Plunging costs make solar, wind and battery storage cheaper than coal
Maybe I'm missing it, but I don't see an indication of how much storage they are talking about here. The problem with renewables is still intermittence, and geographic dependence. Solar does no good at night, and there are days the wind doesn't blow. The costs of storage for that bulk application still don't seem to make sense, and I don't see it addressed here. The Tesla battery replaced power on the order of seconds, which is still a success, but not enough.<p>In general, solar has been great for reducing peak demand, since it has highest output during the middle of the day when electricity demand is also greatest. Not clear how much farther it can go, though. Wind may be able to replace some, but wind isn't strong everywhere.
