"Renewable energy player Genex Power says if it can get its Queensland wind project off the ground it might have the “holy grail” of renewables in Australia.
The $88 million company (ASX:GNX) has already completed — and is
generating cash — from stage one of its Kidston Renewable Energy Hub in far north Queensland — a 50 megawatt (MW) solar project.
Genex is aiming to achieve funding for stage two — a 250MW pumped storage hydro project and expansion of the solar project to 270MW — by the end of this year."

I get a bit sceptical when holy grail is mentioned because I don't think there is such a thing (where renewable energy is concerned).
What I do believe in is that there will be many and varied renewable technologies that will take us forward.
Pumped hydro (with solar and wind) seems a fairly solid bet to be one of them.
