Is offshore wind the energy of the future?

Offshore wind farms solve one of renewable energy’s biggest problems: unreliability. With wind almost always blowing on sea, there is no lack of power. But the technology is struggling with a bunch of other hurdles.

We're destroying our environment at an alarming rate. But it doesn't need to be this way. Our new channel Planet A explores the shift towards an eco-friendly world — and challenges our ideas about what dealing with climate change means. We look at the big and the small: What we can do and how the system needs to change. Every Friday we'll take a truly global look at how to get us out of this mess.

Do you think offshore wind is the solution to our energy needs?

[Ikbeneengeit]

Two seamen and 100kg of lubricants... Gonna be a fun ride 🤣

[DeutscheWindtechnik]

Great insight, great video! It was a pleasure having you on board, Kai!
Who could imagine to work with us offshore and support the renewables?

[killerrabbit]

German public:
We need clean energy!
German government:
Ok, we’ll build air turbines and a new grid
German public:
No you don’t !

[orengordon]

He clearly thought he was going to climb the turbine😂

Electricity from wind power currently has the lowest carbon footprint from a cradle to use analysis. For comparison, it takes ~10 grams of CO2/kWh from wind vs. ~40 g CO2/kWh from solar, ~450-600 g CO2/kWh from gas turbines and >~1, 000 g CO2/kWh from coal. End of life waste is a potential concern and many stakeholders are already investing in WT blade recycling. On average, WTs live for ~20 years with minimal delays or downtime. There is huge amount of energy that we can harvest from blowing winds. The energy is indeed renewable not only because natural wind blows all the time, but the materials used to harness this technology is recycable in adjacent supply chains. Ongoing work is underway to solve this technoeconomic problem. Short answer: Plenty of potential to decarbonize our grids but can't be used alone.

Superconducting cables could be the solution for transporting a lot of energy. In Munich, a 12 km cable is already in service and in China, a 2400 km cable is planned. High voltage transmission lines have got the problem of resistance from local residences. Often, the resistance gets broken if the cables are underground. Superconducting cables are always underground cables.

Good timing. We were having a project presentation about clean energy😭 thank you. I never knew about this till now.

This video raises an issue that will continue to hamper environmentally friendly renewable energy efforts: people gravitate toward one aspect of the issue, dig in their heels, and refuse to listen to anything other than best case scenarios. This offshore wind turbine technology could already be exploding, but those who don’t want any impact whatsoever on the marine environment are blocking it. Unrealistic, myopic, and — ultimately — destructive thinking; can’t go “carbon neutral” without some sort of trade-off. Another obstacle is the same government apparatus held up in these videos as positive forces for change: They take so long to act meaningfully, and place so many restrictions on energy pioneers(sometimes involving their own issues with corruption/lobbying), that countries such as Germany continue relying on Putin for resources they could be generating themselves (with less negative impact all around)

Offshore is definitely the future unless fusion actually becomes feasible. More people live near coasts than they do deserts and other sun rich areas and oceanic winds are far more consistent AND stronger.

Im new to wind turbine offshore today, this is the 2nd video i watched regarding the topic (the first one was from interesting engineering) and i like this video. very good presentation and and charismatic german presenter with good english :)

Even the electrician confuses MW and MWh and DW confuses kWh with "kW/h", sad 😢

[Keksmania]

We also need cheap energy storage to use renewables to their full potential

[LooseNut]

Well done Kai and DW. Quite informative.

[WIACZO]

Really proud of the UK as they are an absolute leader in the ofshore windfarm technology. Hornsea One is currently the biggest - 1200MW, 11 times bigger than the farm shown in this video. And UK is building Hornsea Two and Three (1200MW each)! Also, Doggerbank A, B and C - another 3600MW. And Sophia Ofshore: 1400MW! Lots of massive ofshore projects are in the pipeline for the UK!

In few remaining months of the 2021 the following should complete: Moray East (950MW) and Triton Knoll (855MW).

Those floating turbines are an amazing feat of engineering.

[johnwayne]

Great video and totally shocking to discover the incredible madness of sea windfarms.

[ryanbrimson]

Great video! Wind, nuclear fission, tidal and fusion if we can manage it I don’t doubt will have massive positive impacts if we start using them as our main sources of energy

[MrYngram]

6:44 Hey, DW! Don't you know that energy measures in kW*h not in kW/h.
And most probbly there is an error. Offshore wind power cost around 70 euro per MWh or 7cents per kWh.
