You are describing the impact of anything not rooted in defensible truth. Nonsense has been the blight of the modern world since the dawn or critical thought. That’s ~2500 years of struggle between thinking and following.

Edit: Writing appears 3500-3000 BCE, but the first writings about reasoning/critical thought don't appear until ~500 BCE. There is no actual evidence of conflict between reasoning and believing prior to then, and that's a long period of writing without a single mention. Before the early Greek thinkers, there doesn't appear to have been much. Knowledge was scarce and reason even more so. And after the decline of Classical civilization, it was almost completely lost to the 'West' for centuries until the Greek texts were rediscovered by the Arabs. Had they not done so, many might have been lost forever.

I was curious (and didn't have a prior), but the answer appears to be yes. I found the largest man-made reservoirs on Wikipedia: the largest 100 manmade reservoirs in the US have about 8500 sq mi of surface area. Assuming 15% efficiency you'd need something like 20,000 square miles of solar installation to power the US based on this Dept of Energy document: Link.

More interestingly, the largest 25 reservoirs in the US have just under 5000 sq mi of surface area.

Many of these reservoirs are in places that don't receive full sun of course. But I think people underestimate just how large some bodies of water are. An area the size of, say, Lake Erie would be sufficient to provide solar power for almost all of the US with full sun - less than 1% of land area in the contiguous US. The federal government owns about 40 times that much land already, much of it in places that are ideal for solar.

The COVID-19 pandemic was fertile ground for conspiracy theories and misinformation on Twitter, and Bill Gates was a frequent target. A new study, which analyzes well-known conspiracy theories about the role of Bill Gates during the pandemic is published in Cyberpsychology, Behavior, and Social Networking.

K. Hazel Kwon, Ph.D., from the Walter Cronkite School of Journalism and Mass Communication, Arizona State University, and co-authors analyzed 313,088 tweets surrounding Bill Gates over a nine-month period in 2020.

The investigators define conspiracy theories as "explanatory narratives about the ultimate causes of significant social and political events, with claims of secret plots by powerful actors."

The findings showed that each conspiracy theory is not an isolated event; instead, they are highly dynamic and interwoven. "Most conspiracy theories that emerged in our dataset were complementary to one another," stated the investigators. "Such findings allude that individuals' beliefs in one conspiracy theory may reinforce another, which leads to more sharing behaviors in digital space."

Utility scale solar (putting all the panels in one place) has enormous advantages over distributed solar (putting panels in random places all over). With the costs averaged out, energy from distributed panels can easily be 10x more than solar energy that comes from utility scale locations. Higher energy prices are regressive, meaning they hurt the poor more than they hurt the rich, and imo should not be encouraged when a cheaper option exists that is environmentally similar.

Also research the duck curve. Until we solve storage, there are certain places that shouldn’t have more solar installed.
