Floating wind turbines: Offshore energy's secret weapon

One small twist could revolutionize the offshore wind turbines: making them float. Offshore energy’s major problem is that they can only be built in shallow water, but most of the wind in the world’s coastal regions blow across deep water territory. Can floating wind farms solve this?

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 floating wind turbines will be part of our future energy production?

With 70% of earth's surface covered with ocean and the majority of human civilization living along ocean coasts, it makes perfect sense to be giant, floating wind turbines offshore and cover EVERY roof, parking lot, and dead space, with solar panels. I think we'll get to a single, pontoon-style, floating pier with one cable anchored to the sea floor with the power cable attached to it.

1:58 ships don't displace more water as they weigh, they displace exactly as much water as they weigh. They usually could displace more water, but they only do when other nonhorizontal forces apply.

The fact that they can be assembled in the port is in my opinion huge. The amount of technology needed right now to assemble wind turbines out at see, using cranes that have to be stable, and massive boats securing them too the seabed. I can very well see how assembling these on or close to land and towing them to their destination could be a huge cost saving in the long run.

the next electricity revolution needs to happen with transmission cables and power lines. we can generate as much power as we want, but so much gets lost in the lines that we need to make a lot more power than we need.

Brilliant video! I hope you guys can do an another follow up vid on this every once in a while. I also hope that you can dive even deeper in to the research on the environmental impact floating offshore wind could have.

I truly believe that floating offshore wind is the way to go, but I am a bit worried that this could have a negative impact on marine animals, especially marine mammals like whales and so on. Sharing information about this would be very important and useful for the further development of this technology. Hope you guys can dive in to it.

Keep up the good work!

It would be funny to care about the impact of turbines that don't dump anything in the water but not to care for fish farms in water ...
Cause ... there's ton of fish farms in the sea ...
Go to wind power ! More bebe !

[nathanngumi]

Great introduction to floating wind turbines! This is a game changer for wind energy harnessing. Yes, your craftsmanship is good!

[anueyiagumichael]

Yes, more research needs to be done. It is more feasible than onshore wind turbines for places with high population density.

[harrykekgmail]

good and educational. easy to understand. thanks

[KougaJ]

4:11 not just to keep them anchored in place. Also to get the energy from them to land. That's what they're there for, after all. :)

[tomkelly]

I think this is a good field of study and investment although I think it comes far behind powering up unpowered water dams, using dams as batteries for other power sources, public and mass transportation systems like trains and subways, hydrogen blimps, etc.

[kino_cinante]

I always thought they should use a few flywheels to stabilize floating wind turbines. It would also act as a battery storage system.

[lucianolizana]

I really enjoyed this Vox-like video format! much easy to consume and enjoy

[senthilkumarnu]

Good explanation with the use of bottle..❤

[Amir-jnmo]

how do they transfer energy back to the land grid? I wish this was discussed in the video.

[UdaySingh-xnfp]

his natural presentation skills are on another level

[drakemia]

We just get better and better at wind turbines.

[adrienbeauduin]

I think those would be a great addition to existing renewables, we just need political will, and maybe energy companies could invest their record profits from oil and gas into such clean technologies. They’re always complaining that they need governments handouts to go green, yet they mostly give money away to CEOs and shareholders whenever they make more money… or just sue them like they did for tobacco companies and invest the reparations in clean energy

[macnet]

I was hoping you would mention the floating wind farm in the north of Portugal. It's a pioneering project
