The case for pragmatism, not dogma.
The University of Melbourne is the first institution in Australia to have its nitrogen footprint calculated – it’s 139 tonnes per year, mainly because of food production, energy use and transport.
Since the federal government started setting fuel economy standards, US-built cars have doubled their fuel efficiency, saving money for consumers and reducing pollution.
We must develop the capability to meet our computing needs while using much less power and producing negligible heat waste.
Lowering your carbon footprint by living off-grid is a sustainability dream. But how possible is it using current technology?
Those on low incomes get less back from home improvement schemes than they pay in government charges.
Buildings are central to creating more sustainable cities, and green ratings are often used to assess how well a building measures up against this goal. But the current system has serious flaws.
While new buildings may be the glamorous eco-home pinups, retrofitting existing homes is the main game when it comes to creating energy-efficient, comfortable housing stock for all Australians.
New research shows that computers, streaming video and other digital technologies are helping Americans spend more time at home and less out shopping and commuting, yielding measurable energy savings.
We use our fridges, washing machines and air conditioners every day. That means that we should consider much more than the up-front retail price when choosing to invest in a new one.
There’s little point in saving electricity at times when the marginal cost of generating it is effectively zero.
Trying to keep cool this summer while not blowing the power bill? A new mobile game aims to encourage energy efficiency - and research shows it can be more effective than simple advertising campaigns.
The extra energy used to mine and transfer Bitcoins may simply be a price the currency has to pay for being secure and anonymous.
We can make up 70% of Australia’s projected gas shortfall simply by improving energy efficiency and sensible use of gas alternatives.
Boosting state support for energy efficiency would be a fairer way to reduce bills.
The law says that newly built houses should have a six-star energy rating, to help residents afford their heating and cooling bills. But some builders seem to be findings ways around this requirement.
Aged-care units can be a lottery of comfortable versus uncomfortable temperatures, depending on the building’s construction and where you live within it. That needs to improve.
The invention of silver and plastic-clad roof panels that can cool themselves down even under the Sun’s full glare promise to make air conditioning much more energy-efficient.
Why go to all that bother when you can just half-fill the kettle?
