re: If Texas's central grid only relied on solar & wind energy, would anyone have electricity?

True. But it's next to zero now as demand spikes.



How do you figure it's down to zero?

Based on that graphic, it looks like it's still on top of all others...and always has been.

Then again, I don't like that graph, so maybe I'm reading it incorrectly.

The Y axis is the total output in the grid. Not the total output per source. Wind went from the largest producer 12 days ago to near 0 today.

You are. The color is each items contribution. If there is a sliver of color it is less of the total.

For example on Feb 8 wind was the largest supplier, on the 11th it was almost at 0.

On the 8th of Feb total supply was ~40,000 megawatt hours which was supplying all everyone needed (the storm hadn't hit yet).

On the 15th of Feb total supply was ~70,000 megawatt hours and there were a lot of people without power.

Total supply went UP 30,000 megawatt hours with Nat Gas doing most of it, but because of the crazy cold temps it wasn't enough.
