This has come in handy with today's opposition announcement of a half baked nuclear plan. Why can't we get a live stream fact check footnote if they are selling the Australian public garbage?

BREAKING: "Clean Energy" Engineer calls greatest threat to "renewables" grift in Australia..."dumb" Note: No "totally vested interests" were harmed in the making of this agitprop.

Good luck getting Texas to share or connect its stupid grid to anyone else…

great vid, but the environmental cost of batteries must be factored in, as per the environmental cost of UHVDC. all those raw materials and manufacturing don't come cheap environmentally or energy wise.

Hello rosie.great job.i have a question please.wich type of iron ore that work with this new process.pellet,lump,powder or low grade...?thanks a lot.

5:05 isn't it the crucial part to tell that in order to get drag force in such angle so it's component produce tangential force (and therefore output torque of turbine) that blades need to be shaped in such way? Tear shape makes this possible but I see no way this could work if it had rectangle or circle shape

You just lied, solar and wind energy is the most expensive way to generate electricity!

Rosie, Could you please explain how we convert Spodumene into Lithium Hydroxide? Is it possible to produce Spodumene to lithium carbonate and used in LFP batteries? Thanks heaps

Sounds rather complex and needing lots of resources to build them - seems to require lots of infrastructure to export the electricity to land. Are they really cost effective? And I question how environmentally friendly to marine life?

You know, a long time ago EVs and ICEs used to live along, then EVs disappeared and ICEs prevailed...this is natural selection and it will happen again because reality and physics are stronger than lies and political mandates.

Hey Rosie! You are awesome, thanks for the amazing video!

Why? Because it’s the right thing to do. Why isn’t the west? Because big oil, big finance, big industry, big capitalism, big politics, … can’t find a way to profit from it (yet).

So offshore wind power cost up to twice the onshore cost per kWh......in other words , without government mandates and subsidies, these facilities would never be built in a free economy!

This woman admits she has a vested interest in renewables. These turbines are futile for the climate and horrific for power bills but great for investors !

This woman doesn't have practical knowledge and is selling theoretical ideas. Marine cables are limited by the capacity of power it can carry and there is no way it can be made economically viable. Any electrician can tell that! Also UHVDC would be used and not HVDC for such distance.

UK selling its electricity to other countries, whilst for the longest time we paid 40p/kwh, even now it's still 22p, when before covid it was 11p...

The engineering stuff is good for the tech nerds but most of us are wanting the bottom line on the economic factors with respect to renewables replacing fossil fuels completely. Is offshore wind power going to be the major replacement for the current fossil fuel component of electrical energy generation?

1 kg of coal runs a washing machine from 6 hours. Available 24/7 1 kg of oil runs a washing machine for 9 hours. Available 24/7 1 kg of renewables runs a washing machine for less than 1 hour. Available only when the wind is blowing and the sun is shinning. Nominally 30% of the time in Australia. 1 kg of Uranium runs a washing machine for 2000 years. Available 24/7. WARNING - The washing machine may not last 2000 years. I wonder which energy source makes sense.

Also like other Chinese megaprojects, designed with the core goal of safety in mind, it could provide a Plan B to somewhat get rid of the dependence on imported fossil fuels.

UHV transmission and energy storage devices are not in conflict; in fact they always appear as twins. There are hundreds of pumped storage plants under construction in China, along with various other forms of energy storage centers.

As a Chinese I'm not sure if I'm right or not, as far as I know for example, most of the electric power companies in the US are divided by states and there are too many of them, so it's difficult for them to peak the power resources between different states, and the power equipments are aging.However, China's power system is completely deployed and peaked by the national power grid in general.This makes the entire country's power grid run very efficiently.

It will make sense if you start selling electricity to other countries.

Probably because they don't have to negotiate contracts, they say you WILL build this for this price.

Hi Rosie, Yesterday the ABC ran a "Offshore wind zone for Illawarra coast given green light" article. Thought you would like to know. Cheers.

Very informative Thank you!

Good luck with this take

That's a lot of research

Could HVDC cables be manufactured on the ship laying the cable? Just keep the ship supplied with the materials it needs.

When the battle between Edison and Westinghouse was taking place with Tesla also involved over the future of electricity and whether AC or DC would end up being used for power transmission. The technology to create and handle Ultra High Voltage DC did not exist at that point in time. But with the move to renewable energy UHVDC does make more sense but with the ability to split a line and use 240 Volt and also run three phase on the same transmission system traditional High Voltage AC power transmission is still the king with current manufacturing equipment set up for traditional power HVAC transmission. I still don't think UHVDC will replace High Voltage AC power transmission anytime soon. 😎🇦🇺

The diagram of china being a cable octopus demonstrates the flaw in thinking it would give china control. Why would it make sense for a cable to go around the Cape of Good Hope south of Africa to Argentina? It wouldn't, there would be a cable from West Africa, which already suffers from a lack of electrification, to Brazil, a stretch of ocean shorter than the width of Brazil. China's policy of mutual development generally gives both cooperative ownership and local control over the overseas infrastructure projects China finances

I wonder if aluminum bronze is a good high voltage conductor option, it has very good corrosion resistance and high tensile strength as well as being an excellent conductor

what happens when a submerged hvdc cable gets cut? last time I checked salt water is a pretty good conductor.

Hi Rosie. Can you talk slower? My brain appreciates an occasional pause so that I can absorb all of that wonderful tech loveliness you're pouring forth. But boy, what a pace! 😊 My head hurts after a few minutes.

awesome content, put me in a happy mood for the day even!

dont look at the data. look what happened today.

I don't know who is watching the NEM graphs, but you are wrong. Victoria had no sun or wind and no one had wind there was no way that we could have ........I give up. I have been watching the NEM for some time

China have excessive power.in the west...that need.to transfer to the east...😊😅

Well global politics aside, it can only be a positive for trying to reduce global warming.

A lot of the tech in those turbines is cheaper because it was stolen from European companies. Some have even been found running pirated software by engineers called to consult and inspect them.

Yes but we paid for it , all the wind turbines are built with carbon offset credits and un grants and yet 5he biggest polluter responsible for 58% of the world’s harmful emissions won’t do a thing about it locally till 200 once they have effectively used all of china’s domestic coal

That’s really interesting thank you. 😊

Hi Rosie, in the last couple of days Deutsche Welle News Ukraine covered a story on the strategic move to solar+ batteries in Ukraine with a goal of making an "unbreakable power grid" through decentralised generation. The national and local governments are incentivising solar uptake for critical infrastructure like hospitals but also highrise apartment buildings to communities to individual homes. Also over 300 grid scale solar farms are being built. Solar+battery build out may be the fastest renewable uptake in history in my opinion. It was in Ukrainian so I had to use a translation app.

I'd be careful about the term 'South China Seas'. There's a major controversy and a bit of a tepid (not cold or hot) conflict going on there.

Excellent video!! Using excess solar/wind electricity to split water & store energy as a buffer is the smoothing curve answer.

0:04 Where are the US and India on this chart. Do they have so much space on land that they do not need offshore wind?

0:04 how can Denmark even be seen on this chart. They have a population of ~6 milion out of 8000 milion people. That is <0.1% of all people.

I say build stuff out of them.

Shipping electricity over the ocean would be a highly vulnerable system. Good in theory, but not in practice.

It's a German issue. ..or would be, if we weren't part of the world's biggest machine, the European power grid, and if this/our Europe wasn't surrounded by windy seas.

Send this to the Libs.
