- Oracle founder Larry Ellison added a Tesla Supercharger station on his Hawaii island, per Bloomberg.
- Ellison has said in the past that he wants to make Lanai sustainable with electric cars.
- Some locals know he wants to make Lanai sustainable but are unclear on what his plans involve.
Billionaire Larry Ellison has put a Tesla Supercharger station on his private Hawaiian island in an effort to promote sustainability, Bloomberg reported on Thursday.
Ellison, founder of cloud-computing firm Oracle, spent $300 million on 90,000 acres of the Hawaiian island of Lanai in 2012. He owns 98% of Lanai's land, two Four Seasons resorts, and the majority of homes and commercial properties, per Bloomberg.
In an interview with CNBC in 2012, Ellison said he wanted to "turn Lanai into a model for sustainable enterprise," with plans to have electric vehicles on the island and convert sea water into fresh water.
As part of his sustainability mission in Lanai, Ellison has so far made room for one supercharging station designed to charge batteries in Tesla's electric vehicles, per Bloomberg.
The tech mogul has also opened a hydroponic farm on the island and has appointed experts to log rainfall, according to Bloomberg.
Bloomberg reported that some of the 30 Lanai residents it interviewed weren't convinced by Ellison's sustainability goals for the island because the billionaire hasn't gone into detail about what the plans involve.
Solomon Pili Kaho'ohalahala, a local who is on the advisory council for Hawaii's humpback whale marine sanctuary, told Bloomberg he has waited 10 years to talk to Ellison about conservation in Lanai.
Around 3,200 people live on Lanai, but many families who have lived there for generations have left, the report said.
On top of a Tesla Supercharger station now in Lanai, there are also Tesla solar panels which power the greenhouses owned by Ellison's agriculture-tech firm, Sensei Ag, Insider previously reported.
Ellison, who is on the Tesla board, is friends with fellow billionaire Elon Musk who has visited the island in the past and described it as "a microcosm for the world." The Oracle founder is the largest backer of Elon Musk's bid to take over Twitter.
Ellison did not immediately respond to Insider's request for comment.
