Leaky power grids that waste energy before it reaches consumers are an often overlooked source of carbon emissions, per The Conversation.

What they did: Researchers calculated the pollution from additional energy needed to make up for what's lost in transmission and distribution systems worldwide.

  • The experts with Johns Hopkins and the University of Maryland tallied "compensatory emissions" based on generation sources and grid quality in different countries.

What they found: It's big when you add it all up.

  • The losses also vary a lot by country, notes the piece derived from a recent paper in the journal Nature Climate Change.
  • "In 2016, aggregate transmission and distribution losses reached 19% in India and 16% in Brazil," they note.
  • They were over 50% in Haiti, Iraq, and the Republic of Congo, which "means that only half of the electricity generated reached or was billed to the consumers as usable power."

What's next: They call for greater attention to stemming emissions through use of better tech and infrastructure upgrades.

  • Various ways to lower energy loss include replacing inefficient transmission wires, using superconductors to reduce resistance in transmission wires, and configuring distribution lines in a better way.

Biden's doctrine: Erase Trump, re-embrace the world

Foreign policy will look drastically different if Joe Biden defeats President Trump in November, advisers tell Axios — starting with a Day One announcement that the U.S. is re-entering the Paris Climate Agreement and new global coordination of the coronavirus response.

The big picture: If Trump's presidency started the "America First" era of withdrawal from global alliances, Biden's team says his presidency would be the opposite: a re-engagement with the world and an effort to rebuild those alliances — fast.

Robert Mueller speaks out on Roger Stone commutation

Former special counsel Robert Mueller responded to claims from President Trump and his allies that Roger Stone was a "victim" in the Justice Department's investigation into Russian interference in the 2016 election, writing in a Washington Post op-ed published Saturday: "He remains a convicted felon, and rightly so."

Why it matters: The rare public comments by Mueller come on the heels of President Trump's move to commute the sentence of his longtime associate, who was sentenced in February to 40 months in prison for crimes stemming from the Russia investigation. The controversial decision brought an abrupt end to the possibility of Stone spending time behind bars.
