try to do some math
work out the KWH of a electric car doing just 20miles a day(normal use)
multiply that by how many cars need to be electric soon
then realise that cars would require MORE electric than bitcoin mining industry
Fun fact:
World's electricity consumption in 2019: 23,900 TWh = 23,900,000,000 KWh
Estimated number of cars in 2019: 1.4 billion = 1,400,000,000
If we assume (exaggerate) that each car will have a battery of 40KWh and will have 200km autonomy and driving just 20km per day (12.5 miles) that means they would need
56,000 TWh EVERY 10 DAYS ! So
2,016,000 TWh per year. That's over 84X the current TOTAL electric consumption JUST from cars alone.
BTC consumes an estimated
127 TWh per year.
We've got 99 problems but crypto mining ain't one !
Keeping in mind the most important factor, without gold and silver, all electronic equipment wouldn't exist
They can just develop some new alloy materials to replace them. Expensive to R&D but probably cheaper in the long run !
