G20 & PARIS ACCORD.

Ohmigod! Trump has cancelled the US part of the Obama Paris Climate Accord!

All the other nations (Including Australia) love the accord and want it to continue!

This means that the US is NOT going to contribute $100 billion to help the poor countries.

And it also means that the rest of the world is not going to get a share of that $100 Billion.

Boo Hoo!!!

I guess we in Australia will just have to step up to the plate and pay the share the US isn't paying.

LITHIUM ION 100MW/129 MWH BY TESLA.

And it only costs $550 million?  (That is $4,300,000 per MWH stored)

Normal cost of a MWH (from Wind or Solar) is around $120. (Coal is cheaper).

Lithium Ion batteries have a half life (i.e. lose 50% of their charge capacity) after 1,000 discharges.  That means (If you throw them out when they lose half their power) that it costs $4,300 (divide $4,300,000 by 1,000) to store each 1 MWH which was worth $120.  That means the amortised delivery cost is $4,420 per MWH to obtain electricity from a Lithium Ion battery.  (At your meter that works out to ~$4.40 per KWH, which is probably ~ 30 times what you are currently paying.)

To power all SA homes for 24 hours at that rate Wetherill would need to outlay ~$100 billion.  Which is 10% of Australian GDP.  And the batteries would probably have to be replaced every 10 years (depending on usage).

I am so glad we in NSW do NOT have a Wetherill Government!
