The 4 GWe wind farms have an average capacity factor of 35% so over ten days that's 336 GWh or 4.8 million Teslas, and that's just for the fraction of electric generation that's wind in the PNW. Scale that up to full electricity and then full energy and you're looking at a pretty serious challenge. Batteries are generally not what people consider for grid-scale power. The 100% renewable Stanford superstar, Jacobsen (who's suing his scientific critics), doesn't even use batteries in his scenarios (he uses pumped hydro and hydrogen instead).
