It’s cold. Damn cold, at least here in San Francisco (although the weather maps show a lot of blue and purple shading in the rest of the country as well!). My apartment, while costing the equivalent of sending two kids to college for a year amongst the four of us, has neither heat nor window insulation. That means it’s super cold inside as well! Getting up in the morning is definitely tough…
To fix this, we have some space heaters, but that’s not enough, and not the best for the environment. One problem is that the windows are single-pane, another is that the windows are pretty loose in the frame.

Hopefully this will help- it has certainly made a difference in my room. And remember: the way PG&E calculates your bill, anything above the ‘normal’ range can really add up.
