If building them becomes difficult because of missing materials, the prices would rise, which is not happening at the moment.
Solar panels have indeed become cheaper and cheaper, and you are right to argue that the materials used to build solar panels are priced in. However, solar requires some infrastructure besides the panels themselves, such as inverters and storage, and that infrastructure needs additional materials, some of which are expensive. Copper, for instance, surged in price in 2020, and there is not enough investment to expand mining operations despite the great profits it has been yielding. This is an ongoing saga in the mining industry, with BHP attempting to take over Anglo American in part for its copper portfolio.
I am not arguing against solar; I just think it cannot be scaled to the extent necessary to cover most of our current and projected future electricity consumption. To get rid of fossil fuels and generate ever more electricity for EVs, the AI black hole and goddamn cryptocurrencies, I think we will need nuclear. I wish we would build more public transportation, break from the AI spell and ban cryptocurrencies, but I’m not hopeful. In any case, the pace solar has picked up these past years is very encouraging and we should do what we can to push it further.
To my knowledge, Zelenskyy only expressed support for Israel after October the 7th, 2023, over a year and a half after Russia launched its full scale invasion of Ukraine — a year and a half during which Hamas, Islamic Jihad and the Palestinian Authority could have condemned Russia’s war against Ukraine. They didn’t, presumably, for the same reason Zelenskyy has expressed support for Israel: to avoid antagonizing their allies, morals be damned. Given their dire situation –both Ukraine and the Palestinians rely heavily on their respective allies for military and diplomatic support–, I think we ought to give them a pass. If you disagree, at least apply the same logic to both and condemn them equally.
