How do Blackouts Occur
Blackout can happen for many reasons. Some of them would be: problems at power stations, damage to equipment at power station, or certain over uses of energy including using your air conditioning or heater on high all day and night.
The Science behind Blackouts
The source for our electricity is HUGE, gigantic power plants. Usually power plants can burnout is too many people use electricity at the same time consistently. For example, if a heat wave were to hit New York and everyone was using their air conditioning on high all throughout the day and throughout the night so they can stay cool, their would be a power outage because of all the electricity consumed. Another way of having a blackout would be if the power plant was in need of maintenance and take the power off line for a little and other electric currents can pick up that the power is off line and actually cause a blackout.
