Far Fetched But Possible It Turns Out: Northern Lights Can Cut Your Winter Heating Bill

Geomagnetic storms, which cause northern lights, might
lower your fuel bill, believe it or not! 

 Since our brains might be still on celestial mode, given the wonderful eclipse we had this week, another event in the sky is making some science news.

Northern Lights.  None are in the immediate forecast, but hope springs eternal. 

In any event, this is a good excuse to lay out some new science that seems very strange, but quite possibly true:

The northern lights can lower your winter heating bill.

It's a convoluted, Rube Goldberg kind of process, but here goes, courtesy of an article in the Washington Post: 

The sun spews charged particles toward Earth, especially when there's a solar flare, basically an eruption on the sun. 

Those charged parcels bang into the extreme top of the atmosphere, where it excites molecules, which emit light. Those lights are the aurora borealis. 

Those particles eventually start falling toward Earth very slowly, and create molecules of nitric oxide and other chemicals. Once these fall into the stratosphere gradually over weeks and months. The stratosphere is where the ozone layer is, and those molecules can destroy ozone. 

If you destroy ozone in the stratosphere, it can cool that layer of the atmosphere. If scientists are correct, solar flares and the aurora can prevent something called a  "sudden stratospheric warming."

When that happens, it can disrupt the the polar vortex. The polar vortex, you might recall, is a swirling pool of intensely cold air in the atmosphere that lives in various places, usually in the Arctic during the winter.

If the polar vortex is tightly wound and near the North Pole, winter weather in places like the United States and Europe is usually relatively mild. 

If the polar vortex is disrupted buy a sudden stratospheric warming, it can stretch, weaken and move to weird areas. When that happens, it very often opens the door to Arctic blasts invading North America, Europe and/or Asia. 

Cold waves in the mid-latitudes increase electric and other utility bills. Which means if solar eruptions and the northern lights are more active than usual, it might keep money in your wallet.
