Here's a great video from Real Engineering [0] that goes into the pros and problems with that approach, and where and how it is currently being tried. For example, via undersea transmission cable under the Strait of Gibraltar. [0] [this video]

> why there's so much interest in nuclear when low-tech concentrated solar in the desert can get the job done and scaling it up (and ensuring it's 100% safe) isn't a matter of R&D but just basic manufacturing. Solar is dependent on the time of day (as the sister comments pointed out) and also on weather. Plus, you need to get the energy from the desert to wherever it's needed - this is non-trivial for densely populated areas far from the equator. You also need to maintain the solar panels; sand can be quite bad for their efficiency. Lastly, the areas that do have the space and solar power might be politically unstable, which makes the massive investments needed to get this going quite risky.

> we learned in geography class, that one could power the whole EU, if we occupied some area of the Sahara desert with solar panels I sometimes hear that too. The YouTube channel "Real Engineering" did a video about the idea: [1] The TLDR is: the Sahara definitely gets enough sun, but transmitting the power into Europe would be hard. [1]: [this video]

> Can we do the same in Europe and put massive solar panels in the desert of North Africa and import the energy northwards ? (I realize this is a super naive approach, and the main problem is energy storage rather than generation) A very good video from Real Engineering explains that no, not really: [this video]

Energy consumption is not an environmental problem (whatever you use said energy for, be it Bitcoin mining, heating your home or powering your massage chair), and all policies that try to limit energy consumption are basically building on quicksand and doomed to fail: the world has and will continue to consume increasing amounts of energy by capita. And anyone who's being an activist towards reducing energy consumption is completely deluded: energy consumption is strongly correlated with technical progress and civilization progress. Good luck putting an end to that short of reverting to the stone age. Energy production is what needs to be fixed, specifically energy production that results in

Interesting.. i thought it wasn't a good idea, based on this video (The Problem with Solar Energy in Africa, [this video] ) where is stated that Europe failed to do something similar connecting the North of Africa (Morocco and Algeria) to Europe (south of Spain).

> Speaking about solutions - until significant part of Sahara desert and the likes aren't covered by solar panels, i wouldn't believe that anybody (who matters) is taking the climate change seriously I think it is harder than we think, at least for the goals that Europe wants: [this video] The caveat about population control, is different than how we, humans, do with all other wild-life on planet earth, we cannot reduce the available food and habitat to lower the carrying capacity, compensate for the missing predators by killing individuals in the population, or slow the population's ability to reproduce.. We have to come up with a ethic solution. But people cannot put 3-5 kids or more on earth a

> I think it is harder than we think, at least for the goals that Europe wants: [this video] it seems that the main issue is that some invested in concentrated solar while photovoltaics energy cost fell from being 2x expensive to being 4x cheaper of the concentrated and just beating everything out at $0.03/KWh. As i said - cover the desert in solar panels. Transmission is only 7% loss to Berlin. Instead Europe is building gas pipelines from Russia and others. Again, money talk, and that clearly shows that nobody takes climate change seriously.
