We fact-checked Donald Trump’s latest comments on renewable energy.

According to a new report from the International Energy Agency (IEA), renewable energy, mostly solar and wind, accounted for more than half of all new electric capacity added in the world last year, a 15 percent jump from 2014. Globally, there is now more renewable power capacity than coal power capacity.

Clean energy growth was especially high in China, which was responsible for about 40 percent of all new clean energy capacity. Get this: In China in 2015, two wind turbines were installed every hour.

This surge in renewables, according to the IEA, can be attributed to policy changes, lowered costs, and improvements in technology.

So renewable energy hit some big milestones last year, but it’s still just the beginning: The IEA — which has been accused of underestimating the growth of renewables — expects 28 percent of electricity to come from renewables by 2021, up from 23 percent today.

“I am pleased to see that last year was one of records for renewables and that our projections for growth over the next five years are more optimistic,” said IEA Executive Director Fatih Birol. “However, even these higher expectations remain modest compared with the huge untapped potential of renewables.”

So let’s keep this moving, folks.

White Teachers Think Pretty Poorly of Their Black Students

Bob Somerby draws my attention to a new study about the effect of race on teacher evaluations of students. The authors took advantage of a large dataset that included evaluations of students from two teachers each. They then compared the teacher evaluations of each student based on differences in the teachers’ races.

The chart on the right tells the story. White students didn’t suffer from having a teacher of another race. Expectations of dropping out were the same and expectations of getting a college degree were actually higher. Hispanic students were modestly affected. Teachers of other races thought Hispanic students had a slightly higher chance of dropping out and the same chance of completing college.

But black students were enormously affected. Compared to black teachers, teachers of other races thought their black students had a far higher chance of dropping out and a far lower chance of completing college. Since the baseline expectation of dropping out was 31 percent for black students, a change of 12 percentage points represents a whopping 39 percent increase. Likewise, the baseline expectation of a college degree was 37 percent for black students, so a change of 9 percentage points represents 24 percent decrease.

The authors conclude with this:

The general finding of systematic biases in teachers’ expectations for student attainment indicates that the topic of teacher expectations is ripe for future research. Particularly policy relevant areas for future inquiry include how teachers form expectations, what types of interventions can eliminate biases from teacher expectations, and how teacher expectations affect the long-run student outcomes of ultimate import. To the extent that teacher expectations affect student outcomes, the results presented in the current study provide additional support for the hiring of a more diverse and representative teaching force, as nonwhite teachers are underrepresented in U.S. public schools.

Let’s ask all our presidential candidate what, if anything, they think we should do about this.
