Tesla Solar Sales Declined for 4 Qtrs. Then Tesla Stopped Publishing the Numbers (cleantechnica.com)
I have to put my hands up — when Tesla acquired SolarCity in 2016, I supported the decision. Yes, Elon Musk was chairman of both companies. Yes, it was his cousins who were CEO and CTO, and had founded the company based on a suggestion from Elon Musk at Burning Man. Yes, Tesla was saving SolarCity financially in key ways.

Deregulated energy markets accelerate solar adoption (seanobannon.substack.com)
Solar power has become the cheapest source of new electricity generation in many parts of the U.S., but adoption depends heavily on market structure. Deregulated markets, where entrepreneurs and independent power producers can directly pursue profitable opportunities, have rapidly embraced solar, while regulated utilities remain slow to change due to legacy investments and bureaucratic oversight. To accelerate the shift to renewables and a cost competitive future, the U.S. should pursue greater deregulation, enabling private capital to build a cleaner, larger-capacity grid.
