Letters to The Advertiser – Store the power
Store the power, MARK SCHUBERT, Glynde, 3 Aug 19
KYM Bray does not believe renewables can supply all our electricity needs, presumably because there are times when the sun doesn’t shine or the wind blow (“Need base power”, The Advertiser, 31/7/19).
For renewables to work full-time, energy needs to be stored.
Present viable energy storage systems are rechargeable batteries; hydrogen, from electrolysis of water; heat (eg hot-water tanks and concentrated solar thermal), and pumped hydro – still the most economical, reliable, long lasting, and efficient bulk-energy storage.
With pumped hydro, water is reused by pumping it uphill using excess power, and then letting it flow back to generate power in times of shortage, as is done now in the Snowy Mountains Scheme in southeast Australia.
Costs of these storage systems are reducing as research continues and mass production ramps up.
I believe we can soon use renewables backed with storage to supply all our electrical power, reliably, economically, and with minimal CO2 emissions. I believe in physics, not fairies, Kym.

The Road to War brings a sharp focus to why it is not in Australia’s best interest to be dragged into a war with China which will almost inevitably go nuclear very quickly. The filmmaker has interviewed some of Australia’s senior foreign policy analysts who have vast experience behind them in analysing what really is going on here as the United States rattles its sabres with China. And sets us up to be its proxy, like the poor Ukranians have been fed into the Meatgrinder. So America can remain the Top Dog. The Road to War reveals how the United States through its spy base at Pine Gap and by stationing six nuclear capable B52 bombers in the Top End (without permission from the traditional owners) is making Australia a prime nuclear target if the current war of words suddenly melts down into full scale war.
The Road to War shows the implicit connection between Carbon emissions (the US military uses a whopping 70% of America’s annual petroleum to move its armies and vast War Machine around the globe to its 800+ military bases..but under a loophole wangled at Kyoto, the US military does not have to report its C02 annual emissions). The Road to War starts screening at selected cities and regional centres in March. See the trailer end for details.
