Electric vehicles and coal stoves - a tale of two Chinas
In February, I travelled through China and witnessed the beginnings of what may well be an electric vehicle revolution in Shenzhen. Bolstered by generous subsidies, the majority of Shenzhen's taxi and bus fleet is now powered by electricity. On the other side of the country, Changchun's freezing weather and suppressed economy is putting the brakes on the road to a pollution free future for northern China. The question is whether technology and aggressive government policies will usher in a new era of clean skies and cheap rides or a divided China where the rich Southern provinces blaze their own trail.

Non-Financial Benefits of Energy Management
We often evangelise about how energy efficiency can save you money, but what if you don't have a large electricity spend or you have so much cash flowing in that a big electricity bill doesn't phase you? What's the point of introducing energy efficiency measures if the savings don't interest you?

Should We Use Blockchain to Incentivise Energy Efficiency?
The meteoric rise of Bitcoin, Ethereum, Dash and other cryptocurrencies this year has placed blockchain well and truly in the hype phase of the Gartner Hype Cycle. Should we jump on the bandwagon and issue our own token for energy efficiency? Whilst "NegaCoin" is an appealing idea, there are several major barriers - the oracle problem, lack of demand/liquidity, the power suck of current blockchain technology and the lack of skilled developers. For now, it's going to sit on our backlog but we'll be watching this space.

The Queensland state election is on this Saturday and the Adani coal mine is a hot campaign topic. Green groups are advocating strongly to "Stop Adani" but I'm not so sure that's the right message. Hasty solutions from either side won't work. What we need is a long term plan for how to generate secure employment for far north Queenslanders for decades to come. With automation threatening to decimate blue collar jobs, it's time to start thinking about how to retrain and upskill resources sector workers.

Transport Priorities in Sydney
While a massive $45B is being funnelled into WestConnex and associated roads, a paltry $60M/year is celebrated for spending on bike infrastructure while enforcing draconian fines. Active infrastructure for walking and biking comes at a low cost with vast benefits to health, local and city economies, jobs, and traffic congestion. It's high time the state government resets its focus on public good to fund projects that deliver good value for money, return urban space to people instead of cars, prioritise human activities, and increase public transport options to expand the currently limited capacity.
