The production from the electrical grid at a given moment is a small portion of total energy usage overall.
You also have to calculate how much initial fossil energy it took to create all the new 'fossil free' electrical grid components (turbines, solar cells, batteries, etc), how much fossil energy it took to deliver them all their locations (planes, trains, ships, semi-trucks, etc), how much petrol did the workers use to drive to where these items were installed, how much petrol and other fossil energy will be used to maintain them, etc, etc.
You think China didn't burn a ton of coal to MAKE those solar panels they're using in Germany or France or wherever you're talking about? You think plenty of diesel wasn't burned on ships and in semi-trucks to deliver to Germany? You think every home and factory in Germany is heated or powered with Electricity, not natural gas? And that there's no petrol-driven cars and diesel trucks there? You think the goods in the shops didn't arrive there on diesel-powered ships, and get transported to the shops in diesel-powered trucks? Think all the groceries in the grocery stores were produced with 'renewable energy', in all their sources, all over the world?
Fact is, nothing is actually 'renewable' in the way that people like to imagine that it is, quite frankly. There's ALWAYS fossil fuel-stocks involved all throughout the processes as they exist today.
And do you have any idea how much fossil fuel would be required to retro-fit all the worlds planes, trains, container ships, semi-trucks, harvesters, tractors, backhoes, and automobiles ... to all run on 'renewable' electricity? And THEN to produce the needed solar panels and wind turbines and batteries to POWER all of them? A freaking STAGGERING AMOUNT. And then when you consider their needed maintainance, battery replacement, etc?
It's not even REMOTELY proven this can be done ... in a way that doesn't turn out, in the end, to require MORE fossil energy.
No offense, but you're mistaken if you think anything of the sort is 'proven'.
