In Tesla’s view, such storage systems could become part of a fossil-fuel-free lifestyle in which people can have solar panels on their roof generating electricity to power their home and recharge their electric car batteries.
I wish we talked more about the sources of the energy that will be stored in those batteries. Solar and wind are excellent sources but we’re still very inefficient in capturing and storing most of what is generated especially in small scale.
I think the problem right now is just storing the energy we can create. Solar cells are quite efficient, and so are wind turbines. The only problem is what to do when you don’t have any wind or sun.
