The problem with "power outlets" is that they're heavily dependent on fossil fuel power plants. Since it is an unpredictable variable load, even more so than you think. Which is why it is really a transitional solution. From the beginning, it was about replacing distributed emissions with centralized ones, usually far away from cities. At some point, it became this green fantasy that could seriously replace fossil fuels. It is highly unlikely to do so in reality. Even BEVs will need hydrogen power plants to solve variable grid load problems. Eventually, you'll realize that hydrogen is a mandatory part of the problem, and the battery becomes redundant if not a negative.
