Elon Musk’s private jet appears to make frivolous flights, per Washington Post

Flight data obtained by The Washington Post shows that Tesla and SpaceX CEO Elon Musk has a private jet that logged about 150,000 miles in 2018. While many billionaires have private jets, Musk's jet stands out in the number of trips it made and miles it logged, the Post reports.

Perhaps most egregious, the plane logged a number of 20-mile trips, repositioning from the south side of Los Angeles to the north side. "Tesla said Musk never used the plane to fly between different spots in Los Angeles," the Post reports. Instead, the jet would make the 20-mile repositioning flights to meet the CEO at a closer airport.

Flying is an extremely carbon-intensive activity, made worse when only a few people are transported rather than many are on a commercial jet. According to the Post, the 150,000 miles that Musk's jet flew represents roughly 250 flights. Although it's not always clear that Musk was aboard every flight, the CEO's private jet made 100 more flights than the private jet of Jeff Bezos, CEO of Amazon (and owner of The Washington Post).

Coal will remain part of the US grid until 2050, federal energy projections say

On Thursday, the US Energy Information Administration (EIA) released its 2019 Annual Energy Outlook (AEO), which contains projections about trends in energy—from the amount of fossil fuels produced and sold, to the growth of renewable energy—out to 2050.

This year, against the backdrop of recent warnings from top scientists about the urgency of climate action, the EIA's projections don't look great. Coal, one of the most carbon-emitting sources of energy, is still projected to provide 17 percent of the United States' electricity in 2050, and that's assuming that no carbon-capture technology has been made mandatory. Natural gas—a fossil fuel that is less carbon-emitting than coal but still a problem for climate change—will increase its share of US electricity production from 34 percent to 39 percent.

These projections are from the EIA's "reference case," which omits any predictions about unplanned policy changes. But they do contain assumptions about how technology will change and the economy will grow. In the EIA's own words (PDF), "The AEO2019 Reference case represents EIA's best assessment of how US and world energy markets will operate through 2050, based on many key assumptions. For instance, the Reference-case projection assumes improvement in known energy production, delivery, and consumption technology trends."

"The US was already off track in meeting its Paris Agreement targets. The gap is even wider headed into 2019."

That's the dire news from Rhodium Group, a research firm that released preliminary estimates of US carbon emissions in 2018. Though the Trump administration said it would exit the Paris Agreement in 2017, the US is still bound by the agreement to submit progress reports until 2020. But the administration has justified regulatory rollbacks since then, claiming that regulation from the US government is unnecessary because emissions were trending downward anyway.

But it appears that emissions have increased 3.4 percent in 2018 across the US economy, the second-largest annual increase in 20 years, according to Rhodium Group's preliminary data. (2010, when the US started recovering from the recession, was the largest annual increase in the last two decades.)
