Electrical energy is observed in nature, in electrical storms that generate great quantities of energy, which makes it very difficult to store it and take advantage of it for different everyday life uses. There are many types of energy like wind, geothermal and hydroelectric energy, among others, which allow us to obtain electrical energy…Could you imagine your life today without electricity? What would it be of your videogames? Could you listen to music, watch TV, connect to the internet, and keep your food refrigerated? Could you charge your cell phone or speak on a wireless phone?
