Perhaps we should keep reminding everyone that utility solar and onshore wind are now the cheapest technologies for electricity generation!
And they are the fastest to bring to market!

Look at how much electricity generation from wind and solar increased in Texas from 2007 to 2024. And, still, our electricity costs are among the lowest in the nation!

Between 2007 and 2024, electricity demand in Texas increased by 51%.
In the same period, electricity generation from wind and solar increased from 3% in 2007 to 34% in 20024. Most of the new demand was met with renewable sources!
Do we want to halt the growth of solar, battery storage, and wind?

Texas, where is our electricity coming from?
Yesterday (10/14/2025), 41% of our electricity came from solar (32%) and wind (9%).
Do we really want to stop the growth of the energy sources that keep our ACs running and our lights on??

"The Chase" was the first of his films I saw in the late sixties.
Redford, Fonda, Brando, and Arthur Penn at his top, weaving masterfully the themes of racism, power, civic apathy, and injustice that simmer in a small Texas town.

2/2 One of the first tipping points may be the collapse of the Greenland Ice Sheet, which will be triggered by global warming levels below 2ºC. We are at or approaching 1.5ºC.
Loss of the Greenland Ice Sheet will cause long-term sea level rise by almost 23 ft!

But, but, but, are these dudes so out of it that they don't even care about their money? Coal is the most expensive way to generate electrical power! Twice as expensive as solar or wind... And the dirtiest in terms of everything, not just CO2...

Washington Post past glories...
In 1971, Katharine Graham, owner and publisher of the Post, ignored her male-dominated board and Nixon's friends and continued publishing the Pentagon Papers after the NY Times was forced to stop.

In 1945, Bush published the report "Science - The Endless Frontier" that distilled the lessons of wartime into proposals for subsequent federal support of science.

Remembering Vannevar Bush this week.
Bush headed the U.S. Office of Scientific Research and Development (OSRD) during World War II, helped establish Federal funding for science and engineering as a national priority during peacetime, and was behind the creation of the National Science Foundation.
