A quick dump of links on solar power recently:
1) This article riffs on an Our World in Data article showing the falling price of solar. Watch out- you might get hit!
2) The full set of benefits associated with solar power are enumerated in this article based on this research (behind paywall) include the fact that solar is most productive during times when the grid is under the most stress, i.e. when air conditioning requires a lot of electricity. Also they say that having solar on the grid helps make sure that the grid itself is better maintained.
3) Finally, not about solar but about the alternative: the Guardian (lefty-alert!) writes that fossil fuels were associated with over 8 million deaths in 2018, mostly due to air pollution, and mostly in East Asia, including India and China. The former was dramatized in a NY Times piece in December.
