Reproduced from IEA, Future of Cooling report; Chart: Axios Visuals

The International Energy Agency forecast Tuesday that the number of air conditioners in buildings worldwide will more than triple by 2050, reaching 5.6 billion as demand surges in India, China and elsewhere.

Why it matters: Absent major efficiency gains, the added power demand will make it much harder to achieve the kind of worldwide carbon emissions cuts that would be needed to ward off potentially catastrophic warming levels.

The amount of energy needed for cooling will triple, reaching a level equal to China's total power demand, the new report finds. As the world warms in response to human-caused climate change, the need for air conditioning will become more acute, particularly in the Middle East and South Asia.

  • IEA estimates that left unchecked, air conditioning will account for 18 percent of the total worldwide increase in CO2 emissions by 2050.
  • And rising demand for cooling is "already putting enormous strain on electricity systems in many countries," IEA said.

The big picture: The report shows the immense challenge of increasing the health and well-being of billions of people, especially in increasingly hot places where air conditioning remains rare, while stemming emissions at the same time.

One level deeper: Air conditioning now accounts for about one-fifth of electricity used in buildings. IEA's "baseline" scenario, which models existing policies and targets, projects that by 2050 . . .

  • Cooling will account for 40 percent of the growth in power demand in buildings, and represents the second-biggest driver of all global electricity growth.
  • Even as the global power mix becomes less carbon-intensive as reliance on coal decreases, emissions from fossil-fueled generation associated with cooling need will double. That's in part because India — where cooling use soars — will still be using lots and lots of coal.
  • Cooling will account for 15 percent of all power-related carbon emissions.

What they recommend: The report lays out an "efficient cooling scenario" that greatly slows the amount of energy demand growth that accompanies expanded access to air conditioning.

It involves steps like stronger performance standards, better labeling, more global cooperation and greater use of incentives.

Under their scenario, power demand for cooling still grows over the next three decades, but by 2050 the energy needed is still half of what it would be under their "baseline" forecast.

“With rising incomes, air conditioner ownership will skyrocket, especially in the emerging world. While this will bring extra comfort and improve daily lives, it is essential that efficiency performance for ACs be prioritized. Standards for the bulk of these new ACs are much lower than where they should be."
— IEA Executive Director Fatih Birol

Rahm Emanuel floated for Transportation secretary

President-elect Biden is strongly considering Rahm Emanuel to run the Department of Transportation, weighing the former Chicago mayor’s experience on infrastructure spending against concerns from progressives over his policing record.

Why it matters: The DOT could effectively become the new Commerce Department, as infrastructure spending, smart cities construction and the rollout of drone-delivery programs take on increasing economic weight.

Biden turns to experienced hands for White House economic team

Joe Biden plans to announce Cecilia Rouse and Brian Deese as part of his economic team and Neera Tanden to head the Office of Management and Budget, sources tell Axios.

Why it matters: These are experienced hands. Unveiling a diverse group of advisers also may draw attention away from a selection of Deese to run the National Economic Council. Some progressives have criticized his work at BlackRock, the world's largest asset management firm.

Biden taps former Obama communications director for press secretary

Jen Psaki, who previously served as Obama's communications director, will serve as President-elect Joe Biden's press secretary, the transition team announced Sunday.

The big picture: All of the top aides in Biden's communication staff will be women, per the Washington Post, which first reported Psaki's appointment.
