Claim: Keeping cool in the summer leads to increased air pollution

The war on air conditioning continues.

A new study “reports” that hot weather leads to more air conditioning use which requires more electricity generation which leads to more power plant emissions which leads to more “air pollution.”

While greater electricity generation necessarily leads to incremental increases in power plant emissions, those emissions cause no harm to health or the environment.

In contrast, air conditioning use is necessary for our health, safety and productivity.

Also, “energy efficient” buildings are more costly and circulate unpleasant stale air.

Keeping cool in the summer leads to increased air pollution

As the weather warms, so does the use of air conditioners. But running these devices requires power plants to ratchet up electricity production, causing air polluting emissions to rise. An analysis of 27 states found that, on average, summer emissions of sulfur dioxide (SO2), nitrogen oxides (NOx) and carbon dioxide (CO2) go up by hundreds to thousands of metric tons per degree Celsius increase. The report appears in the ACS journal Environmental Science & Technology.

A large body of research has investigated the influence of weather and climate on atmospheric chemistry. But few studies have examined the specific effects of climate on electricity emissions and air quality. Although overall emissions have dropped due to pollution control devices and a drop in coal use, regional and seasonal increases in power plant pollution could affect people’s health and the environment. SO2 and NOx — both of which are regulated in the U.S. — can cause respiratory problems, particularly in children, people with asthma and the elderly. CO2 is a primary greenhouse gas targeted by power plant regulations. Tracey Holloway, David Abel and colleagues wanted to quantify the historical relationship between summertime air temperature and the power plant emissions of these three gases.

Using data collected between 2003 and 2014, the researchers crunched the numbers on electricity emissions in 27 states, mostly in the Eastern U.S. From this analysis, they observed that power plants released 3.35 percent more SO2 on average per degree Celsius increase in temperature, and NOx and CO2 rose by 3.60 percent and 3.32 percent, respectively. States with more coal power plants such as Ohio, Pennsylvania and Indiana released the most electricity-related SO2 emissions in the summer at more than 1,300 metric tons per day, per state. However, New Jersey, Connecticut and Vermont power plants released very little SO2. States like Texas with a large power demand showed high emissions of all pollutants, but smaller changes in emissions per degree Celsius. Overall, the calculations showed that hotter outdoor temperatures correlated with 140,000 metric tons more CO2 emissions. The researchers say that making buildings more energy efficient, especially on hot days, could play an important role in lowering power-plant emissions and improving air quality in the future.

  1. We could also recycle a 10,000 old idea, and all move into caves. Another idea would be to stop worrying about silly things.

  2. I are a intellectual,
    12 years o climate studies see.
    I learnt o global warmin’
    From Al Gore and IPCC.
    I learnt the sun don’t warm the earth,
    Ain’t causin’ us to fry,
    Hit’s jest a big fluorescent bulb
    A liten’ up the sky.
    Hit’s only mann made CO2 that’s causin us to roast.
    Of all the people I despise,
    I hates them skeptics most!
    So stop a usin’ fossil fuels!
    Your lifestyle redesign!
    Please notice I said “yours”!
    Don’t even think o changin’ mine!

  3. Okay. Power companies have to maintain a max level power production to cover peak periods of use. Remember rolling brownouts? Energy efficient buildings may help with SO2 increases during those peak periods of use, but realty is that, during severe episodes, power companies will generate more power and more SO2. AC and heating aren’t the culprits. Also, energy efficiency goes up, but fees and charges do not go down. Wait for it! …higher taxes are next!
