What is the main problem of electricity transmission?
Power loss along transmission lines.
What can extreme natural events cause?
Power outages and widespread blackouts.
What tasks does energy transportation imply?
It implies important mantainance tasks and constant control and coordination of transmission devices.
How can the energy loss depend on the time of the day?
When energy demand is high, power loss is higher (daytime). When it is low, power loss is lower (nighttime)
Describe how power is lost over the transmission lines.
The transmission wires heat up with electricity and some energy is loss in the form of heat.
How can power loss be reduced?
With the use of superconductive materials.
Why is the use of superconductive materials not a good solution for energy loss?
They're too expensive.
Does the amount of lost energy depend on the voltage?
Yes, it does
What phenomena can affect power distribution?
Extreme natural events (hurricanes, storms and floods, extreme temperatures)
