Events of extreme low energy production are expected to increase even in optimistic climate change scenarios, affecting at least one-third of regions. In this context, PV stands out as the most reliable renewable energy source, provided that climate goals are met.

Monocrystalline silicon solar cells hit 50–60% efficiency at 30–50 K, beating the Shockley–Queisser limit by suppressing thermal losses. This could potentially power future lunar mining robots and deep-space probes.

Surpassing Shockley–Queisser Efficiency Limit in Photovoltaic Cells - Nano-Micro Letters
The Shockley–Queisser (S-Q) model sets a theoretical limit on the power conversion efficiency (PCE) of single-junction solar cells at around 33%. Recently, a PCE of 50%-60% was achieved for the first time in n-type single-junction Si solar cells by inhibiting light conversion to heat at low temperatures. Understanding these new observations opens tremendous opportunities for designing solar cells with even higher PCE to provide efficient and powerful energy sources for cryogenic devices and outer and deep space explorations.

Just prove your point, "fact checker."

Your vision is limited by the whole thing.
Or, if this is the problem, we could keep burning fossil fuels until we find another energy source.
Just don't be a troll and be more respectful of people you don't know. Don't be a dead weight on the earth spreading a fool's opinion.

Consider the ratio of power to land required. For example, a wind generator is better than solar. But it's not just a matter of how much power is produced, and you know it.
Nuclear? Yes, it's intermittent, occupies less land, etc. But what about the costs? The wastes?
October 9, 2025 at 3:58 PM
You've been ignoring the core of the question since the beginning. You had to prove your point, but you couldn't. We all know this is not propaganda; it's science. You believe the opposite, but you can't prove it. You just bring images, or in other words, it's just your opinion. Where is the proof?

He won't.
But, just in case, he should have the opportunity to show it for a bigger audience like the science and energy sky feed. People who, according to him, reproduce wind and solar propaganda like parrots. His moment to prove that all of us are wrong.

By the way, the onus of the proof is yours. With numbers, real science. Not photos, opinions, outliers.
By the way, even wind people say something about the ratio power/land against solar PV. The difference is that they're just kidding, not being a fool like you and your "big knowledge".
