The report by the National Center for Public Policy Research, citing the public electric company that powers Gore's home, found that the 10,070-square-foot mansion used 230,889 kilowatt hours (kWh) of electricity during the past 12 months.
In September 2016, the home uses 30,993 kilowatt hours, as much energy as the typical American family uses in 34 months.
He said that Gore may portray himself a "religious prophet" for environmentalism, but he doesn't walk the walk.
Senior fellow at the conservative research center, Drew Johnson, chided Gore, an Academy Award victor for his 2007 global warming film "An Inconvenient Truth", for not facing his own "inconvenient reality".
Gore's electric bill was almost $22,000 from August 2016 to July 2017. He also owns two other homes not included in this report.
The group also wrote that despite allegedly spending "an estimated $60,000 to install 33 solar panels", the panels produce "only 5.7% of Gore's typical monthly energy consumption".
"Judging by his own home electricity consumption, Gore is failing to live up to the standards he expects of everyone else".
"Environmentalists should be the most furious", said senior fellow Drew Johnson, who authored the report.
Despite his tireless efforts to make the world a more environmentally friendly place, RadarOnline.com has learned that Al Gore devours a whopping 34 times more electricity per year than the average USA household. "It's just such hypocrisy, such Do as I say, not as I do".
But a lot of headache and a quarter million dollars later, the controversial politician still gobbles up a mammoth amount of energy and his huge rooftop solar array produces just 5.7 percent of the electricity he uses in his home! Johnson has been keeping tabs on this for years. "When I exposed those numbers, he sort of apologized and said he was going to change his ways and he spent about $300,000 doing green renovations to his house, [but] he still uses more energy today than he did ten years ago - and he claims to be the leader of the environmental movement".
