Yes it is. This is why people are still researching it, bringing solutions rather than trolling everyone. This is how science works, if you don't know.
There are plenty of advances all day being published, including in recycling. If you don't agree, again, bring a solution better than this one.

Carlos Rossa @carlosrossa.bsky.social · 36m

We don't have "to cover the planet". PV works also on roofs and small installations if the problem is land usage. If you want to criticise something and be disrespectful to people doing their part by calling them a liar, try to know something about it at least.
Bring a solution, if you have one.

Nuclear? Interesting. I suppose that nuclear people already know how to manage the nuclear waste after years of usage. Or is it an issue for the next generations? Really, I'd like to know it. You must know that nuclear is really expensive nowadays right? I mean, maintenance costs, construction etc.

Carlos Rossa @carlosrossa.bsky.social · 9h

Yes but, how did you realise? That's the point.
Why according to your opinion everyone in wind and solar is lying? Do you have some profound research that supports it or is it just a matter of...opinion? I mean, your faith? If you're fact checking I suppose you're doing some real research right?

Carlos Rossa @carlosrossa.bsky.social · 18h

How did you realise it? Did you do some scientific research about it? So what's your alternative to generate energy without emitting too much CO2, technically viable today?
We all know that there are no 100% clean energy sources, as we've studied thermodynamics at least once in our lives.

It's not propaganda. It's real research. If you have a better solution, just tell the world about ir rather than be a conspiranoic reproducing outliers like "wind and solar propaganda". If you think you're right, publish it. Tell the world. Fight for it in a proper arena.
Or come back to X.

Nothing is 100% without consequence, but some alternatives are definitely better than others. You're talking as if nobody knew anything about this, but a lot of research is already being done on all of these topics. Science doesn't look at outliers. That's for MAGA people.

Considering that most large-scale PV plants are strategically placed in deserts or are integrated with agriculture, only a very small number of installations are considered environmental outliers, and. Deep-sea mining is unlikely given that recycling and reuse are expected to be more cost-effective.

The just-released IEA's Renewables 2025 report forecasts capacity will nearly double by 2030, but miss the COP28 target. Solar PV dominates growth (80%), with China leading the build-out. The USA forecast was cut significantly due to policy changes.

The main commercial barrier to establishing perovskite modules is their operational stability. A new material could be the key: at least on a reduced scale, a 25.8% efficiency was achieved with unprecedented 1000h operational stability at 65∘C.

There's no scientific consensus about it. But most of the scientists say that the solar cycle has a very low, insignificant impact on these variations. Maybe it's the primary force behind all of this and the anthropogenic forcing just exacerbates it? Maybe.

The first code, 4DV4.3, corresponds to 'Predicting Shading Losses in Photovoltaic Plants: a Novel Approach', to be presented by Mr. Daniel López Dalmau. The second code, 4DV4.4, corresponds to 'Backtracking 3D: a Novel Approach to Conventional Backtracking Algorithms for Improved PV Performance in Complex Terrains', to be presented by Mr. Joan Tomás Villalonga Palou. Both poster presentations are scheduled for September 25th, from 15:15 to 16:45.

This is an interesting point by the way that I'm thinking about lately. How you can explain big things based on observations on a small scale. The rupture point, the continuum if it exists, etc. There's a recent Perspective on nature talking about it.

Thanks for sharing. Interesting indeed. But the paper points out to another overall benefit, which doesn't exclude the benefits you mention.
