What if we put solar panels on every roof in the world?
Scientists set out to explore the impact of covering every rooftop on Earth with solar panels.Their research found that swapping traditional energy sources for rooftop solar could actually cool the planet — lowering global temperatures by up to 0.13°C.

Aren't there extension cables for these solar panel connectors? I only find "MC4" cables, which seem to be only the connector on the receiving end but not the panell side. I need an extension for the panel side though. as 2 of the 4 panels are further away.
Do those extension cables even exist, or isn't this meant to be due to some frequency issues? Should I instead get another one of those cables with 4 connectors put them in a row if possible? (Seems to be possible?)

Hi liebe #DIY und #Balkonsolar Community, vor Kurzem habe ich hier mein Vorhaben geteilt, eine Terrassenüberdachung selbst zu bauen und Module darin zu integrieren.
Danke an alle, die mit Tipps und Links geholfen haben!
Jetzt ist es soweit: Die Planung ist abgeschlossen und die Materialien sind da.
Ich werde die Schritte, die mir bei der Vorbereitung geholfen haben, mit euch teilen. Beim Aufbau werdet ihr "live" dabei sein

#FunFactFriday: If every suitable roof in the world was covered in solar panels, it could provide 65% of global electricity, allowing for almost all fossil fuel-based generation to be replaced. Are you interested in getting rooftop solar? News Source: https://www.pv-magazine.com/2025/03/13/rooftop-pv-could-cover-almost-two-thirds-of-the-worlds-electricity-study-says/
In den #USA übertrafen #Solar- und #Windenergie 2024 erstmals #Kohle als #Energiequelle.
Ihr Anteil stieg auf 17 %, während Kohle auf 15 % fiel. Trotz steigender #Stromnachfrage sanken die CO₂-Emissionen.
Während Präsident #Trump auf #fossileEnergien setzt, zeigt der Trend klar Richtung #Erneuerbare. Auch in #Deutschland erreichte der Ökostrom-Anteil mit 59 % einen neuen Höchstwert.
Our PV+battery has been up about little over a week now. Today was hot and sunny; the first day of a 4-day heatwave and topped out at 31C while staying pretty humid.
We had AC on in a couple of rooms most of the day, using 26kWh of energy for all activity. The PV array produced nearly 44kWh of energy. We consumed 16kWh from the battery. At about 4:00pm, the battery was full.
Presently, the battery is discharging as we consume electricity from it, and it exports to the grid. Over the day, and across two price spikes we've exported 23kWh of energy. It's clearly not going to be any less in coming days.
On less sunny and hot days, it looks like we'll generate around 2x our consumption. On hot days like this, it will be even more (
Yes, it's going to take a handful of years to recover the outlay, but at this rate, we’ll both completely offset the cost of electricity supply to our house as well as earn enough FiT to offset a significant proportion of electricity supply for our guest cottages.
In NSW (and I believe other states), there are significant state government rebates on batteries alongside federal rebates on PVs. If you have the chance to invest in solar+battery, now is as good a time as any.
Interesting. Everyone has kind of assumed that putting big #solar arrays in a farmer’s field (so-called “agrivoltaics”) would probably further harm biodiversity. Someone finally tested that assumption and found out that the opposite is true: a well designed solar array allowed birds in much greater number and variety to live in the field compared to crops growing without the solar array.
Edit: see caveat in replies.

Wonder why wind, storage & other climate techs matter in the current climate?
Here's a live view of Texas's electricity mix: wind tops the list, energy storage plays a key role. The second biggest source: solar. (There's a CKI deep-dive for solar, too.)
Wind, solar & batteries don't dominate Texas's grid because of state-level policies & regulations. Quite the opposite.
The Cabinet has approved a new bill that aims to prevent the circulation of stolen copper cables and other valuable metals, particularly those taken from solar power facilities. https://www.japantimes.co.jp/news/2025/03/11/japan/crime-legal/metal-theft-law/?utm_medium=Social&utm_source=mastodon #japan #crimelegal #renewables #energy #solar #electricity #theft #cabinet #metals
In the weeks since President Donald Trump has taken office, he has pushed to unleash oil and gas production and has signed executive orders halting the country’s transition to renewable energy. https://www.japantimes.co.jp/environment/2025/03/11/energy/us-nuclear-site-solar-farm/?utm_medium=Social&utm_source=mastodon #environment #energy #us #nuclearenergy #renewables #solar

Guten morgen, wer wohnt zur Miete und hat ein Balkonkraftwerk installiert. Ich hatte da ein bis zwei fragen.
Interview in #SWR1 mit unserem Vorstand @sbamueller : #Steckersolar ist einfach und geht ab 300€ los.
Daher: einfach machen.
Peer-to-peer energy trading + cheap solar & storage = millions of people lifted out of energy poverty.

Milestone: 51% of all electricity produced in the Netherlands last year was from renewables! In 2015, it was only ~12%.
Nuclear's share last year was 3%, leaving 46% for fossil generation (mostly gas).

A green energy auction system that has turbocharged India’s solar and wind growth is at risk of being upended by the country’s cash-strapped utilities. https://www.japantimes.co.jp/environment/2025/03/10/energy/india-utilities-green-energy/?utm_medium=Social&utm_source=mastodon #environment #energy #india #energy #fossilfuels #solar #renewables
@Lapizistik Natürlich nicht. #ITER dient der #Grundlagenforschung, und es geht dabei vorallem darum jene Technologie zu verstehen.
Vorallem wenn wir nichtmals ansatzweise #Solar & #Wind-Potenziale angezapft haben...
Das hier ist ca. 50 m vom Haus entfernt und liegt im sogenannten "Außenbereich":
Das ist also kein Bauland, aber durch die Bahnstrecke hinter dem Grundstück darf hier dennoch Solarstrom gewonnen werden 
Das das so ist, habe ich hier entdeckt:
https://www.energieatlas.nrw.de/site/karte_solarkataster
Auf der Seite kann man Solarpotenziale auf Freiflächen anzeigen. Durch die Bahnstrecke liegen wir in einem "privilegierten Infrastrukturbereich", der das möglich macht.
