We’re investing heavily in urban greening, so how are our cities doing?

The Conversation, 27 September 2017
Governments at all levels invest a lot in greening Australian suburbs. Yet, in a recent report, we show that the greening efforts of most of our metropolitan local governments are actually going backwards.
This is a puzzle, as greening has clear environmental and economic benefits. The environmental benefits are obvious and relatively easy to count. For private home owners, numerous studies have linked greening to a range of economic benefits from energy savings to higher house prices. So how do we explain the loss of green cover?

Australia wind energy’s record day of production in August

REnew economy, 22 September 2017
Australia set a new record for wind energy production on August 16, producing an average 3,629MW over one 30 minute settlement period to the National Electricity Market (which doesn’t include W.A. or the Northern Territory). The record, noted by Hugh Saddler in The Australia Institute-sponsored monthly update of emissions and energy supply, meant that wind energy counted for more than 17 per cent of total grid demand.

Bike share schemes may seem a waste of space but the economics makes sense

ABC News, 19 September 2017
Have you ever walked past (or tripped over) a shared bike and wondered how it’s possible for the business to survive with a ride costing as little as $2 per half hour? While bike share schemes attract controversy in some places, the economic models behind such schemes actually have more to do with data mining, advertising and turning a profit from interest on the deposits than from the bike rental itself.

Airbnb and empty houses: who’s responsible for managing the impacts on our cities?

The Conversation, 19 September 2017
The Airbnb and empty house phenomena and their presumed links to housing and rental prices have attracted considerable media and political attention. The ABC points to the “dark side” of Airbnb and its effect on long-term rental prices. Empty houses are being linked to higher housing prices and to foreign investment, most often Chinese investment. The Australian headlines that “China buyers raise ghost town fears”. The Commonwealth and state governments are seeking to regulate the phenomena. It is questionable whether they should and even whether they understand the data and trends.

ESB chair says demand response could kill need for new power plants

The chair of Australia’s newly formed Energy Security Board, Dr Kerry Schott, has stressed the importance of demand response in meeting the nation’s energy security and affordability needs, telling ABC Radio that if we could harness the technology effectively, we could “all stop worrying about building new plants of any description.”

Rooftop solar pushes South Australia to record low grid demand – in spring!

ReNew Economy, 13 September 2017
Spring is barely two weeks old and the sun had yet to pass the spring equinox (September 23), but already South Australia has set a new record low for electricity demand from the grid, thanks to its increasing supply of rooftop solar PV. The record low demand – 786MW – was reached around 2pm on Sunday and was cited by Australian Energy Market Operator chief executive Audrey Zibelman as an example of how the grid is transforming.

Google architecture and what do you see? And what’s a building without people?

The Conversation, 13 September 2017
Think about where you spend most of your day – home, your office, or university. How does this space make you feel? What do you love (or hate) about it? Our buildings can help or hinder our health and productivity. For example, we can be affected by daylight access, air quality, connection to nature and acoustics. Most complaints about a space – about temperature, noise, odd smells or even how exposed we feel – relate to these factors.

Renewable energy generates enough power to run 70% of Australian homes

The Guardian, 28 August 2017
Australia’s renewable energy sector is within striking distance of matching national household power consumption, cranking out enough electricity to run 70% of homes last financial year, new figures show. The first Australian Renewable Energy Index, produced by Green Energy Markets, finds the sector will generate enough power to run 90% of homes once wind and solar projects under construction in 2016-17 are completed.

Green for wellbeing – science tells us how to design urban spaces that heal us

The Conversation, 28 August 2017
One in five Australians will suffer from a mental health issue this year and living in a city makes it far more likely. Research shows that city dwellers have a 20% higher chance of suffering anxiety and an almost 40% greater likelihood of developing depression. Promisingly, however, research has also found that people in urban areas who live closest to the greatest “green space” are significantly less likely to suffer poor mental health.
