"I already have all the power I need every day."   This is a choice you made and I congratulate you for it.  But reality is it is an outlier.  Most people either cannot or will not follow suit.  Most of us want to buy electricity from the grid, and in fact, some of us have gone to the trouble to install a natural gas powered generator (egad) for those instances where a transformer blows down the street or weather leaves us without power for a little while.  Pollution or not.  
 
 Generated at my home without any moving parts or pollution." I think that's great, every little bit helps, and I'm sure there is a sense of self-satisfaction about it.  While there will be more homes so-equipped over time, the reality is that is not the solution. 
  Utility scale and storage is where it is at.  Not individual homes.  It simply doesn't rank high enough on the average person's list to get the attention required to go the extra mile as you have.  We do like our conveniences in the US.  
  I credit Musk with having the broad knowledge and awareness and special skills it took to accomplish what he has.  We product, for transportation, a couple billion metric tons a year of carbon emissions, which regardless of how one feels about it, cannot be a good thing.  
  Emission savings are tiny so far 15MMT/year, but at scale it will matter.  Not only that, other Musk innovations like Utility-Scale battery systems are saving around that amount as well.  In the overall scheme of things 30MMT is not a lot, the trajectory is certainly 
  Progress is being made and will ramp up in due course.  
  Now I don't know if you believe CO2 is a huge problem at this point, like some. (I don't).  However, I like clean air just on general principle.  I remember driving onto I635 during drive-time in the mornings (years ago) and seeing the crud in the air on the horizon toward the west side of Dallas.  Some days it made me gag just looking at it. 
  I don't want that crap in the air and to date, Elon Musk has done more toward eliminating the problem than any person on the planet.  IMO.  But there are ups and downs and there surely will be.
