@tictacdude3468 It's not really resistivity. AC suffers from capacitance between the cable and its surrounding (air, ground, water). This is extremely true with undersea power lines and one of the reason we barely do underground lines as well. Those days we only use AC because of historical reasons and the technological inertia it created. Going full DC will require a lot of changes, both in the power distribution network and the electrical appliances compatibility (which could need some dedicated lines with a local inverter inside the electric box)

@ianhamilton3113 The wind turbines installation production is minuscule compared to gas or nuclear plants though. And wind doesn't allow full production capabilities during the peak hours or weeks whereas gas or nuclear reactors can be turned on at will in a short time.

@beyondfossil problem is not every renewable energy production is that renewable. And dismantling Big Oil is honorable but not in the expend of making ecologically disastrous photovoltaic panels coming from a single country (PRC) keeping tense relationships with our countries. Though wind farm also needs prospecting, construction and transport using fossil fuel.

but like in my country, Taiwanese are too much concerned by nuclear power to effectively ditch fossil fuel.

@flexairz I know, I said "concerned" because they are unreasonably afraid of it.

We can't decently call photovoltaic cells as green energy. Those use a lot of energy and quite rare materials to be manufactured. Although it's very questionable to think photovoltaic is the cheapest when maintenance is still high and production is really low compared to other power sources.

@johndoh5182 rofl take your pills kid and stop acting stupid. I don't understand why you're focusing about oil and gas but that wasn't what I compared photovoltaic to. Nowhere near that because what you replied is common knowledge. Nuclear plants are way more green than photovoltaic kid, and they produce way way more power than your entire country covered by solar panels, especially the crappy ones sold nowadays. Or if you want to still go solar, the good old CSP plant tech doesn't require disposable e-wastes panels the size of a football field as well as being more efficient and needing less maintenance. Though the power usage curve can be seriously flattened by taking measures to prevent excessive consumption but you know, consumerism and industrial lobbies are strong. Finally, dry locations doesn't prevent dust deposits AT ALL. Just look how the Martian wind was a crucial factor for the different solar powered rover missions from NASA.

@billysgeo Sure but prices decreases a lot these days. Although HV transformers are way way less efficient than HVDC multi stage switch boost converters and the lesser heat is more spread and easier to cool. This efficiency difference is already true without counting on better semiconductors than our good old doped silicium so it could only improve whereas AC stations are difficult to improve without an internal DC conversion. All of this is meant to reduce losses on the grid to reduce plants and as it goes the costs seems to be there for those new designs to come out even for nonsubmerged HV lines.

constantly cleaning the panels and the environmental cost of producing them is quite a large downside for photovoltaic though.

Well, seems Dimitri deleted his comment.
