Advances in technology, and the ambitions of countries willing to harness it, are proving that the transition to 100% renewable energy is not only possible, but cost-effective, too. Investment and development of solar and wind infrastructure, as well as energy output, is booming after a 3-year slump—a hopeful sign of things to come.

the advances with Brushless motors and lithium polymer batteries has come a long way in recent history
Your knowledge is also flawed. are you not aware that LI PO batteries have a shelf life of between 2-3 years even if they are not used?
batteries also have to be charged and the charging process if just a transformation between one form of energy into another form, in each transformation there is loss.
By saying that batteries can supply energy you are neglecting the loss that is inherent in the system. Energy can not be made only transformed from one medium to another, it is a 'loss" system no mater how efficient the system is.

I hope those who think nuclear is the way to go would be happy to live next to nuclear power station. But in any case, building them is not cheap either.
