an interesting read on Solar/CC etc

[nzoomed]

And then there's our current government's energy strategy  

I dont know if lake Onslow was the best value for money with the way solar is going, but at least it appears the government are focusing on offshore wind and solar which is somewhat reassuring but we need a long way to go.
The other disadvantage I see is the North island has the highest electricity demands and getting it sent up all the way north creates additional problems that Transpower is still working on upgrading with the HVDC link, etc.
With the costs of solar coming down its possible that widespread solar farms might be a viable option.
Then ive been hearing about gravity batteries which look rather interesting and even compressed air, might actually work out better than the lake battery?
