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

Arizona GOP's private recount of 2020 election confirms Biden's win

In an odd coda to the 2020 election, private contractors conducting a GOP-commissioned recount in Arizona confirmed President Biden’s win in Maricopa County.

Why it matters: The unofficial, party-driven recount has been heavily covered on cable news as part of former President Trump's continued effort to sow doubt about the election result.

The last migrants camping under the Del Rio International Bridge, which connects Texas and Mexico, departed on Friday, Homeland Security Secretary Alejandro Mayorkas announced during a White House press briefing.

Driving the news: Thousands of migrants, mostly from Haiti, had arrived to the makeshift camp after crossing the southern border seeking asylum. Roughly 1,800 migrants will now head to U.S. Customs and Border Protection processing centers.

The White House said in new guidance Friday that it expects millions of federal contractors to be vaccinated against the coronavirus no later than Dec. 8.

Why it matters: Companies with federal contractors have been waiting for formal guidance from the White House before requiring those employees to get vaccinated, according to Reuters.
