There Is No ‘#EnergyEmergency
In the lawsuit, 15 Democratic states called Trump’s declaration illegal and said federal agencies were rushing permits for #fossilfuel projects
“Declaring a National #Energy Emergency,” directed federal agencies to speed up energy projects for #oil #naturalgas & #coal, excluding wind and #solar. It stated that energy production was not meeting the nation’s needs, even though #US production has been at record highs.

Drilling gear being stored in Texas in 2021. Energy production in the United States is at a record high.

@BNetzA Am Ende zahlt es wie immer der Verbraucher und Einspeiser vor Ort, weil die Lobbyisten mehr Einfluss haben.
Warum zahlt es nicht der Netzbetreiber aus meiner
weiterverkauften kWh? Und btw. Die Übergewinnsteuer aus den Coronajahren wurde auch nie erhoben. #amArsch #pv #solar

Pittsburgh International Airport, already the first airport in the US to be fully powered by a microgrid, is expanding its solar field in a nearby landfill.

The new solar project will generate an additional 4.7 megawatts of renewable energy. That’s enough to cut around 5 million pounds of carbon emissions annually. #solar #climate #ClimateChange #environment #news #pittsburgh

Electrek · Pittsburgh Airport is turning a landfill into a solar powerhouseBy Michelle Lewis

When they set out to make their power supply 100% green, Northwest leaders ignored the fact that the region lacks the wiring to deliver new sources of renewable energy to people’s homes.

Little has been done to change that, ProPublica and Oregon Public Broadcasting found.

Worauf wollen wir wetten, dass der Einzelhaushalt hier auf die Nase bekommt. Die Netzbetreiber kommen nicht hinterher mit den Smartmetern und ich darf es bezahlen. War ja klar.

DER SPIEGEL · Geplante Reform der Bundesnetzagentur: Solaranlagenbesitzer sollen künftig mehr Netzkosten tragenBy Benedikt Müller-Arnold

Took this thing out of a SunPower #solar generation monitor thingy. SunPower is alas now out of business, so this is probably headed to the landfill.

But those ethernet & USB-A ports make me wonder--is this maybe a single-board full computer that I could try to use like a #raspberrypi maybe? Anybody know?

A fine day for some solar astronomy and a fond farewell to AR4079

Our temporary observing setups are assembled on the base/floor of the planned observatory. The light orange bucket, at center, protects an empty electrical conduit that will provide utility power to a permanent pier that will be installed there. In the foreground is a table supporting a light shield for the laptop computer. The large tripod next to the table supports the white light imaging scope. In the background is the Sky-Watcher SolarQuest mount with our Coronado hydrogen-alpha solar scope attached.

We’re still doing open-air astronomy though we have a nice, solid, clean, and level space to set up our gear! This is the setup we were using today to record the sunspot at active region 4079 as it is about to roll over the solar limb/horizon. Fortunately, though it’s a very temporary setup, the portable gear we use for casual solar imaging is fairly easy to set up.

From an unusual vantage point, a picture of the solar setup used today to record the passage of active region 4079 toward Sun’s horizon. The red object is the planetary camera.

We continued experiments to determine what gear will work together for imaging. There were a few surprises and there’s need for more experimentation. What we settled on for today’s solar efforts is pictured above and includes: Askar 103 APO telescope, Meade LXD75 Goto Mount, TeleVue 2X Barlow, Baader Planetarium Safety Herschel Wedge, and ZWO ASI678MM monochrome planetary camera.

The sun as it appeared at 11:32 AM EDT on May 10, 2025. Sunspot/Active Region numbers are labeled in this image with AR4079 very near the solar western limb or edge.

Although the sky was clear, seeing was a bit shaky so once again, sharpness wasn’t what we’d like. Still, in all, we got the shot we wanted and learned a few things about our astronomy equipment. Also, the sky was blue, the air was pleasant, and birds were singing, so not a bad way to spend a couple of hours.

A closeup view of the sunspot at AR4079. There is a bright line splitting the dark central umbra of the sunspot, the gray penumbra radiating in filaments around it. White cloud-like areas surround the sunspot, especially to its north; called plage, they are associated with areas of concentrated magnetic field.
