Was already tried in the North Pacific off of Canada and seemed to go well, though obviously we need more info than just this video:

Biosolids! There's a lot of data out there showing that using HTC-processed biosolids in place of sand in bricks & concrete can cut down on energy use by 50%, and at 10% replacement could offset all of the emissions from cement production.

As always: we have the technology to make this happen. It's just a question off whether we have the political will.

Reply to comment by Tombfyre in Italian startup Energy Dome claims its CO2 grid storage batteries are cheaper than lithium-ion, and need no rare minerals, being made from just off-the-shelf steel components, water & CO2. It's opening its first 200 MWh facility in Sardinia in 2023 by lughnasadh
Great video on this here:
Seems so much more promising than other potential solutions, like compressed air.

They're not even keeping pace with New England, or the entire northeast outside of Pennsylvania. Texas absolutely should be criticized for that.
And selecting Austin as representative of the whole state is disingenuous for the obvious reasons.

Texas is 24th in solar installations per capita despite being smack in the sun belt:

It's growing, which is encouraging, but California's per-100k installations is 9x Texas's.

Flying into Texas is so depressing. So many rooftops, so much sun, so few solar panels.
And then every year we see so many hundreds (thousands?) of weather-related deaths there because they've let their grid go to shit.
EDIT: For some understanding of just how much Texas is letting their natural resources lay fallow, here you go:

Reply to comment by RipThrotes in Aeromine says they have solved many of the problems that have long made domestic rooftop wind power compare poorly to solar panels. They claim their "motionless" rooftop wind generators deliver up to 50% more energy than a solar array of the same price while taking up just 10% of the roof space. by lughnasadh

Article said about every 15 feet.

Toss in advanced geothermal and the land usage drops even more, as will the costs:
