Off grid? That's one way to go.

  Australia is leading the world in rooftop solar adoption. By June 2025, 4.2 million rooftop solar systems had been installed nationwide  representing 26.8 gigawatts of clean power generation capacity connected directly to local electricity networks that serve homes and businesses.

   “In the evenings homes typically consume power, which flows from large power generation plants, such as wind farms, hydroelectric, coal and gas-fired power plants. Let’s call this the ‘low-tide’ time in local electricity grid operation,” he said.

  “In the middle of a sunny day, however, today about 40% of Australian homes generate their own power from rooftop solar panels. When the rooftop solar generation exceeds the power consumption in the houses, the excess power is ‘exported’, flowing back to the grid, supplying other homes and beyond. Let’s call this the ‘high-tide’ time in local electricity grid operation.”

Grids are useful to balance out sources and sinks, make battery farms economical at scale. You do need smarter grids to deal with phase imbalances.
