https://www.renewableenergyworld.com/articles/2018/04/scottland-breaks-offshore-wind-records-with-powerful-turbines-and-innovative-foundations.html

According to Vattenfall, a Swedish government owned power company, Scotland has achieved two offshore wind industry firsts in the past two weeks. First, on Monday April 9th, they announced that they had installed the world's most powerful single wind turbine. The turbine is 191 meters high and the nacelle itself is larger than the London Eye. One rotation of the turbine blades can power the average UK home for a day. It is the first of 11 turbines planned for the Aberdeen Offshore Wind Farm.

Scotland is also the site of the use of an innovative new foundation, called a Suction Bucket, which appears to be an inverted bucket or saucepan shaped anchor that is sunk to the ocean bed then the seawater is siphoned out, making it settle downwards until it is level with the sea floor.

Thanks progpen.

The turbine is huge - a great idea for these windy climates.
I saw a plan a while ago, which gave some figures.

A solar farm just a few miles square in the middle of the Arizona desert could produce enough power for the whole of North America. Similarly, a few square miles in the Sahara (where no-one lives and no-one even visits currently) would be enough to serve Africa and Europe.
Each large land-mass (The far east, Australia,South America, Western Asia) has a similar desert region which would not affect any residents.
The area needed to produce enough solar power for everyone is TINY - "a few square miles" was not an exaggeration - especially if they are interlinked, with power for the USA coming from Africa and Asia during the USA night, and being returned later in the day.
We - in the upper latitudes where there is not so much sun - have wind and waves and water. In Iceland and some other countries there are geothermal sources.

As new techniques and new materials appear, the efficiency of power production increases weekly.

****************
I like the other idea.
Stick your floating bases to the sea-floor using suction-cups!

Drag0, I've been a proponent of solar and wind for as long as there has been either one (sometimes it feels like it's been that long). In the US, we need to move away from centralized energy production and move to siloed microgrids. Each community (neighborhood, town, district) should have its own grid using a good mix of solar, wind, geothermal, biomass, hydro and whatever other options are available to the community. This will make it more difficult for hackers and saboteurs to do damage on a large scale. It will also ensure that each community is using locally produced energy (energy loss over long distance lines is still a major inefficiency in the US grid). It will make it easier to keep grids up to date and ensure that local communities are paying fair prices for their energy because those communities control their own production and transmission. One of the major problems with the US grid is that the producers and transmission infrastructure owners have become accustomed to the status quo and have held the US back for decades.

Thanks for the info, Proggy and Drago. Very interesting what a few square miles could do. And if it is in the middle of nowhere, there could be no NIMBYism.

This is a good example of what can be achieved for climate change innovations.

Digression - Proggy, do you think we can count on NASA's science re climate change any more with Jim Bridenstein overseeing it? He's anti-climate change and lacks the scientific expertise according to sources, but Repubs put him in anyhow.

Hope, funding for the research is being diverted so it's a bit up in the air how NASA or NOAA or the other agencies are going to handle the research and reporting. Most likely there will need to be more leadership from Europe and Asia to pick up any slack. We already know that the European climate modeling software is more advanced (or just more accurate) than most/all of the US systems. NASA and the other agencies will still provide what they can because the people themselves understand the value of what they do. It's just that they are now working around the executive level "leadership" instead of with it.

Thanks, Proggy. Makes me feel a little better with that viewpoint.

I just re-found the map from the article I referred to in the first post.

I love seeing the visuals like this. It just re-enforces the fact that solar, wind, hydro, geotherm, etc. are entirely capable of replacing fossil and nuclear. As long as we don't put all of our eggs in one basket. As long as we diversify as well as break up production and transmission so each area is supplied by production that makes sense for them.

One thing I notice about Africa in the visual is that it shows their current energy requirements. If we look at this visual in another 20 years it will look very different for the continent because there are several microgrid projects in the works now that can significantly affect production and commerce regionally. The projects are proof of concept deployments that show that regions and even villages can be energy independent and support business and manufacturing energy needs. Once these projects are able to take off, I think we will see the continent become a major player in global manufacturing and production.
