Energy efficiency and getting off oil-fueled cars are two of the most effective ways California could meet its ambitious new clean energy law, according to a new report.

Expand chart
Data: Energy Futures Initiative; Chart: Chris Canipe

The big picture: California has America’s most aggressive climate change policies, including a recently passed mandate for 100% carbon-free electricity by 2045, and an executive order calling for 80% reduction in emissions across its entire economy by 2050.

Driving the news: The new report is led by President Obama's former Energy Secretary Ernest Moniz , who now runs a think tank called the Energy Futures Initiative. Its conclusions find that the more technological options California allows to meet its goals, the better.

Where it stands: This chart shows where the greatest emissions reductions can come from.

  • Energy efficiency, which is perhaps the least exciting type of technology, has the most potential, particularly for transportation.
  • Longer term energy storage — think seasonally — will be crucial, as will technology that can capture carbon dioxide emissions from polluting facilities.

Scammers seize on COVID confusion

Data: FTC; Chart: Sara Wise/Axios

Scamming has skyrocketed in the past year, and much of the increase is attributed to COVID-related scams, more recently around vaccines.

Why it matters: The pandemic has created a prime opportunity for scammers to target people who are already confused about the chaotic rollouts of things like stimulus payments, loans, contact tracing and vaccines. Data shows that older people who aren't digitally literate are the most vulnerable.

President Biden told congressional leadership in a letter Saturday that this week's airstrike against facilities in Syria linked to Iranian-backed militia groups was consistent with the U.S. right to self-defense.

Why it matters: Some Democrats, including Sens. Tim Kaine (D-Va.) and Chris Murphy (D-Conn.) and Rep. Ro Khanna (D-Calif.), have criticized the Biden administration for the strike and demanded a briefing.

The Food and Drug Administration on Saturday issued an emergency use authorization for Johnson & Johnson's one-shot coronavirus vaccine.

Why it matters: The authorization of a third coronavirus vaccine in the U.S. will help speed up the vaccine rollout across the country, especially since the J&J shot only requires one dose as opposed to Moderna and Pfizer-BioNTech's two-shot vaccines.
