> It won't and it can't. Rather it can at the cost of ~20 trillion dollars (23GWh [1] at 900 million [0] for GWh for the Tesla battery). Sorry, this statement is incomplete and as a result, leads to an incorrect conclusion. Tesla (and other Li-ion batteries) are suitable for certain applications (e.g., powering cars, power tools, phones), but bulk energy storage is not one of them. Saying you want to store grid-scale power with tesla batteries is analogous to saying you want to replace the lights in a football stadium with thousands of mobile phone screens. You can do it, but screens are good at displaying image content to single users and not meant for general illumination, and would cost prohibitive from an acquisition standpoint not to mention the ancillary cost issues (e.g. lifetime, replacement). All you need to do is find an energy storage technology that is appropriate, and the solution suddenly becomes viable. Molten Salt storage, for example, is 33 times cheaper than Li-ion storage. Other much more appropruate mass energy storage options includes H2 production, or 'simply' pumping water upstream of a hydroelectric plant. 1. https://www.solarthermalworld.org/content/molten-salt-storage-33-times-cheaper-lithium-ion-batteries https://www.solarthermalworld.org/content/molten-salt-storag...
