From Wired Magazine's Blog: New Plant Could Drop Cost of Solar Power to 1.5x US Average
The comments interested me more than the actual posting.
Key Points from the comments:
1. Most electricity from solar is generated not by photovoltiacs, but by solar/thermal.
2. Efficiency for Solar?Thermal is around 60%. Photovoltiacs in the lab is 40%, and 18% with what's in production.
3. An Arizona house uses twice as much electricity as one in Denmark. My guess on reasons is size of house and air conditioning.
