A HISTORIC MILESTONE: For the first time, solar power generated more electricity globally than nuclear, making it the world’s 4th largest power source.
In just 5 years, solar output nearly tripled—from 79 TWh (Apr 2020) to 233 TWh (Apr 2025). The energy transition is speeding up.

@KentStBaseball @Micah_RK1 I’m not the best video editor, but I was able to zoom in a bit, loop it once, and add audio from the Virginia Tech radio broadcast. (Best viewed on a computer or larger screen.)

Video shot at 30 FPS and thus the 3 consecutive still shots here are separated by less than 0.1 seconds!

The blatant, hateful, crude, vulgar, and outright racist language being used by the Republican Party at today’s rally should have no place in modern day politics. Our country and our people must be better than this.

Chart of the day: EV are leading to the reduction of oil demand growth globally. The future of EVs will determine the fate of global oil markets and much more.

Our latest General Chemistry lab-realistic simulation gets its first student use next week!

Students investigate the dehydration/rehydration of copper (II) chloride dihydrate, collect simulated data, & make qualitative observations that accurately mimic in-person lab results!
