LONDON: Earlier this month, Elon Musk offered US$100 million to fund a competition to find new ways of removing carbon dioxide from the air or water.
To win a slice of the cash on offer, competitors have “to create and demonstrate a solution that can pull carbon dioxide directly from the atmosphere or oceans and lock it away permanently in an environmentally benign way”.
The move helped burnish Musk’s green credentials, doubtless appealing to all those buyers of his Tesla electric cars who pride themselves on doing their bit for the environment.
Yet before swallowing this green image, both they and Tesla’s shareholders might be wise to take a closer look at how the company is actually spending their cash.
ENTER THE BITCOIN CONUNDRUM
Last week, Tesla disclosed it had invested US$1.5 billion of its reserves in bitcoin and unveiled plans to accept payments in the cryptocurrency for its electric cars, albeit “initially on a limited basis”.
Cue much cheering from bitcoin mavens and another lurch upward in its value to more than US$48,000 — up two thirds so far this year.

For bitcoin isn’t environmentally neutral — it’s carbon-tastic idiocy. And the cheerleading of Musk actually makes it worse.
SERIOUS ENVIRONMENTAL CONSEQUENCES
Critics deride bitcoin as useless, saying it lacks income and utility. Yet this punter’s plaything has serious environmental consequences.

“Mining” bitcoin — the process by which the supply of coins is augmented — requires electricity on a vast scale to run the computers involved.
According to the Dutch economist, Alex de Vries, it chomps through around 78 terawatt hours (TWh) a year globally — equivalent to the consumption of Chile, a country of 20 million.
Each bitcoin transaction uses the same amount of power as 436,000 through the Visa payment system.
Nor is this especially clean power. As de Vries points out, bitcoin miners are not interested in intermittent renewable energy.
