Today’s homes are all heated as a requirement of the Universal Building Code. While air conditioning isn’t a regulatory requirement, heating is. The heating must be adequate to maintain the home in the “comfort zone” even in the most-extreme temperatures for that part of the country. There’s only one problem, though: Nearly all home heating systems depend upon electricity to function. When the grid goes down, that expensive hardware doesn’t do us the least bit of good.
Unfortunately, the power grid is the most vulnerable part of our infrastructure. Every severe weather event causes the grid to go down, albeit temporarily. Cyber-attacks have already been committed, showing that the grid can be taken down artificially. Almost anything can cause a power outage.
