Need to have solar farms on top of all data centers.

No joke, dead serious. Warehouses too. Really dumb to just take up open land for them, unless it's in the middle of the desert.
I'm all for it, but aren't a lot of those solar farms hundreds of acres? I'm not sure how much scalability is a factor, but I'm guessing it's a pretty big consideration. Also they'd probably have to supe up the building span ratings considerably?

Yes there are solar farms that are hundreds of acres but there’s also quite a few that are 20-30 acres and even smaller.

Which is precisely where a lot of them are - in the desert in west Texas, NM, Arizona, California.

Solar systems are quite heavy, so any data center that would have a solar rooftop on top would need to be a really strong structure. So, the capacity to hold solar needs to considered during design of the building.

Some farmers lease their farmland to the utility for 10-12 years, the typical useful life of a solar farm before it has to be repowered.

It would take solar coverage of about the size of Lake Michigan to power the entire US.

Really depends on where they are. Lots of places in the US just aren't good candidates for solar right now. The payback period is so long, that when combined with the potential for hail or wind damage (plus the uncertainty of the original owner being in the building for 15-25 years and what kind of value it will produce in resale), it just doesn't look like a good use of capital. Basically the southwest and Hawaii should be covered up. And everywhere else is pretty marginal.

Grand Gulf was designed to have a second reactor anyways. Time to build it.
I may be imagining things, but I think Entergy was starting the process back in the 2000's to add another reactor at Grand Gulf but dropped it when the financial crisis hit?

sucks for those of us who like pollution
The Metro Center in West Jackson would be a prime location. Not only the parking lot but the roof. It's just there empty.
mount 'em on shocks so when the roof collapses from disrepair we still get our KW

Well they aren’t doing that. They’re putting them all around the south.

Because they are still getting 30% of the capital returned to them in the form of a tax credit.

I should have mentioned that I was talking about without subsidies and looking at it from a societal perspective, not whether some taxpayers can come out ahead at the expense of other taxpayers. Once the 30% tax credits expire I think next year (although I think construction has to be underway this year?), you will probably see those stop until there is a change in economics, either because of much more expensive electricity or because of a breakthrough that reduces the cost of solar.

Parking lots and garages.
I have read a few articles that lay out the cost differences, and engineering reasons why, there aren't a lot of parking lots and parking garages with solar panels.

The numbers are pretty significant, at least they were when the articles were published. Maybe they have come down enough to make it more realistic.

Nuclear lol
The last two nuclear units built in GA came at a cost of $36B for 2000MW or $18,000/KW

While the capital cost is high, the actual dispatch cost is low and why they are base loaded

What gives with the nuclear waste these days? How much is there and where do we put it? I love the idea of nuclear power but meltdowns and waste problems scare the shît out of me.

Great video all the way through, but go to the 7:45 mark in regards to your question

And seeing what landowners are being paid in rent it’s hard to see how this could be economically feasible. Might be time for you to retire & collect some big checks from the solar company.

There’s really not that much of it. And it’s pretty easily stored.

Im not sure when the credits expire but I’ve looked at financing a couple of these solar builds and long term economics don’t work without a fairly hefty subsidy. Not really gonna debate if we should offer subsidies for solar or not…. But I’m fairly certain there won’t be many people signing up to build a solar farm without the subsidies.

Problem with the short term lease to solar on farms is how the hell you reclaimed the land afterwards. If you're going to lease for "green" energy go with wind on farmland. Waaay less of a footprint. Also wind blows when it's cloudy and also at night.

Nuclear is constant for years upon years that's why our military has used it to power vessels for years. Too bad politicians haven't figured out how to make it popular and make money off it yet.
