Four states now generate at least 30% of their electricity annually from wind, now that Oklahoma and Kansas have joined Iowa and South Dakota on the 2017 list. That's one factoid from the American Wind Energy Association's annual report on the state of the wind power market.

Why it matters: It's a data point that underscores the growth of renewables in U.S. power markets. The chart above shows the penetration of utility-scale wind nationwide.

By the numbers:

  • Overall, wind supplied a record 6.3% of U.S. power last year.
  • The U.S. was home to 13% of the new wind power capacity added globally last year, and is a distant second to China in overall capacity and generation.
  • Total U.S. wind power capacity additions last year were slightly over 7,000 megawatts, which is roughly 9% growth.

This is one of the bigger signs of trouble for President Trump that we've seen in a poll: Of the final debate's seven topics, Joe Biden won or tied on all seven when viewers in a massive Axios-SurveyMonkey sample were asked who they trusted more to handle the issue.

Why it matters: In a time of unprecedented colliding crises for the nation, the polling considered Biden to be vastly more competent.

Entomologists in Washington state on Thursday discovered the first Asian giant hornet nest in the U.S.

Why it matters: You may know this insect species by its nom de guerre: "the murder hornet." While the threat they pose to humans has been overstated, the invading hornets could decimate local honeybee populations if they establish themselves.
