Storage is nowhere near enough if we want self sustainable green energy. And author should compare winter moths when it comes to solar panels production - worst case. Yes, there is development and each day a breaking new battery tech is announced but until these get produced for real in mass quantities, they are vaporware. Mind that we need storage for like at least a week, better a month of energy worth. And that’s a lot of batteries.
Do you have any data how much of those batteries are in fact in use? For example, Slovenia needs something north of 1.5 * 24 GWh energy for a day. And we are 2 mills population. Plus during winter you need to charge them. With short days of like 5 hours of less than ideal sun if no clouds or fog … good luck. Perhaps eventually we’ll get there, but it’s really far far away.
