Kauai was 100% renewably powered for 32 hours over the last month
The Hawaiian island of 70,000 residents has achieved this feat on 11 different occasions since before Thanksgiving, anchored by a five-hour period on December 10. Plus, a world tour of high-penetration renewable hotspots.
Tesla to hide ‘solar test-house’ under tents at Fremont site
Lora Kolodny at CNBC uncovered a recently granted building permit that allows Tesla to put up “two canopy covers” over its new “solar test houses.” Earlier this year, Tesla CEO Elon Musk announced that 2019 was “the year of the solar roof.”
46% of U.S. homeowners want rooftop solar
A Pew Research Center survey shows that support for distributed generation and a desire for a residential installation of one’s own is up 6% nationally since 2016.
The quick gray fox jumped through the upside-down solar fence—a photo essay
Deer fence installed upside down lets foxes and other small wildlife through to forage and pursue prey. Solar developers in Tennessee and North Carolina have the photos to prove it.
MIT responds: batteries are critical to the future electric grid, but they have their limits
Recognizing their critical role in the future grid, MIT still sees limits to batteries in an intermittent renewable-dominated power sector. In this op-ed, John Reilly, co-director of the MIT Joint Program on the Science and Policy of Global Change, explains why.

MIT sees wind+solar going big, dreams of nuclear, forgets batteries exist
Researchers see wind and solar headed to over 40% of US electricity generation, even without major national policy. However, analysts project that beyond 40%, the intermittent nature of these sources will drive costs higher without nuclear power than with it.
Deeper analysis of bifacial solar panel data – including greater cooling and how DC to AC ratios affect clipping
Soltec single axis tracker research shows greater production in a two-in-portrait configuration versus a single module by just over 2%, driven mostly by lower module temperatures as well hardware design adjustments.
