Why is friction a nuiscance in a pulley?
It wastes energy. However, SOME friction is also needed, or the pulley would just slip.

How do you save energy from cloud lightning?
I have no idea.....stuff happens and then you save energy
How can conserving energy helps prevent shortages?
If you save energy you can't have a shortage because if a shortage is about to happen the energy that you save will take over the energy that is running out.
1 pulley system more efficient then a 2 pulley system?
Efficiency is the proportion of energy usefully used. Using a pulley system does not use less energy it just changes the ammount of force. Pulleys do have a small ammount of friction so having just one pulley would be more efficient. (but not much more)
