To store energy, we have to do quite a lot of things. Of course, this is all dependent on the energy being stored. For example, the Tesla corporation has something known as the “Powerwall.” It stores the energy you are not using and can even store solar energy for backup power if you start to run out for some reason. This is quite useful for times when your power goes out, such as during a storm. Nanotechnology will be able to blow this out of the water, where energy storage becomes even greater. Transmission of energy will also be an area where nanotech might be a huge asset. Yet there is always an issue where environmental problems come from this, as well as the possibility this could become a human hazard.
