It missed us by 9 days

I'd argue for a correction to replace "more infrastructure" with "better infrastructure" - smaller less interconnected grids IMO are a better path forward in the future.  Higher resilience due to less centralized generation and vulnerable/expensive distribution, and less opportunity to dump the "waste heat" into our atmosphere (as of this writing, about 1/3 of all energy produced goes out a cooling tower).
  
Think about it - during a hemisphere's summer months when sun is plentiful, PV and solar heat can meet the needs of a given building.  During a hemisphere's winter months when the sun is less available, a combined heat and power system can burn natural gas locally (starting with digester gas from sewage treatment and landfill reclamation) and you get the benefit of a heat output from an electricity generation source to heat the building while converting a more harmful form of greenhouse gas (CH4) into a less harmful type (CO2).  Extra electricity can be used to drive a heat pump for additional heat rather than storing in another form - because you should be using a dual-mode heat pump anyway (air conditioners we are all familiar with are single mode).  Naysayers will claim solar thermal heat doesn't work well, but that's probably just down to poor system design - in North America, it works even in Canada and Alaska when done right: https://www.youtube.com/watch?v=eJMOM01NA40
  
Abundance and "out-of-sight-out-of-mind" generation results in waste.  If you had to generate your own power and it was harder to do so than flipping a switch and paying a few cents an hour - you wouldn't waste so much of it, and the less energy one uses, the less waste heat there is as well.  Less usage will lead to lower total CO2 output, but nobody really wants to talk about lifestyle changes.
