Sure, PV solar panels lose 0.5% of capacity a year. Coal plants also require regular maintenance and replacement of bearings, boilers and turbines. Not to mention landfilling the ash produced by digging up rocks and burning them. Nobody has figured out a source of perpetual electricity that does not produce solid waste. If that happens, it would be real exciting. If China was the sole-source of steam turbines and enacted a export ban we would also be in trouble. But China isn't the sole source of coal plants, turbines, or PV solar panels.
