YouTube video by The Gravity Well with Jenny Yeremiy Stanford University Professor Mark Jacobson explains how carbon capture & storage is #greenwashing

Professor @mzjacobson.bsky.social of Stanford University explains how carbon capture and storage, the technology required to make any “decarbonized” pipeline possible, is a greenwashing scam.

Blue H2 hardly exists. Almost all H2 today is from gray H2 or coal.

Green hydrogen is available today, and its production is growing. Sweden's new steel plants are using green H2.

In any case, blue is almost as bad as gray H2

Despite electric heating in TX, TX burns 3.1x the fossil gas per capita as CA. In fact, all southern states burn far more gas/capita than CA

So they use far more electricity and gas per capita. Due to lack of conservation and efficiency measures.

www.eia.gov/state/seds/d...

That makes a difference primarily if the home is not insulated well, which is the problem. A very-well-insulated home won't use much energy even if it is big. The lack of efficiency standards in TX stands out here.

Some claim the high electricity use in TX and other southern states is due to electrification of heating vs use of gas for heat in CA & blue states

But TX burns 3.1x the fossil gas per capita as CA. All southern states burn far more gas/capita than CA

This phenomenon, where red states use far more electricity per capita than blue states, has been know for 40 y, as shown by Evan Mills and Art Rosenfeld in 1987:

escholarship.org/content/qt59...

It is due to the lack of efficiency standards and conservation programs in red versus blue states

No. This phenomenon has been know for 40 years and was pointed out by Evan Mills and Art Rosenfeld in 1987:

It is due to the lack of efficiency standards or conservation programs in red states versus blue states.

Correction. Third sentence should read: The 12 states with the highest per-capita electricity use are all red states."

(3/3) The good news is that efficiency measures work to reduce grid electricity demand. Along with rooftop PV, that is another way to keep electricity use low despite the growth in data centers, EVs, heat pumps, etc.

(2/3) The ratio of per-capita electricity use of the bottom-12 red states to the top-9 blue states is 2.60:1. In other words, these 12 red states use 2.6x the electricity per person as the 9 blue states.

Similarly, the per-capita electricity use of Texas is 2.67x that of California.

Yes. Corrected in a reply.

(1/3) Red states appear to intentionally waste electricity by not making efforts to reduce electricity use through better insulation, appliance standards, etc.

The nine states with the lowest per-capita electricity use are all blue

The 12 states with the lowest per-capita electricity use are red

CA and NV have DECREASED their year-on-year grid electricity demands by growing roof PV more than new grid demands (datacenters, EVs, heat pumps) have increased

CA has the 3rd-most data centers and by far the most EVs

Other states could take a lesson in how to avoid increases in grid demand

13 American states generated 49-120% of their electricity from wind, water or solar. Wind has become the dominant source of electricity in 8 states.

And before anyone says, "but CA has such high elec prices," the elec price increase in CA during this time was only 0.23 c/kWh vs a US avg inc of 0.75 c/kWh

TX increased 0.6 c/kWh
NV decreased 2 c/kWh

So, CA & NV decreased grid demand with roof PV & kept price increases lower than other states

New EIA data

From Oct 1, '24-Sep 30, '25, 13 states generated 49.7-121% of their electricity demand with WWS

Wind was #1 overall generator 8 in states (SD, IA, WY, KS, ME, NM, ND, OK)

Hydro #1 in 3 (MT, WA, OR)

Solar #1 overall in CA and #1 WWS generator in NV

The evidence keeps piling up that — contrary to popular belief — more clean renewables means cheaper electricity

11 of 12 US states with the highest proportion of clean renewables have cheaper than average electricity
