I was involved with solar in the UAE and sand was a major problem because the panels become ever so slightly damp with condensation in the morning and coated with a fine layer that had to be washed off.

[@Charlesscul]

A quick search shows that Chile's natural energy reserves are massively underdeveloped. Along with the deserts where cloudy days simply don't exist, you have all that coast line along some of the world's stormiest seas, which is perfect for offshore windfarms. Also, it looks like you have a huge amount of geothermal energy that is untapped.

One of the issues he didn't address is the problems with the falloff of the efficacy of photovoltaics outside of +/- 30 degrees latitude from the equator caused by the increasingly indirect nature of sunlight in those areas. Atacama may be too far south and in sunlight that is too indirect to be as cost-effective as it needs to be there. It may be OK as a supplemental source, though. I need to look into what Germany is doing, as they should be having some issues with this. The USA will learn this the hard way over the next few decades too... I worry it will hurt the reputation of Solar overall, which is not a bad technology. It just has limited use and is not the panacea those looking to solve the Climate/Energy issues hope it to be. Honestly, we need to get solar panels into space where they are unobstructed and transmit the power back to ground stations on Earth via microwave, but that's probably about another 50 years off.

The video is titled "The Problem with Solar Energy in Africa", but after you watch the video, you realize there isn't much of a problem after all. When he bitches about US$150 million to connect Morocco with Spain, I was almost completely sure whoever wrote this video works for Shell or Texaco. Hell - we lose much more money if a Saudi billionaire is on a bad mood and decides to either increase or decrease oil production. I'm sorry to the people behind this video - I really do appreciate your effort to promote science. But I've just had enough of all this talk about the cost of solar power. We don't have to dig 5km down the planet's crust to get solar power. We don't have to build marine-life-extinguishing tankers to move solar power around. Concentrated solar was a bad idea to begin with, and one that could only come from the minds of fossil fuel addicts who are unable to grasp the simplicity and cleanliness of photovoltaic. Your sponsor seems like an ally on the fight for a better world. Unfortunately, your video does look like a knee-jerk appeal to Big Oil's sensitivities. Also... what's the deal about the tone when speaking about the potential political problems within North Africa's countries? What year is this - 1910? It's still OK to talk like an imperialistic dipshit in 2021? I've written too much already. Bitching about this is as useless as trying to make regular people understand why oil is killing us all.

Where I thought the video would go was to discussion of the reduced infrastructure and electrification within not just Morocco but across Africa. After all the sensible thing for electrical generation and transmission absent knowing anything else about the regions would be for plants in the Sahara to power Morocco itself and the countries nearby, transmitting across land, not across ocean, which is terribly inefficient. One might imagine that building power plants in Morocco and transmitting the electricity, for example, to Mali, south, might make some sense. But there are grid problems, security and infrastructure problems, and there are also poverty problems. Mali is one of the 25 poorest countries in the world per capita. Only half the population has access to electricity. So if a profit-driven corporation examined the idea of transmitting from Morocco to Mali, it would not only ask what the electricity challenges are. It would ask: "Who exactly is going to pay us?" Until that sort of problem is resolved socially, the fanciest and largest plants in the world won't make sense.

It should be noted that centralized power generation will always be a terror target. That is not unique to northern Africa. Not only terror attacks, but also weather events. Decentralization increases robustness of the system, though it brings with it concerns of complexity and increased costs. Even so, I believe decentralized power generation will become the norm in the medium to distant future. In a way, when considered from a wider perspective the US power grid is already decentralized. Each plant being interconnected with other plants reduces outage time and frequency. Imagine if it became economical to decentralize to the extent that if your neighbor's power generation went out, the rest of the neighborhood could power the house until repairs could be made.
