Good question. I am unclear about heaters but I do think some of them are out for some team members and you may be right on that. Ovens also are commonly gas but ones since 1990 require an electric light. But... stovetops which are gas do not require electronic ignition. The risk is of course carbon monoxide poisoning; hopefully you have such detectors as part of your in-home fire detectors. The problem is not so much the deliberate rotating blackouts who can get restored after a time, but large groups of people for whom power is out due to some other weather-related outage issue; there are large swaths of them in Houston at least according to the Centerpoint Energy outage map which distinguishes between the two (but does seem to be not the most timely updated data per various people I have talked to whose status has changed during today: http://gis.centerpointenergy.com/outagetracker/ http://gis.centerpointenergy.com/outagetracker/ )
