I don’t think Australia needs them  at all to generate  our power , because if we actually be smart and put small vertical wind generators along side and in conjunction with solar panels on every  existing power pole in the country,
 I believe we will generate  most of our country’s energy needs for now and for well into the future .
It could be the national electricity company ,
and would once up and running  it will create  lower electricity prices , and be as environmentally friendly as as we possibly can be ,
we could design and manufacture the units here creating a new industry and real tangible jobs and sure up Australia’s energy production for a renewable energy future
