A few years ago during the Enron/Calif. energy crisis, a paper mill in Washington State could not pay their electric bill so they brought in dozens of diesel generators. After a few days, the town people complained about the noise and smog
Ultimately, the paper mill closed for good (Georgia Pacific in Bellingham, WA)
I can only hope the same for the Beverly Hill Mansions!
