President Trump is again trying to make good on his campaign promise to revive coal — this time by ordering Energy Secretary Rick Perry to “prepare immediate steps” to support economically struggling “fuel-secure” nuclear and coal plants.

Why it matters: The subsidies required for this bailout proposal would only mask the true underlying problem: Coal has simply lost out to other technologies and fuel sources.

The big picture: Subsidies have a place and purpose — namely, to help nascent technologies achieve economies of scale. But it's economically and environmentally irresponsible to subsidize 135-year-old technology that can no longer compete against newer, more efficient options. Cheap natural gas and, to a lesser extent, renewables have reduced wholesale market prices to the point where coal can no longer make money in many locations.

Be smart: In a way, we already subsidize greenhouse gas emissions by not putting a price on the damage they cause. If the Trump administration wanted to save nuclear power without directly intervening in the markets, one option would be to remove environmental pollution subsidies by putting a price on carbon. Because nuclear power has some of the lowest carbon emissions of any energy source, a price on carbon would let nuclear plants, especially existing ones, compete in a more equitable market that acknowledges fossil fuel emissions' harmful effects. (It could also represent a bipartisan compromise.)

The bottom line: There are reasonable measures the government can take to support struggling energy industries — and in the case of nuclear power, removing pollution subsidies could be an arguably justified intervention. However, only abject market manipulation and more subsides can stem the economic forces that are killing coal.

Mary Trump book: How she leaked Trump financials to NYT

Simon & Schuster

In her new memoir, President Trump's niece reveals how she leaked hordes of confidential Trump family financial documents to the New York Times in an effort to expose her uncle, whom she portrays as a dangerous sociopath.

Why it matters: Trump was furious when he found out recently that Mary Trump, a trained psychologist, would be publishing a tell-all memoir. And Trump's younger brother, Robert, tried and failed to block the publication of "Too Much and Never Enough: How My Family Created the World's Most Dangerous Man."

Brazilian President Jair Bolsonaro announced Tuesday that he tested positive for coronavirus.

Why it matters: Brazil's coronavirus outbreak is one of the largest in the world, topped only by the U.S., and Bolsonaro has long downplayed the effects of the virus, pushing businesses to reopen over the last few months in order to jumpstart the country's economy.
