Tesla CEO Elon Musk surprised a lot of people last week when he tweeted that the electric car company would no longer accept Bitcoin (BTC) as payment, due to the environmental impact of cryptocurrency mining. 

It was surprising, in part, because Musk is seen as a crypto enthusiast and the firm just began accepting BTC in February, but also because Bitcoin’s massive energy demands are well established.
