Why should I use this instead of Template class from string
Also, they're already wealthy, they have what matters in the foreseeable future.
This is unequivocally not an endorsement of their choices.
I'm also convinced that separating generation and storage is simply an awfully, comically bad idea: generation that needs storage - solar and wind - is DC, storage is also DC. Transmission is usually AC or at least goes through AC/DC conversion at some point.
Why wasting a lot of additional energy to store it by doing an extra unneeded AC/DC conversion which happens if storage is separate from generation? Instead of storing DC energy as it is produced and discharging it - by converting to AC and feeding into the grid - as it is needed?
What does this mean? Can you give an example?
