Responding to shareholder pressure, Duke Energy is releasing today a climate-change report that sketches a drastically changed electricity mix in a carbon-constrained future.

Why it matters: As one of America’s largest utilities, its speculation on this front is a bellwether for how the country’s electricity mix may change in the decades ahead. Duke provides electricity to more than seven million customers in the Carolinas, the Midwest and Florida.

Gritty details: It outlines a 2050 scenario where the world has taken steps to cut greenhouse gas emissions to a level consistent with keeping global temperatures from rising two degrees Celsius. That’s the big ambition of the 2015 Paris climate deal, but the current commitments aren’t close to reaching that.

Duke’s 2017 → 2050 generation mix:

  • Coal: 34% → zero.
  • Renewables (wind, hydropower and solar): 1% → 23%.
  • Natural gas: stays at about one-third.
  • Nuclear: stays at about one-third. This relies on an assumption that federal regulators grant Duke additional operating licenses to allow their existing reactors to run 80 years. That’s never happened before, though several companies are seeking such approvals.
  • The report creates a new, vague category called “new load following, zero emitting” technologies, which accounts for 13% of its mix by 2050. This is a catch-all for low-carbon resources not widely available today, like carbon capture technology and advanced nuclear power.

One more thing: The report pushes back against a growing number of activists and companies calling for 100% renewable energy. Duke cites the lack of storage technology and the intermittency of solar and wind as reasons they can’t reach that level. For example:

“On our system, we’re seeing more peaking and high demand days in our winter months when solar output is very low and there is not currently technology to allow us to move solar output we may have on our sunny June day to January.”
— Cari Boyce, Duke's vice president of policy, sustainability and stakeholder strategy

Pope Francis was on Sunday visiting areas of northern Iraq once held by Islamic State militants.

Why it matters: This is the first-ever papal trip to Iraq. The purpose of Francis' four-day visit is largely intended to reassure the country's Christian minority, who were violently persecuted by ISIS, which controlled the region from 2014-2017.

Cuomo faces fresh misconduct allegations from former aides

The office of New York Gov. Andrew Cuomo (D) was on Saturday facing fresh accusations of misconduct against his staff, including further allegations of inappropriate behavior against two more women. His office denies the claims.

Driving the news: The Washington Post reported Cuomo allegedly embraced an aide when he led the U.S. Department of Housing and Urban Development and that two male staffers who worked for him in the governor's office accused him of routinely berating them "with explicit language."

Dozens of protesters were rallying outside the Minnesota governor's mansion in St Paul Saturday, urging justice for George Floyd ahead of former Minneapolis police officer Derek Chauvin's trial over the 46-year-old's death.

The big picture: Chauvin faces charges for second-degree murder and manslaughter over Floyd's death last May, which ignited massive nationwide and global protests against racism and for police reform. His trial is due to start this Monday, with jury selection procedures.
