I’ve always wondered about all the huge mining operations that would be necessary to get the materials to manufacture hundreds of millions of huge batteries. Never mind the storage systems needed for storing electricity for the home. Caterpillar is probably drooling over the potential.
Of course we need to develop this technology, but God forbid we force a technology that is nowhere near ready and end up doing real damage to the planet.
It’s bad enough having our natural landscape mutilated and blighted by industrial wind turbines.
