Tesla CEO Elon Musk tweeted Sunday that the company will begin taking bitcoin (BTC, +4.43% ) as payment if the cryptocurrency’s power-hungry miners turn halfway green.
Musk called a halt to Tesla’s months-long cryptocurrency experiment in mid-May, citing environmental concerns. Tesla would begin permitting Bitcoin transactions “when there is confirmation of appropriate (50 percent ) clean energy consumption by miners with a favorable future trend,” he wrote in the tweet.
Musk hasn’t said how he’ll fact-check miners’ renewable energy consumption because there’s a lot of disagreement about where the sector is right now. Nonetheless, the remarks serve as a starting point for Tesla’s reintroduction of bitcoin payments. Musk’s tweet also reaffirms his justification of selling 10% of the electric car maker’s bitcoin holdings in Q1, implying that the business hasn’t sold any more.
