So this is pretty freaking cool. The picture feels like something out of a sci-fi novel.Over 15 miles from the coast of Scotland, a wind power project could foreshadow a major part of our clean-energy future. Hywind Scotland, situated in Buchan Deep, is the world's first floating wind farm, with its five six-megawatt turbines now generating electricity. On shore, a one-megawatt-hour lithium battery also helps smooth its potentially erratic supply of electricity to the grid.
Floating wind farms far out at sea hold a lot of promise for future energy generation. A recent analysis showed that they operate more efficiently than those on land or close to the coast, to the extent that three million square kilometers of floating wind turbines could supply the entire world's current energy demand. It's also a concept that's catching on elsewhere, with a scheme similar to the Scottish project under consideration in California.
I imagine floating helps a lot with that, move with the waves don't fight them.
Btw, this is pretty cool.Originally Posted by frickfrock999

Nothing that lights and a foghorn couldn't fix or that the human brain can't adapt to their existence. See/hear them, avoid. Like any obstacle. The coast, itself, is more treacherous.Originally Posted by azanimefan
15 miles out to sea means international waters I believe, which means these things are operating without oversight, safety regulation or taxation.
I can't imagine the navigation hazard these things are. Imagine if these become popular all the ships drifting into them.
They probably won't put them in shipping lanes.
The Convention on the High Seas was replaced by United Nations Convention on the Law of the Sea, signed in 1982, which recognized Exclusive Economic Zones extending 200 nautical miles from the baseline, where coastal States have sovereign rights to the water column and sea floor as well as the natural resources found there.
It looks like it's only effective (profitable) because the government is paying a subsidy of 3x the worth of the electricity it can generate - without paying 4 times the going rate for electricity (which is relatively high in the UK anyway?) it wouldn't exist. I should think they'll only be selling them to countries that are struggling to meet their agreed "green energy" quotas.

$263 million for 30 megawatts of installed capacity... Installed capacity and production are seldom 1:1...The sticking point, for now at least, is cost. Bloomberg reports that the Buchan Deep project cost a total of $263 million to complete. It currently receives $185 per megawatt-hour of subsidies from the British government, on top of the $65 per megawatt-hour it earns for the wholesale price of the electricity it creates. In other words, it's damned expensive.
Statoil says that it hopes floating wind farms could produce energy for between $50 and $70 per megawatt-hour by 2030. That's terribly ambitious-but if it manages the feat, expect to see more wind turbines popping up in the middle of the ocean before long.
LoL ! Just as well that the region is just about dry of oil now....
The British Isles (which aren't a continent, btw; the power is being sent to Scotland) have limited fuel reserves and probably have to import much of their fuel, which runs the cost way up. It also makes them vulnerable to shortages should their overseas supply of fuel be blocked for whatever reason. The wind farm harvests energy from a source that will most likely always be available, despite climate change, unlike some land based wind farms (look at the wind farms around Palm Springs; they have been idle most of the time for over a decade because the stiff winds that used to blow through there are pretty much gone). And, unlike land based wind farms, these wind farms to not eat up real estate and are less likely to kill birds. Cost is pretty much moot when the alternative is inadequate to no power.
submarine power cable, as for how much it costs to lay down, definitely more than underground power cables but not much.
They didn't use these before because during the 70's, oil boomed in the NE of Scotland, ever since then, the big oil companies have been sucking as much money as they could out of the North Sea. From time to time, there is a crash, but they always recovered. The lifestyle of these oil tycoons in the NE is absurd. Also, A LOT of this money was poorly managed, and on top of that, most of it does not go back into the governments hands, but rather, big private international corps like Total, BP, Shell etc. Even the UK government admitted they poorly managed it. Can't find the article but it was posted in July or August this year.Originally Posted by JackCY
The cable costs and total costs must be quite crazy. Why weren't they using these natural resources before... costs, that's why. For many countries such locations aren't available and nuclear power is the go to. Solar and wind are neat but not reliable enough and quite location dependent.
