How can a university dormitory generate electricity without electricity? There was only one lamp out of power all day, because the school said there was no wire in the dormitory for safety and I wanted to steal it. The generator will provide it with energy. What power are you going to use to drive the generator?

Manual generator or pedal generator, you have to always use manual (pedal) generator to generate electricity. Can you stand it?

You can't stand the noise and pollution caused by driving the generator with gasoline or diesel.

Using solar energy to store electric energy requires installing solar panels and batteries, which are expensive and your economic conditions are not good.

Then don't use electricity.
