yeah the new it only have like a billion other stocks for these scumbags to get rich off of and short into the ground
Nonsense. Just build a Dyson sphere around it and be the sole owner of the entire star’s energy.
This is idiotic. The fact is your electricity transmission system operator has to pay a lot of money to keep the grid stable at 50 or 60Hz or your electronics would fry. With wind and especially with solar power, the variable output is always pushing the frequency one way or the other, and that creates a great need for costly balancing services. Negative pricing is an example of such a balancing service. Sounds good, but for how long do you think your electricity company can keep on paying you to consume power?
People also don’t realize that too much power is just as bad as too little, worse in fact. There’s always useful power sinks: pumped hydro, batteries, thermal storage, but these are not infinite.
Stupid question but can we not like, make toggleable solar panels? Like if I Just pull the plug extracting power from a solar panel does it explode or break or something?
Not really. You can discharge into the ground, but for large installations even the ground has a limited (local) capacity.
Edit: explain yourselves, downvoting cowards
Why isn’t this as easy as storing some of that excess energy in a home battery and letting the rest down in a wire into the ground? Then if it’s smart enough it could only give back energy when needed.
The easiest solution is to send the power somewhere else where it can offset the use of fossil fuels. This solution is fraught with political hurdles, subject to market forces (due to privatization) and often grid compatability issues(looking at you Texas). It is, however, a time tested and common method for mitigating excess production.
While water in pipes is often a metaphor for electricity, it’s not particularly useful here. You can’t ground out part of a charge. Energy storage is the solution though. Batteries are good, pumping water up back up into dams to be regained from a hydro plant when needed is ideal, as I understand it.
Well, that’s what they’re doing some places. The batteries assets are not in private homes usually though, they’re by themself or run by power-consuming industries. Batteries are expensive though, and they degrade quickly if you use them wrong. In the EU, ENTSO-E defines the market rules, trade systems and messaging systems that energy companies and asset owners play by. Sometimes the revenue-generating asset is a battery, sometimes it’s a hot water boiler, wind park, factory, hydro plant etc.
With wind and especially with solar power, the variable output is always pushing the frequency one way or the other, and that creates a great need for costly balancing services.
Speaking as a flashlight enthusiast…there’s many different ways to get a constant and consistent current. Sure we’d need to scale it up from a pocket-sized device to a whole fucking power grid, but with a big enough driver with the right arrangement of capacitors and all that, you’d easily be able to get a totally consistent current out of wind or solar
Having knowledge in power electronics i can confidently say the DC output of solar is easily and regularly inverted in phase with grid. In fact, DC is often used for undersea cables switching AC to dc then back to AC, All at extremely high voltage and varying demand(up yo 600kV/600MW but varying by installation).
Wind turbines go online after the blades start spinning and connect to the grid in the same way as any other generator, controlled by internal electronics. Power is regulated through blade feathering and can be turned off as supply exceeds demand. This, other than for maintenance reasons, is why you might see one turbine spinning while the next is standing still. This capability actually means the grid is MORE stable with wind power.
Any further fluctuation is managed in the same way as conventional power generation.
To start the frequency of the electricity isn’t the issue. Second all modern electronics use switching power supplies which don’t care about frequency. That’s two incorrect things just in the second sentence that they literally said was fact.
The “problem” of negative energy costs is easy to solve, but quite costly.
Build water desalination/carbon capture and storage/hydrogen generation plants that only run when the price goes below 0; even though these are very energy intensive, they would help stabilize the grid.
Then build more solar; you want to try to have the daytime price stay in the negative as often as possible.
The solution we’re using instead of course, instead of all that environment crap you suggested, is running huge crypto farms only during the hours when the energy is in surplus.
To be fair; this is a valid use case.
If you are a solar power producer; rather than offering your energy at -ve rates; run a crypto farm when the output is too high. This is far better than running the same farm on coal.
But it would be better going into something useful.
I want to pre-empt the argument from the Bitcoin people that while this is a logically sound argument for how Bitcoin mining could potentially help the environment by making renewables more economically feasible, using this argument to describe Bitcoin mining electricity usage is completely invalid—Bitcoin mining as it exists today does not merely use excess renewable energy; it consumes energy even in times of demand when it could be given to residential, commercial, or industrial customers. Without the excess demand from today’s Bitcoin mines, the capacity that is freed up can be used to close fossil fuel power plants.
you want to try to have the daytime price stay in the negative as often as possible.
That’s not exactly conducive towards people building more solar.
The solar isn’t the goal; the energy is enabling the value in other parts of the economy.
In fact; energy supply is so important to the reasonable functioning of the economy. It should be taken out of the profit driven cycle of business.
Look at what happened with WPI in Ohakune and PanPack when energy prices sky rocketed a few months back.
Literal free goddamn energy from the sky and these greedy fucks are going to burn the world down because they can’t flip it for a buck
It sounds dumb, but because you can’t turn off solar power, if it produces more then you need, you have to use it somehow or it can damage equipment. Hence the driving prices into negative territory. It’s a technical problem more than it is a financial one.
It is a financial problem. Technically you can just cover the solar panels. But that’s not good financially.
Your “technically you can” is actually a huge logistical nightmare to implement.
Having electricity rates go really low is intended to incentivize people or companies to sink the excess energy to wherever they can. And also to discourage producers to produce more at that hour, if they are able to.
“Damaging equipment” is just nonsense. I’ve got an off-grid solar system. When the battery is fully charged the solar panels simply stops producing. It has potential (voltage) but no current until you draw power. Just like a battery is full of energy but it just sits there until you draw power from it.
All solar systems could have smart switches to intelligently disconnect from the grid as needed, some inverter already do this automatically. So it’s not a technical problem. It’s a political problem.
This can cause degradation of the PN junction on the panel shortening life. The plans I’ve seen all have a resistive heater some place to dump the excess when full. Smart equipment does help mitigate most issues like moving the resistance point on the panel for lower efficiency when signaled to do so but less is not the same as none.
It is a technical problem of how can you convince electrical companies to overcome a problem they have no financial incentive to solve.
that’s not a technical problem. that’s a weakness of the people’s resolve problem. we can, at any time, force them to do the right thing.
Sounds like energy companies or independent entities should invest in energy storage so they can get paid to draw from the grid.
But then you’ve got cities like Morro Bay, CA that are trying to stop a plan to replace a coal plant with a battery storage facility because batteries are supposedly dangerous.
No, unfortunately, you can’t.
Ground doesn’t typically dissipate power, rather, power is dissipated in the circuit/load — so if you just hook a wire to ground, you’re dumping gobs of power into the wire. If you do this in your home (DON’T), best case it will trip the breaker, worst case it will melt and catch something on fire.
It’s easy enough to burn a kilowatt — just boil some water. But it’s entirely something else to burn megawatt, or yikes, gigawatt scale power.
Didnt Nikola Tesla try to sell Westinghouse on providing free unmetered electricity to everyone on earth and got laughed out of the room?
