No doubt a lot of electricity will come from fossil sources in the near future.  Your F150 can't refuel itself sitting in a sunny parking lot while you're at work, but an EV can sit under a solar panel awning and be juiced by when it's time to head home.  Or it can recharge from hydropower (note: your F150 cannot).

The grid of the (near) future will be driven as much by storage as by generation.  A parking lot full of 200 EVs represents a giant battery for grid stability and peak load matching and storing intermittent renewable energy.  Same goes for the fixed storage systems that are coming online.  Your utility will become a storage manager.  

In the US electricity usage over the last decade dropped by 2.5% even as our GDP rose by 10%.  Efficiency continues to be the best investment, and it's only accelerating.

The energy world is changing, my friend.  Not overnight, but definitely for your kids and grandkids.  What kind of economy do you want to pass on to them?
