Why northern lights significantly reduce energy bills in winter. Northern lights have an impact on electricity consumption in the winter.
In the polar stratosphere, ozone depletion is accompanied by a cooling of the stratosphere and increases the swirling cold known as the polar vortex. A weaker polar-like vortex can bring lower Arctic storms to lower latitudes. Conversely, high geomagnetic activity strengthened the Arctic air at the pole, causing it to remain tightly wound to remain in the Arctic for a longer period of time.
