Solar Works Wherever People Live
Um...um...um...
It is a bourgeois conceit - and regrettably it is prevalent on our end of the political spectrum - that so called "renewable energy" is a viable solution to poverty on this planet, poverty being something about which very few of us actually know anything at all and about which we care even less.
Here's a clue: The overwhelming majority of people who live in bamboo and grass huts are not looking for a solar cell to power their video games. In fact, the main effect that solar cells is likely to have in the third world will be to raise the serum levels of toxic metals in children of all ages when this stuff turns into electronic waste - which it will before most middle aged bourgeois people die - and is sent to third world countries to be "recycled" so everyone in rich countries can feel all "green."
Solar energy is useless in the first world, and if anything it is worse than useless in the third world, given, as is the case with everything else, the lives of third world human beings are considered expendable in order to provide for the smug complacency associated with citizens of the first world. The third world is where the most toxic materials for "green" renewable energy is mostly mined, and it will be the place where most of it will end up being dumped.
It's disgusting.
One of the largest health risks in the third world, besides air pollution for which the solar industry has just racked up half a century of doing nothing to address - is the lack of adequate sanitation.
Some notes from the World Health Organization's "fact sheet" associated with this issue:
68% of the worlds population (5.0 billion people) used at least a basic sanitation service.
2.3 billion people still do not have basic sanitation facilities such as toilets or latrines.
Of these, 892 million still defecate in the open, for example in street gutters, behind bushes or into open bodies of water.
At least 10% of the worlds population is thought to consume food irrigated by wastewater.
Poor sanitation is linked to transmission of diseases such as cholera, diarrhoea, dysentery, hepatitis A, typhoid and polio.
Inadequate sanitation is estimated to cause 280 000 diarrhoeal deaths annually and is a major factor in several neglected tropical diseases, including intestinal worms, schistosomiasis, and trachoma. Poor sanitation also contributes to malnutrition.
WHO Fact Sheet: Sanitation
We may all feel smug about this not being our problem, although I can tell you my septic system failed a few years back and I got a new appreciation of this issue, even though I'd been considering it sometime.
A paper published in the current issue of Environmental Science and Technology suggests that even if it's not the same level of problem as it is for people living in grass huts powered by swell solar cells, maybe cadmium telluride babies, it's not entirely trivial for first world bourgeois types.
The paper is here:
Application of SourceTracker for Accurate Identification of Fecal Pollution in Recreational Freshwater: A Double-Blinded Study (Sadowsky et al, Environ. Sci. Technol., 2018, 52 (7), pp 42074217)
From the introductory text:
The authors note that the most modern methods, based on qPCR technology, for determining the source of fecal matter has demonstrated ambiguities which they seek to resolve using machine learning type algorithms.
The goal is to distinguish fecal sources from horse, cows, cats, dogs and wastewater treatment plants (WWTP). The study was double blinded to determine the accuracy of their methods.
I don't have much time this evening, and won't go through the paper in any detail, but will show some pictures from the paper along with captions, and then offer some text from the conclusion:

An "OTU" is an "Operational Taxonomic Unit."
Some concluding remarks:
If you're curious about actual sources of actual shit, you may click on the link to the paper, which is probably not open sourced, and then find the "SI" supplemental information PDF link and open it. This should be open sourced, and you can learn whence shit in recreational waters comes.
You know, we're surely not perfect on the left, and it is not enough to say we're not as bat shit mad as the people on the right, including the orange baboon in the White House. It is not enough to be "not as bad as..."
The challenge is to be good; to be decent, and decency involves, well, to go with the theme here, "giving a shit."
We should care as much about the people in the third world who are described in the WHO fact sheet, as we do about how bad walking our dogs on the beach is for water skiiers.
Just saying...
We can be so clueless:
Solar cells on grass huts...you see this kind of thing, but you really don't want to believe it.
Have a nice "hump day" tomorrow.
