Royal Dutch Shell has agreed to acquire a 44% stake in Nashville-based solar energy company Silicon Ranch.

Why it matters: This is part of Shell’s expanding alternative energy portfolio, although it remains a very small part of the oil-and-gas giant’s overall business.

In October, Shell bought NewMotion, a major European electric vehicle charging company, and late last year said it would boost spending on its alternative energies division from $1 billion to $2 billion per year until 2020.

More broadly, several European oil majors are increasing their alternative energy investments. For instance, last month BP ventured back into solar energy with the announcement that it’s investing $200 million over three years to gain a 43 percent stake in Lightsource, a major European solar power developer.

CDC to cut guidance on quarantine period for coronavirus exposure

The CDC will soon shorten its guidance for quarantine periods following exposure to COVID-19, AP reported Tuesday and Axios can confirm.

Why it matters: Quarantine helps prevent the spread of the coronavirus, which can occur before a person knows they're sick or if they're infected without feeling any symptoms. The current recommended period to stay home if exposed to the virus is 14 days. The CDC plans to amend this to 10 days or seven with a negative test, an official told Axios.

  • The CDC did not immediately respond to a request for comment.

Health-care workers and nursing home residents should be at the front of the line to get coronavirus vaccines in the United States once they’re cleared and available for public use, an independent CDC panel recommended in a 13-1 emergency vote on Tuesday, per CNBC.

Why it matters: Recent developments in COVID-19 vaccines have accelerated the timeline for distribution as vaccines developed by Pfizer and Moderna undergo the federal approval process. States are preparing to begin distributing as soon as two weeks from now.

Obama: Broad slogans like "defund the police" lose people

Snapchat.

Former President Barack Obama told Peter Hamby on the Snapchat original political show "Good Luck America" that "snappy" slogans such as "defund the police" can alienate people, making the statements less effective than intended.

What he's saying: "You lost a big audience the minute you say it, which makes it a lot less likely that you're actually going to get the changes you want done," Obama told Hamby in an interview that will air Wednesday morning at 6 a.m. EST on Snapchat.
