I often see posted about how covering a relatively small area in a desert with solar panels could power the world – but transferring that energy is too difficult. Why can’t we just use that to charge batteries and ship them places/ everywhere?
In: Physics
Shipping batteries needs a lot of energy. It is much cheaper to transport electricity by cable.
But that also has his price based on the resistance of the cable.
It’s called Ohms Law.
A 100km high voltage line will lose between 3 and 7 % of the energy.
