did in the second industrial revolution, they did it in half a decade recently, unconventional hydrocarbon production, between 2009 and 2014, crashed energy costs, China, with the world's largest population, changed it's rail transport to high speed 2008-13. Once again, they'll tell you energy and transport can't change, in a decade, but I've just shown you, that they did, in half a decade, only a few years ago.
Roger Reimer the internal combustion engines take far more energy to forge. It’s all steel and the melting point is 2,800 degrees.
And when your done they still burn fossil fuels.
There are only four basic elements in solar panels. Many can be replaced by less rare components.
Thin film solar panels are printed and do not require the heat that silicone does ( silicone is cheap and abundant.)There are millions of panels still working after 30 years as we speak.
The infrastructure for panel installation is aluminum. (700 degrees melting point).
New roofs can be replaced by solar shingles. The petro based composite shingles take huge energy as they are made of petro themselves.
Windmills: The generators have far less components than their generator alternatives & have a fraction of the steel.
The poles that elevate them are less than the building (steel) to house generators at power plants.
There has to be a balance of need versus regeneration of the planet and altering human behaviour. Prioritising correctly so it's not just consume consume. Swapping coal and oil for wind and solar is an improvement of course, but desert can be regenerated. And that land produces. Moving to regeneratives systems will provide fresh water, food, employment and take care of our planet. I would loathe to see fields of solar panels take over the open spaces of the planet; spaces that could be saved from the degradation already caused by human activity, only to be further abused by being paved over.
NUCLEAR POWER will NEVER be outdone by solar or wind... You're stuck in a pipe dream.
@@weatherphobia Is anyone developing 'molten salt' reactors?
@@weatherphobia Solar IS already cheaper than new nuclear plants. if you have reasonable safety. Sure if it is an old plant from the 1970s and runs on wobbly limbs so to speak ..... The people that were damaged by Fukushima are NOT compensated. The risk is not insurable and it would be so costly that the government does not compensate them either. Tepco was saved, yes.
This gives me so much hope for the future.
Then you need a shrink.
me too! 🙂
It stunned me, around 2000, having devoted some 12 years to the pursuit of the possibility of a self sustaining Wind energy system, when I started to
look at the cost of the two essential
parts - The Turbine, and the Alternator, or electrical half- of a "Turbine" i.e. a wind Turbine-Alternator device - TAD.
First I saw that making the Turbine Smaller was Always a cost advantage because the weight (cost) decreased like Volume, but the ammount of wind
" processed" decreased as Area.
This seemed insane ! As one guy said, " we will have them on rings on our
fingers, or on our hat's !? It was not for about a year that I started looking at the costs of various generators/Alternators and noticed that smaller was More cost/ watt. Bingo ! Eureka ! the insanity was cured, and it was soon "obvious" that the lowest Total cost was for sizes where the two halves cost about the same.
When starting out, cost v size is a question that never crossed my mind. It arrived near the End of about 3 designs from which I gained actual watts, and data.
It is a completely unavoidable fact of Any T+A combo. No matter what.
So one must look at these Windfarm "Turbines", and ask oneself, " how do the costs of the T and the Electrical half compare?"
I really cannot believe that their costs are anywhere near equal, but have not attempted to obtain figures, other than these.
From a public meeting at Llandeilo, July/August 2005, I gathered the following:
Cost of proposed farm...153M
Expected annual income ...0.2M
That's over 500 years to regain the energy invested in it, for those not familiar with simple arithmetic.
it does not Have to be like this !.
An annual return of 5-15%? of the energy required to create the system appears possible with a design which does not ignore elementary mathematics, such as Area, and Volume - as does current Gigantic "technology".
A turbine of Twice the diameter, replaces 4 previous, but costs 8 times as much for materials (Area becomes 2 squared, Volume, 2 cubed x what it was).
The One Alternator, however, (to replace the 4) costs only about Twice as much as any one of them. So the A-bill halves if we double the diameter of the "TAD"s, and use 1/4 as many, i.e.same size "farm", whilst the T-bill Doubles.
The Total cost, of T+A, can be seen to be minimum for sizes where the T and the A cost about the same. Now by some remarkable piece of Cosmic serendipity ?, that size is neither a mile across - nor an inch across - but just happens to be a very convenient, man handleable, 0.5 to 1.5? m across. It is hard to justify building them much outside of this range, on economic grounds.
Also, the bigger the diameter, the wider is the range of wind speeds from top to bottom, ("wind shear"), so it is not possible for the Pitch to accomodate all of these, making a mockery of accuracy of the pitch setting, and aerodynamic perfection of the wing !
Secondly there are Two possible modes of operation.
a) Constant Revs/min and vary the pitch of the "blades" (- which need to be Wings, of course !)
b) Keep the Pitch Constant , and adjust the load so that the Rotor turns at a speed correct for the air passing through.
i.e.
2.Pi.r.n (the speed of the piece of Wing at some radius, r) needs to be = w.Tan(P) (in both systems).
w is windspeed.
n is rev/second P is pitch at radius r, measured so that 0 degrees = Edgeways-on to the wind.
Now although the torque (T) will be the sum of all the pushes x all the radii along the wing, I will consider just one bit of the wing. This is ok since it will affect only the Size, Magnitude, of the "answer", and we are concerned only with the Shape of the expression, or "answer", wrt windspeed.
If we look at the first one, we can get an expression for power into shaft, from each little length of wing.
i.e. 2.Pi.r.n. x useful component of that bit of wing's "lift".
n is (rev/sec) which is constant. Call it 1 unit.
Leaving out constants for the above reason, because they don't affect the shape, but simply confuse,
The speed of the wing is fixed at 1 unit
From pythagoras triangle Wingspeed (1) windspeed (w) speed over wing - hypotenuse - is
Sqrt(1 + w^2)
So lift force is (1 + w^2)
and its useful component - in direction of travel of wing - is
Lift.Cos(p) which is (1 + w^2) . w/Sqrt(1 + w^2)
do the power put into the slternator shaft will be 1 x this, for each bit of wing, will vary with windspeed in accordance with the expression,
P = w.Sqrt(1 + w^2)
At low winds, w is a lot less than the 1 of the wingspeed, so the relationship is pretty much a direct, linear, "twice the windspeed, twice the power into the shaft", type/variety. It rises a little above "straight", at high winds, towards a w^2 curve.
Now taking the other posibility, the airspeed over any bit of wing will be proportional to w, since although both wing and wind speeds double if the wind doubles, the two add by Pythagoras, being at rt angles.
Lift (the useful) force is proportional to w^2, and therefore so is the torque applied to the shaft. Since power is (2.Pi) x revs x torque (push x radius at which the push is applied) the power transmitted by the shaft is proportional to w^3, i.e. k times the wind gives k^3 times the power, e.g. Twice the wind, 8 times the power into shaft.
So this is obviously the system to adopt if at all possible. And - unless you have your alternator running at constant speed - 50 Hz synchronous - like "windfarms", it is perfectly possible.
N.B. !
If however you DO have the alternator running at fixed speed, and you decide to use gearing to increase the rotor speed - thereby moving towards operation mode 2) - the extra Torque becomes proportional to w^2, instead of w, this creates w^2 current in the copper, and since heating is proportional to current^2, the heating of the copper in the alternator is prop.to w^4 - which causes it to cut-out - or burn-out - during a heavy gust, or contunuous high winds.
So the Aternator Cannot be run synchronous for a TAD to have any chance of paying for itself in a lifetime.
Next there is the fact that the bigger the Rotor, the greater difference in wind speeds over the entire swept area
This renders any "aero-precision" in its manufacture a total waste of effort !!!
Meanwhile, the tiny hubs serve only to create a "materials/engineering" problem !!
So, to sumarize,
1) There exists a SIZE giving lowest cost/kW-hr
2) The TAD needs to run at windspeed, not fixed speed, to make full use of the energy available in any given wind.
There is also the consideration of "Churning", or "turbulence" caused by pseudo-random airflow through a "helicopter on its side " sort of device. "Air friction". This can be eliminated in the turbine itself by carefully designed, matching, pre, and post-fan "Ducts".
I can send the design for this to anyone interested, so that they can check the reasoning. I can vouch that the prototype performs as hoped/expected. It delivers a full 50% of the total k.e. of the wind as useable energy.
I kid you not, it reaches 50 degrees Celsius here in Abu Dhabi. About time somebody came to utilize that :)
This doc was good but it would have been really helped by having more segments on real-world examples like Hierro, Utrecht, etc. --and not just at the end of the film.
The problem is the battery and not about the capability of the solar panel.
Being solved now
Not a problem as far as non mobile battery storage is concerned it is already here. Flow batteries are cheap last 25 yrs & can take as much current as you can throw at it.
And if you were paying attention the e-car revolution can second as a backup for whole neighborhoods.
The rest of the world is. Quickly becoming independent. Your argument is obsolete as of 2012.
Not to mention the brake through on mobile batteries already proven in the lab and in prototypes.
Dana Putnam
You're coming off sounding like a real piece of shit. That's no way to win people over. We don't need assholes on our side. The battery is the problem and has always been the problem.
alex tworkowski not sure if you replied to the intended person as your comment does not seem relevant to my own. I provided you with info and you responded with the same statement from your post.
Also I do not use profanity or use derogatory commentary nor do I result to name calling. These discussions are technical and intellectual and I am here to share info or learn info.
There is a lot of misinformation or obsolete info. on the topic of renewables. If you expect to inform an individual please respond the the data and do not personally attack the person just their info.
You have not provided an argument or a discussion regarding this topic or my contribution.
Are you an intellectual? No evidence has been provided for that determination other than the observation of the above mentioned poor behaviour!
P.s. I have a number of comments on this video and have received a large number of likes regarding them!
The batteries are the most expensive
It’s now or never to switch to alternative, sustainable and renewable energy. Indeed, great plan and achievement from the Chinese that will change everything in a positive way; giving mother Earth a chance to thrive and scale up towards a cleaner and safer future. Thank you for this documentary, very much appreciated and this switch to renewable affordable energy is so urgently necessary in our escalating polluted world.
Be practicable, Everyone.. Solar and Wind Energy can NEVER compete with Fossil Energy, no matter how cheap it becomes.. The sun never shines on one place on the EARTH 50% of the time.. Forget about the wind.. DO YOU know how much Carbon Energy is required to manufacture Solar and Wind Hardware? The only people who supports this kind of energy are the people who stand to make money from this.. You never hear about how much Carbon is produced in the Manufacture of this Hardware.. We would have been better off it Hitler would have won WWII.. Energy should be FREE to every inhabitant on the Face of the Earth Do you know how much Produce can be grown on a Field full of SOLAR Panels? Why do They use Females to "VOICE OVER" Video Clips of PRO Natural Energy Production??
GREAT foresight guys, it is now finally well under way
25:27 vertical video recorder spotted.
Bad video camera operator!
Really? After watching this video, that's all you have to say about it???
No, look at what he does at 26:51 - that will be one fucked up home video, ladies! (´◉◞౪◟◉)
@@PenisMcWhirtar yep i was thinking the same thing... there idiots always recording everything. not able to grasp the concept of whats being said in the moment...
Probably in charge of multi-million budgets and hundreds om employees too - scary LOL!!!
Thank you for the documentary, really informative for our future project.
That's it. I'm moving to El Hierro. What a cool place!
Where do they consider the cost of batteries to serve base load electricity
Thank you!!!
fantastic documentary! feeling inspired and hopeful for the world
Highly inspirational. The world can change respecting the weather condition and deal with them to create progress.
A thought on roof panels. If the roof is 16' ridge to drip, 16' panels that hook together is the best way to cover it. Frame the roof and then use panels that provide roof decking, roofing and solar all in one.
I would like that New York City, where I live, to have the same planning system as the city in Netherlands...would be amazing...
New York may be too dense in infrastructure and population to support large, sprawling fields of solar panels. You could have it on your roof, maybe, but that's about it.
Rising Boner I don't know but seems in this city everything in large scale cannot be done properly...many people have interest that this city not change
YYYYYYYYYYYYYYYYYYO!The sides of the buildings,the roads,the electric poles themselves etc,etc.
winston maraj Ghetosss feeling there..
say what?
very cool movie! thank you :-)
This documentary needs updaing every year. I get my solar energy from Ecotrocity a green Energy company in the UK.
Just AMAZING !!! Very interesting documentary.

"I have a feeling that smog levels have exploded the past few years"
me: YA' THINK?
What was your first clue?
The goverments been lieing about pullution all these years and now they want to tell you still to this day they don't belive pullution or the ice isn't melting don't belive a fucking thing they tell you there all liers
Australians just voted to approve the worlds largest coalmine and ship it off a port in the Great Barrier Reef. I don't have much hope now that we can save anything.
Russell Gillick
Wow:( I can’t believe an apparently forward thinking country like Australia would do that.
Reminds me of the cynical laugh my aussie ex-girlfriend gave when we passed a car with "Queensland - The Smart State"-plates about twelve years ago. My condolences for your politicians!
Like many other nations Australia has great potential in many fields for Pro-activeness in development - advancing ahead being a great example . We could have one of the largest Solar Farms in Simpson Desert Central Western Australia . Truly with Four of the worlds best banks, you’d think they’d see a great opportunity of Investment .👀.
Yeah. You r right bro. I will not agree on that 'we cannot save anything'. Think in OPTIMISTIC way rather than PESSIMISTIC,we will difinetly achieve SUSTAINABLE DEVELOPMENT.
I got on board the solar wagon 10yrs ago with a modest 2kw array on my roof. Since then It has produced nearly 25,000kwh of clean power reducing my energy cost to a mere $150-$200 yr av. With battery technology improving hand over fist and the cost falling almost audibly, I don't understand why everyone isn't on it! . ..Love the idea of using a car battery for domestic storage!
2019 where are we??
excellent documentary
That was great. Thanks.
Sana sa Pinas ganyan din dumami solar and wind para clean energy. Di natin kailangan ng factories or coal.
offshore wind far away you can't see it. but also put in where low or shallow impassable shipping routes maybe!
I can't stop listening to this docu.
Have you seen that Germany just managed to create 85% of its energy from renewables?
This is happening!
No I havent.But is that figure a real one or a play with numbers?

Look for yourself!
Hold on! Robin Berg of the netherlands claims " some cars have a range of 400to 500 km. ? Please state which cars you are speaking of.
The current EPA ratings for Tesla Model S: Standard Range 460 km, Long Range 600 km.
Mooi al die duurzame energie, beter voor het klimaat en voor de planeet en dus voor iedereen. Alleen spijtig dat de resultaten ervan voor een groot deel teniet gedaan worden door ons economisch systeem dat toelaat, of beter gezegd vereist dat nog steeds enorme hoeveelheden bos vernielt wordt en zoveel nutteloos transport oplegt. Bijvoorbeeld voeding als vis, vlees en groenten in een land geproduceerd om duizenden kilometers verder geconsumeerd te worden. Of erger nog, voeding wordt duizenden kilometers ver getransporteerd om goedkoop bewerkt te worden en dan weer teruggebracht naar de plaats van oorsprong. Het argument dat alle overbodig transport weghalen teveel arbeidsplaatsen zou kosten is een vals argument, want het volstaat dan om het aantal werkdagen te verminderen om weer het aantal arbeidsplaatsen op peil te brengen. Economisch niet haalbaar? Toch wel indien we naar een economisch model gaan zonder winstbejag. Dit is mogelijk als de meerderheid van de bevolking dit wil, en minder werken voor gelijk of zelf meer loon daar kan toch niemand op tegen zijn.
Wat in de documentaire getoond wordt is als twee stappen vooruit doen en een achteruit.
Learn many new ideas from this video....thanks so much

We would be foolish to believe that our man-made waste products (smog, Co2, pollution etc..) have no consequences. It makes sense that we look and invest in new cleaner technologies, energy sources and plastic alternatives. We can do better.
Judging by the rash of bankruptcies across the coal industry, we've already reached the tipping point. As the Saudi Minister for oil said when he flagged the end of oil in 2000, "The stone age didn't end because we ran out of stone."
@MoralSingularity Not a lot of coal there and you might like to think about all the ecosystems killed by the fossil fuel industry generally and the massive death toll globally from pollution.
The German guy at the end is so upset :-D
If he seems upset. its because he cant understand why larger countries have not bought the vision🇯🇲🇯🇲🇯🇲
he clearly is not upset... if anything he looks rather desperate
Doesn't seem upset to me.
In part we have the greed of the fossil fuel industry to thank for making this possible.
This is going to change my life. I always wanted to work on sustainability and now it is going to pay also.
The final magic bullet for insuring large scale use of renewable energy is mass energy storage. Scientists and grid engineers have really struggled with with part of the renewable energy and it looks like the technology has finally maturing.
Phillip Mulligan it is and it's very exciting :)
This is so encouraging! It brightens my day for sure!
However, just a little precision: the production in China is highly subsidized since the gov is driving and paying for research and dev. But I don't care if it works!
lets go!!! future will be great!
I fixed it. Removed caption feature. This video is timely and provides an accurate assessment of the current sustainable energy issues.
Thank you UAE.
Thank you Masdar.
