Cold Crunch is Coming. ACs are stretched to Limits; Need to Transition to More Efficient Electricity Grid Using Solar & Wind Before More Climate Change.

SITUATION :
Air conditioners are contributing to Rolling Blackouts & Use of Solar & Wind.
There is a serious lack of electric power generation on the grid.
Electricity grid lost 4000 MWs of generation by nuclear & coal decommissioning.
The Grid starting to cause a search for a magical solution by some.
Basic technology operates much as it did when introduced nearly a century ago.

SIGNIFICANCE:
Rolling blackouts caused by record-breaking heat waves baked Californians last month.
Collective strain of air conditioners forced grid operators to cut off power.
Air conditioning represents one of most difficult technological problems to fix.
Air conditioners produce enough heat to measurably boost urban temperatures.
Units produce highly potent greenhouse gases & will push up electricity demand.
AC units need to become far more energy efficient to avoid “cold crunch.”

Why it matters:
It’s a small hint of what’s likely to come in California and far beyond.
Growing populations, rising incomes, increasing urbanization, & climbing summer temperatures
could triple the number of AC units installed worldwide by 2050,

SOLUTIONS:

AC units has become more efficient but projected usage is large;
Global electricity demand will still soar in the future.
Need to build larger systems than ever & do it all with carbon-free sources.
Need to overbuild electricity systems to meet levels of demand every year.
The most crucial fix needs to occur outside the AC industry.
Transitioning electricity grid as a whole means greater use of clean energy.
Use of solar & wind will steadily reduces indirect greenhouse-gas emissions generated by air-conditioning units.
Developing smart grids could help electricity systems deal with the peaked demand.

What’s needed:
Demand for cooler air in commercial & residential building putting strains on A/C Capacity
Basic A/C technology operates much as it did when it was introduced .
Startups & research groups creating cleaner & more efficient cooling technology.
The most crucial fix needs to occur outside the AC industry.

SAYS:

“The fact that window AC use continues to increase while the product largely looks and works the same as it has for decades speaks for itself,” “I think a lot of folks are excited for something new here, but there has only been incremental progress.” – —  Vince Romanin, chief executive of San Francisco–based Treau,

STATS:
Pushing the total toward 6 billion.

Alternative refrigerants could reduce emissions by the equivalent of around 50 billion tons of carbon dioxide in the coming decades, according to the high-end estimate from a Project Drawdown analysis. (The world emitted nearly 37 billion tons total last year, according to the Global Carbon Project

AC energy demand would still leap about 70% higher by midcentury.
