PowerWall doesn't remotely scale to grid-scale, and 150MW battery deployments don't begin to address the hundreds of 2000+ MW coal plants [1] out there. They're a band-aid that only works in specific use cases. Battery manufacture, recycling and transport, combined with the need to replace most of the cells every decade are seen to largely negate both the carbon offset and cost benefits of solar.

- kragen 7y agoClearly you haven't done the calculations. And what is this nonsense about negating carbon offsets?
- keanzu 7y agoPowerWall scales fine, like most things do, with infinite money. All you need is a ~$10K [1] investment (including installation) for every house every 10 years (warranty period) and voila - grid scale! Oh warranty doesn't cover normal degradation of energy capacity over time.
