The energy consumed by mining — the process that keeps Bitcoin’s blockchain running — has been an increasingly popular topic of discussion in recent weeks.

On Friday, CNBC posted an interview with SUKU CEO Yonathan Lapchik, during which he explained the Bitcoin mining scene as it relates to renewable energy. The interviewer noted Lapchik previously claimed that 75% of Bitcoin mining comes from renewable energy.

“We think that 75% is an actual figure,” Lapchik told CNBC, “The miners are truly incentivized to use renewable energy." Turning his thoughts to electric car-maker Tesla, which recently announced it would no longer accept Bitcoin for purchases due to environmental concerns, Lapchik said “It’s surprising that Elon didn’t consider that before getting into the space, before accepting Bitcoin as a payment mechanism for Tesla.”

Tesla opened its doors to payments via Bitcoin by United States clientele back in March. The move went public following the car company’s purchase of $1.5 billion worth of BTC, announced in February.

Musk, however, recently stated disapproval of the fossil fuel energy Bitcoin mining calls on, via a Tweet on Wednesday. He also discontinued payments to Tesla in BTC, albeit seemingly a temporary move until Bitcoin mining reaches satisfactory energy usage levels.

“Really the data has been there forever,” Lapchik said of the 75% number. “We’ve been proving over and over and over that that’s a real case for miners in the Bitcoin network.”
