Just to keep things real and your eye on the ball, there's a caveat (well, several) to the statistic you've quoted and linked.
That's "close to" 50% renewables in some regions toward replacing current electricity generation.
If all vehicles stopped using petrol | diesal tomorrow and automagically becam electric the demand for electricity would increase dramatically and renewable contributions as a percentage would dwindle.
It's good work so far but there's still a long way to go, much to do, and a few billion tonnes of mining to churn through just to provide resources for your goal.
