It would be too dangerous, obviously they store a fair deal of electricity in electric plants, but those plants are already huge and highly secure. More electricity would pose extra risks and more space, often unavailable.

To add to the previous post, capacitors can also store electricity, although batteries are the best source for storage, while capacitors are well suited for, among other things, providing a quick increase in power when the load suddenly increases. . . You can store enough power to run a large building by using large banks of batteries for ~20 minutes. Usually that is meant as a temporary measure until generators are brought online. The trouble is that you need so many batteries that maintenance and safety become serious problems.. . In summary, the technology we have is limited. Even the newer Lithium-Ion batteries, while they can store quite a bit of power for their size, are prohibitively expensive on a large scale.

So far all we can store electricity in is batteries. The chemicals make them bulky and sometimes dangerous.

Try to think of a battery. As you should know a battery is one of the simplist electricity storage facilities. An average battery stores like 1.5 voltes. It's size is similar to a size of a human fingure. Ok.. the larger the electrical amount in a battery the bigger it gets, which is very rational. Then imagine if you want to store 1000000 voltes, which is conciderd huge, in a battery. You can imagine the size of this battery.. And as you can see it is very not-practical and unsafe to do this.. I tried to make the answere as imaginable as I could because I don't know the age of the person asking.

It can. However it is not cost effective or needed.. . Theoretically you could build a battery or capacitor the size of the empire state building but what for.. . Now if you’re thinking of “capturing” lightning bolts and storing them in a big battery the problem of too much at once comes into play. The current conductors we have can’t handle that much voltage they melt or burn.
