Mega mansions cost their owners between $10,000 and $50,000 in electric bills, reports say.
A record-breaking $141 million mansion known as "the costliest house sold at auction," has monthly electric bills estimated at around $50,000.
California's San Diego Gas & Electric raised its rates due to higher supply costs, and the new bills cost residents nearly 12% more than last year on average, the Wall Street Journal reported.
Castillo said those hoping to cut down on electricity bills should focus more on their A/C units instead of turning off lights and appliances.
In the LA Times report, he said that makes up 70% of electric bills during the summer.
