Electricity is vital to our everyday life. We assume that there will continuously be enough for us, but this is not always true. Every power plant has an upper limit to the amount of electricity it can generate. If the demand is greater than the supply, then the brownouts and blackouts occur. As our human population grows the demand for electricity also increases.
The effects of rotating brownout will be very severe to our modern way of life. Our human civilization has only existed with the help of electricity for a very small slice of its overall timeline.

When in or around cities, there are special consequences during power outages. Most urban and suburban locations are very highly dependent on uninterrupted electricity.

While the majority of power failures from national grids last only a few hours, some blackouts can last days or even weeks, completely shutting down production at companies and critical infrastructures such as...
