Battery storage suck. We don't even have decent electric cars. Why should power companies buy expensive wasteful batteries?
batteries lol....you know what a transformer is right?
Yes, it converts (transforms) alternating current to either higher voltage with lower current or lower voltage with higher current. It does this through electrical induction between two coils with differing numbers of windings. What does that have to do with the discussion at hand?
They only talk batteries when they talk solar cells/wind energies. Stuff that produces electricity when it's not necessary.
The current grid doesn't need batteries with its current design.
A voltage is potential energy. A transformer transforms voltage yes but is also a storage of potential energy via a magnetic field.
So, yes you need a battery for wind energy or solar energy because it does not produce a steady state energy. Thus you can't power a transformer because you do not have a constant potential difference. You think a coal power company or anything that runs off a turbine is using batteries lol?
