The hardware simply has to be put into place. Something way over the head of a twerp like you. Maybe you could go sit out in the sun for a few days and dessicate yourself to prove to us all how the sun doesn't work.

The winds dropped out during the recent heat wave and they lost about 20GW, causing overload on the non-renewable generation capacity. They probably had the backup capacity to cover it, but it couldn't react fast enough. The really big suff takes hours to spin up, and when the load fluctuates on the order of GW's per hour, they can't track it. They have so-called gas powered peaker plants that can track it, but capacity of those is limited to smaller fluctuations, few hundred MW. https://www.houstonchronicle.com/business/energy/article/Texas-has-enough-sun-and-wind-to-quit-coal-Rice-13501700.php

No semiconductor > solar panels in those.https://en.wikipedia.org/wiki/List_of_solar_thermal_power_stations doesn't include any in Texas. https://en.wikipedia.org/wiki/Ivanpah_Solar_Power_Facility is in California and doesn't seem to have bothered with thermal storage - they burn gas every morning to melt the molten salt heat transfer medium. Pretty much everybody else seems to have nice big insulated tanks to keep lots of hot molten salt around to generate power after dark. The latest generation of solar cells seem to become cheap enough that some of the thermal solar systems have been ripped out and replaced with photovoltaic devices, but big insulated tanks of molten salt seem to be tolerably cheap energy storage systems. -- Bill Sloman, Sydney

They don't react to new opportunities all that fast. For every entrepreneur that will pounce on a new opportunity to make more money, there seem to be about twenty complacent twits who think that business as usual is just fine, and go out of their way to inconvenience unexpected=unfair competition.> And just about no utilities are > buying "storage gear' stupid, for obvious reasons.You need a fairly high renewable component before you need it, and if the Australian experience in South Australia is anything to go by, the utility companies ramp up the renewable content until they run into trouble, and only then buy the fast battery-based storage gear that can handle the rapid fluctuations in generating capacity. The obvious reason they wouldn't buy it would be stupidity (or at least inertia) and you'd know all about that. -- Bill Sloman, Sydney

They are too happy with oil to use solar. I guess Texas is like the UK, doomed. -- Rick C. + Get 1,000 miles of free Supercharging + Tesla referral code - https://ts.la/richard11209

What happened was their wind power, which normally runs at 20GW, a significant fraction of their total capacity, dropped to nearly zero during the recent weather.Yeah, there is no correlation between wind and the sun shining. In fact, it may be an inverse correlation. I'm sure Bill can tell us about that. My experience with ground level wind is that sunny days tend to be calmer, in particular toward the late afternoon when energy usage is peaking. But that's ground level wind as felt by boomerangs. Don't know what's happening at 100 - 200 feet. Certainly solar has some advantages and the correlation of power output with insolation is one of them. -- Rick C. -- Get 1,000 miles of free Supercharging -- Tesla referral code - https://ts.la/richard11209

In the US alone there are 23 GW of capacity. A single 3 GW facility has an energy capacity of 30 GWh.
