Even solar?
Discussion
Indeed. Even solar.
Energy is neither created nor destroyed.
Solar PV arrays convert solar radiation into electrical energy, but this process is not 100% efficient. Some energy is lost as heat during the conversion process.
Entropy.
In the context of solar PV arrays, this means that while they convert solar energy into electrical energy, they also increase the entropy of the system. The overall process is not perfectly reversible, and there are always losses associated with it.
Energy Payback Time.
The manufacturing, installation, and maintenance of solar PV arrays require energy inputs. The energy payback time is the time it takes for the solar PV system to generate the amount of energy that was used to produce it. This means that the system does not provide "free" energy immediately; it takes time to recover the initial energy investments.
Agree, but it does produce more energy than the cost (to us)?
Generally, you are right , law of physics, energy just changes state. Another proof of creation, there is an external energy input
You have to think of ALL of the energy inputs to produce a PV panel.
Producing a photovoltaic (PV) panel is an extensive process that encompass multiple stages. It begins with the extraction and processing of raw materials such as silicon, aluminum, glass, and various metals, which involves mining and refining operations that are energy-intensive. These refined materials are then transported to manufacturing plants, where they undergo further processing to create silicon wafers, solar cells, and finally, assembled into PV modules. Throughout this supply chain, transportation between stages consumes additional energy.
The production process also requires significant human labor and various chemical reactions, each contributing to the overall energy footprint.
Additionally, the end-of-life management of PV panels, including recycling or disposal, adds to the energy inputs.
It is highly doubtful that the output total of a PV panel closely approximates the overall energy inputs before the system degrades into disuse.
It is clear in my mind, that it makes more sense to hqve a centrally peosuced power source. However, as we have decended into the final stages of a scam economy. It is now every man for himself, so the tech makes sense.
I do agree.
PV is viable. You’d have to admit though, that y he assertion that PV panels create free energy is absurd.
They are two entirely separate conjectures.
