You won't hear any complains from me about getting rid of the asinine "green" fuel ethanol. It's just an excuse to funnel farm subsidies to monsanto.
The issue replacing all of those fields is the interconnecting wiring and the limitations of inverters with shifting loads.
You remember trying to start a pump of any meaningful size on the boat while on the diesel resulted in the shitty 100 year old governor shutting it down? Kinda the same with solar panels. When a massive load shift occurs, the resulting transient can force anything with an inverter to trip, since they take voltage from the utility side usually.
Big spinning machines with a lot of momentum smooth out that spike with their rotational interia. The SSTGs and SSMGs were that big rotating hunk of metal for the boat.
