Renewable Energy Connection

My daughter asked me a funny question yesterday: "Do you think it was sunny enough today that I could have a smoothie?"
Funny but practical.  You see I bought a powerful blender at Walmart, so powerful that its power demands overload the PV system, so unless the sun is blazing down, I usually have to start up the generator for the minute or so that she needs the blender to make her smoothie.
And I'm glad that: 1. she has a gut sense of the connection between energy production and energy demand without boring lectures and powerpoint demonstrations, and 2. that she is making a smoothie because they're yummy.
