This is a great example of how various mixes of clean sources can keep emissions low. Compare that to Germany, where solar and wind cannot provide the power needed and coal and gas have to fill the gap, at the expense of many times higher CO2 emissions.

Epstein’s economic power among academics was made possible by a capitalist system that makes higher education dependent on the charity economy rather than a public good supported by taxing the rich

Yes! Let’s go. California should do the same.

Bubble map of election results for Prop 50 in California. Size of bubble indicates vote count and color represents vote choice.

I much prefer bubble maps for election results instead of county-shaded maps. This one from PBS on California’s Prop 50 is a great example. Land doesn’t vote. People do.

How does the land use of different electricity sources compare? All energy production takes up land, but which sources use the most land, and which use it most efficiently?

And ignore nuclear’s tiny footprint!

Law enforcement officers should never cover their faces when making arrests or conceal their identities (unless they are working undercover). They work for us. We have a right to know who they are. These face coverings are frightening & unAmerican, as though they're ashamed of what they're doing.

Happy Earth Day! @mothersfornuclear.bsky.social was founded on Earth Day in 2016 to change the conversation around nuclear energy.

I see it. I have lived it. 83 years ago, the U.S. government turned upon a group of its own citizens and residents and sent them to internment camps without due process. I was there among them. American fascism is back. It is here. It is now.

In 1976, California banned the construction of new nuclear plants. But now, the bipartisan Assembly Bill 305 is moving through Sacramento to legalize nuclear again.

Bay Area: come out to the Rave For Nuclear Energy on 4/20 to celebrate this legislation!

What makes this visual even more stunning is that it was made possible by people who said their #1 concern when voting was the economy. What idiots.

Everyone wants there to be a grand scheme behind all of this but the terrible truth is that extremely stupid people are in charge and they have a fanatical devotion to wrong, childlike concepts of society and economics cooked up by right wing radio hosts in order to sell tainted dietary supplements

RIP to a talented actor. Not mentioned in most of the headlines are two other classic roles - Chris Knight (Real Genius) and Mad Martigan (Willow)

Among the material devastation to everyday people, Senate Dems have now blown a hole in their ability to work with the House.

We had an agreed upon plan, House took immense risk, then Senate turned around midway and destroyed it w/ a fear-based, inexplicable abdication.

They own what happens next.

If trickle down economics was sound economics, Americans would be thriving right now.

It’s. Not. Trickling. Down.

It’s been nearly FIFTY years.
