I paid 14ct/kWh before the war, thanks to having a combined heat and power plant and i have an old gas contract that guarantees me a gas price of 5,3 cent/kWh till the end of 2023. I am not sure what i will pay then since i will have solar and pv on my roof till then.

Yes, i wrote that PV is an good investment, but it is not free. The 28ct/kWh was not really competitive price before the war. Now, it is.

If your bought the oil for 2000 Euro and thanks to the energy crisis, it cost now 10.000 Euro, you also save money.
But i understand now what you mean. You are right, it is a different view on the same thing.

I gave you an example. If you have an big oil tank and fill it full, you pay many years nearly nothing till it is empty you and you need to fill it again. It is totally stupid to say you have free energy, only because you paid the cost upfront and than many years nearly nothing.
This is the same for solar. You pay the cost upfront and then many years nearly nothing and than you pay again a big bunch of money to renew the parts of your system. Yes, like when you pay upfront to fill a big oil tank, you can think a few years, you get your energy for free, thanks to not getting a bill for a few years. But it is dead wrong.Hint: I have pv on my roof and i am not able to get drunk enough to think one second that i get the energy for free. Maybe i am not the right consumer, or maybe i have reality on my site?
The right thinking is, that you have energy cheaper than your neighbor without pv.

You mean the consumer that has no clue about economics?
You don't live for free in your own home. You need to invest in the preservation of it, or you have no house after a while. The same with photovoltaic. The components of your pv system have a finite lifetime. It will break down if you not renew parts of it all the time.
Here is a quote of a study from the fraunhofer institute from germany: In 2040, the electricity production costs are forecast to be between 3.58 and 6.77 cents/kWh for small PV roof systems and between 1.92 and 3.51 cents/kWh for ground-mounted systems. From 2024, the electricity generation costs of all PV systems (without battery storage) will be less than 10 cents/kWh. https://www.ise.fraunhofer.de/de/veroeffentlichungen/studien/studie-stromgestehungskosten-erneuerbare-energien.html
Quote: 'Fraunhofer Society for the Advancement of Applied Research' is a German research organization with 76 institutes spread throughout Germany, each focusing on different fields of applied science (as opposed to the Max Planck Society, which works primarily on basic science). With some 29,000 employees, mainly scientists and engineers, and with an annual research budget of about €2.8 billion, it is the biggest organization for applied research and development services in Europe. https://en.wikipedia.org/wiki/Fraunhofer_Society
But i am sure that they only need to talk to you and you can convince them, that pv energy is for free after a short time. Sorry, but you are wrong.

>So size the system a little bigger than you need.
How do you do this, if you already used your whole roof?
Like i told you, the prime cost in northern germany for PV are around 12cent where i live. This was before the war. Now it should be around 15 cent.

Are we having a conversation about "solar is free" or about "solar is a good investment"? Thanks to the war, our energy cost rose from 28 cent per kWh to 45 to 60 cent per kWh form an energy supplier. Having photovoltaic on the roof is an awesome investment.

The 10 cent per kWh for photovoltaic and 28 cent per kWh for energy from storage is the cost over the lifetime of the system. Many things in your PV system will degrade. Mainly your storage and your inverter. But also your PV modules. In 25 years your modules degraded and new modules are much better. It will be more economical to change them.
When somebody buys an oil tank and oil for 9000 euro, nobody will think that he will then get his house warm for free thanks to not having a yearly energy bill. Everybody understand, that some day, he must buy new oil. This is exactly the same with an pv system, but you don't need to buy oil but inverters, storage and modules over and over again. Why is this so hard to understand? There is no free lunch.

>Yea this headline is horseshit in so many ways. First solar is always cheaper... because its free.
I never get "solar is free" talks. It is only free if you ignore everything that is needed to use it. If you think like this, gas and oil is also free, because they are only condensed energy from the sun.
Back to reality. If you have PV on your roof, your cost per kWh is near 10 cent in northern germany . If you have PV storage, your cost is near 28 cent per KW out of your storage. This is not free.
The cost for gas before the war was 5,3 cent per kWh. Thanks to the war, we are now up to 16,8 cent.

Reply to what are you waiting for ? by rixtil41
I wait for a human race that uses a better money system than the current one. The current one will kill us. See the money syndrom from helmut creutz: http://userpage.fu-berlin.de/~roehrigw/creutz/geldsyndrom/english/
And the natural economic order from Silvio Gesell: https://www.silvio-gesell.de/the-natural-economic-order.html
But to the mind uploading. I think mind uploading is totally stupid. This is a copy process. The thing that you uploading is not you. Why would anybody want this?
I don't wait for AGI, but for AI that helps to boost the health span massively.

Reply to comment by OfLittleToNoValue in Mindfulness-based attention training vastly improves the focus and emotional regulation of high school students by TimTars
The problem with this is, that it is only an intellectual concept when you tell it. How do you noticing without judgement? I could also tell you, that mindfulness is when you feel green. You understand the concept of green, but how do you feel green? Telling or knowing that you need to accept without judgement is practically worthless.
Your unconscious permanently judge its environment and it doesn't care what your conscious intellectual thinks. It still functions in the normal reaction patterns. If something is nice, it wants it and want to keep it. If something is bad, it wants to change it. This reaction pattern needs to change.
The key to know is, how do you train your unconscious to break the lifelong trained reaction patterns? One of the best ways is the vipassana meditation that is attributed to Buddha.
Sit still and make a body scan. The reason for this is, that your unconscious always is conscious about how your body feels. And when you make your body scan, your conscious and your unconscious are on the same place at the same time. Now sit still for an hour without moving. This is uncomfortable and your unconscious want you to move, but your conscious stops your movement. This is the situation you use to train your unconscious to understand to not judge a situation is better than wanting something. If it wanting you to move, it gets more uncomfortable than accepting the situation.
The best way to learn this, is to do a 10 day vipassna retreat, where you meditate 10 hours a day. A 10 day retreat let you reach a practice that is impossible for most to reach in years. They have three times a day a sitting of strong determination in a group where everyone tries not to move for an hour while doing a body scan.
The hour starts with singing and telling you what to do. Than there is silence. In the hour, you only scan your body. Start with the top of your head and try to feel something. If you feel something, move further till you scanned trough your whole body. When you reach your feet, do the same in reverse. When you are in some part of your body and you get a strong sensation in an other part of your body, ignore it. Do your scan without jumping from strong sensation to strong sensations. Don't move, no matter what. Your Eyes should be closed the whole time. This hour is uncomfortable and your unconscious wants you to move. This makes it more uncomfortable. The hour ends with singing for a few minutes (you don't sing).
After some time, you are so sensible to your body feelings, that your conscious and your unconscious feels at the same time that wanting to change the situation makes the hour worse. When you want the hour to end and wish that the singing starts, you instantly feel how your situation got worse. When you stop wishing the hour to end, it gets better. You also feel, that a uncomfortable situation is not uncomfortable all the time. Everything changes all the time. This is when you unconscious learn to accept without judgement.
But i can you tell this, and it will do nothing to you. I can not walk the way for you. Everyone needs to walk the way for himself. It stays an intellectual concept for you and your unconscious still will react within its trained reactions patterns, till you start to teach it.
