What we use energy for?
electronics,lighting,heating,warm showers,electrical appliances,clock's and more...
Lightning
Lightning is the most powerful types of electricity. Sometimes the lighting reaches 100kA. This peak last for 30 microseconds. Does this mean that you get 100TW in 30 microseconds, and this is enough to power a 100 watts lightning bulb for two months, and that if the lightning lasted for about 1/6th of a year, it would have provided enough energy for the whole world?
Energy saving light bulb
If you Light your home using the same amount of light for less money. Upgrading 15 of the inefficient incandescent light bulbs in your home could save you about $50 per year.
Normal light bulb
This type of light is the one of the most expensive lighting that is why you should not use it
What if we had no energy/electricity?
We would have No Ipads,Iphones,Ipods,laptops,TV's,microwaves,ovens,vehicles,blenders,Lights,heating
etc....
Some people would go crazy if we had no electricals
