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 $billions to help
the poor countries.
Regrettably Obama has already handed over $! billion.
And it also means that the rest of the world is not going to get
a share of those $Billions.
Boo Hoo!!!
I guess we in Australia (i.e. Malcolm and Bill) 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.(DECEMBER
UPDATE)
Back in July I
wrote that the 100MW battery would cost $550 million.
Mea Culpea. The
cost of $550 million was apparently the amount set aside for renewable
energy. As of today (2nd December) the South Australian premier
refuses to say how much the battery cost, apart from saying "much less
than $200 million".
So lets imagine
"much less" is ~$50 million. In which case, just divide all my
calculations below by 11, {See bold numbers in curly brackets}
And it only costs $550 million? (That is $4,300,000
{~$400,000} 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
{$400} (divide by 1,000) to store
each 1 MWH which was worth $120.
That
means the amortised delivery cost is $4,420
{$520} per MWH to obtain
electricity from a
Lithium Ion battery. (At your meter that works out to ~$4.40
{$0.52} per
KWH, which is probably ~ 30
{~3
times} times what you are (or should) be currently paying.)
To power all SA homes for 24 hours at that rate Wetherill would need to
outlay ~$100 billion.
{$10billion}
Which is 10%
{0.7%} 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!
