interesting article on local solar power

arstechnica.com/science/2025/0

"39 panels have a capacity of over 20 kilowatts—enough to power just one large, energy-intensive American household but more than enough for the lightbulbs, cooker plates and fans in the 180 households in Mbiabet Esieyere and Mbiabet Udouba."

not sure that have their numbers right but the point is still valid.

It good to see democracy take hold, here its the literal spread of power.

Trump moves to gut more agencies, targeting Voice of America, libraries, clean energy and National Monuments

Trump has signed an executive order seeking to eliminate several additional federal agencies, including one that oversees the federally funded media outlet
⭐️Voice of America (VOA),
🔥testing the limits of his authoritative power as he seeks to shrink the size and scope of the federal bureaucracy.

One order signed Friday night calls for the agencies
— some of which are focused on #minority business enterprises, #museum and #library services and #homelessness prevention
— to “be eliminated to the maximum extent consistent with applicable law.”

It also instructs the heads of agencies to “reduce the performance of their statutory functions and associated personnel to the minimum presence and function required by law,”
and submit a report to the Office of Management and Budget director #Russell #Vought confirming full compliance within seven days.

A second executive order revoked 19 executive actions signed by President Joe Biden that promoted #clean #energy and environmental goals.

The order terminates proclamations of #national #monuments created by Biden
and ends the use of the Defense Production Act to expand the U.S. manufacturing of clean energy technology
(including mandates for electric heat pumps and #solar #panels),
among other Biden-era policies

The Washington Post · Trump moves to gut several agencies, targeting Voice of America, librariesBy Brianna Tucker

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?)
#solar #electronics

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.

#GolfCourses Use More Land Globally Than #Solar or #WindEnergy

Story by Mihai Andrei, February 25, 2025

"The land use of #RenewableEnergy is often criticized in public and political debates. However, a new study shows that something as frivolous as golf courses use up more land globally than solar or wind energy. Golf courses, which often serve a small number of #AffluentPeople, are also terrible for the #environment and use up a lot of #water and resources.

Competition for space

"The lush greenery you see on golf courses is a well-maintained lie. Golf courses use enormous amounts of water — sometimes in regions already facing shortages. Maintaining that flawless grass also means heavy reliance on #fertilizers and #pesticides, which seep into local waterways, harming# wildlife and #polluting #ecosystems. To make it even worse, golf courses are apparently competing with renewable energy for space.

"Every acre we allocate to one use is an acre less for another. Currently, more than 38,400 golf courses span the globe, occupying vast stretches of valuable land. Surprisingly, researchers from Germany’s Forschungszentrum Jülich found that countries (especially richer countries like the US, the UK, and Canada) dedicate far more land to golf courses than to #SolarFarms or #WindTurbines.

"Let’s put this into perspective. If you take the golf courses in just the top ten golfing countries and convert them into renewable energy, you’d get an extra 842 gigawatts (GW) of solar or 659 GW of wind capacity. And to put that into perspective, that’s more than the entire quantity of renewable energy these countries produce and are forecast to have for a few years.

Replacing golf courses with something more useful isn’t a new idea, it’s already happening in some areas. In Japan’s Hyogo Prefecture, an entire golf course now hosts 260,000 solar panels, generating 125 gigawatt-hours annually. Meanwhile, in South Korea, 'screen golf,' indoor simulated golfing experiences, provide a popular, space-efficient alternative to traditional courses."
