This installation will include almost 200,000 square feet of photovoltaic arrays
on top of Google's buildings as well as parking lot shade structures (a greatdual-use that generates electricity as well as shading the cars parked in thesun all day so they need less air conditioning and thus use less fuel).
Whether this was prompted by the recent passage of pro-solar power legislation in California or not, it will be one of the largest corporate solarinstallations, and is expected to result in almost $400,000 in annual energy costs at today's rates and is expected to pay for itself within 7.5 years.

You better think for a sec, before posting comments 
When I get into my car, that's been standing in the sun, I max the aircon for quite some time

The cars will need less air conditioning because they'll take less time to cool ONCE you turn them on. (i.e., if you get into a car and it's extremely hot outside and the car is sweltering, it takes more AC to cool the car than if you get in the car and it's relatively cool already. A modest savings for sure, but a real one.

I lived in Houston for a long time. If no one knows, it gets hot there. There is always concern about finding shade to park in. Any help to cut down running time for cars can help. The whole point to solar power is to help clean the air. I know what I say next will be mean and bitchy. Was GTW talking out of his ass? Or was he stoned? Google, of all people, need every square foot they can get.

to the best of my knowledge, car air conditioners have a duty cycle. When it's on, there is a constant load on the engine, regardless of varying the temperature control (which is basically just a bypass valve, controlling the mix of a/c coldish air with ambient to produce the desired output temp). so...."need less air conditioning" would imply that it would be turned off when a desired set temp was reached, which most people just don't do.

The entry almost looks like the poster did an automatic find on "shade" and replaced it with "requires less air conditioning and thus use less fuel". Statements like these just make no sense and it just makes it harder for people to take the subject seriously.
