Wo don’t need nuclear in Germany, dear lobbyists. We need the opposite and are on our way to it. Decentralised grid. Local buffering, down to each house and EV (Vehicle to Grid IS a thing). Nuclear is done here. Deal with it.

What nuclear implies is centralised energy production, centrally owned grids. More control to less deciders. We need the opposite. Not only in Germany.

I shouldn’t have to explain the advantages of a decentralised power grid here on Mastodon ;)

Won’t happen over night, of course. But we are moving in that direction. 41% of electricity in Germany now is renewables [1]. Around 20% of the new buildings in my part of Munich now use geothermal solutions for heating (and cooling in the summer).

For European countries, we can have effectively free energy on the household level in the next 20 years. That is NOT a pipe dream. Note: household level. Not industry.

Work is being done as we speak on open standards for (hyper)local grid balancing. This could and should become an European project, backed by @EU_Commission This should be part of the ongoing Smart Villages project. Big cities next. Start small. Grow. Take over.

State sponsored programs for per building buffer batteries, geothermal and solar. EU wide bottom-up programs based on pilot small villages (NOT cities) on grid balancing based on open source/standards. Replace the oil tanks with batteries for starters. Germans my age will know ;) let’s bring 2 hours of buffer everywhere on the household level. Again. Household. Not industry.

@EU_Commission

@jwildeboer If this means I won’t have to constantly have my power flicker or go off on a clear calm day, without ever getting fixed because my hydro company apparently doesn’t care to fix it, sign me up.

@pete Something like a Tesla powerwall would already solve that right now. Tho know it as a USV for your house that smoothens out the grid shenanigans AND offers a few hours of resiliency. It’s a no-brainier.

@pete Sorry. German. I meant UPS. Uninterruptible Power Source.

@jwildeboer No idea a UPS was available for a whole house, though I imagine it’s quite expensive? I also live in a condo so I’m not even sure they’d let that be installed.

@jwildeboer Today's MaiLab episode opines that any new nuclear power plants would become operational too late anyway, and we've shut down the old ones.

@jwildeboer @EU_Commission

We need to reduce emissions and shutting down nuclear does the opposite.

@LeoSammallahti It doesn’t. We need to reduce emissions. So. Reduce energy use and use more renewables in smarter ways. That’s the better way. @EU_Commission

@jwildeboer @EU_Commission

Shutting down nuclear increases emissions just like shutting down renewables does. Doing other good things is not mutually exclusive.

The priority should be to get rid off fossil fuels. Once we have got rid of them, we can start shutting down nuclear. Doing the opposite implies that nuclear is worse than fossil fuels.

@LeoSammallahti Yep. That is my opinion. Nuclear has consequences we cannot contain. Nuclear is worse than fossile fuels in that regard. @EU_Commission

@LeoSammallahti Germanys decision to shut down nuclear cannot be reverted. Even the operators of the last 3 remaining nuclear plants agree. Nuclear is done in Germany. No way back. Now it’s about what next. On which I focus. That means replacing fossil fuels in new ways. Decentralised.

@jwildeboer @EU_Commission distributed electricity buffers that can serve as a virtual power station. Worked in Australia, can work here as well.

@jwildeboer You’re seriously making me want to move to Europe. You folks are so far ahead progressively, and in many cases technologically, that it makes my head spin.

@pete @jwildeboer sorry for the off-topic but I love seeing you converse in my Mastodon timeline and couldn't help but noticing your similar avatars. In fact, when I started following both of you I ended up confusing which was which for a few days.

@jwildeboer def shift zu erneuerbaren Energien stimmt aber es wird nicht ohne verzicht gehen. Weniger flüge, rindfleisch, fahrzeuge, exporte, bitcoin.

@jwildeboer those power plants also present themselves as some juicy strategic targets when it comes to attacks on infrastructure which apparently is a point that needs to be considered again. Much harder to take down a bunch of small energy production cells (unless, of course, you let them be produced by a small handful of providers and hook them up to the internet for easier management, then good luck to us)

@FlorianSchwalm The current work I’m observing handles that. Open standards for “to grid” solutions, defined fallback to local/neighbourhood management by the consumer, not the grid operator.

@jwildeboer that would be good. And also open source that firmware and let some smart researchers poke it until we are sure we want that controlling our net.
Is turning off electricity remotely with smart meters still on the table?

@FlorianSchwalm I would actually see that as part of the solution. When needed, for example in cases of catastrophic situations, where power gets redirected to where it’s needed, you should get a signal to switch to your local battery/backup until the grid can deliver again.

@FlorianSchwalm you could even take it to the next level. I will give you my stored electricity if you have problems paying the bill. That’s the power of (hyper)local grid balancing.

@jwildeboer that will be fine as long as those signals are implemented in a safe way and can not be abused to purposely destabilize the grid by taking off and taking on households en masse. And I don't want to have this rely solely on trusting the big energy companies. Because then we'll get "military grade encryption with added Blockchain security" and alike
But hoping for the best :)

@FlorianSchwalm Absolutely. Which is why I am promoting open standards and open implementations, starting from the village/street level.

@FlorianSchwalm The social implications of „helping your neighbour“ on that level create awareness for the concept when it grows from local tonregional to national to EU wide. That is also why it should be focused on the household level.

@FlorianSchwalm I’d prefer to give my excess electricity to my neighbours fridge instead of the anonymous grid :)

@jwildeboer a mix of the two is probably a good thing. Centralization brings the benefits of the economies of scale. Decentralization brings resiliency and agility. The sum of the two should be big enough that no single component can cause a catastrophic failure….

@ayourtch Sure. Which is what we are doing here. Without nuclear. We already see more and more net positive houses and buildings. That in sum produce more energy than they consume.

@jwildeboer I was going to ask about the impact of EV on that. Now, I need to research EV to grid. Honestly, I'm skeptical about EV due to conflict minerals and impact of production and disposal vs biodiesel, etc. Was hoping we'd have a hydrogen powered vehicle solution by now.

@vwbusguy Hydrogen just doesn’t work for cars. There is a lot of research on that. Toyota and VW stepped out of it for good reasons.
