We use energy to not only heat our human-made structures but we use it to cool them as well. Energy is necessary for getting up out of bed, walking down the street, or even lifting your finger. It's also necessary in abundance for all types of modern conveniences, from light bulbs to appliances to vehicles.
It's better because different social medias are used for different things. (ex: ig/fb are more for connecting with people you know in real life, but yootube is for sharing videos with people all around the world)
