  • Corporations are responsible for a vast majority of the waste

    I don’t really understand this recurring theme in this context, Can someone explain to me why this is relevant?

    Afaik, this isn’t a discussion in my country, since most people (should) know that already. This article triggered me, beacuse I want to lower my personal energy usage. Many companies in Europe who were energy wasteful and high energy users (like some chemical, steel, or aluminium plants) needed to close after the Russian invasion in 2022 and the then extreem high energy prices. Those that survived, are still struggling to this day.


  • What was the source of that energy loss?

    No idea tbh. I tried to figure it out myself first, then I had two electricians independently checking it.

    And their conclusion was that they didn’t know, and that the 5% was sort of normal. I even had my electricity meter recalibrated by the grid company. I was afraid somone was taping, but no… It still could’ve been the electricity meter ( which was like only 10 yo, I looked up its specs and readings). Humidity, Magnetism and Radio signals might effect the readings, under circumstances. So to be" safe", I have now a newer smart electricicity meter.



  • Even if it is, this pales in comparison to corporate energy use.

    Yeah I agree, I later saw that the article focuses on households, which usually account for like 20% of a countries energy usage.

    Honestly, I associated the articles headline and photo to energy losses in the Grid by keeping energy online. So Grid losses, and the application of smart grid functions will save way more then 5% of a ca 20% household energy usage. In this article they talk about a 4-5% overall country gain, for example











  • I’m very ignorant on this subject, but couldn’t you just sell excess to grid and get it back for a minimal markup?

    Sure, but it depends on the incentives in your country. Afaik, excess energy could be sold, but you’ll have to checkout your local incentives and energy suppliers for specifics. In most parts of Europe, the are scaling down the prices for excess energy. Therefore, battery systems are being forwarded in some cases as sort of solution for solar panels maintaining like ca. 80% +? integrity efficiency over 20 to 30 years.

    For example, I read that in The Netherlands the solar panel market has crashed completely or is crashing. Note here that saturation of the market ( many existing solar panels) can also cause that.

    You need to find out;

    1. energy usage
    2. insulation options and materials
    3. costs /benefits
    4. energy contracts and energy incentives.
    5. check out current physical electricity wiring and fuses in the house
    6. DIY or professional?
    7. budget etc

    TLDR: dont buy solarpanels if you want to be rich. And buy them according and after you’ve done everything possible to insulate your house, whether in the colder or warmer climates. The efficiency, added value, and comfort reached by insulation outweighs everything else. Then , after doing that, check your kwh usage, and buy solars according to that.

    Hope this is helpful, but seems you need to go outthere and do some exploration on the topic.

  • How big a battery would we need in order to be completely self-sufficient?

    Exactly. Haven’t read all details of the link,so I react your comment, and have immersed myself a bit in this earlier.

    You need to change your way of thinking and energy usage. Start with your daily energy supply and then change your energy consumption pattern to day time use Then, with for example a dynamic energy contract or if you can spare solar energy, buy or store cheap electricity in your storage ( battery ). The energy management system ( charge / uncharge and which cells) is very important.

    Also, realize that battery life is tied to charge cycles and need replacing like every 10 years when talking about the better quality Lithium battery . Sodium systems could and maybe should be used in parallel, if you want more storage, safety and longevity (20 years).

    It is yet all quite expensive, though imo having a half day reserve like 5 - 10 kwh, battery, would already create more independence (at around € 3K to € 10 K in Europe) .
