Huge solar project in limbo as Newman pulls funding
March 29, 2012
The new LNP government plans to pull funding for the Solar
Dawn solar research and power plant at Chinchilla.
The first chance to test whether solar thermal energy can
provide large-scale alternative power in Australia may be in
doubt under the new LNP state government.
The incoming Queensland government wants to pull out of an
agreement formed by its predecessor to provide $75 million
towards the $1.2 billion Solar Dawn solar research and power
plant at Chinchilla, west of Toowoomba, Premier Campbell
Newman said yesterday.

Pipe Dream?
"It is time the Greens stopped
deliberately misleading the Australian
public with their claims that Australia
can move to 100 per cent renewable
energy within a decade," Mr Ferguson
told The Australian. "They are living in
fantasy land if they think this can be
achieved."

Will the falling price of solar PV make
PV with pumped hydro storage cheaper
than solar thermal with storage?
We don’t know, but watch this space!
Whatever advances are made are going
to make renewable energy even
cheaper than the ZCA plan!
Australian Sustainable Energy
by the numbers
by Peter Seligman
This is another approach to renewable
energy in Australia which complements the
BZE project – although it was done quite
independently.
Peter Seligman looks in some detail at the
possibility of pumped hydro storage systems
with dams on the high sections of the
Nullarbor coast.
