Obama has not put forth any policy that tells us we can't refrigerate our food or heat our homes, you're speculating on things that have not even happened yet. The United States still has a healthy grid system, I can personally vouch for this because one Christmas a couple years ago my family stayed in a cabin visiting some relatives. This was in the most remote corner of Georgia and South Carolina you can think of. The area barely has internet, it does still have electricity, we did not freeze, we did not starve.
