sorry, but this is completely wrong for solar and wind power.. they are not steady a all... only if you add a battery storage system you could have a 24/7 steady power supply...
and this is exactly the reason why it is pretty problematic to power BTC mining by solar or wind...
better not bring this up as argument why BTC should be sustainable
