That's off by several orders of magnitude. Wikipedia says ~4100 TWh/year, Wolfram Alpha ~3900 TWh/year. It's also 35 GWh of battery production, not 35 GW (which seems obvious in retrospect but I just spent 10 minutes trying to wrap my head around how the 35 GW figure could fit in). A 1 GW power plant -- which incidentally is quite large -- generates (if run at capacity) 365 * 24 = 8760 GWh per year.
So, not 3.5%, but roughly 0.001%.

- DVassallo 13y agoI grew up in a small country of 400K people, which in 2012 generated 2.2GWh of power. [1] This is very easy to calculate, since the country has only 2 power plants, and the electricity grid is completely isolated. [2] I was astonished to realize that the battery output of 4 weeks from the gigafactory would power my native country entirely from batteries for a full year!
