This inspired me to finally read MIT's "Future of Solar" study, a substantial report on solar technology, economics, and trends.
As it happened, around that time the Breakthrough Institute ran an essay on one aspect of the MIT study. In the essay, Alex Trembath and Jesse Jenkins highlight the MIT theory that even though solar has boundless technical potential and very significant economic potential, it may be limited by its impacts on electricity markets.
Hence my new essay in Greentech Media, "Boom!: How Wind and Solar Will Blow Up Power Markets."
When you finish reading the essay, I recommend perusing the comments (currently over 200). Many GTM readers are experts themselves, and worth tracking.
