Tesla/Solar City Energy Storage Solution System Is In The “Pilot Program” Stage Today

Home battery storage taking off in Australia

This article argues that Australia has all the ingredients to be the world’s leading market on battery storage: Lots of solar, high prices, and a consumer base that is independent, cost conscious and distrustful of incumbents. It’s from Renew Economy.

There is no doubt that Australia is going to be at the leading edge of battery storage, that is because of the huge number of solar panels already on household rooftops, the high electricity costs (particularly network charges), and the excellent solar resources.

But there is more than that behind the reason so many global battery storage developers are targeting Australia as their first big market, and a test case to the world. It is also about the unique approach Australians have to their energy supplies, a healthy cynicism about the incumbent utilities, and a yearning for energy independence.

Australia, according to Greg Bourne, the chairman of the Australian Renewable Energy Agency, is about to enter the “iPhone” moment in battery storage.

“It would appear that energy storage has arrived!” Bourne told the Australian Energy Storage conference in Sydney. “Of course it’s been around for quite a time in some form or other but just like 2007 was the iPhone moment; 2015 might be seen as the Tesla moment!”

Technical advances making wind power viable everywhere

An interesting and detailed discussion of the technology behind wind power and how it’s changing

Wind power is often described as relying on “mature technology” and, in many contexts, that’s correct. Today, well-sited wind farms in the US and EU generate electricity at a lower cost than coal.

But numerous difficulties remain with the way we build wind turbines, and these difficulties raise the price of the turbines, which in turn determines where they can profitably go. High turbine costs mean that, unless the wind at a site is quite strong, there are typically better ways to spend money.

Fortunately, while wind is mature technology, it hasn’t reached an evolutionary dead end. Plenty of incremental changes can make wind even more affordable—and in many cases, the necessary technology is already being tested.
