  You’re right in that I used yearly numbers and wrongly used them as daily numbers. The stats are from the central statistics bureau, and unfortunately it auto translates poorly www.cbs.nl/nl-nl/cijfers/detail/83989NED

  The numbers include use of gas and coal for heating and industry, which often get ignored by people (mostly because it makes us look fucking terrible in renewable power stats).

  3. The assumption that you must store an entire day’s worth of energy demand is ludicrous.

  It is, in fact extremely generous, if you’re using the solar+storage method. But let’s go with this and I’ll demonstrate what it means in practice.

  Let’s assume that we need to cover all of the electricity that is currently produced using coal, oil and natural gas. All other sources already have infrastructure supporting them, including the pre-existing solar. This amount comes to about 48% [1], so let’s assume 50%.

  You just made the switch from “energy used” to “electricity generated”. For a country that still does most of its heating with imported gas, that’s a big difference. The real amount of non-fossil energy is about 18%, call it 80% fossil.

  5. Now, we need to cover 50% of 50% of 1.9 petajoules at any one time, or 475 gigajoules, at any one time.

  So it’s 50% of 80% of 2600/365, or 2.8 petajoules. So that’s only 10 of those facilities. Not great, not terrible. But that’s not the point. Nor is it important that their demo facility has a height difference twice that of the whole country.

  ---

  Let’s stick with the “one night of power store is plenty”.

  That’s true, but only if you can use solar to power your whole day. In other words, to make do with only 1 night of storage, you need to generate all your power for 24 hours in December during December daylight hours. Assuming it doesn’t snow, one solar panel produces about .15kwh on a december day (working off of 2% of yearly production happening in december, and 300Wattpeak panels), or 540kj.

  So you’re right, we only need to build 10 facilities twice the height difference of the entire country, to save one average night of power. Unfortunately in order for that to be true, we would also need to cover about 960.000 hectares in solar panels, which is roughly twice the total built up area in the country, including roads.

  And that’s assuming you keep a perfectly level energy use throughout the year, and a perfectly level production during December. Neither of which is true, and generally the worst days for solar production are the worst ones for use as well.

  On the bright side, if we can put down two extra cities worth of solar panels for every city, we’ll probably have no issues building 600m tall hills by hand as well.

  There is simply no excuse other than corruption for the fact that we don’t just run a couple trains up a hill when we need to store massive amounts of solar energy.

  Well, I don’t know about you, but the nearest hill to me is 200km away, and a whopping 300 meters above me.

  Also, scale is a huge fucking issue. The little country of the Netherlands, where I ha etl

  So let’s store 1 day of power, at 100% efficiency, using the tallest Alp (the Mont Blanc).

  Let’s round up to 5000 meters of elevation. We need to store 2.6e18 joules, and 1 joule is 100 grams going up 1 meter. So to power a tiny little country, we need to lift roughly 5e13 kilos up the Mont Blanc. To visualize, that’s 1.7 billion 40ft shipping containers, or roughly 100 per inhabitants.

  Capturing all the extra carbon from the atmosphere is not as expensive as it sounds like. It can easily be done by a few rich countries in very few decades once we stop adding more there every day.

  What?

  For starters, carbon capture takes an insane amount of power. And to follow up: we couldn’t even build the facilities is “a few decades” even if we free power and infinite money.

  Do you know WHY they went over budget?

• ⁨Comment⁩ on ⁨Anon questions our energy sector⁩ ⁨⁨12⁩ ⁨hours⁩ ago⁩:

  Most of those didn’t involve the magic rocks, and most didn’t hurt anyone.

  More people die creating the building materials for a powerplant (or a windmills, or a solar panel) than ever during operation. The numbers really don’t matter.

  I honestly don’t care what we do, as long as we stop burning coal, oil and gas. The way I see it, every nuclear plant and windmill means we all die a little later.

  It’s an immersion heater. Basically a heating coil in a metal tube that you plug into the wall to heat whatever you dunk it into.

  Don’t skip the betavoltaic battery, (or the brand-name: Betacel), which turns beta-radiation directly into electricity. They used them in the 70s to power pacemakers, since batteries were kinda shit back then, and implanting Prometium into people is just too epic not to do.

  Nowadays we have tritium-decay betavoltaic batteries, on satellites, buried or underwater sensors and probably some too secret military stuff.

  In the Netherlands, yes. Ibuprofen is considered “stronger” or at least more serious. Most of that is because the general consensus seems to be to take 2 paracetamol (1000mg) and if it doesn’t help, add 400mg of ibuprofen on top.

  Yes, a potential future application, in a system where we basically always have more renewable electricity than we can use could see some great hydrogen-based storage in hydrogen.

• ⁨Comment⁩ on ⁨Know thy enemy⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  Hydrogen is just worse natural gas. They crack natural gas to produce hydrogen, and its fucking terrible. Hydrogen creates about 4 times more CO2 than diesel, simply by how the vast majority of it is manufactured
