Pumped hydro involves using surplus energy to pump water uphill to a storage reservoir. The water can then be released downhill to generate electricity on demand.
The Australian Renewable Energy Agency has told Malcolm Turnbull pumped hydro could be the key to unlocking "cost-effective large-scale energy storage that can stabilise high levels of renewable energy in the national electricity grid", such as in South Australia.
"Pumped hydro is the only mature, bankable technology that is readily available at scale," ARENA chief Ivor Frischknecht said.
"However, the lead times are long. Most PHES projects take between four to seven years to develop and construct with the majority of cost associated with civil engineering and construction."

“Greenery bursts forth in 2017 to provide us with the reassurance we yearn for amid a tumultuous social and political environment. Satisfying our growing desire to rejuvenate and revitalize, Greenery symbolizes the reconnection we seek with nature, one another and a larger purpose.” – Leatrice Eiseman, executive director of the Pantone Color Institute
The Pantone Color Institute recently announced Greenery as the 2017 Colour of the Year. The Institute describes Greenery as “a fresh and zesty yellow-green shade that evokes the first days of spring when nature’s greens revive, restore and renew. Illustrative of flourishing foliage and the lushness of the great outdoors, the fortifying attributes of Greenery signals consumers to take a deep breath, oxygenate and reinvigorate.”
Over the past five years, we have seen an increasing proliferation of plants in our urban environment with communal vegetable and herb gardens becoming commonplace, foliage spilling from multi-story buildings and green walls surprising us in unexpected places. In interiors, we’ve seen the resurgence of indoor plants and green walls as features in the commercial interior landscape.
The more we become immersed in modern life and our high-tech world, it seems the more we crave contact with the natural world.
