Hi! Thank you so much for commenting. Heat pumps move heat from on place to another rather than only transforming it from another form of energy. What are your thoughts on practical and engineering challenges?
@@NetZeroTech Hi, Any 'heat pump' is only possibly functional inside another, bigger and older running parent heat-pump. Let the operators of a power station run out of gasoline, food, medicine or shoes - unable to arrive at work - and the station stops sooner or later. This is despite there is no shortage in fuels to keep the station running for longer. Ignore changing the engine oil of your car, and the car degrades and becomes obsolete in a hurry. The total energy put into a fresh batch of engine oil until applied into your car is unfathomably greater than all the useful energy your car has delivered since last oil-change. Engineering and technology come secondary. Thermodynamically, there is no such thing called Capitalism. This is owing to the fact that fossil fuels have been traded under the doctrine of what's called 'supply and demand', not on the basis the stuff is finite.

Hi Hassan, I‘ll take a look at it. I’ll try, no promises. A lot of thought goes into picking a subject. Thank you so much for the suggestion! 🙏 Katha 😀
This renewable energy conept doesn't work as good as people may think. We import 10% of our electrical energy from france (nuclear) and poland (coal). With the GEG (building energy law) and the electrification of the traffic, the import volume will increase. This is statistical average. There are in fact days (especially during the cold months) when there is almost zero generation from renewables (no sun, no wind) and there are days when we have to export our energy almost for free because renewables generate over the nation's demand. There is still missing the large energy storage technology to make this concept work. Germany is still and will always be dependant of nuclear and fossile energy, but it has given up to produce it on its own. This is basically "greenwashing".
@@lorenckotini Absolutely. There is a payback time though. It depends on the project how long it takes to have it pay itself off and after that period to save money compared to the alternative.
Seems like most people don't know what to expect from this winter's energy prices and availability in Germany. What are your thoughts on how the winter will go. I think the phase-out date of 2 nuclear reactors has been extended and there is a plan to replace their load with renewables.
I think they will just end up inporting loads of nuclear generated power from france and hydro from norway. Maybe with some wind and gas generated power fron the uk, in the long term. .
Thanks for sharing your thoughts. Wholesale electricity trading with its political and infrastructural landscape is complex. I'd have to dig deep to give you a good response. The video should provide some insight. There have been geopolitical developments. Have a great week! Katha
I light of the events of the past few days what will happen when all of the nuclear power plants are taken off line (12.5% of current power) and the amount of gas coming from Russia is reduced due to possible sanctions and or disruption of supply. What is the backup plan for Germany?
You can ramp up other sources. Prices have been volatile. Geopolitical stability is certainly important to avoid resource conflict escalations. Backup plans to different scenarios are an interesting subject to look into, e.g. another video. Thank you for sharing your thoughts!
renewables including hydropower and biomass. The percentage of solar and wind is pathetic. Offshore wind has cost of 2 to 4 cents per kwh in operation and maintenance cost. wind also decreases by 4 percent of nameplate capacity every year. how in the world is that supposed to come close to working, the resistence the german people have is the 3.5 percent per year slide into poverty that this mess is responsible for.
Hi Marc, Nuclear fission can be a polarizing subject due to the waste. The new reactor generations produce less and short-lived radioactive waste. Thank you for leaving a comment and sharing your thoughts. Germany phases out all nuclear fission this year. Thanks, Katha
If you give me 50 million euros, I can give you a drawing of a new electricity invention, how much electricity you want, where there will be no cost, no pollution, and the air will be clean.
I don't know much about grids (I guess I know a little more after your video), but renewables like wind-farms are, in my opinion, horrible. I've encountered them in a few places up-north (Michigan). They are disruptive, kill a lot of birds, and ruin the scenery. Hopefully, the fusion experiments like ITER, Wendelstein 7-X, NIF, etc. will eventually pan out.
Hi William, Thank you for sharing your thoughts! 🙏 You have some really good points. I just wonder how we are going to get to net-zero carbon without wind. Fusion would be great. I'd be surprised if we see economically viable fusion in our lifetimes, though. PS - Unregulated electricity is a commodity, thus, it comes down to the lowest cost, which can regionally vary. Wind is already economically more viable in many places. I am expecting carbon eventually to be priced in, removing direct and indirect subsidies for fossil fuels that future societies have to pay for. This can take several more massive natural disasters for humankind to finally take action. I wish we where able to much more flatten the curve to reduce natural disasters and increase geopolitical stability.
@@NetZeroTech Yes, you are probably correct about fusion, but hopefully you will be surprised. The Chinese just made a 17 minute run at 70 million C (granted it is nowhere near the 150-200 million C required). Maybe ITER has some surprises, or one of the other dozen and a half (or so) fusion experiments around the globe. The environment/climate is definitely an issue, and it seems prudent to find solutions. If wind and solar will work, then I’m all for it. But would renewables work for whole economies? It would be nice to know more. Hence, I will continue watching your videos.
I saw the record at the Chinese nuclear fusion test facility and mention it in a comment below my last fusion video. This is exciting to me. 😃 Steady-state conditions for magnetic confinement are very challenging. Hydro power is a great renewable power source. It also has a critical systemic function, since you can start it without electricity in the case of a blackout. I think you can run whole economies off of renewables including green hydrogen power plants. Since electricity is a commodity, It all comes down to costs. And humankind is only slowly pricing in the cost of fossil fuels for the current and future system as a whole. Thank you for watching my videos. 🙏
@@NetZeroTech I saw your first video on fusion again (this is what brought me to your site). Then I saw your other video on fusion (missed it the first time around, sorry about that). Yes, turbulence is a “tough nut to crack.” Fusion, climate, and so on are exciting to me as well. My perspective is from mathematical modeling and simulation (although my project is on modeling/simulating friction - the models in general are interesting). I would agree that oil and coal need to be cut back (and price in the cost), but I have concerns about renewables. I worry about the landscape being cluttered with solar panels and wind-mills and the rivers damned up. This stuff impacts the environment as well. I would almost rather see updated fission plants. Now that I’m aware of Germany’s renewable plan-of-action (from your video) I’ll try to look into it some more. I don’t see how this could work everywhere with geographical locations and politics. Hopefully, you’ll continue making more videos.
@@williamschacht Thank you for following up on this. Your friction modeling/simulation sounds interesting. Perhaps you wanna share more at some point. As an engineer, I applied fine-element, thermodynamic, and ab initio modelling using different programs and in some cases writing new code. But at the end of the day, it still seemed come down to trial and error. Industrial/commercial materials and their applications are usually iterations of their previous versions, plus they get tested a bunch before they're thrown at the market. 😀 Thanks, Katha
Hi Gabriel, I try to make my videos fact-based. There is always a choice to which facts to present and how to present them. Do you have data to back your hypothesis? Thanks1
Hydrogen power plants is a bad idea. You have to make the hydrogen and that is very energy intensive. Why not just use that renewable energy directly instead. If you overbuild wind turbines, you can idle them when you don't need as much power. They can be brought online when needed quickly.
Thank you very much for watching and taking the time to comment! I like the idea of overbuilding wind turbines. Comparing one energy source with the other, wind turbines are indeed more efficient than hydrogen power plants. However, if you look at a portfolio as a whole, hydrogen can complement wind turbines in a way so that the overall portfolio efficiency is higher combining both vs using wind only. The excess wind energy can be stored using hydrogen and used when needed. Offshore wind is on the rise: www.statista.com/statistics/476327/global-capacity-of-offshore-wind-energy/
wind and solar never give you more energy than you put into them. it is like eating celery. the more and faster you eat. the quicker you starve to death
talking about hydrogen while they already have messed things up so bad the low output of crappy wind and solar has caused fertilizer plants in germany to shut down due to the high nat gas prices. this WILL cause millions to starve and very soon at that.
Hello EurobroWarriormonk. How are you? I am not sure how I can help you. With regards to your ideas: If you have a data-driven case on the effects of energy sources on food supply, I'd appreciate an opportunity to take a look. My understanding is that climate change already has massive negative effects on reliable food supply. Extreme weather, droughts and flooding will increase as a result of oil-based economic systems, causing additional pressure on the resilience of our agriculture systems.
