The average windspeed at the San Jose Int'l Airport is 9.5 mph, coming from the south/southwest, except in December and January when it comes from the northwest. This is not enough to justify largescale turbines, but smaller building-mounted products could potentially harness these slower wind speeds, providing power at the household or block scale.

The sun hits its highest point in the sky, 78 degrees above the horizon, at noon on June 21. The lowest noontime point is at 30 degrees on December 21. Between April and August, the sun rises and sets above the E-W line. This means that there are times at the edges of the day when direct light can enter north-facing windows (this is important mostly for the hot late afternoons in the middle of the summer).
