<p>Lack of sun/wind in Denmark correlates strongly with lack of sun/wind in Germany and surrounding countries. The importing of electricity works precisely because the surrounding countries still have the "baseline" power plants the article dismisses so boldly.<p>Transmitting electricity over larger distances remains very expensive, which is why the idea of using the African sun for Europe (e.g. Desertec[1]) has stalled [2].<p>[1] <a href="https://de.wikipedia.org/wiki/Desertec" rel="nofollow">https://de.wikipedia.org/wiki/Desertec</a><p>[2] <a href="https://www.youtube.com/watch?v=Jmcgdh_0gyo">https://www.youtube.com/watch?v=Jmcgdh_0gyo</a></p>

<p>The article succumbs to wishful thinking in critical areas:<p>"So yes, Germany has a lot of gas-fired plants, and a lot of coal-fired plants, but they are actually used very little - only when demand (including from France) is very high and renewables supply is very low - which does happen, but not that often anymore."<p>This will continue to happen for the foreseeable future during the winter months. Solar is almost neglible, and wind obviously has slumps.<p>To fix this problem, the article brings up the recurring theme of saviour technologies that simply are not there yet:
"flexible generation, whether hydro, new forms of storage"<p>Total consumption for 2021 in Germany: ~500TWhs [1]. That means ~10TWhs per week.
At the moment our storage capacity is in the small GWhs ballpark [2]. We would have to increase this thousandfold. I haven't seen this gap adressed with actual projects yet.<p>[1] <a href="https://de.statista.com/statistik/daten/studie/164149/umfrage/netto-stromverbrauch-in-deutschland-seit-1999/" rel="nofollow">https://de.statista.com/statistik/daten/studie/164149/umfrag...</a><p>[2] <a href="https://www.erneuerbareenergien.de/transformation/speicher/wachsender-markt-deutschland-mehr-als-sieben-gigawatt-speicherleistung-installiert" rel="nofollow">https://www.erneuerbareenergien.de/transformation/speicher/w...</a></p>

<p>Please respond to my argument instead of implying bad faith.<p>I can sharpen my argument even further:<p>Existing nuclear reactors - keep them going. They are <i>here today</i>.<p>Solar - leverage its decentralized, bottom up expansion by the people that can use their own roofs, reduce beaurocratic hurdles. Its expansion does not have to wait 8 years. The products are <i>here today</i>.<p>Power 2 Gas - celebrate existing products on the market. They are <i>here today</i>.<p>All these things <i>are here today</i> and part of a solution which contains many parts. I welcome each and every betterment, because we will need it.<p>You on the other hand are dismissing key tools and instead focus on <i>one</i> thing that <i>is not here today</i> and will <i>maybe</i> be ready in 8+ years.</p>

<p>Its definitely worth it to use all available space.<p>Still, it definitely cannot generate enough to bring you through the german winter. 
Some example numbers I have read: A 10kWp solar system that generates up to 1,400 kWh in a summer month will only provide about 200 kWh in December.</p>

<p>New nuclear reactors are also not here yet. They might become ready in 8+ years if started now.<p>So the solution is simple. Nuclear has its place. Power2Gas too. Build and invest in both. And in the meantime, use what we have without ideolgical eye patches.</p>

<p>Yes, I was not proposing such system as a large scale solution for the coming winter. It would be prudent to keep our nuclear reactors running for now.<p>As always, There is No Silver Bullet™.<p>Nuclear is not the perfect solution. It cannot be powered on and off on short notice, which would be useful for complementation of solar and wind that have high power output, but also sudden slumps. Ironically, the ideal companion for renewables would be gas...<p>Lithium batteries could compensate short outages, but don't have enough (feasable) capacity for long seasonal shortages.<p>Enter Power to Gas. Hydrogen can be a good tool in that area.<p>A commerically available hydrogen storage system (that is in high demand even despite its price point) will definitely accelerate innovation very effectively.  I think this tool will be available quite soon for mere mortals.</p>

<p>You could have made the same argument against solar panels 15 years ago.<p>This is a pioneering product for early adopters - expect prices to go down significantly with economics of scale. And further research in this area is far from exausted.</p>

<p>There is a working system commercially available in Germany, but it is pretty expensive [1]:<p>Long-term energy storage with hydrogen, with 1-5x 300 kWh. Which allows for full electric independence (not including heating though).
Price: 85,000-125,000 €, minus government subsidies.<p>[1] <a href="https://www.homepowersolutions.de/en/product/" rel="nofollow">https://www.homepowersolutions.de/en/product/</a></p>

<p>I agree that it can depend on social circles.<p>Still, I would argue this:<p>Lets say your 19 year old daughter wants to introduce her boyfriend of same age into your family.<p>How would you rate her (and his!) seriousness if<p>a) they lived in his apartment or<p>b) they are organizing their wedding.<p>I would wager b) would be "well-established" much quicker, especially in the wider circles, and thus have more "social resources" sooner, thus giving their potential offspring better chances. Of course, with kids out of the picture, it wouldn't make much difference. But that is exactly my point: Marriage serves having children.</p>

<p>It is <i>quite</i> debatable if children actually stabilize marriages (I know a lot of counterexamples).<p>I would argue exactly the other way around:
A lasting marriage is not itself the goal (though certainly nice to grow old together), but serves the purpose of raising offspring - that's what counts for every species that has survived.</p>

<p>That doesn't fit my experience at all (I'm from Germany).<p>As soon as couples start to have concrete plans for children (or children are already on their way), marriage suddenly becomes very relevant for many relationships, and is often demanded by at least one side of the partnership.<p>This puts aside the romanticised view of marriage (which might be perceived equivalent to living together) and points to a more fundamental reason for marriage: Securing resources for your offspring. And offspring needs <i>a lot</i> of resources for a <i>long</i> time.<p>In the end, its commitment that counts. And marriage was <i>built</i> for ensuring commitment as much as humanly possible, with a high barrier for abandoning.</p>

<p>For a big portion of the app, I would agree (arguments about native feel aside).<p>But well, there is the virtual planner feature that makes heavy use of carefully tuned iOS gesture recognizers for zooming, panning, dragging, tapping and holding, all in combination for a smooth and useable editor on a small screen.<p>Not that I have actually tried, but I suspect I would have to lay more groundwork to implement the same experience with the browser DOM.
This could of course just be a lack of knowledge on my part, but my time is finite :)</p>
