Only natural gas doesn't need storage you idiot. Every other fuel source needs to be stored before it is burnt.Really? How is needing storage for energy when it can be reliably produced on demand not stupid? Explain why using, variously, flywheels, batteries, pumped hydro, or whatever to store energy is a desirable thing that will lower electrical energy costs compared to production on demand.
Shut the fuck up you blazing retard.
