Building Dashboard

About a year ago Caltech installed a 200 kW solar array on top of one of the parking structures, its the largest solar installation in the city of pasadena. Recently I saw that they had a "building dashboard" showing how much power they produced.

On sunny days in winter they're producing about 514 kWhs per day, which is roughly how much I used for an entire AC heavy month.

The part that's scary, is they'll cover that KWH to other units, like dollars of electricity, or pounds of coal, or... gallons of gas.

That 514 kWh could have been generated from just under 15 gallons of gas.

It boggles the mind how much energy we use going to and fro.
