This is my 3MT, such a long time ago now. It was my first go at engineering communication, and it led to so much more for me! I highly recommend participation for every PhD candidate, its usefulness for networking and job searching has been so valuable, much more so than any of my academic papers!

So, how do we maintain sufficient power to the grid when there are days of "NO" wind? Please do not say "Solar", they don't work at night. I have an electrical trade background and worked in electrical power generation science physics.

Whether is a weapon and the effort to develop more tools to control it is costing billions of dollars. My dear Rosie can you tell us to relax...coz its not the fault of you burning Petrol in your car ..it is the gigawatts going into heating layers of atmosphere in jeo engineering harp experiments

And your still not even close to the solution. Don't kid yourself that this is an easy solution. It is going to take a few more decades to get the technology to go green. Do not kill traditional sources of energy before you get there, otherwise we will see poverty and destruction on a grand scale. All good things take time and patience.

And a couple years later, gas is the hands down cheapest way to rapidly reduce emissions globally without having to put up with the fact that wind is so infeasible that it probably shouldn't ever be used anyway (even if the turbines were free)

What do you even mean by the last statement? How are they infeasible?

Ok, first off they feed you nonsense like "capacity factor" to pretend it will average out...but in reality across whole nations the wind will drop to near zero, sometimes for days. And the wind's wild fluctuations require wild throttling (minute by minute) of the existing power sources...which makes them far less efficient, essentially nullifying the majority of the supposed "benefits". Of course, green groups then feed you these figures, distorted by their own worthless form of power...chalking up wind's negatives to fossil fuels and claiming wind lowers power costs...when what REALLY happens is that when wind finally produces, the value of that energy is near zero (and sometimes literally below zero), so the turbines can never actually pay for themselves without subsidies. On the other hand if we switched to nuclear with fracked gas for load following/peaking, emissions would drop rapidly. And because even the most materials intensive version of nuclear plants still use 1/10 the materials, labor, and maintenance of wind...it's something that could actually be done and frequent blackouts.

That intermittent sources of energy can overproduce and cause prices to crash is an issue, I'll grant you that. But there are other solutions to this problem, such as more load flexibility. In my view it's almost ridiculous that in the electricity marke the supply curve is price sensitive but demand curve is almost a vertical line. Negative prices are s result of renewables plus inflexible demand. In some places renewables are the cheapest marginal source of energy, and if demand can be made price sensitive, then the intermittency becomes less of an iissue, an users can take advantage of the low prices. Finally, the cost of renewables is going down fast, and even in places where they are not yet competitive, eventually they will be, and it makes sense to try and take advantage of them. If you can use gas for peaking in a nuclear dominated grid, you can do the same in a renewable dominated grid. If you're worried about the rare occasion when there is almost no renewable output, and thus the gas capacity would have to be large, electric vehicles including hybrids would be perfectly suited to act as the final high cost generators. I don't hate nuclear, but I don't think we'll redo to or tga it will be the cheapest option. As wind and solar matures labour will go down. Perhaps we'll move to deep water offshore wind, where the turbine can be towed out horizontal, rotated 90 degree and connectedness of existing anchor points. Solar PV may well shift to flexible panels which can be rolled out and glued to roof surfaces. Many ways to reduce labour exist.

Ben Wilkinson Load flexibility is just another moronic term that's been dressed up to sound nice. Here's what I propose...YOU FIRST. Let's see if you understand why there's no load flexibility after you're sent home from your job for lack of electricity or your business is shut down...to meet the demands of an inadequate energy source. Let your electric car's batteries be sucked dry to meet a shortfall you demanded we create. Let your heat be shut down in winter, your AC be shut down in summer. The reason you repeat these bullet points is because you've never thought about them or researched them. It would be easier to fit nuclear to our needs than to try to shoehorn our lives into the whims of the wind. And for what? The delusional idea of "sustainability" when there's enough ore for nuclear material to power our civilization for 10000 years (8 billion people at US per capita energy consumption..including industry/transportation) before we have to switch to taking it from the oceans...which won't stop being a source until plate tectonics stop. It's 100% pure delusion brought about by trying to solve the imagined problems from 100 years in the future, with the crappy technology we have today...that doesn't even work today.

+poitsplace you make load flexibility sound terrible when intrinsically it isn't, but previous applications may not have been ideal. done at the device level it could be almost unnoticeable. Eg a well insulated fridge with some PCM as thermal storage. The fridge would ensure its always sufficiently cold, but it would have some choice about when during the day it consumes power. If your power was 50c at night and 10c during the day, you would have to seriously consider the investment.

I'm going to give you a little lesson on climate change, we have been coming out of an ice age for the last ten thousand years what does it do when you come out of an Ice Age it warms up and it hasn't stopped in the last ten thousand years so how are you going to stop that you're not, Mother Nature will stop it, and then we'll go into another Ice Age that's how simple it is. Don't get me wrong I want clean water I want clean air I want clean Farmland because I'm a farmer + a dot Connector

You can just tell by your grammar, atrocious punctuation, and poorly formulated ideas that you don't have a clue what you are talking about. Here's a little idea for you. Instead of spouting some rubbish you picked up off another ill-informed dolt on YT, do a little research for yourself into the science of climate change. That way you'll learn how we can easily tell the difference between "coming out of an ice age" and a situation being created by human activity. How about that? Otherwise, you know, you can just STFU! That would be fine too.
