Trump officials cut nearly $8bn in clean energy projects in Democratic states Democrats and environmental groups slam move as β€˜sick political game’ and say it will drive up energy bills

As far as I can tell, this $8B in cuts to clean energy as part of the government shutdown is on top of the $13B from the pocket rescission.

"...this administration is not serious about American energy dominance”.

Big surprise.

ICE is going to apartment buildings without a warrant, breaking down the door of literally every unit, zip tying & detaining everyone inside, & arresting people for things that have nothing to do with immigration.

This is a 5 alarm fire. This is what a secret police force does.

ICE agents raid South Shore apartments; Trump says Chicago could become military training ground ICE agents raided a South Shore apartment building overnight as the city braces for a possible military deployment.

β€œABC7 spoke to Pertissue Fisher, a woman who lives in the building. She said ICE agents took everyone in the building, including her, and asked questions later….’They was bringing the kids down, too, had them zip tied to each other.’”

It can’t happen here, you say. But it is happening.

Drones, Helicopters, Hundreds of Arrests: Trump’s Immigration Crackdown in Chicago So Far

"Mr. Pritzker ... said the effort was calculated to damage and intimidate Chicago, calling the federal officers β€œjackbooted thugs roaming around a peaceful downtown.” He added that parents were afraid to send children to school and that small businesses were suffering."

Massive immigration raid on Chicago apartment building leaves residents reeling: 'I feel defeated' The Department of Homeland Security said federal agents with Border Patrol, the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives arrested 37 people in the raid.

"Armed federal agents in military fatigues ... pulling men, women and children from their apartments, some of them naked... Agents approached or entered nearly every apartment in the five-story building, and U.S. citizens were among those detained for hours."

Our latest results on the laminar-turbulent transition in pipes. Body forces acting in the fluid give a tricritical point once the body force is strong enough. Centrifugal force in a curved or helical pipe is an example. Bjorn Hof's experiments see these effects.

Tweet from the Department of Energy saying wind and solar energy is essentially worthless when it's dark outside and the wind is not blowing. Basically showing the DOE doesn't understand energy.

During the day yesterday in California, >75%of all electricity was produced by renewable #energy, including solar.
After the sun went down, half of all electricity STILL came from renewables, including wind batteries, hydro, geothermal, etc.
