RE:Tesla is bringing its home batteries to CanadaIf you care to do the calculations you will see that it would take the entire current world output of Lithium Ion batteries to provide a small Province like New Brunswick with just one day of back up battery power. There is no possibility or likelihood that battery storage will ever replace baseload nuclear power. Plus you would need to cover most of the Province in windmills.
Some people here and unfortunately much of the media do not understand the scale of electricity generation. It is taken very much for granted but the power we rely on every day is supplied by highly complex grid systems to which are tied large base load power stations. That is what gives it stability. To replace all of that with batteries and intermittent power supplies to charge them is pie in the sky. Whether you are an enthusiast or not you cannot argue with mathematics.
There is also the slight problem of Cobalt. Lithium Ion batteries - while they do indeed use Lithium over which there has been much hoo haa...also use Cobalt...lots of it. Unfortunately most of the worlds production of cobalt currently comes from the Congo...which by all accounts is not the most political stable or corruption free nation.
I contend that basing ones entire economy on the production of one metal from one nation is about as poltically inept as you can get....even for Mr. Musk.
Now I can see supercapacitors making an important contribution but not L-ion batteries. Not a chance.
