After Musk Bitcoin U-turn, which coins are more climate friendly?

Bitcoin and Ether are the most environmentally unfriendly crypto tokens, but there are less-emissions-spewing digital coins out there.

Bitcoin’s lovers and haters have been fiercely disputing whether the number-one cryptocurrency by market capitalisation is good or bad for the environment. Bitcoin evangelists say that government-controlled fiat currencies and the whole financial infrastructure that backs them doom the climate. But Bitcoin critics counter that the process of mining new coins is a massive energy suck that benefits only a handful of people at a heavy cost to the planet. The naysayers just won over a powerful ally. After months of cheerleading for Bitcoin, Tesla CEO Elon Musk told his 54.3 million Twitter followers on Wednesday that the electric vehicle maker is hitting the brakes on allowing customers to use Bitcoin as payment.
