For wind sure, but is that true for solar? Solar panels are max 20% efficient and head pumps typically have a COP of 2-3, so solar thermal only has to have an efficiency of around 50%. 1 second googling tells me it is 70%.
I think the real reason nobody does solar thermal is because it's just so much less practical to deal with pipes and pumps and heat reservoirs than wires and batteries. Also it is useless in the summer when you don't need heating.
Wind is always going to be niche for most people for obvious reasons.
