I know I sound sarcastic but Tony Seba might find a solution by the year 2030: how to store energy to cover the needs of a city like New York(a city that never sleeps). He has been right on the spot regarding his previous predictions, right?
And everyone who has studied electrical engineering for real, knows that you are always going to need base stations running on fossil fuel or nuclear energy because solar/wind power is unpredictable.
The ones who benefit out of this is the companies you do the huge installations and then increase the prices on utility bills because "practically+scientifically" alternative powers sources are not cost efficient.
Especially the wind power is useless, if you don't have base stations running on coal/nuclear energy to cover for energy variations.
But in the end, the serfs buy it thinking the climate will be saved while the corporations just get richer.
