World’s largest battery is being built

Decades ago solar panel installation was either pay upfront or monthly for a few years i.e pay around the same amount would normally pay for electricity for a few years to buy the panels and then free electricity from there (could be why corrupt greedy freemasons do not like people having solar panels on their roof) Some great oz politicians subsidised installation for a few years to boost the smart electricity grid.

Smart electricity grids where each house, school, public building, skyscraper has its own solar panels and batteries and sells excess electricity back to the grid reliably provide electricity. Attach a small solar panel to every traffic light etc, it’s easy and low cost to implement.
