What could we achieve if we covered every roof, globally, with PV #solar panels? It turns out, 2/3 of global electricity needs.
I could add, the original paper doesn’t seem to take into account the cooling effect on homes by solar panels shading the buildings.
Here a CBC video breaks that down

Good news about our #pluginpv project in #Ukraine: “Yesterday we completed the installation of the panel: my husband fixed all the elements and ran the cables to the balcony.”
Our project partners from #EcoClubRivne are checking out how to install #solar on the #balcony. How to set ups such a system with a small battery, because there are lots of #blackouts in Ukraine, due to the destruction of the #powergrid by Russia.
Of course we also try to explore what landlords and gridoperators think and if they try to block small #pv.
Wir helfen gerade Menschen in #Berlin, #Dresden, #Leipzig, #Mecklenburg, #Frankfurt, #Wuppertal & anderswo bei Klagen um #BalkonSolar gegen den #Vermieter – habt ihr Beispiele wo #Solar am #Balkon problemlos klappte?
Bitte kommentieren. Damit wir auch positives hören.

In a first for the US, wind and solar produced more electricity than coal last year, according to a new report from energy think tank Ember. Coal fell to a historic low, generating 15 percent of the country’s electricity compared to 17 percent from solar and wind combined.

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.

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/
UK folk, a partial eclipse is happening on Saturday 29th March.
At approximately 10:08 GMT, the Moon will begin passing in front of the Sun, partially eclipsing it. Maximum eclipse, when most of the Sun is covered (30% to 40%), occurs around 11:06 GMT. The eclipse ends at 12:05 GMT. These times will vary by a few minutes, depending on your location. Stargazing locations (likely where people will congregate) can be found on https://gostargazing.co.uk/location-map/
Visibility forecasts for the next week can be found here: https://clearoutside.com/forecast/51.51/-0.13 where a green hour is good visibility, a red hour is "sorry, nothing to see".
Times are in GMT, this is the day before DST kicks in.
DO NOT LOOK AT THE SUN through any apparatus, you can be blinded. Purchase solar glasses from FLO if you don't own some already https://www.firstlightoptics.com/solar-filters/baader-solar-eclipse-observing-glasses.html
DO NOT USE A TELESCOPE OR CAMERA unless you have a sun filter or it is made for observing the sun (99.9% chance it does not).
Ooooh, man, did we have a stellar day for #solar energy production today! With electric heating, I usually don't get a day when I'm net positive until about a month from now. But after all was said and done, I'm up 12kWh despite it being between -5 and -9 Celcius for most of the day.
Economical, solar-powered system for converting municipal wastewater to green hydrogen and animal feed.

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.

UK Research: #solar farms can benefit #biodiversity in rural landscapes dominated by intensive agriculture in the UK. Especially when they are designed to allow plants to grow around the panels, and have hedgerows or trees in the margins. #EnergyTransition

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
