I wonder how practical it would be to build a system that would let home appliances cheaply overuse energy when there is a peak in wind or solar production. For example: * Let heat-pumps heat homes to say 23C instead of 20C * Let freezers decrease the temperature to say -30C instead of -18C * Let electric water heaters heat water to say 70C instead of 50C, such water can then be mixed with more cold water Such overus…
You'll have enthusiasts that'll do homebrew systems to take advantage of the economy, then you'll have companies catering to their (tbh, hobby), then you'll have products that are actually useful, then you'll see mass adoption. Like in everything else.
Trying to plan a huge strategy from the onset feels (and is!) daunting. Just make sure the price fits the reality, and savings will follow naturally.
