There is that, and also getting consumers to understand.

For instance, every time I do an energy audit around my house, I recognize I
have lower hanging fruit by utilizing negawatts.  I still have incandescent
light everywhere.  I have one bulb that is inside a grandfather clock, 40
watts, burns 24/7.  I have wanted that off for a long time, but my wife
loves it.  That one bulb burns about a kWh per day.  At local insolation, it
would require about a 250 peak watt module to run just that.  A 250 is about
a meter by about 2 meters.  Those 250s are in the region of 400 bucks.  All
that could be cancelled by turning off one single light bulb.

I have enough south facing roof for about 1.5 kWp with no heroics or

I need to look into that.
