Workers install solar panels on homes in Corona, California. Photo: Will Lester/Inland Valley Daily Bulletin via Getty Images

Earlier this month, the California Energy Commission mandated that all newly constructed low-rise residential buildings must include solar power

Why it matters: While California prides itself on its leadership on climate change and innovative energy technology adoption, this decision is likely to misfire. Forcing people to install solar panels may actually exacerbate grid problems, creating negative secondary impacts without meaningfully greening the electricity system.

Most experts agree that the electricity grid will become more decentralized, with generation coming increasingly from customer-sited equipment. But even Elon Musk, a vocal proponent of solar roofs, believes that ultimately the grid will still get two-thirds of its supply from large, central generating plants, in part because electricity is much cheaper to produce at scale. Rooftop solar, given its cost disadvantages and small market share, is not the most cost-effective avenue to greening our electricity supply. 

In fact, in California, there is a mounting problem of too much solar during the sunniest parts of the day, which cannot then meet the system's demands when the sun goes down, barring expensive storage solutions. This means that the value of solar energy produced by these panels will actually decline as more are installed. 

Some experts also warn that the mandate will increase housing costs at a time when prices are beyond the reach of many lower-income people. It would be cheaper for homeowners, and more cost-effective overall, to focus on solutions to current problems, including well-placed storage that addresses the challenge of after-dusk solar supply.

The bottom line: The California Energy Commission has made a mistake. It makes sense to require new homes to be energy efficient and solar-ready, but California's climate goals would have been better served in this case by more informed regulation.

Food delivery "ghost kitchens" face major obstacles

The growing popularity of food delivery has given rise to startups that open "ghost kitchens" — kitchens in warehouses or trailers that prepare food solely for delivery and have no option to dine in.

  • But they can come with a whole host of problems.

The big picture: The concept of "ghost kitchens" has been dubbed the next big thing in the future of services, with high profile backers like Uber founder Travis Kalanick. But these kitchens can be hard to run or unsafe.

CNN announced Tuesday evening that it has suspended anchor Chris Cuomo indefinitely following new revelations about his involvement in the management of his brother's sexual harassment scandal.

Driving the news: New documents released Monday showed that Cuomo used his contacts to garner information about the women accusing his brother, former New York Gov. Andrew Cuomo, of sexual harassment, as well as of emerging media coverage relating to the scandal.
