The World's Largest Offshore Wind Farm is Nearly Complete. It Can Power 1 Million Homes (cnn.com) 334

The world's largest offshore wind farm is taking shape off the east coast of Britain, a landmark project that demonstrates one way to combat climate change at scale. From a report: Located 120 kilometers (75 miles) off England's Yorkshire coast, Hornsea One will produce enough energy to supply 1 million UK homes with clean electricity when it is completed in 2020. The project spans an area that's bigger than the Maldives or Malta, and is located farther out to see than any other wind farm. It consists of 174 seven-megawatt wind turbines that are each 100 meters tall. The blades have a circumference of 75 meters, and cover an area bigger than the London Eye observation wheel as they turn. Just a single rotation of one of the turbines can power the average home for an entire day, according to Stefan Hoonings, senior project manager at Orsted (DOGEF), the Danish energy company that built the farm.

The project will take the United Kingdom closer to hitting its target of deriving a third of the country's electricity from offshore wind by 2030. It's the kind of project that can help governments achieve environmental targets set out at this week's United Nations Climate Action Summit in New York. Some 77 countries committed at the summit to cut greenhouse gas emissions to net zero by 2050, but climate activists including Greta Thunberg say that major emitters must do more to mitigate rising temperatures.

    "but climate activists including Greta Thunberg say that" Seriously. Ignoring whether you are left, right, center, eco loving or eco hating. Why the f#ck does anyone give a crap about the opinion of a 16 year old kid? She has nothing to add to the conversation that wasn't spoon fed to her so that she can regurgitate it in from of a camera. By using her as some sort of validation for anything just makes the argument appear weaker.

        I remember not that long ago when professional, PhD scientists who disagreed with the "consensus" or the reasoning behind it were attacked because, even though they are outstanding scientists in their own field, they weren't CLIMATE scientists. They had no right to comment on the science involved in CLIMATE science because they were experts in some other kind of scientist. Did you point out that attacking the messenger showed that the climate alarmists had nothing to say?

        Greta isn't even a scientist, she's

      • Her position can't possibly be weakened because it's nonsense. She says clearly that cutting emissions by 50% in the next 10 years only has a 50% chance of saving us from catastrophic climate change. Bullshit. We can't cut emissions by 50% in 10 years, anyway. Not going to happen, but, then again, neither is the catastrophe that she's so worried about.

        I feel bad for her, because watching her it looks like she really believes that the earth is going basically die in her lifetime because we (older folks)

    • She can have an opinion just like anyone else. There are plenty of 16 year old kids with perfectly good , some even great, opinions.

      And she is correct. Greedy fucks are destroying the planet for short sighted profit motive.

  • UK's current electricity consumption is about 5 GW. That says this project, running at capacity, would be providing something in the ballpark of a fifth the country's power.

    Now imagine a few mines, planted on the underwater cabling by submarines, cutting the wires and suddenly dropping that feed.

    • Pull down a few high tension towers in the middle of nowhere. Chances are there aren't any redundant lines and it will take weeks if not months to restore. Don't even need explosives, submarines, just a tow truck.

      Saw that in 1998 with the Quebec ice storm.

      • I used to think that would work, but the utilities have helicopters that can fly in a new tower inside a few days. There are other parts that are much more vulnerable for a long term impact.

    This delivers about 1GW, presumably when wind conditions are optimal.
    When the air is still, it has no output. At those times we have to burn gas for power.
    That means that we have to keep 1GW of gas fired power stations available, even though we are not using them all the time.
    I am not trying to denigrate this project - it will reduce the amount of gas we burn for power - but what we really, really, really need is a method of storing lots of electricity.

    • What we really, really, really need is to manage demand for electricity to suit generation. Separate wiring into essential and non-essential and allow non-essential to be switched off as necessary. Maintain essential $/kWh at 10x non-essential, and include a max demand tariff so users playing clever games auto-switching from non-essential to essential when non-essential is blacked out, they get hit. If end user wants to store energy locally from non-essential, then they get the cost benefit from this.

      Fallback to solar also, or geothermal, or hydro, or ... Yes, we need energy storage. But even before such storage exists the wind power will still be highly valuable, especially as the wind is quite common out on the sea.

    Is this the kind of panic Greta is asking for?

    https://www.insidesources.com/... [insidesources.com]

    Throughout the Northeast, activists have held up natural gas pipeline construction projects, either by protesting or by persuading state or local government officials to deny permits or create other legal hurdles.

    âoeNew Hampshireâ(TM)s natural gas-fired generation has declined in the past three years and now is at its lowest level since 2002,â the EIA concluded. âoeThe decrease has been compensated for primarily by increases in coal-fired generation and hydroelectric power.â

    Merrimack Station could convert to cleaner-burning natural gas. But no pipeline runs to the plant.

    âoeThere is no plan to convert the plants to natural gas because there is no supply line nearby,â the New Hampshire Union Leader reported in January.

    Activists have been so successful in blocking new natural gas pipeline construction that theyâ(TM)ve guaranteed the continued operation of the very coal-fired power plant they now demand be shut down.

    I swear that if these panicked idiots don't stop this bullshit and actually think about what they are doing then they are going to get us all killed.

    Those windmill projects need backup power for when the wind doesn't blow. Right now this means natural gas. There are a lot of very nice developed sites to put these natural gas generators but they need pipelines to them so the generators have fuel. These sites exist where there are existing electrical transmission lines to get the electricity out, and train lines to get the equipment in. Sites that the utilities already own and have staff to run.

    I can hear it now, "But we'll use batteries!" Where are these batteries? Where can I buy them? How soon can I get them on site and operational? The answer is that nobody knows and so we need options. We can build new natural gas turbines to supply this power, or we can keep burning coal in boilers that are far beyond being in need of replacement.

    This is ignoring the problems of offshore wind being more expensive than nuclear power. But let's just assume it is cheaper than nuclear power. We still need natural gas until there are enough batteries to go around. Natural gas can't be easily transported in any way other than a pipe. Without a pipe the utilities will have to bring in coal and/or fuel oil to keep the lights on this coming winter.

    Greta says we should panic. I say we should think. Think about how this expansion of wind and solar power is changing the electrical grid. You people think it was so smart to hold up the construction of oil and gas pipelines? I say these protesters are ignorant, foolish, unintelligent, and just godawful screaming banshees that should be leaving this to the experts. Not only are they ignorant, they are willfully ignorant. It's not that difficult to look up how this works. We need reliable power or people will be freezing to death.

    All you children need to stop panicking, let the adults do their job, go back to school, and when you are old enough then you can help us keep fixing this problem.
