Of course those publications are completely factual and unbiased...
The fact is that "probable cause" articulated in a sworn affidavit before a judge is required to get a search warrant. High power consumption alone is insufficient to establish probable cause. I'm thinking there are some pertinent facts being excluded from the stories you have read.
One of the people who's home was raided back in 2004 lived one town over from me. The electric company alerted the police to the families "excessive" usage. So they observed the home and on garbage day they saw the owner taking the trash to the curb just as the garbage truck was pulling up wand found that behavior "suspicious". Then they brought in a drug sniffing dog. The dog apparently reacted "positive" when walked "near" the home. A warrant was issued and the police broke into the home which had no small effect on the mother at home and her two small children. What did they find? Simply a household that had been using a large amount of electricity and absolutely on sign of any illegal activity whatsoever. Those were all the pertinent facts shown to the judge.
