Yes, the current ways of doing intensive farming are hard on the land and ultimately very wasteful. If you look at the progress in pesticide free organic farming and indoor/vertical farming, what they have in common is that they leverage a more data driven approach where you simply don't need to pre-emptively correct problems if you can manage the environment in which you grow plants better. Avoiding the conditions that cause pests and weeds to get out control is much more efficient than dealing with them after things get out of control.
Basically, intensive agriculture is compensating for its destructive nature by just brutally suppressing any "undesirable" growth. In nature, pests target the weaker plants. Basically, you stress out plants by mismanaging them and they are fair game for a wide range of fungi, insects, etc. E.g. under or over watering them, depleting the soil, etc. all stress plants out. If you have unhealthy soil, it's hard to have healthy plants growing in it.
Intensive agriculture starts with disrupting the soil (by plowing it). This causes the soil to degrade over time and releases captured carbon into the atmosphere. The natural response is for aggressive weeds to start growing in disrupted soil. To "fix" this, farmers use a mix of pesticides and fertilizers. The pesticides kill a lot more than just the pests and weeds and then further degrades the soil and the bio diversity in and on it. And finally the fertilizer is just bleeding out of the land straight into the ground water and surrounding areas. It works but it is resource intensive. You need lots of water, chemicals, energy, etc to grow a single crop at the cost of literally anything else. Basically modern intensive farming grows mono cultures on top of artificially created deserts.
Organic farming avoids doing that. Try not to disrupt the soil. Kill off (and compost) weaker plants rather than trying to rescue them. Use nature to keep pests and weeds in check. Etc. It works but it is more labor intensive. You need people to look after things. You get healthier and tastier produce (cooks love organically grown stuff for this reason). However, automating that labor makes it more scalable. That's the opportunity here.

By what measure is vertical farming more efficient?.
I've heard the contrary regarding green house gas emissions, it is still less efficient in most crops, it consumes too much power and that overcompensates any efficiency gained in other areas
It's interesting that this conclusion can change drastically if electricity becomes 10-100x more efficient
I don't know what you've heard and where you've heard it but there is generally a lot of misinformation floating around and most of it is being sponsored by lobbies with an agenda to keep the oil and gas companies going. So, I would suggest not taking any of that at face value. Including what you hear in threads like this or from me.
Vertical farms are essentially closed systems where nutrients, energy and some water goes in and produce comes out. There's a bit more to it of course but that's the general idea. They are climate controlled environments where light is provided via grow lights. In short, it uses energy which needs to come from somewhere.
You are confusing power requirements and greenhouse gases. Mostly these things use some form of sustainable power. Either sourced indirectly via some electricity provider; or directly with e.g. solar panels. If you think about it, the number one expensive consumable here is electricity and the cheapest way to produce it is via renewables. It's that simple. Why would you get more expensive energy if you can get it cheaper. Keeping all those ACs, lights, pumps, etc. going you are going to have to figure that one out or deal with competition that is smarter than you on that front.
There are probably a few farms that are forced to buy via the grid and are hopelessly dependent on their local coal burning monopolists. Not a great business plan but the good news is that coal is rapidly becoming a very unfashionable way to produce power due to the fact that it is expensive and dirty. It being expensive cuts down on energy margins and causes coal dependent producers to be dealing with awkward things like going bankrupt and being forced to pay more for their coal than they can charge for the resulting energy when wind is blowing and the sun is shining. Gas has similar issues, as people that pay gas bills these days can vouch for. Mine went up by 2x recently. Not great.

Solar's efficiency is below 50% [https://www.nrel.gov/pv/cell-efficiency.html]. Considering that, I'd guess for each m² of solar panel deployed, you'll get <50% of the yield that would be produced in that same land with horizontal farming (assuming fertile land).
You can argue that solar panels can be deployed in non-agricultural surfaces, and that's true, that allows to grow things where it was not possible before. But I'm not convinced that vertical farming is more efficient than horizontal on very important metrics like cost and GHG emissions
