But it does not answer the question. The question would be: Where does the baseline have to be? Yes, they have lots of fossil fuels, but you could still replace that with reneawables as long as you have enough electricity left at night when there is no wind. Additionally, it could matter whether you and your geographical neighbours share a power grid and support each other, etc…
but you could still replace that with reneawables as long as you have enough electricity left at night when there is no wind.
That would require storing all that energy, which isn’t feasible right now and realistically not anytime soon unless we get some kind of battery breakthrough (Still waiting on those solid-state and graphene batteries)
I wonder why we haven’t been looking into mechanical flywheels more ofr the energy storage. They’re far less energy dense sure but their service life blow batteries out of the water long term and when you’re building static grid scale storage space isn’t really a concern.
We have those, that’s pretty much how big energy plants work (Coal, gas and fusion all use that I think), it’s not exactly a flywheel, but a large turbine which can keep spinning for some time. I think a full on flywheel would have to be absolutely massive to produce enough energy to be meaningful, which is probably just not worth it
And Georgia doesn’t have that? (serious question, I’m from Germany)
I’m from Portugal, but a web search found this https://www.georgiapower.com/company/about-us/facts-and-financials.html which shows 63% of the grid there is fossil fuels.
