Must still be private....dk...
Absolutely right......energy storage has to accompany solar for real broad base use....
What seems to be the case is that the best applications would be large complimentary power plants that will produce for less $ than other options....
Everything enters by price...."in the daytime".....
Electricity is continuous with peak trough daily demand....
Solar augments daytime demand....
ie cheaper than coal during peak daytime demand .....seems to be possibly economical....
The goal...."just lower cost" clean (non fossil) (renewable) price lead energy"....wherever it is....could also be country dependent....some countries where electricity is far more expensive than in the developing countries, etc....
ie solar in day.....capacitors (the new storer) replacing batteries at night ? ie for the price of a hotwater heater ?
Bottom line.....the system has to be clean,renewable, 24/7, price led....
