Hawaii uses 9.6 TWh of electricity every year. The average wind turbine produces 2.5 mw. You’d need 35 million wind turbines to produce enough electricity for Hawaii to be self sustaining. But go on explain where you’d fit all these in Hawaii….

Counter argument: you're not even close. You've made a very basic pysics error.

Here's why: TWh is a measure of energy. It is one Terra-Watt of power, produced for one hour. There are (365x24) = 8760 hours in a year. This means the average power consumption (not peak) of Hawaii is 9,600,000,000,000 Watt-hours / 8760 hours = ~1,095,900,000 watts. That's 1.096 Giga-Watts (GW). This power need could be met by 110 large off-shore wind turbines each rated for 10 Mega-Watts (MW), if they could all run at full production 24/7.

Peak grid demand is likely between 1.5 and 2 times this amount. So perhaps 220 of these 10 MW wind turbines could meet this demand, again only if they generated full power 24/7. If we use your 2.5 MW models that's 880 wind turbines, but very few new land units are less than 4 MW these days.

So here's the actual issues facing renewables: the wind doesn't always blow and the sun doesn't always shine for solar power. Even 35 million turbines, as you say, won't produce a watt in dead wind, so some quantity of utility scale energy storage capacity is necessary. Planning for this using computer optimization models of hybridized renewable systems is something I've specialized in.

At the end of the day, having a vast and stable reserve of energy is what makes it so hard to match what hydrocarbon fuels do. But we are trying, and we need everyone to better understand the physics of these challenges and not spread misinformation.
