Only to a point, if all you have is solar for example, then any demand after sunset isn't going to help, no matter how much you attempt to manipulate demand.
As it is, solar helps with businesses during the day, though you still have to manage the difference between peak output and cloudy days, plus wind that might work best on the coast at around sunset and sunrise. We do need more renewable energy sources that are always-on, wave for example (the moon disappears or we stop rotating, we've got bigger problems). The trouble is that it is way more expensive than wind or solar which is probably why its not been implemented in any large scale system.
