> And as promising as renewables are, they still cannot [...] modulate their output to comply with variances in grid demand Even if you forget to count hydroelectric as a renewable (my country has a huge amount of hydroelectric, and every time I look at the realtime power generation graph, it's the hydroelectric that's following the load, while thermal generation is flat), other renewables like solar and wind can also reduce their output as necessary to match the load. They currently don't because, since they're the cheapest power source, it makes more sense to reduce the generation elsewhere first.
