This is indeed the future, I suggest you do some research on the early electric cars. And why gas cars eventually dominated market share. It is all about them $$$. But why have $$$ when it is not good for the planet. Every bit helps, whether buying a Tesla or simply having solar panels on your house for your electricity at home.
A good reason to do so and motivate those that read this comment: If you produce more electricity than you use at home, you can sell it to your neighbors.
