Mrdarknezz··on Geothermal may beat batteries for energy storage
So far there is no proven technology that scales to grid level? We are closer to achieving fusion than large scale energy storage.
Mrdarknezz··on Geothermal may beat batteries for energy storage
Well it doesn't really change the fact that batteries: 1. Doesn't scale to grid level 2. Isn't interchangeable with firm energy sources
Mrdarknezz··on Geothermal may beat batteries for energy storage
Battery costs are literally rising
Mrdarknezz··on Geothermal may beat batteries for energy storage
Batteries are not cheaper than nuclear.
Mrdarknezz··on Geothermal may beat batteries for energy storage
Batteries is not an alternative to firm energy, you still need firm energy to balance the grid wether it's from nuclear/hydro/geo or fossil.

That's why all decarbonized grids have hydro/nuclear as their main source of energy.

Mrdarknezz··on Geothermal may beat batteries for energy storage
Energy storage is the monorail of energy technology, expensive, unnecessary and conventional technologies like nuclear, hydro and geothermal is better in every regard.
Mrdarknezz··on BYU profs create new nuclear reactor to produce nuclear energy more safely
Well there won't be many towns left unless we start to build alot more nuclear thanks to climate change.
Mrdarknezz··on Europe's Newest Nuclear Reactor Eases Finland's Power Problems
Nope Nuclear is the cleanest form of energy production https://unece.org/sed/documents/2021/10/reports/life-cycle-a...

You can't replace Nuclear with intermittent energy, they serve different function. So far the cheapest and the largest deployment of green energy has come from Nuclear and Hydro.

Mrdarknezz··on Big money, nuclear subsidies, and systemic corruption (2021)
Yet so far it's the most effective system we have to transfer value
Mrdarknezz··on Big money, nuclear subsidies, and systemic corruption (2021)
No, intermittent energy can't load follow since it's intermittent. You can see this mostly in europe where those that keept nuclear online has cheaper grids that those that didn't. Especially true for this is in germany
Mrdarknezz··on Big money, nuclear subsidies, and systemic corruption (2021)
Yet this "myth" is what has lead to countries with heavy amounts of green baseloads being able to decarbonize and those without are still struggling.

The failure of the Germany energiewende is a great example, Californias struggle is another.

Mrdarknezz··on Big money, nuclear subsidies, and systemic corruption (2021)
Well I think comparing intermittent energy with baseload energy 1:1 is kind of unfair since they fill different functions in the grid. It's cheaper and less risky to produce a bike than a train. Both are a means of transportation but you can't replace trains with bikes or bikes with trains.
Mrdarknezz··on Big money, nuclear subsidies, and systemic corruption (2021)
So far there is no real life example of what you are suggesting. The only countries that has gone green include either nuclear or hydro in their mix. Storage + Intermittent is not enough to power a modern grid. Also yes you do need to always meet demand to ensure the frequency is stable, otherwise you'll have massive problems.
Mrdarknezz··on Big money, nuclear subsidies, and systemic corruption (2021)
... What?
Mrdarknezz··on Big money, nuclear subsidies, and systemic corruption (2021)
You still need some sort of baseload to support wind/solar. That can come in the form of Hydro/nuclear if you want to decarbonize or do like germany and build massive amounts of gas.
Mrdarknezz··on Big money, nuclear subsidies, and systemic corruption (2021)
"these renewables can generate electricity at much lower costs than fossil fuels and, especially, nuclear power. In the United States, unsubsidized wind power costs fell by 71 percent between 2009 and 2020, whereas unsubsidized utility scale solar energy costs declined by 90 percent during the same period."

This was a weird take from the author since NPP aren't interchangeable with Wind/solar-parks.

Seems more like a nuclear hit piece than an actual attack on lobbyism.

Mrdarknezz··on Do You Need Web3?
Yeah like every other technology it will either ultimately prove its worth or fade into obscurity like everything else. I just don't see the point with these extreme viewpoints.
Mrdarknezz··on Do You Need Web3?
Yeah there sure seems to be alot of scams. But the idea that it would dismiss everything related to the blockchain seems like taking it a step too far in the other direction? I'm no expert but I get extreme flashback of the era when PHP was considered radioactive garbage and any attempts of nuance was struck down
Mrdarknezz··on Do You Need Web3?
I'm not sure when it happened but all of suddenly the discussion on anything related to blockchain became very black and white. Anyone that tries to nuance the topic gets immediately called out as favouring this or that.
Mrdarknezz··on Energy Prices in Europe Hit Records After Wind Stops Blowing
It's time for a nuclear expansion so we can transition out of our fossil dependency.
Mrdarknezz··on Almost free serverless on-demand Minecraft server in AWS
Almost sounds like a paradox
Mrdarknezz··on German environmental groups file objection against Tesla gigafactory permit
Germany have not took any steps to increase their clean non-intermittent energy sources. Until they do they will be stuck with gas.
Mrdarknezz··on German environmental groups file objection against Tesla gigafactory permit
Well building a battery factory in EUs worst CO2 polluter kinda makes no sense from an environmental viewpoint. Better to build it in Sweden or France which have a heavy Nuclear/Hydro mix in their grid.
Mrdarknezz··on Apple’s renewable energy projects are helping to create 1.2GW of clean power
It'd be better if they'd start an energy company that produces hydrogen only from nuclear and wind instead. That way it would be sustainable and promote important sustainable energy sources.
Mrdarknezz··on Apple’s renewable energy projects are helping to create 1.2GW of clean power
Yes that is produced mostly by Natural gas. During 2020 the mix was ~99.2% Naturalgas and 0.8% wind. Producing hydrogren from naturalgas puts the CO2 footprint at around the same as coal since per kwh hydrogen you need to input double the amount of energy.
Mrdarknezz··on Apple’s renewable energy projects are helping to create 1.2GW of clean power
Pretty sure that an organization that pushes the idea that Gas is renewable and Nuclear is bad for the environment really isn't something we can trust in any issues relating to the environment.
Mrdarknezz··on Apple’s renewable energy projects are helping to create 1.2GW of clean power
People will just buy another phone? The total CO2 footprint will most likely be higher without the 12
Mrdarknezz··on Nuclear power must be well regulated, not ditched
If you want to talkt about emissions instead here is a great summary from the Swedish Life cycle analysis by energy source: Nuclear: 6g CO2/kwh Hydro: 9g CO2/kwh Wind: 13g CO2/kwh Solar: 24g CO2/kwh

This includes everything from construction to mining. The data comes from Swedens state run energy company Vattenfall LCA report https://www.vattenfall.se/foretag/miljo/epd/ and here is a an article that summarizes it https://blog.karnfull.se/blog/kaernkraftslogik-1-klimatsmart
